ABSTRACT
The Vietnam Low Carbon Rice Project - VLCRP is a pioneering community-based low carbon rice farming project that creates the practical and measurable changes for the rice production in the Mekong Delta. These changes have been documented through their on-farm research and intervention activities for 11 crops in Phu Thuong Co-op, Phu Tan district of An Giang province and Kenh 7b Co-op, Tan Hiep district of Kien Giang province. With the Participatory Technical Development approach, the VLCRP’s low carbon rice farming protocol namely 1Must 6 Reductions (1M6R) has been piloted, and more than 500 farmer households have been trained to cultivate rice on an area of 540 hectares, for 3 crops per year. Over the two communities were VLCRP has worked, rice farmers that have adopted 1M6R have reduced their seed density by 50%, fertilizer by 30-40%, water irrigation by 40-50%, pesticide by 30%, and labor costs by 20% while increasing their yield from 5-10% resulting in an increase their net profit by 10% to as much as 60%. The project also has implemented its community development package with affirmative gender and women empowerment activities targeting the improvement of women’s livelihood, market linkages and rice value chain improvements. All crop results were communicated with local governments at the commune, district and province as well as policy makers at national level to support policy changes. The scientific data are presented in 3 research reports which accompany this Summary Report.
1. Background context
Vietnam has a largely agriculturally based economy, ranked 2nd
for rice export, providing
16% of the total rice export commodity (FAO, 2008). The Mekong Delta (MD) is the
country’s main rice bowl with approximately 3.9 million hectare of cultivation areas; in which
about 1.85 million hectares are in rice cultivation. In 2013, MD rice export reached 25 million
tons which accounted for approximately 77% of the total rice production of Vietnam and
contributed 90% of Vietnam’s rice export (GSO, 2014). The rice production sector is the main
livelihood for more than 70% of rural populations and contributes substantially to the export

turnover and the GDP. Vietnam’s agricultural strategic development plans for 2030
recognizes the MD as the strategic area for ensuring the national food security.
In recent years, the rice production and livelihood of rice farmers has been facing numerous
challenges. Rice prices have dropped while input costs have increased. It has been estimated
that more than 1,140,000 farmer households’ livelihood are threatening due to the very low
income from agriculture. Rice farmers have overused fertilizer and other inputs by
approximately 30% and face adverse weather conditions including drought, flooding, salinity
increases and soil erosion. Other problems include limited knowledge and poor farming
techniques, increased soil pollution, and small-scale production with little or no linkage to the
market.
The mandates to increase the income of farmers and foster rural development are major
targets of the Vietnamese Government. These mandates are driving the national policy
framework for restructuring and modernizing Vietnam’s Agriculture, and achieving
sustainable rural development. Given this context, applied research and wide-scale application
of an advanced rice farming technique is needed to increase economic effectiveness while
reducing the negative environmental impacts.
2. Objectives, project size and location of the VLCRP
With the support of the Australian Government under the Community-based Climate Change
Action Grants, the Environmental Defense Fund (EDF) collaborated with the Mekong
Research Development Institute (MDI) and the Advanced Laboratory of Can Tho University;
the Department of Agriculture and Rural Development of An Giang and Kien Giang and their
Extension Centers to pilot the community-based project entitled “Vietnam Low Carbon Rice
Project – VLCRP” during the period of 2012 – 2014.
This pilot project was designed to achieve the 3 main objectives:
1. Improve community livelihoods by training small-holder rice farmers in
agricultural practices that decrease production costs, maintain or improve yields,
provide environmental co-benefits, and create additional income streams from
sales of carbon credits.
2. Demonstrate a community level climate smart agriculture pilot that (i) trains
small-holder rice farmers to document changes in agricultural practices that
reduce GHG emissions and (ii) facilitate the higher income generation from
better rice quality, market linkages and potential to sell the resulting carbon
credits on the voluntary carbon market and (iii) promotes community
development with gender mainstreaming for empowering women and the
marginalized members of the community.
3. Build stakeholder and community capacity for scaling up the project and for
transitioning to a broader array of sustainable funding sources over time. This
includes the dissemination of project results by stakeholder advocates to policy
makers for broader adoption of the approach.
VLCRP worked and built up capacity for the DARD and their Extension System as well as
more than 500 small farmer households in the 540 ha paddies in Phu Thuong Co-op, Phu Tan
district, An Giang province and Kenh7b Co-op, Tan Hiep district, Kien Giang province. Over
the period of 2.5 years, VLCRP completed a total of 11 crops in the two Co-ops.
3. Major results and achievements
85
The 1M6R low carbon rice farming protocol is built on and further refined from the 1 Must 5
Reductions farming techniques. (1 Must means must use certified seed; 5 reductions include
the reduction of seed density, fertilizer, pesticide, water irrigation and post-harvest lost.)
VLCRP has tested, piloted and applied a comprehensive farming package to the 1M5R
techniques, including a crop-specific alternate wet dry water irrigation scheme and
appropriate fertilizer application rates that have produced positive economic and
environmental co-benefits. As such, the resulting VLCRP low carbon rice farming protocol
has achieved a 6th
reduction – a reduction of environmental pollution that includes green
house gas emissions and thus has been renamed “1 Must 6 Reduction” low carbon rice
farming technique. Since 2010, the 1M6R techniques have been further refined to prove its
efficacy in terms of economic, environment and social development.Based upon the
encouraging results and achievements from the last 2.5 years, the Department of Agriculture
and Rural Development of Kien Giang and An Giang have extended and scaled up the
application of VLCRP’s 1M6R low carbon farming techniques to over 1,000 ha since the
Winter-Spring crop of 2015, in their Large Scale Rice Production Model. They are also
promoting the adoption of the 1M6R technique in other communes and districts of Tan Hiep
and Phu Tan of Kien Giang and An Giang provinces.
3.1. Major results
Over the last 11 crops in both An Giang and Kien Giang, the application of the 1M6R farming
protocol have continuously delivered the triple wins of economic, environment and social
development. These aspects are measured, verified and reported as following:
a) Economic development and livelihood improvement for rice farmers
Farmer’s incomes have increase from 5-60% through the reductions of input costs by reduce
50% seeds, 15-30% fertilizer, 30-40% chemical pesticide/herbicide, 40-50% water irrigation
and 20% labor cost. On average, rice yield increase from 10% and net profit increase from 10-
15% per hectare as compared to the farmer’s conventional practices.
b) Environment and Food Safety; Protection of Public Health, Water Resources and
Ecological System
By reducing chemical pesticide use, not only is production cost reduced, but this practice has
helped to improve the quality and safety of the rice. VLCRP has collected rice samples
randomly from its 1M6R model and the conventional practice model for laboratory test to
measure the heavy metal and chemical residues. Results have showed that the rice from
1M6Rs met the WHO.standard food safety. The nitrate was found to be 4.97 -6.76mg/kg
which is far lower than the allowed nitrate residues from fresh vegetable, drinking water and
food for infant and mother in accordance with the WHO standard. Concentrations of
Propiconazole, Tryciclazone, Acetamiprid, lead (Pb) and cadmium (Cd) were below
detectable levels.
When apply the 1M6R farming protocol, rice farmers have better opportunities to reduce their
health risk hazard by reducing direct interactions with toxic chemical, and protect their
ecological system including the useful insects and fish. Many farmers in the VLCRP project
areas reported to the mid-term independent reviewers commissioned by the Australian
Government that after 3 crops of reduced chemical pesticide use, they have witnessed the
return of fishes/shrimp in their canal and paddies. While farmers’ perceptions have not been
measured to date, VLCRP is considering the possibility of documenting water quality benefits
in its next project phase.
86
To measure the on-farm green house gas emissions, VLCRP applied the US Department of
Agriculture’s GraceNet protocol for measuring the emissions of methane (CH4) and nitrous
oxide (N2O) greenhouse gases for each crop. Results show significant reductions in
greenhouse gas emissions in 7 out of 8 crop seasons where good data was collected over the 2
year project duration. As a result of reductions in overall green house gases emissions, there is
the potential for an additional new income source for farmers from the sale of Certificate of
Emission Reductions – CERs.
c) Social development with Gender and Women Empowerment Integration
VLCRP designed a participatory approach for raising awareness and building up a
community’s capacity which is important for the community’s desire and ability to
voluntarily adopt and practice the low carbon rice farming technique. VCLRP worked with
local authorities and Co-ops to organize and divide each project site into 5 Production Groups.
The field-based extension workers, farmer Group Leaders, and Women’s Union leaders were
provided with a series of Training of Trainer courses which provided a range of subject matter
from primary to advanced level on the low carbon rice farming protocol, and planning and
leadership skills. Farmers and their Group Leaders are thus taking charge of their own crop
planning and management and share successful experiences and practices through their
regular group meetings held 7 times per crop season in accordance with the physical
development stages of the rice. This approach ensures that all farmer households including the
poor, near poor, single women-head of households, disabled and other types of the
marginalized community members have equal opportunities to access to learn advanced rice
farming techniques, equal access to extension services and equal ability to air their opinions
and concerns. During the group meetings, farmers’ Diaries were updated and used to calculate
the profitability at the end of each crop. As a self-help group with the farmers supporting
farmers approach, VLCRP created a sustainable community system for effective application
of 1M6R protocol.
Personalized extension services were provided to the most vulnerable groups of the poor, near
poor, single women-head of households, disabled and other types of the marginalized
community members. Through training and coaching, their knowledge of low carbon rice
farming and household economic management was enhanced, and women and other members
of vulnerable groups were empowered so their voices couldbe heard in either family or
community crop planning and decision making processes. At the same time, VLCRP
collaborated with the Women’s Union to design a user friendly guidebook of 1M6R farming
techniques and integrated its contents to the Women Union’s curriculum for women meetings
at commune, district and provincial level. Baseline data showed that less than 4% and 12% of
women in the community in An Giang and Kien Giang, respectively, participated in
community meeting before VLCRP. After the project intervention, M&E data showed that
86% of women attended and participated 1M6R training and Production Group meetings. To
date, more than 1,200 women have participated in the 1M6R training and group meetings.
The local authorities at the commune, district and provincial level actively monitored,
advocated and promoted the voluntary adoption of 1M6R protocol and provided matching
funds to improve the infrastructure.
3.2. Major achievements
In addition to the economic, social and environment development results, VLCRP was also
able to address the rural development priorities of Vietnam Government and Australian
Government for their international aid program for Vietnam. These are:
87
a) Policy Dialogue to facilitate the Modernized and Sustainable Agriculture
Rice cultivation reform during this critical transition period requires that advanced farming
techniques can increase profitability and sustainability. The successful training in the
techniques of the low carbon rice farming protocol is key to encouraging farmers’ voluntarily
adoption and self-replicate on wide scale. This is a conditional foundation to be sure that the
Agriculture Re-structuring Plan and Rice Reform Plan targeting 2020 be achieved. Given
VLCRP’s encouraging results and achievements, in September 2014, under the direct support
and execution of the Ministry of Agriculture and Rural Development (MARD), VLCRP
successfully held the first national level Policy Dialogue Forum on Low Emission Agriculture
with the participation of relevant technical divisions of MARD, DARD, Agriculture Research
and Policy Strategy agencies, and international organizations including SNV, ADB, JICA,
AgResults and others. As results of this national Policy Dialogue Forum, the International
Cooperation Division (ICD) of MARD updated EDF that the proposals and recommendations
of the dialogue have been used as inputs for rice sector restructuring strategy which MARD
commissions IRRI to undertake. MARD also was able to mobilize the support from the
Vietnam Forest and Delta (VFD) – a USAID funded project to conduct a national-level
review of the implementation of all low-emission agriculture projects in Vietnam. And the
ADB through the TA-REG 8163 Implementing the GMS Core Agriculture Support Program,
Phase 2 have agreed to support MARD to organize a policy dialogue on the low-carbon rice
farming to share experiences with GMS countries aiming at promoting the low carbon
farming practices in the region. In addition, VLCRP Project Management Board actively
contributed and shared methodologies, best practices, lessons learnt and technical expertise on
crop management, irrigation, on-farm greenhouse gas emissions measurement with national
counterparts including Ha Noi and Hue University, Cuu Long Rice Research Institute and
international development partners such as ADB, IRRI, Winrock International,
USAID/USDA and the World Bank.
b) Improvement of Rice Value Chain: creation of Bio-rice and formulation of the PPP
business model
DARD of An Giang and Kien Giang provinces and their Extension Centers supported the
business promotion among the Co-ops and the Rice Trading Companies. Prior to each crop,
the business contracts were negotiated for a favorable purchase price of rice from VLCRP Co-
ops; often from 100 – 300 dong/kg higher as compared to the market price. In addition, rice
farmers also benefited from a no-interest credit offer of 5 million dong/ha or $240/ha from the
Rice Trading Company upon signature of the business contract. These are significant sources
of additional income to rice farmers practicing 1M6R. Moreover, rice farmers did not have to
deal separately with the middle men who often offer lower prices or result in other problems.
There has been a serious proposal from rice trading companies to have a strategic business
plan with VLCRP for improving the rice value chain and developing a bio-rice trade mark for
rice produced from VLCRP’s farming model.
c) Improvement of Livelihood and Empowerment for Women through integrated
community development
In the Mekong Delta, rice farming is the main livelihood and farming decision are often made
by the men. VLCRP baseline data documented this; and although women participated in all
14 major farming activities, from land preparation to the sale of rice at the harvest, male
farmers pre-dominantly made the decisions and the female farmers followed. Through the
88
integrated community development activities and with close collaboration from the existing
Women Union system, VLCRP had built up the knowledge and capacity for more than 1,200
women including single women-head of households for adopting the advanced farming
technique, gender equity in agriculture production and household economic management. As
a result, women were able to better track records of crop inputs and farm labor used; and
reported they are being consulted more for farm planning in their households. On average,
women-headed households saved 2 million dong (90 USD) of input cost per hectare,
increasing their net profit by 1.6 million dong (about 80 USD) per hectare and had their yield
increased by 1.35 tons/ha.
Mrs Tran Thi Dao, Head of Women’s Union of K7A hamlet said: After learning the 1M6Rs, I
now understand that the rice does not always required water and that the alternate wet dry
scheme helps the rice to grow better while reducing the greenhouse gas emissions. In the
summer-fall crop of 2014, I will convince my husband to use less seed and fertilizer and apply
the AWD. Of course I will also advocate and convince other women to apply 1M6R.
A full gender aggregated database with measured progress from women participation to
VLCRP community development activities and application of 1M6R was created, analyzed
and disseminated to relevant audience including local authorities, Women’s Union, DARD,
Extension Centre and community leaders to strengthen women’s roles in adopting the
contemporary farming techniques and their roles in their communities. Specific results from
women livelihood improvement can be referenced from the case study of Mrs Nguyen Thi
Ngoc Huong, a single woman-head of household in K7b Coop, Tan Hiep district of Kien
Giang province (attached).
4. Lesson learned: major challenges and solutions
The low carbon rice farming protocol requires certain infrastructure conditions, operational
and management mechanisms and agricultural policies to ensure that the large scale rice
production that results from small households can apply consistent crop management
practices in order to generate and optimize the economic, social and environmental benefits.
After a total 11 crops in An Giang and Kien Giang, the following major challenges were faced
and addressed by VLCRP.
4.1. Challenges from the Farmers and their Community
o Farmers often worry about losing their yield and income when the 1M6R protocol
reduced seeds, and fertilizer and implemented alternate wet dry water management.
o There are conflicts between husband’s and wife’s for changing from conventional to
1M6R farming practices
o There are a lack of “farmer leaders” who can be peer educators to their communities
o Few households disagree with the community’s crop plan
o Farmers are dependent on the private suppliers’ credit and thus dependent on the
recommended quantity
o Farmers often have to use credit to purchase their materials at the local shop. Thus
they must purchase whatever materials are available and often, the quality of those
materials were not of high quality.
4.2. Challenges from external conditions
89
o Adverse weather: prolonged heat, strong rain, whirlwinds, storms, and floods occurred
in most of the crops and during the key development stages of the rice or just before
the harvest.
o Lack of access to quality materials (seeds, fertilizer, pesticide)
o Ineffective irrigation infrastructure
o Uneven topography of the paddies
To address these fundamental challenges, VLCRP collaborated with relevant partners and
local authorities to execute the technical solutions and management mechanism as following:
1. Designed and maintained the “demonstration paddies” in the area of each Production
Group to allow farmers’ observation and evaluation. Farmer Field School and Group
Meetings are used to raise awareness and capacity of farmers for adopting the 1M6R
farming protocol.
2. The 1M6R protocol is specifically designed for each cropping season to ensure its
suitability with the specific cropping features, irrigation system, water irrigation
procedures, capacity of the extension workers and the ability of farmers for adoption.
3. Organized and trained the field-based extension team for supporting each of the
Production Groups in terms of crop management (fertilizer application, water
management, pest management, farmer’s Diaries updates). The Group Leaders and
advanced farmers lead the community to follow their best practices.
4. DARD and local authorities provided relevant technical support and matching funds
for paddy management, infrastructure improvements including irrigation system and
paddy topography leveling by laser equipment.
5. Last but not least, the direct management and execution from DARD and their
Extension Centers play key roles in transferring direct technical support to farmers
during the entire crop, from selection of high quality seeds, fertilizer to market linkage
support, creation of relevant policy support and coordination of support from technical
agencies (irrigation, plant protection, local authorities). The DARD of An Giang and
Kien Giang also mobilized and provided matching funds and relevant development
projects to generate synergies and build storage facilities and laser equipment for land
leveling.
5. Conclusions and recommendations
1. The low carbon rice farming protocol has proven itself as an advanced technique that
has delivered multi-benefits in terms of economic development, poverty reduction for
rural farmers and environmental protection including the reduction of greenhouse gas
emissions and soil and water pollution in the Mekong Delta which contribute
effectively to the realization of the Agriculture Restructuring Plan of Vietnam. An
Giang and Kien Giang provinces have long been the two top advanced and productive
rice production provinces; however the application of 1M6R has increased their yield
and profitability from 5-60%. Hypothetically, if the 1M6R tehcniques are applied
across the 1.85 million ha of rice in the MD, the cost savings for materials is 7,400
billion dong (equivalent to 352.3 million USD) annually and the water saved is
approximately 2.4 billion m3. As such, the facilitation and promotion of adoption of the
1M6R in the large scale rice production model for improving the quality and
comparative advantages for the rice is recommended.
90
2. VLCRP’s research data showed the close relationships between the economic and
environmental co-benefits versus the crop management practices, water irrigation and
ecological zones. For the 1M6R to optimize its efficacy, the replication and research
activities should continue in the five remaining ecological zones and geographical areas
of intensive rice cultivation in the MD.
3. The continuation of experience sharing and learning with other low carbon
rice/agriculture projects is a pivotal activity to standardize and document the optimum
low carbon rice farming protocol for widescale adoption.
4. Research and hands-on field experience on low carbon rice farming at the community
level should be used for evidence-based rice production planning at the provincial level
and policy recommendations at national level. At the community level, policy
recommendations should be focused on the modality and mechanism to support the
improvement of the rice value chain and the engagement for a win-win partnership
among farmers, scientist, government and private sector. At the national level, as the
VLCRP policy dialogues are being undertaken, policy recommendations should be
proposed for enhancing the effective coordination among the 3 key technical agencies
of Crop Production, Plant Protection and Water Resources Irrigation Department for
supporting the low carbon agriculture practices from the grass-root level and up. These
policy changes will support and accelerate the process of realization of the Rice
Restructuring Plan in particular; and the overall economic and social development in
general.
5. The low carbon rice farming protocol proves its feasibilities in promoting women’s
capacity and capability in adopting and mastering the contemporary advanced farming
technique as an innovative livelihood improvement for women. Further investigations
and interventions for gender empowerment in modern agriculture activities should be
continued at community and provincial level to facilitate the Women Union’s roles and
responsibilities in gender-focused livelihood improvements.
The restructuring of Agriculture toward modernization, increasing the competative
advantages and profitability in agriculture in an environmental-friendly style has been one of
the top priorities in the social economic development strategy of the Government of Vietnam.
The low carbon rice farming is an advanced contemporary farming technique has been
developed and applied in large scale of over 530 ha/each crop by VLCRP and their partners in
An Giang and Kien Giang provinces. The application and wide-adoption of 1M6R farming
protocol has delivered meaningful outcomes for economic, social and environment
development that are aligned with the development priorities of the agriculture sector and
Vietnam as a whole.

Annex 2: Case study of Mrs Nguyen Thi Ngoc Huong
Prior to the launch of VLCRP in Kenh 7b ward,
Thanh Dong A commune, Tan Hiep district of Kien
Giang province, rice farmers harvested two crops of
rice per year. On average the net income per hectare
from rice cultivation was about 14.5 million
VND/hectare. During times when the crop was not
productive, farmers were not able to pay for their
input costs. A widow since 2008 and nursing five
children, Mrs. Nguyen Thi Ngoc Huong’s main
income source is from Rice production. Mrs. Huong
has participated in the VLCRP project since
November 2012 and practiced VLCRP’s farming
model, 1 Must 6 Reductions, over her three hectares
of land. To date, six crops have been harvested. A full
data set of farming practices of Mrs. Huong’s family
prior to joining VLCRP project and during the last 6
crops is available in VLCRP’s Baseline study and
Crop Evaluation database and shown below.
In 2012, I was encouraged to join the Vietnam Low Carbon Rice Project. At first and
during the entire crop one (the Winter-Spring crop 2012-2013), I was very nervous
because the project’s farming technique reduced 50% of the seeds, 30% of fertilizer,
reduced the water and minimize the herbicide spray as much as possible. During the
crop, I was trained to count the panicles and tillers, and witnessed that even if I used
much less seeds and fertilizer, the total rice panicles and tillers in my paddy are about
the same but even stronger than the paddies with much higher seed density and
fertilizer application. The results of the first crop were very positive. Thus I have been
practicing 1M6Rs since that. The last Winter-Spring crop of 2013-2014, with three
hectares of land for rice cultivation, our family earned more than 100 million Dong
after subtracting the input costs. I am no longer nervous when following the project’s
farming technique; and am very happy now that I can pay back my debt, cover the
living cost and pay for tuition fees for my sons and my daughters. Joining this project,
I learned a lot from the regular community meetings and the on-farm support from
our Group Leaders, Extension Workers and Teachers from Can Tho University. Our
lives are a lot easier and happier. I am also joining the Women Union’s regular
meetings in my commune, and I shared with many other women about the 1M6Rs
farming practices to help them to increase their family income.

Abstract
The “Vietnam low carbon rice project - VLCRP" has been implemented at Kenh 7B cooperative, Tân Hiep, Kien Giang province and Phu Thuong cooperative, Phu Tan, An Giang province for improving rice cultivation of 1 Must – 5 Reductions model (1M – 5R) to 1 Must 6 Reductions model that resulting higher households’ income and green products – low carbon emission. The experiment had been carried out since the winter-spring crop 12–13 until autumn-winter crop 2014 with 3 models: 1) 1 Must 6 Reductions, 1M6R+Tricoderma (TRI) and traditional practice as Control (CON). The results from 11 rice crops show that application of 1P6G+AWD could reduce 47% of seed rate; 24% of nitrogen, 32% of pesticide application; 48% of water for production; 30% of losses during production and increase about 12% of average rice yield and 50% of profit in comparing to CON model. The results indicate that the model of 1P6G-AWD benefits higher economic efficiency, improving environment conditions; and it is also a potential technical model for poverty alleviation for poor farm households towards green agriculture in the Mekong Delta.
Keywords: 1 must – 6 reductions, alternative wetting and drying, yield, economic efficiency, rice
1. Introduction
Rice is the main food crop of almost all Asian countries and around the world; thus, rice is
cultivated with a large area. The estimation of the amount of water used in rice cultivation is
about2,700 billion m3/year of the total amount of water used globallyof about 3.800 billion
m3/year(Pham Thi Thanh Hoa, 2013). In the context of global climate change such asdrought,
floods, saltwater intrusion, etc., the efficiency of water management in agricultural production
is a major concern of agricultural countries, especially the Mekong Delta, Vietnam.
Many research have proven that there is an emission of methane (CH4) during the period of
rice cultivation; this gas is one of the major gases directly affecting to the global warming.The
practices of continuous wetting, high seed rate, too much fertilizer (nitrogen), etc.have been
the main cause of greenhouse gases emission (GHG). The emission in Vietnam is 150.9 Tg
CO2 (1 Tg = 1 million tons); in which, the GHG emission of agriculture sector is 65.09 Tg
CO2accounting for 43.1% of the total GHG emission of the country. In the agriculture sector,
wet rice cultivation accounts for 57.5% the GHG emission of whole sector(VSC, 2010).

The reduction of water for irrigation (drained out) few times during a rice crop could decrease
about 50% of methane emission (Khosa et al., 2011; Elena Sanchis et al., 2012). In order to
save water and reduce GHG emission in rice production along with improving farm
household’s income, many new advanced practices which could reduce production costs and
increase rice yield such as 3 reductions – 3 gains (Heong et al., 2010); 1 must 5 reductions
(Truong Thi Ngoc Chi et al., 2013), System of rice intensification – SRI (WWF-ICRISAT,
2010), and 1 must 6 reductions (1M6R) - “1M5R” integrating with alternative wetting and
drying method (Huynh Quang Tin, 2014) are introduced in Vietnam. However, many farm
households are not applying the model of 1M5Rimproperly causing low production efficiency
and low income (Nguyen Ngoc Son et al., 2013).Thus, the pilot of VLCRP aims to
standardize farming practice and determines the impacts of alternative wetting and drying
technique to rice yield and economic efficiency in rice production at Phu Thuong, An Giang
andKenh 7B, Kien Giang from 11/2012-12/2014 providing a reference for recommendations
in production in the Mekong Delta, Vietnam.

2.2.2. Practices
Land preparation: after harvesting, the rice field was turned up and fallowed around 1-2 weeks, then harrowed and leveled for sowing. For the model using rice straw,
Trichoderma was buried down 2 weeks before sowing preventing poisoned.
Fertilizer application: Amount and timing for fertilizer application in all models was arranged at the same time for all sites, as following:
99
Table 2.3: Amount and timing of fertilizer application for research models at K7B and PT
1M6R-AWD N (%) P (%) K (%)
1 (8-10DAS) 20 50 0
2 (20-21 DAS) 40 50 0
3 (40-45DAS) 30 0 50
4 (70-75DAS) 10 0 50

2 (20-22DAS) 40 50 0
3 (40-45DAS) 29 0 50
4 (70-75DAS) 10 0 50
Water management:
o The process of 1M6R-AWD was stimulated and applied as shown in the figure
below, timing for controlling water level in the rice field was recommended
accordingly to period before fertilizer application and at the end of tillering
stage to decimate the non-productive tillers and easy for harvesting.
o The CON model was applied the traditional practice of the areas. The water
level in this model is followed the schedule of irrigation group and cooperative
which included drain-out twice (at the mid-season and 10 days before
harvesting).
The process of AWD was designed for the 2 project areas as following:
Figure 2.1a: Water management in research models at Kenh 7B
100
Figure 2.1b: Water management in research models at Phu Thuong
2.2.3. Data collection on agronomic characteristics
The variables of height, tiller development, lodging, growth duration, panicle and rice yield
were monitored periodically and followed the growth stages of the rice plant based on the
Standard Evaluation System for Rice (IRRI, 1988).
Rice roots:
Rice roots were randomly collected 10 rice plant/field in different times of 14, 21, 28, 35, 42,
56, 6 DAS for evaluating the development of rice roots in each treatment. The rice roots were
cleaned up and measured for average after dis-rooting.
Stem – internodes:
Internodes diameter: 10 days before harvest, 20 – 30 rice plants were randomly selected in
each field, main stem of each bush was picked for measurement as follow:
o Internodes length: the 3rd
, 4th
and 5th
internodes (from top goes down) were selected
for measuring the length (from 2nd ends of each internodes) and average length of
each internodes.
o Internodes diameter: the 3rd
, 4th
and 5th
internodes were selected for measuring
diameter at the middle point of each internodes using technical tool and calculating the
average.
o Thickness of internodes: Cutting at the central part of each internodes 3, 4, 5; using
technical tools to measure thickness in mm and calculate average thickness.
2.2.4. Yield components
Panicles/m2: counting the number of panicles of 3 frames on each field. The total
panicles of 3 frames (50 cm x 50 cm = 0.25 m2) was calculated into panicle/m
2.
Full grains/panicle: randomly seelcting 10 panicles for counting the total full grains
and unfilled grains. The average full grains/panicle was calculatedfor each frame.
Weight of 1,000 grains: selecting 1,000 full grains of each frame and weighting using
electric scale. The results of weight (g) and moisture (14%) were recorded.
101
Actual yield: The grain was harvested from 3 distinct frames, 10m2/frame, and then
the threshing was carried out. Cleaning, weighing and measuring moisture content
were recorded.
All of the data related to grain weight were measured with the standard moisture of
14% applying the follow formula:
Wo x (100-Ho)
Weight (14%) = ------------------
86
In which: Wo: weight of grains (harvesting 5 frames or 10m2)
Ho: moisture content when weighting (%)
Rice yield calculation: Yield (ton/ha) was calculated by the weight of average weight of
frames (10m2).
2.2.5. Economic efficiency
Each project farmer was provided a "household note" and be trained to record the cost of
production including costs of materials, fertilizer, fuel materials and equipments, the cost of
hiring labor and services and analyzing production efficiency of each model. Economic
efficiency was calculated as follow:
Total cost (1 ha) = materials + labors
o Material costs
o Labor cost = hired labors + household’s labors
Total income (ha) = Yield (kg) x Selling price (VND/kg)
Profit /1 ha = Total income – Total cost
2.2.6. Data analysis
The data was input by using Microsoft Excel and analysed by using the SPSS software with the
T-test tool for study the difference of average between models in term of agronomic
characteristics, yield,costs, profit and net profit.
3. Results
The study on agronomic characteristics and economic efficiency was conducted at Kenh 7B
and Phu Thuong through 11 rice crops with positive results which could prove the advantages
of 1M6R-AWD model as following:
3.1. Impact of water management on rice growth
Growth duration:
At Kenh 7B: Jasmine variety was used during winter-spring crop and OM5451 variety was
used in the remaining rice crops. Figure 2.2 shows that the growth duration of rice in 1M6R-
AWD model is 1-3 days longer than those in CON model.
At Phu Thuong: CK92 variety was used in 3 rice crops from WS12-13 to AW2013 and
CK2003 variety was used in the last 2 rice crops. The results show a change in growth
duration throughout seasons, the duration in WS crop was longer than AW crop. During
102
WS13-14, due to cold weather condition, the growth duration was prolonged up to 7 days.
The model of 1M6R-AWD had a longer duration than CON model from 1-2 days.
Figure 2.2: Growth cycle (days) of rice varieties through 11 rice crops at K7B and PT
Height:
This characteristic is affected by cultivation conditions, in which water management is
one of the important factors. During the period of water drained-out, the rice height
was developed slowly and those in 1M6R-AWD model seem to be lower than those in
the CON model (Figure 2.3). This result is confirmed by the research of Tuonget al.
(2005), when water is drained-out, the rice roots develop deeper into the soil searching
for water; however, due to high rain fall in AW crop and appropriate water
management, there is no significant different between the 2 models.
Length of panicle:
The length of panicle (Table 2.4) in the model of 1M6R-AWD is always longer than
those in the CON model about 2cm and this is significantly different. The result could
be due to low sowing rate and appropriate fertilizer application and water management
of 1M6R-AWD model, the rice plants could develop a longer root system contributing
to better nutrient absorption, bigger panicles and increasing in length resulting higher
yield.
Figure 2.3: Plant height average of rice
plant throughout 11 crops at K7B and PT
Figure 2.4: Length of panicle between 2
models throughout 11 crops at K7B and PT
Development of tillers
The weekly data shows that the maximum number of tillers was reached at 21-28 DAS
in WS crop and SA crop; and 28-35 DAS in AW crop. With a high sowing rate, the
103
maximum number of tillers of CON model is always higher with low productive tillers
(50-60%) as compared to 1M6R-AWD model.
Internodes:
Figure 2.5 shows that the characteristic of the 4th
internodes is significantly different
between the two models. Water drained-out resulted shorter internodes with bigger
internodes diameter and higher thickness in 1M6R-AWD model comparing to CON
model. These traits contribute to a strong stem for rice plants lowering lodging rate
comparing to CON model; and this result is also corresponded to the study of Vu Anh
Phap (2013).
Figure 2.5: Averaged length, diameter and thickness of 4th
internodes in the experiments at
K7B and PT
Note: characteristic of 4th
internodes of 1M6R is significantly different with CON at 1%
3.2. Yield components and rice yield
Figure 2.6 shows that averagenumber of panicle/m2in1M6R-AWD model is less than CON
model of about 100 panicles/m2 and is significantly different with CON model at Kenh 7B
and Phu Thuong. The reason for this difference is the high sowing rate of CON model.
Number of panicle/m2in 1M6R-AWD model is low, but the length of panicle is longer and
number of full grains/panicle is higher (12 grains/panicle) significantly comparing to CON
model. The significant difference in number of full grains/panicle contributes to higher yield
of 1M6R-AWD model. The results indicate that low sowing rate with appropriate fertilizer
application contribute to less pest/diseases, stronger stem and high ratio of full grains.
The weight of rice/sticky rice grain in the experiments is note significantly different between
the models due to the characteristics of the varieties. Thus, grain weight is not an important
factor contributing to higher yield in the experimental models.
104
Figure 2.6: Panicles/m2 and fulfilled grains/panicle of models by 11 crops at K7B and PT
Rice yield(Figure 2.7) is high during WS crop and reaches the lowest number during AW
crop. The model of 1M6R-AWDalways has a higher yield about 11% and is significantly
different to CON model. During the 3 experiment crops (WS12-13 to SA 2013), 1M6R-
AWD+TRI model had reached the rice yield equivalent to 1M6R-AWD model and higher
than CON model about 0.5 ton/ha comparing to CON at K7B and PT.

3.3. The efficiency of 1M-6R model
The situation of pest/diseases and application of plant protection chemicals: The situation was
happened unfavorable for the experimental models at Kenh 7B and Phu Thuong. Brown plant
hopper, rice leaf folder and blast leaf, viruses happened several times every rice crop with
different level of damages and farmers applied chemicals to solve the problem. In general,
farmers applied chemicals about 3 – 4 times in 1M6R-AWD model and less than CON model
(Figure 2.8).
Application of “alternative wetting and drying” technique: the data shows that the amount
water used in 1M6R-AWD model was significantly decreased – average of 1,296 m3 (43%) at
Kenh 7B and 3,518 m3 (48%) at Phu Thuong. Application of AWD has greatly reduced the
amount of water used (Figure 2.9) with no decreasing in rice yield. This result indicates that
1M6R-AWD model will be a potential model for rice production in the future to cope with
water scarcity.
Figure 2.8: Average of chemical application
times in each rice crop at K7B and PT
Figure 2.9: Average of amount of water used
per rice crop at Kenh 7B and Phu Thuong
Economic efficiency analysis between 1M6R+AWD andCONmodel (Table2.4) shows a
decreasing of seed rate by47%; fertilizer by24-28% (nitrogen and phosphate), chemical
application by32%; losses during harvesting by 31%, and saving water about 45% of water
comparing to CON model. The result indicates that 1M6R+AWD model brings higher
economic benefits and environment friendly.

3.4. Economic efficiency
Investment costs (5 Reductions)
In all experimental models (Figure 2.10), input costs of CON model include seed, fertilizer
and chemicals accounting for a high proportion (44%) of total costs;
Application of “1M6R-AWD”:farm households could reduce the costs of seed, fertilizer,
chemicals with the average of about 9.7 million VND/ha (37%) comparing to CON model.
Comparing of investment costs between 2 project sites shows that the production costs of
households (1M6R-AWD and CON) at Phu Thuong is higher about 3-10 million VND/ha
than those at Kenh 7B.
The cost of irrigation and harvesting are similar in each project site because the existing
management mechanism requests all farmers to share equally the total pumping cost to their
Co-ops; thus there is no difference in cost reductions between models.
Figure 2.10: Production costs of 1P6R-AWD and CON through 11 crops at Kenh 7B and PT
Financial efficiency
The average data of 6 rice crops at Kenh 7B – Kien Giang and 5 rice crops at Phu Thuong –
AG (Figure 2.11) show that the total investment in CON model is higher about 19% (KG) and
37% (AG) comparing to 1M6R-AWD; however, the total income and profit at Phu Thuong,
AG is higher than those at Kenh 7B.
There is not significant difference in average profit between 1M6R-AWD and 1M6R-
AWD+TRI at K7B and PT. However, 1M6R-AWD model earns higher profit about 7 - 8
million VND/ha at Kenh 7B and Phu Thuong comparing to CON model. The higher profit of
1M6R+AWD model is due to: 1) reducing cost of seeds, fertilizer and chemicals, and 2)
higher rice yield of 11.5% contributing to higher profit.
The profit of 1M6R-AWD model at Phu Thuong is higher than Kenh 7B due to higher selling
price of sticky rice (Phu Thuong) than paddy rice (Kenh 7B) during the first 3 rice crops of
the project. In addition, there is occasion of rain at the harvest time of AW cropat Kenh 7B
affecting to selling price and profit of the models.

Figure 2.11: Returns form models throughout 11 rice crops at Kenh 7B and Phu Thuong
In general, 1M6R+AWD and 1M6R-TRI model earn higher financial efficiency significantly
in statistical analysisto CON model. The profit is stable at Kenh 7B with 20 million
VND/ha/rice crop; especially, the 4th
rice crop (WS13-14),the highest profit was reached with
45 million VND/ha due to high rice yield and high selling price.
At Phu Thuong (AG), the profit has gradually reduced since the beginning of the project due
to the fluctuation of paddy rice and sticky rice selling price on the market, the highest profit
were achieved in the 1st and 2
nd rice crop with about 37 million VND/ha.

During the implementation of experiment and developing of 1M6R-AWD model,
many occasions of pests/diseases had happened directly affecting to the rice growth
and development such as brown plant-hopper, rice leaf folder,stem borer; blast
disease, bacteria diseases. Infection of pests/diseases contributed to higher production
costs of households; however, those applied 1M6R model could reduce 2 chemical
108
application/rice crop which reduced production costs and contributed to the
improvement of environment.
Weather conditions
- During the last 2 years, all of experiments have been affected by unfavorable weather
conditions causing difficulties from sowing until harvesting.
- In SA 2013 crop, high rainfall and strong winds happening during the harvest times
caused high damage to all the project sites at Kenh 7B. In addition, occasion of rain
happened during sowing time causing flood and low productive of rice plant
contributing to higher production cost for re-sowing and transplanting.
- On the other hand, high rainfall also affected greatly to the water management at Kenh
7B and Phu Thuong (Figure 2.12), especially during SA and AW crop there was high
probability of rainy days and high rainfall. Thus, period of water control could not be
done properly according to the process and sometimes needed to drain-out (AW crop).
Figure 2.12: Rainfall regime affecting to water management at Kenh 7B and PT, SA2014
- Although affected by unfavorable weather conditions, the project farmers have applied
the process quite well crop by crop resulting the decreasing of water pumping about 2-
3 times in the 1M6R model and the water level in the rice field is also lower and
saving of about 45% of water comparing to CON model.
Infrastructure for water management:
There is a dyke system and irrigation system in the project area which could provide enough
water even during the AW rice crop (Phu Thuong). However, at Kenh 7B, there is usually
rainy days during the AW crop which causes difficulty for water controlling. Although the
process of 1M6R shows high economic efficiency, there are difficulties in wide spreading the
process to other farm households in the project areas:
109
- At Phu Thuong: Farmers have to follow the schedule of irrigation of “1 time
pumping/every 10 days” agreed by members of the cooperative; thus, the water
control of participated households sometimes could not be managed in full accordance
with the recommended process.
- At Kenh 7B: The water management is totally dependent on the water pumping sub-
stations and the mechanism of cooperation between groups in term of timing (due to
differences in investment: water pumping station and pumper) and cost. Although
there are advantages in the system, it also affects the unification in water management.
Moreover, due to the dimension of the rice field, it requires time to level the water in
the field causing unequal flooded plot in the field.
Techniques
- The combined technique of using rice straw with Trichoderma could increase the soil
fertile and reduce fertilizer application in rice production. However, it requires time
for rice straw to be decomposed ensuring low emission of CH4.
- During the autumn-winter rice crop, there are high probability of rainy days and high
rainfall causing flood in the rice field. These conditions limited the development and
growth of rice plant causing low productivity and rice yield. Other techniques such as
fertilizer formula, timing for fertilizer application and sowing rate should have been
further studied in order to help farm households improving their households’ income.
4. Conclusions and recommendations
4.1. Conclusions
Based on the collected agronomic data and production costs of 11 experimental rice crops for
the model of 1M6R-AWD at Kenh 7B and Phu Thuong, the following conclusions are made:
The model of 1M6R-AWD including several water control periods had contributed to a
shorter rice stem – stronger stem, bigger internodes – more thickness of internodes and
longer panicles (1cm) comparing to CON model.
The number of full grains/panicle in the model of 1M6R-AWD is higher about 12 grains/panicle (31%) and is also an important factor resulting higher rice yield and is
significantly different to CON model.
The application of 1M6R-AWD model has reduced 47% of seeds, 24% of nitrogen fertilizer, 48% of water, 32% of chemical applications comparing to CON model.
The average rice yield of 11 rice crop of 1M6R-AWD model is higher about 11.5% and
50% of higher profit than traditional practices.
The model of 1M6R-AWD is effective and suitable for wide application in rice production inKien Giangand An Giang province. 1M6R-AWD model is a potentially technical model
for increasing rice yield and product value and green agriculture.
4.2.Recommendations
With the positive results from 11 experimental rice crops, 1M6R model is very potential for
wide introduction and application; however, the following recommendations are made for
better results of application:
- Continue to standardize the technical process of 1M6R model and alternative wetting
and drying for different ecological systems in the Mekong Delta.
110
- Further study is required for better understanding the relationship between the ratio of
rice straw and emission in order to make suggestions for wide adaptation contributing
to the development of sustainable and green agriculture.
- Further study about fertilizer formula, timing of fertilizer application and appropriate
cultivation technique are required in order to increase rice yield and profit during the
autumn-winter rice crop.
- Selecting and better support for core farmers are needed in order to demonstrate the
technique, transfer and widespread the model of 1M6R to farmers in the Mekong
Delta.

STUDY ON CULTURAL PRACTICES
FOR INCREASING INCOME OF AUTUMN-WINTER RICE CROP
IN TAN HIEP, KIEN GIANG PROVINCE
Huynh Quang Tin1, Nguyen Van Nhat1, Nguyen Cong Uan2, Tran Thu Ha3
Abstract
The study on technical intervention for increasing income during autumn-winter rice crop inTan HiepKien Giangprovince was conducted with 03 treatments: (1) sowing rate, (2) nitrogen fertilizer formula, and (3) timing of fertilizer application. The experiment was arranged with 3 repetitions and the data of rice yield andproduction costs were collected for analysis to find out the differences between the treatments. The results show that: high profit could be achieved with the sowing rate of 80-120 kg/ha; the treatment of applying no fertilizer had the rice yield which was not different to the treatment of nitrogen fertilizer formula of 80-35-45kg/ha and achieved equal profit with CON model; 1 time of fertilizer application (8 DAS or 40 DAS) could achieve high economic efficiency but was not significantly different to none fertilizer application and CON; applying appropriate technical interventions could earn high economic efficiency with the sowing rate of 120kg/ha andapplying no fertilizer. The autumn-winter rice crop atKenh 7B, Thanh Dong A, Tan Hiep,Kien Giangprovince with the application of none-fertilizer treatment could be a model for green rice production with high income. However, further study is required for the autumn-winter rice cop 2015 in order to confirm the result for recommendation into production.
Keywords: yield, economic efficiency, fertilizer application, sowing rate, rice
1. Introduction
There is an increasing trend of rice production during the 3rd
(autumn-winter) rice crop in the
Mekong Delta around 832,000ha (CTT, 2015) in order to ensure the national productivity and
create job for farmers. However, during the AW crop, there is high probability to encounter
unfavorable weather conditions and is difficult to apply technical interventions causing lower
profit than SA rice crop about 17-19% with similar inputs and selling price (Pham Le Thong
et al., 2010). Currently, rice production during AW crop is usually affected by unfavorable
conditions causing low rice yield (less than 5 tan/ha) (Nguyen Ngoc Son et al., 2013). Based
on the surveyed and practical data of AW rice crop ofVLCRP at Thanh Dong A commune,
Tan Hiep, Kien Giang province, it shows that the rice crop completely happens during the wet
season (July – October). This reason has significant impacts on sowing, water control and
efficiency of fertilizer application which has causedhigh production costs, low rice yield
(about 4 ton/ha), and low profit or loss.
Beside from creating jobs for farmers, increasing income and rice productivity, 3 rice crops
production also cause low nutrient contents in the soil, low rate of organic matters and
reducing rice yield (Tan et al., 1995; Tan, 1997; Lai et al., 1997; Hoa et al., 1998; Phung et
al., 1998; quoted by Huynh Dao Nguyen, 2008). In order to find out the appropriate
intervention for farmers to improve their households’ income, the experiment of technical

interventions during the AW rice crop was conducted during the AW crop 2014 at Tan Hiep,
Kien Giang province.
2. Materials&methodology
In order to achieve good result for analyzing major factors and comparison of profit, 3 distinct
experiments had been conducted from 7-10/2014 at Thanh Dong A commune, Tan Hiep, Kien
Giang province. The materials and experiment establishment are listed below:
2.1. Materials
OM5451 variety was used for experiment; the fertilizers were the same for all experiments;
plastic canvas, and other necessary tools for experiments.
2.2.Experiment establishment
Experiment on sowing rates:
Five treatments (80, 120, 160, 200 và 240 kg/ha) were laid out in the randomly complete
design with three replications. Area of each plot was 100 m2. Fertilizer formula was 65N-
35P2O5-45K2O kg/ha.
Experiment on nitrogen fertilizer formula:
The experiment included 06 treatments arranged completely random block with 03 repetitions
(76 m2/ replication).In which, the CON treatment was applied no fertilizer andtreatment 6 was
applied traditional practice (90-70-70). The other treatments were set a fix amount of
phosphate (P) andpotassium (K) as 35% K2O and 45% P2O5;the amount of nitrogen fertilizer
in experiments were 30%, 45%, 65% and 80%. The sowing rate for broadcasting method was
120 kg/ha. The timing for fertilizer application was: 1st timeat 08 DAS (32% nitrogen and
50% phosphate); 2nd
timeat 20 DAS (28% nitrogen, 50% phosphate and 34% potassium)
and3rd
timeat 40 DAS (40% nitrogen and 66% potassium).
Experiment on the timing for fertilizer application:
The experiment included 07 treatments of 08-20-00; 00-00-40; 08-00-40; 00-20-40; 08-00-00;
08-20-40 (Đ/C) and 00-00-00 arranged randomly, with 03 repetitions(50 m2/repetition).The
sowing rate was 120 kg/ha. The based fertilizer formula was 65-35-45. There were 03 fixed
period of fertilizer application as1st time: 08 DAS (32% nitrogen and 50% phosphate); 2
nd
time: 20 DAS (28% nitrogen, 50% phosphate and 34% potassium) and3rd
time: 40 DAS (40%
nitrogen and 66% potassium). The total amount fertilizer was different between the
treatments.
2.3.Data collection
Rice yield: The rice yield was applied accordingly to the Standard Evaluation System for Rice
(IRRI, 2014)
Production costs: Each household which participated in the study was provided a “Household
note” and was trained to record details from sowing to harvest such as: input costs, fertilizer,
fuel and equipments, labor and calculating economic efficiency at the end of the crop for each
model.
2.4.Data analysis
Analysis of variance (ANOVA) with DUNCAN test was applied to find out the difference of
rice yield and economic efficiency between treatments of each experiment.
113
3. Results
3.1. Water management
During the AW crop 2014, there were 45 days of rain with the total rainfall of 832mm.
Raining in the sowing period had affected the experimental field (seeds were engulfed deep
into the soil) and slow growth of rice seed during the first week.
In the AW crop 2014, there was only 1 period of completely drained out the water (33-
42DAS) overlapping the period of no rainfall. However, rainfall caused great impacts on the
water control during the period of 0-30 DAS affecting the field in continuous flooding which
required pumping-out at 20-25 DAS for 2nd
time of fertilizer application. During the period
from the 3rd
time of fertilizer application (40 DAS) to harvest, the water level in the rice field
was around 5-20cm; especially, rainfall happened during flowering stage directly affecting the
rice yield. The water level was high during the period from flowering stage to ripening stage
due to seasonal flood. In general, the water control process could not be done properly during
the AW rice crop.
Figure3.1: Rainfall and water management in the experiments,AW 2014atKenh 7B
3.2. Results on rice yield
Experiment on sowing rates
There was only 1 time of water control (completely drained out) in the mid-season causing
flooding in the experimental treatments and affecting the development of tillers. Figure3.2
114
shows that the rice yields of the sowing rate of 80-120kg/ha was highest and is significantly
different to other treatments. According to farmers, high sowing rate could not achieve a good
development of tillers as of low sowing rateand the similar situation happens to the number of
grain/panicle; thus, the number of full grains/panicle in low sowing rate is the important factor
contributing to the increasing in rice yield.
Figure3.2: Rice yield in the experiments on sowing rateat Kenh 7B, AW-2014
Note: On top of each column, similar letter means nto significant different; T-value and * mean
significant different at 5%.
Experiment on nitrogen fertilizer formula
Figure3.3 indicates that high rice yield could be achieved with high amount of fertilizer and
continuous flooding method; however, it would cause high production costs and high lodging
rate in treatment 5 and 6. The actual rice yield is gradually increasing and is directly
proportional to the amount of nitrogen fertilizer used. However, only the CON treatment (90-
70-70) achieved high rice yield and was significantly different at 5% comparing to the rest.
In the treatment of none application of fertilizer,the rice leaf is quite shorter and light yellow
in color but the stem is strong and less infected by pest/diseases and the yield of the treatment
was 4.2t/ha and was not significantly different to other treatments (up to 80-34-45kg/ha). The results indicate that the capacity of nutrient absorption of rice plant was low due to high level
of water in the rice field; thus, intensive fertilizer application during AW crop is not an
appropriate technique for sustainable increasing of rice yield.

Note: On top of each column, similar letter means nto significant different; T-value and * mean
significant different at 5%.
Experiment on the timing for fertilizer application
Applying similar water control method with the reduction in fertilizer amount and time pf
application, the result shows that the rice yield is increasing accordingly to the increasing in
the amount of nitrogen fertilizer used(Figure3.4). The highest amount of fertilizer used was of
CON treatment (65-35-45) with 3 applications achieving highest yield (4.6t/ha) and was
significantly different to other treatments.
There are some similarities to experiment on nitrogen fertilizer formula; however, in
treatment 2 and 3, there was only one time fertilizer application with a great reduction in the
amount and it could achieve quite high rice yield with no significant difference to CON. This
result indicates that treatment 2 and 3 could reduce production costs and pollution in
comparing to CON (treatment 7).
In the treatment of none fertilizer application, although the rice plant grew weakly, the rice
stem was strong and low lodging rate and low rice yield with no significant difference to
treatments with 1 to 2 applications (excluding CON). This will be compared in the section of
economic efficiency; however, the rice yield of 3.8t/ha is acceptable for green rice production
with great impacts to environment and no losses.

4.3 Economic efficiency
Experiment on sowing rates
Table3.1 shows that high sowing rate caused high production cost in CON treatment (240
kg/ha) which is higher about 1.2 timethan the treatment of 80 kg/ha and is significantly
different to other treatments.
116
Income and profit of the treatment of 80-120 kg/ha is highand significantly different to other
high sowing rates. The profit of the sowing rate of 80 kg/ha is higher than the sowing rate of
240 kg/ha (CON) about 5.57 million VND/ha (increasing 42%). The treatment of 80kg/ha
also has the highest profit ratio of 1.9.

Experiment on nitrogen fertilizer formulas
The higher amount of nitrogen fertilizer is used, the higher income is earned;however, income
between treatments was not much different, only the treatment of 90-70-70 is significantly
different to no-fertilizer treatment. Treatments which were applied much nitrogen fertilizer
had higher production costs causing many impacts such as water pollution, high labor cost,
health, etc.
Interestingly, although the production cost was high, the profit per area unit was not
significantly different in all fertilizer formula including none fertilizer application
treatment(Table3.2). The results show that the treatment of none fertilizer application and
high amount of nitrogen (CON) could earn higher economic efficiency than other treatments.
The reason could be due to the characteristic of AW rice crop which are intensive application
of fertilizer (because of low capacity of nutrient absorption of rice plant during this period) or
great reduction of fertilizer application. In other treatments, although the production cost was
low, the low capacity of nutrient absorption of rice plant caused low rice yield and profit.
Thus, the treatment of none fertilizer application has the highest efficiency (0.2).

Experiment on the timing of fertilizer application
Table3.3 shows a difference between the treatments;higher number of fertilizer application
comes along with high production cost. Treatment of 03 applications/crop had higher cost
than the treatment of none fertilizer application about 5.101 million VND/ha (44%).
The total income is significantly different at 5% between CON treatment and none-fertilizer
application treatment (Table 2.3). However, the treatment of 1-2 fertilizer application/crop
(not including 2nd
application) also has high income but it is not significantly different to other
treatments.

In term of profit, the treatment of 2 fertilizer applications/crop which did not include the one
at 40 DAS could bring the lowest profit and it is significantly different to others. The first two
fertilizer application period (8 and 20 DAS) with high amount of Urea and DAP fertilizer
causes high production cost with no difference in the rice yield. This could be the reason for
the low profit of the treatment of 2-3 fertilizer application/crop. Highest efficiency is recorded
from the treatment of 01 fertilizer application/crop with the profit of 17.030–17.383 million
VND/ha but it is not significantly different to none-fertilizer application or 3 applications/crop
(CON).
The treatment of none-fertilizer application and 1 application/crop have higher economic
efficiency and is significantly different to the treatment of 2-3 applications/crop..
5. Conclusion and recommendations
5.1.Conclusions
118
Based on the collected data and analysis of experimental models during AW crop 2014 at
Kenh 7B with flooding condition and 1 period of water drained-out (30-40 DAS), the
following conclusions are made:
- The sowing rate of 80-120 kg/ha could earn high profit.
- The treatment of none-fertilizer application achieved the rice yield which is not
significantly different to other treatments with the formula up to 80-35-45kg/ha and
earned similar profit ofCON (3.8 million VND/ha),
- 01 time of fertilizer application (8 DAS or 40 DAS) could bring high economic
efficiency but is not significantly different to none-fertilizer application and CON.
- Application of suitable technical interventions could bring higher economic efficiency
to farm households during AW crop. In general, the best practices namely applying the
sowing rate of 80-120kg/ha with none-fertilizer application could earn the highest
economic efficiency with the highest ratio of 2.34.
- Application of none-fertilizer application treatment during the AW crop could greatly
reduce lodging rate in harvesting,production cost and increase profit and green
products.
5.2.Recommendations
The mentioned results indicate that low amount of fertilizer is a potential intervention for
rice production during AW rice crop. However, further study in AW rice crop 2015 (1.
none fertilizer; 2. 1 time at 8-10 DAS; 3. 1 time at 20 DAS, 4. 1 time at 40-45 DAS and 5)
traditional practice) is necessary to confirm the results for better recommendation.
During the AW rice crop, the dry condition could be maintained during the period from 0-20 DAS for better growth of the rice plant and reducing organic poisoning. The upgrading
of irrigation should be more concerned especially in the wet season.

MONITORING AND EVALUATING OF THE APPLICATION OF LOW CARBON RICE
PRODUCTION TECHNOLOGIES 1M6R AND ITS IMPACTS IN KIEN GIANG
AND AN GIANG PROVINCES
Nguyen Hong Tin1, Tran Thu Ha2, Chau My Duyen1, Nguyen Van Sanh1
Abstract
The Vietnam Low Carbon Rice Project (VLCRP)’s technologies were designed and developed from the advanced rice farming technique namely “one must - five reductions” combines with the smart application of Alternate Wetting and Drying (AWD) water management and precise fertilizers application for optimizing the economic, social and environmental impacts. Since 2010, VLCRP has piloted and further refined their low carbon rice production technologies for improving production efficiency and protecting environment that including the reduction of green house gas emissions. As such, VLCRP’s low carbon rice farming technology has been named as one must do, six reductions (1M6Rs), in which, the sixth reduction the Greenhouse gas emission and negative impacts on environment. The VLCRP project’s 1M6Rs was demonstrated and extended over 11 crops in Kenh 7B cooperative, in Thanh Dong A commune, Tan Hiep district, Kien Giang province and Phu Thuong cooperative, in Phu Thanh commune, Phu Tan district, An Giang province. In Kien Giang, the project was undertaken on the rice fields of 265.63ha corresponding to 167 households (farmers). Similarly, in An Giang the project was conducted on the rice fields of 274.81ha corresponding to 254 households. The project’s Monitoring and Evaluation system were designed to monitor the application, evaluate the impacts and provide timely feedback during each and all crops to the communities, farmers, local authorities, DARD and Extension system. Key monitoring and evaluation indicators include (i) diffusion and expansion of 1M6Rs application in the project areas, impacts and technical effectiveness of the 1M6Rs through visual indicators encompassing rice yield, total revenue, total production costs and farmers’ farming practices, (ii) advantages and disadvantages in 1M6Rs application and desirable measures to support farmers, (iii) socio-economic changes and environmental impacts through integrated gender empowerment in rice production. As such, all project activities and its impacts are closely monitored and fully evaluated by each and all crops vis a vis the reduction of production costs, seeds density, fertilizers and pesticides application while increasing rice production efficiency to improve farmers’ livelihoods; as well as project impacts on socio-economic changes and gender equity support the community’s sustainable development.
Household farming diaries and questionnaires were used to collect data on technical (practice) and financial (cost) effectiveness including land preparation, seeding, pesticides and fertilizers application, rice caring, and harvesting. Furthermore, GPS and GIS tools were employed to determine positions of farmers (land parcel) applying the 1M6Rs technology in the field and on digital map.
Study results show that number of households (farmers) and land areas applied the 1M6Rs technology increases significantly over cropping seasons in both project regions, Kien Giang and An Giang. 1M6Rs technology helped farmers to sustain and increase their rice yield, reduce total

production costs whilst achieving significant co-benefits of social, economic and environmental improvements as compared to pre-project intervention. The project has developed the appropriate and effective tools to monitor, manage and evaluate the farmers’ adoption and application of 1M6Rs rice production technology in An Giang and Kien Giang provinces.
Key words: 1M6Rs expansion, water saving, project monitoring and evaluation, technical efficiency.
1. Introduction
The VLCRP has been undertaken since 2010 in the Mekong Delta. Kien Giang and An Giang
provinces are the two ffrontiers in applying the advanced rice cultivation techniques to
increase rice production effectiveness. VLCRP’s overarching goal is to increase income and
improve livelihoods for rice farmers and their communities by applying the project’s
introduced 1Must 6 Reductions (1M6Rs) technology. In Kien Giang, the project was
implemented on the rice fields of 265.63ha covering 167 households which were organized
into 5 Production Groups numbered Group 1, 3, 5, 7, and 9 (Statistical data at the Kenh 7B
Hamlet Committee, 2013). Similarly, in An Giang the project was conducted on the rice fields
of 274.81ha corresponding 254 households grouping into 5 such as 1, 2, 3, 4, and 5, that
located in Phu Thanh commune, Phu Tan district, An Giang province (Statistical data at the
Phu Thuong Cooperative, 2013).
VLCRP designed the demonstration plots to assist on-farm observation and learning for
farmers. Farmers in project areas were organized into relevant Production Groups for learning
and exchanging their best practices for applying the 1M6Rs technology every crops.
Monitoring and evaluating 1M6Rs application in rice production of rice community,
particularly priority groups such as women, poor and nearly poor farmers, landless farmers to
have reasonably supportive technical solutions is an important activity of the project.
This M&E study is designed to monitor, evaluate and provide feedback for each crop on the
following key results.
(i) The rate of the diffusion and expansion of 1M6Rs application in the project areas, its
impacts and the technical effectiveness through the visual indicators encompassing
rice yield, total revenue, total production costs and farmers’ cultivating practices;
(ii) The aadvantages and disadvantages of 1M6Rs application and desirable measures to
support farmers in 1M6Rs application;
(iii) The socio-economic changes and environmental impacts through gender-oriented
activities in rice production.
Through its M&E system, VLCRP project activities and impacts are monitored and evaluated
fully and effectively for every crops, particular in reducing production costs, seeds
application, fertilizers and pesticides use while increasing rice production efficiency to
improve farmers’ livelihoods; as well as project impacts on socio-economic changes and
gender balance for a sustainable community development.
2. Research methods
2.1 Materials
− Household Farming Diary (HFD) was designed to include items correlative witheach
rice cultivation process, such as land preparation, seeding, fertilizer and pesticide
121
application, caring and harvesting. Farmers were trained on using the HFD to collect
data according to the rice growth duration, 7 times per crop on average.
− GPS tool, GIS and GoogleEarth softwares were employed to identify land plots
(farmers’ land parcels) applying 1M6Rs technology on the field and on digital maps.
− Excel and SPSS softwares were used to input, process and analyze collected data.
− Semi-structured questionnaires were used to collect baseline data, and post-project intervention on both farmer groups inside and outside project areas.
2.2.Methodology
2.2.1.Time and locations
- Research time: the study was conducted from Summer-Autumn season (HT) in2013 to
Autumn-Winter in 2014 in intensive rice areas (3-crop per year) in the Kenh 7B cooperative
(Kien Giang) and the Phu Thuong Cooperative (An Giang).
2.2.2 Research process
− HFD design: the HFDwas designed based on required data to evaluate their benefitsand the effectivenessof applying 1M6Rs in rice production. The HFD was given to farmers
for their comments and suggestions, edited by local technicians and experts before
formally used; and appraised at the end of each crop for appropriate update to suit
farmer’s literacy.
− Seasonally, farmerswhom apply 1M6Rs technology are documented and registered; then
a community meeting is organized to plan project activities (including HFD recording)
with participation and support of stakeholders and experts from various organizations
such as Mekong Delta Development Research Institute-MDI (Can Tho University), An
Giang and Kien Giang Departments of Agriculture and Rural Development (DARDs),
Advanced Laboratory, technical experts and farmers;
− Distributing and training for group leaders and farmers on HFD recording;
− Updating data in the HFD (participants were MDI staff, local technicians, project leader groups and farmers) according to various rice growth stages;
− Supplementing and finalizing data on technical and financial effectiveness of 1M6Rs at every community meeting based on the meeting schedule planned by the local project
management unit (PMU);
− Analyzing and comparing technical indicators and economic effectiveness;
− For 1M6Rs development content (Land ID)using GPS and GIS
o Digitalizing the project regional maps
o Identifying farmers’ land positions where 1M6Rs technology is applied in
the field(using GPS)
o Updating1M6Rs household locations on the map
o Updating attribute data
o Converting data in GIS to Google Earth and building thematic maps using
MapInfoand ArcGIS softwares.
122
− Besides, rice samples in control rice fields (using traditional practice) and project fields
(1M6Rs application) were randomly collected to analyze rice quality indicators including
rice milling quality, nitrate content and pesticide residues in milled rice.
− There are 3 types of farmers in this research.
o Core farmers are farmers whom participated in research sites
o Non-core farmers (early adopters) are farmers who learn 1M6Rs
technology from core-farmers and apply based on their rice cultivating
conditions
o Control farmers are farmers whom cultivate rice based on their experience
and habits.
2.2.3.Data analysis
1M6Rs technology development: households, land areas applied 1M6Rs were analysed each
crop
Comparison in technical and economic effectiveness indicators: rice production effectiveness
including technical and financial efficiencies were evaluated and compared between 3 farmer
groups as mentioned above.
3. Research study
3.1. 1M6Rs technology development
3.1.1.Kenh 7B cooperative project area (Kien Giang)
Over 5 crops expanding 1M6Rs application, the number of households and rice land areas
applied the technology have been increased remarkebly, especially in the first 3 crops(Table
4.1 and Figure 4.1).Up to the fifth crop, the registered area that apply the 1M6Rs technology
was expanded beyond the project areas.

Figure4.1: Areas and households applied 1M6Rs technology in Kien Giang over 5 crops
Over 5 crops, 1M6Rs was developed widely through project capacity building activities such
as trainings, workshops, community and farmers’ field day. Besides, those activities help to
upgrade knowledge, skills and capacity, and raise awareness of farmers in the project areas.
Farmers gradually change their cultivation habits; now that they can record, monitor and
evaluate well technical and economic collected data.
At the beginning, 1M6Rs technology application faced several challenges in the Kenh 7B
cooperative. Among these challenges, the big problem is changing farmers’ behavior from
overusing input materials such as fertilizers, pesticides and water to 1M6Rs technology
which requires a standard cultivation process. Fortunately, 1M6Rs technology gives visual
benefits over continuous crops,which makes farmers change their mind and action in rice
practicing. Up to crop TĐ-2014 (the fifth crop), data analysis results show that there are
65.24% rice land areas in the project areas applied 1M6Rs in rice production (Table 4.1).
This proves that the project has intensive impacts on changing farmers’ rice cultivation
behavior; in particular, farmers change from knowledge and awareness to action with the
application of 1M6Rs in their rice production (Figure 4.2).
124
Figure 4.2: VLCRP project land plots (households) at 7B Cooperative (Kien Giang)
3.1.2. Phu Thuong Cooperative project area (An Giang)
Similar to the Kenh 7B Cooperative (Kien Giang), the area and household number registered
to apply 1M6Rs in rice production at the PhuThuong cooperative increased significantly over
4 crops (Table 4.2 and Figure 4.3). Many farmers participated in the project activities
voluntarily due to their motivation of reducing production costs. Firstly, farmers actively
observe and participate in the project activities (e.g. on-farm trials, meeting, farmers’ days,
workshops). When farmers recognize that 1M6Rs technology gives benefits to rice producers,
they apply 1M6Rs on their fields. This reveals the true nature of farmers which is learning and
accepting new technologies by observation and action. These results confirm that the project
has used suitable approaches in terms of transferring new technologies from theory and pilot
study to real-life application.
Noticeablyly, there are many farmers who are not included in the project areas still involve in
the project activities and apply1M6Rs technology (Figure 4.4). During the recording ofHFD,
farmers in Phu Thuongcooperative also face several problems because they are illiterate,
unfamiliar to jobs like writing data in books, while others are so old and couldn’t remember
how many input materials they have used in rice production. Fortunately, thanks to the project
participatory approaches, in which farmers help farmers, and advanced farmers help and
support new project farmers, only after 4 crops, most farmers are fimilarwiththe project
activities.

3.2.The organization of HFD recording and community meetings
Data on technical and economic efficiencies are collected using the HFD. This activity is
integrated to and organized at community meetings with the participation of stakeholders such
as MDI staff, local technicians, project farmer group leaders, pilot farmers and early adopters.
Seasonally, a community meeting is organized to plan project activities and to train farmers
how to use HFD to collect data. HFD is printed and provided to farmers every season to
collect data 7 times per crop.
Approximately 7-10 days after rice harvesting, a brief survey to update and evaluate data
collection is carried out. After that, collected data are processed and analyzed to get feedbacks
from farmers at the community meetings in the next crops. Here, farmers can learn and have
experience based on results of data analysis in previous crops.
Data in Table 4.3 present households and farmers ratio participated in community meetings
over crops. In general, in both project areas (Kien Giang and An Giang), the ratio of meeting
participation is more than 70% compared to that of 1M6Rs registered farmers. In particular,
this ratio is very high in An Giang project areas. Frequent participation in community
meetings helps farmers to work well in data collection and 1M6Rs cultivation process.
The main goal of the project and its activities are to help farmers in particular and rice
community in general to increase their capacity and income through the improvement of rice
production. Over 9 crops expanding 1M6Rs technology in Kien Giang and An Giang, rice
areas and farmers accept this technique increase considerably. This result will help improving
rice production through technical and economic features.

3.3 Project technical efficiency
Tables 4.4and 4.5 compares the technical efficiency between models ofcore farmers (pilot),
non-core farmers (early adopters), and control farmers. Accordingly, standard model delivers
the best efficiency in terms of technology, followed by early adopters. These results reveal
that the ratio of farmers using certified seeds in rice production increases more than 60% in
Kien Giang and 75% in An Giang. By contrast, rice sowing density declines 70kg/ha and
50kg/ha in Kien Giang and An Giang respectively. Furthermore, fertilizers quantity and
pesticides application also reduced.

Prior to the project intervention, concept “Alternate Wetting and Drying-AWD” is completely
new to farmers in the project areas. More than 90% of farmers have traditional water
management style (not drying rice fields occasionally in a season). Currently, farmers in the
project areas clearly understand the benefits of, and apply AWD technique in rice production. By
this way, production costs have been declined and therefore financial effectiveness of rice
production increases.
Data in Tables 4.5 and 4.6 reveal that farmers who apply 1M6Rs technology have higher
technical efficiency compared to control farmers (using conventional practice) at specific
times. In both Kien Giang and An Giang, seeds quantity, fertilizers and pesticides application
in the project site are lower than those of non-project areas through T-test analysis. This is an
obvious and meaningful achievement in improving rice production benefits to enhance rice
farmers and community livelihoods.

In general, after 9 crops of 1M6Rs technology expansion in Kien Giang and An Giang,
technical efficiency in rice production is improved clearly. Input factors such as fertilizers,
seeds, pesticides were used efficiently compared to those before the project is implemented.
Farmers not only use lower amounts of inputs, but they also know when to apply. Moreover,
farmers in the project areas have better efficiency in using input factors inputs compared to
that of farmers outside the project areas. It proves that the project has positive impacts and
great contribution to technical efficiency in rice farming.
Besides technical factors, 1M6Rs technology also improves rice quality in comparison to the
traditional practice. Table 4.8 shows that some quality indicators such as white rice and
perfect kernel rates cultivated by 1M6Rs technology were better than the conventional
technique under the same seasonal crop and variety. This result can help to improve market
price as well as enlarging consumption markets for project products.

3.4.Economic efficiency of the project
Technical and economic efficiencies of the project are presented in Figures 4.5 and 4.6.
Accordingly, the pilot model has lowest total production costs and production costs per kg,
following is early adopters. In contrast, the pilot model and early adopters have higher profits
and investment efficiency compared to control model respectively. In terms of production
costs, control farmers invest 20-22 Mil.VND/ha/crop while early adopters invest only 15-18
million VND/ha/crop. Totally, the project helps farmers decrease production costs from
3,500-3,700 VND/kg of rice to 2,760 VND/kg.
Figure 4.5: Economic efficiency in rice production between three models in Kien Giang
130
Figure 4.6: Economic efficiency in rice production between three models in An Giang
Likely, Tables 4.9 and 4.10 compares economic efficiency in rice production between two
farmer groups, inside and outside project areas. It is shown that the total returns between two
groups are not significantly different by T-test. However, input factors such as costs for seeds,
fertilizers and pesticides are different. As a result, profits, investment efficiency and cost
benefits ratio in rice production of farmers inside are higher than outside project areas. In
addition, rice production costs of farmers inside are lower than outside project area that results
in competitive advantage to project farmers. The 1M6Rs helps rice farmers in Kien Giang
improve profits instantaneously declining production costs. These benefits bring more farmers
to involve in project activities. Over 9 expansion crops, the 1M6Rs have been adopted and
applied well to increase early adopters’ technical and economic efficiencies. However, this
achievement is lower than pilot farmers; it means the pilot model is the oriented goal to early
adopters.

3.5.Social impacts
3.5.1. Women participation in project activities and household economic development
Community capacity buildings including gender equality and empowerment for vulnerability
groups are one of key objectives of VCLRP. Activities regarding technology and household
economic management through group meetings have attracted women participation, and the
participatory rate has increased over crops (Tables 4.11 and 4.12).

During women participation in the project, women were provided the required knowledge and
trained skills on rice farming. They have a chance to interact with others in a new
environment, communicate with extension workers to express their problems and difficulties
on rice cultivation. Therefore, their capacity and roles are enhanced, and they assert their
important position in their families. Figure 4.7 and 4.8 shows a remarkable change of women
participation to advanced farming and community meetings after participating in the project.
Women whom are members of the project groups/clubs have an opportunity to participate in
trainings as well as rice cultivation activities.

Women participation in the project has a positive relationship with the improvement of
economic efficiency in rice production. Table 4.13 shows that significant improvement occurs
at both sites of the project in An Giang and Kien Giang. Cost reduction, profit increase,
capital efficiency improvement can be observed after the project is implemented. This proves
that the project activities have provided an opportunity for women to improve their
livelihoods.

Women’s roles and capacity buildings on rice farming are necessary. Through series of
project activities, knowledge and economic condition of women groups are improved.
Moreover, the project helps women to change their perception and raise their roles and
positions in the society. Remarkable results from An Giang and Kien Giang prove to be
worthy development and imply the potential for scaling up.
3.5.2. Impacts on the poor and the landless
There are three groups of farmers participated in both project sites at Kenh 7B cooperative and
Phu Thuong cooperative: farmers with more than 2 ha of land, farmers with 1-2 ha, and
poor/landless farmers with less than 1 ha. Farmers with more than 2 ha are better-off group;
therefore, they are more likely to apply new technology in cultivation than the poor or landless
farmers. However, through suitable approaches such as participatory extension and community
development of the project, all three groups have equal chance to participate (Figures 4.9 and
4.10). In particular,the ratio of farmers in An Giang with less than 1 ha of land who applied
advanced technology from the project accounts for 65-80% over the crops.
Figure 4.9: Farmers participated in project by land size, Canal 7B cooperative
134
Figure 4.10: Farmers participated in project by land size, Phu Thuong cooperative
One of the key objectives of the project is to enhance the adoption rate of 1M6Rs technology
for the poor and landless. The project always encouraged and supported the poor and landless
in all activities, particularly trainings, field workshops and club meetings.
3.6. Environmental impacts
Environmental efficiency could be considered not only at present but also in the future when
chemical fertilizers and pesticides decreased considerably. The project helps farmers reduce
pesticide application both times and quantity application, on average farmers decline 10
pesticides kg/ha/crop. This reduction, associated with suitable fertilizers management make
better enviromental conditions. Besides, the ADW technique prevents chemicals
discharginginto water in the rivers, canals. Therefore, water environment is cleaner, bio-
diversity in canal and river networks is improved. More importantly, reduction in pesticides
and fertilizers use improve farmers’ health and produce safe rice products to consumers.
Table 4.14 shows that rice grains produced under 1M6Rs technology did not content toxic chemicals for consumers according to current standard, especially 3 chemicals such as
Propiconazole, Tricyclazole andAcetamiprid. They are high sensitive chemicals to quality
standard for rice and other agricultural products. Besides, heavy metals such as Pb and Cd
were not detected either. Nitrate content was also below safe threshold. According to WHO
and EC standards, nitrate content is limited to 50 mg/l for drinking water, 300 mg/kg for fresh
vegetable, and 200 mg/kg for foods (The European Commission (EC), 2006).

4. Conclusion and suggestion
The VLCRP project activities meet rice farmers’ objectives and needs in the project areas.
The monitoring and evaluation process indicates below conclusions
- The 1M6Rs is accepted, adpoted, and applied in An Giang and Kien Giang rice
farming areas that is presented through increasing in areas and farmers applied.
- The 1M6Rs helps farmers improve the use efficiency of input factors such as seeds,
fertilizers, pesticides, as well as produces safe rice products.
- The project 1M6Rs helps project farmers have higher benefits thanks to improving
technical and economic efficiencies in rice production. Conspicuously, low production
costs, high investment efficiency and returns, are examples.
- The project has great contribution to rice farmers and community socio-economic
development through the capacity building, particiaption and livelihood imporvement
to women, the poor and landless.
- Beside technological and socio-economic achivements, the project also contributes to
the envronmental improvement by reducing ferrtilizers and pesticides application,
producing rice products without pesticide residues.
- The project applies suitable tools to monitor and evaluate effeciency and development
of project 1M6Rs technology.
- The project produces a smart agricultural process which is accepted by the rice
community.As a result, it is easy to be scaled up to produce high quality, and
environmentally friendly rice products. This is a suitable measure to deal with climate
change impacts as well as generating competitive advantage and trade mark for
Vietnamese rice products.
The project has remarkable achievements. Obviously, it is nevessary to transfer these results
as well as systematizing the project products to locally application. Therefore, monitoring the
development of 1M6Rs technology and study on its environmental improvement, is needed to
be continued.

FINAL PROJECT REPORT ON GREENHOUSE GAS EMISSIONS MEASUREMENT
IN AN GIANG AND KIEN GIANG PROVINCES
Joseph Rudek1 and Tran Kim Tinh2
1. Introduction
The Ministry of Agriculture and Rural Development of Viet Nam formally approved and
recommends rice farmers follow an advanced farming technique named “1M5R” which is
shorthand for 1Must, 5 Reductions. Farmers “Must” use certified seed and seek “Reductions”
in fertilizer, pesticide, water use, and harvest losses as well as sow a lower density of seed.
VLCRP extends that set of practices to 1M6R by adding a reduction in methane emissions, a
potent greenhouse gas (GHG). Greenhouse gas emission reduction can be achieved by careful
planning of water management in the rice paddy. By allowing the soil to dry out during
certain periods of rice production, the soil will become aerobic.Anaerobic bacteria which
produce methane, stop doing so when the soil becomes aerobic thus reducing methane (CH4)
emissions relative to tradition flooded rice techniques.However, aerobic soil conditions
activate another set of bacteria which can release nitrous oxide (N2O), an even more potent
GHG. But reductions in nitrogen (N) fertilizer application rates (which are part of 1M6R) can
moderate N2O emission reductions as this is where the N in N2O originates.
2. Materials and Method
2.1 Experimental design
Experimental design variables are shown in Table 5.1. As there are 3 crops a year, the
experimental conditions for crops 1 – 3 were repeated in the second year. The third crop was
not repeated in AG as this is traditionally fallowed. Fertilizer application rates varied in KG
by season to accommodate variable crop yields by season. VLCRP measured GHG emissions
on 3 farms using the traditional techniques and 3 farms using 1M6R in two provinces of the
Mekong Delta (An Giang - AG and Kien Giang -KG) over a 2 year period.
2.2 Water management
Designing the water management regime was a critical component to the experimental design.
Extensive meetings with farmers groups were necessary to reach an agreement on the
traditional water management regime for use as the Control treatment. The Alternate Wet and
Dry (AWD) Experimental treatment water regime was formulated based on the agricultural
expertise within the VLCRP. Examples of planned and actual water management regimes are
shown in Figure 5.1a and 5.1b.

numbers in the Fertilizer row indicate the nitrogen, phosphorus and potassium content. AWD

2.3 Greenhouse gas sampling and measurements
The USDA GraceNet3 protocol was used to establish the measurement procedure. A sampling
chamber with a dimension of 70 cm in diameter and 100 cm height was used to take gas
sample. Two chambers were placed on fixed basement structures in each field and gases were
withdrawn with a syringe through a sample port in the top of the chamber at zero, 10 and 20
minutes. Gas samples were stored in evacuated vials for transport from the field to the
Advance Lab. Greenhouse gases were measured on Gas Chromatographs at the Advanced
Laboratory at Can Tho University. An ECD detector was used for N2O determination and FID
detector was used for CH4 determination.
3. Results
The amount of methane emitted in An Giang in the experimental plot was significantly lower
than the Control in 3 out of 4 crop seasons (Table 5.2). (During the first crop season in both
AG and KG, the AWD water management regime was not followed in Experimental crop
fields so no experimental treatment was available). Nitrous oxide emissions, while generally
higher in the AWD experimental fields, as expected, were not significantly higher relative to
the control.
Methane and nitrous oxide emissions were converted to CO2 equivalents and added to get
total GHG emissions for each treatment (Figure 5.2). The reduction in total GHG emissions in
the experimental treatment relative to the control were significant in 3 out of 4 and 4 out of 4
crop seasons in An Giang and Kien Giang, respectively. The average annual GHG reduction
in An Giang was 7.7 metric tons CO2e/ha.

139
The GHG emission data from KG (Figure 5.2) are still under review. The emission values
were exceptionally high as were GHG emission reductions as a result of the experimental
treatment. In order to verify the results from these experiments, it will be necessary to perform
duplicate sampling and measurement in coordination with an independent laboratory. This
verification is planned in the second phase of the VLCRP work. The KG results are shown in
Figure 2 in this report in the chance that others might also have found such exceptionally high
rates in research conducted in nearby areas. The GHG emission results from KG should not
be considered final results and should not be cited beyond this report.
Figure 5.2: Chamber, basement and bridge were constructed for GHG sampling
4. Conclusions
Methane emissions from the rice fields in the AG and KG are quite high but the 1M6R set of
management practices are able to significantly reduce these emissions. Nitrous oxide
emissions are not high but can be an important relative contributor to total GHG emissions
when CH4 emissions are low. The AWD water management regime and low N fertilizer
additions (relative to the traditional management) are important to controlling GHG emissions
from rice field. Agronomic data collected by VLCRP and discussed in other sections of this
report show that the 1M6R set of practices also increase yields and farmer revenue, a critical
factor to the proliferation of the 1M6R set of practices to other areas. Future plans include
modeling the GHG emission to allow extrapolation of the results of these measurements to
other fields using 1M6R.

BYAPPLICATION OF 1 MUST 6 REDUCTIONS MODELIN KIEN GIANG
PROVINCE (2012 – 2014) AND ACTION PLAN FOR THE FOLLOWING YEARS
Department of Agriculture and Rural Development of Kien Giang province
1. Development of agriculture and rice production in Kien Giang province
1.1. The roles of agriculture and rice production in Kien Giang province
Kien Giang is a province in the Mekong Delta which has a total natural area of 634,627 ha; in
which, 377,000 ha is rice cultivation land. It also is divided into three ecological zones
including Long Xuyen Quadrangle is affected by acidity condition, annual floods and salinity;
western of Hau River is affected by flooding from Mekong River and U Minh Thuong area is
affected by acidity, salinity during the dry season and submergence in the rainy season.
Thanks to the favorable natural conditions, there are many potential advantages for the
province in development of economy, agriculture, forestry, marine economy, processing of
agricultural and forestry products and services; in which Kien Giang is the country's leading
in rice production and fishery exploitation. According to the statistic office, rice production of
the province in 2012 reached 4.28 million tons/year and 4.47 million tons/year in 2013 and
4.54 million tons in 2014. In particular, Tan Hiep district is one of the major rice production
areas of Kien Giang province which has a total area of 42,288 ha; area of 2 rice crops/year is
36,655 ha, area for autumn-winter crop is around 30,000 ha and the productivity is about
509,103 ton.
Rice production plays a key role in the socio - economic development strategy of Kien Giang
province. Thus, the province monitors all of resources for a comprehensive agricultural
development and positive impacts to the production such as supporting policies, reducing
irrigation costs; investing in infrastructure such as infield irrigation system, agricultural
extension system for production. Many programs, projects, and agricultural development
schemes are implemented such as selecting and production of high quality commercial rice,
establishment of high quality rice production area for exportation through production contract
between farmers and companies, large field model towards VietGAP, industrialization rice
production project, etc. Besides, many technical packages are recommended to farmers in
order to improve economic efficiency, ensure sustainable production and environmental
protection as 3 reductions 3 gains, VietGAP rice production, and 1 must 5 reductions.
1.2. Challenges in rice production and consumption in Kien Giang province
Although the role of rice is contributing greatly to the socio - economic development and food
security not only for Kien Giang but also the whole regional and nation, the challenges in rice
production are recognized as follows: (1) low income and livelihood of farmers is due to high
production costs, increasing diseases and difficulty in linking farmers and market, (2) low
exportation of agriculture sector and low competitive in the market; (3) high vulnerability of
poor households and women is increasing in the rice monoculture area, (4) environmental
pollution of soil and water in rice production area is increasing. These difficulties are
increasing due to the impact of climate change and integration of Vietnam into a competitive
world market.
Therefore, Kien Giang province has collaborated with the VLCRP-EDF project to implement
and scale up the application of 1 must 6 reductions model addressing the mentioned
challenges. At the same time, the action is also orienting to the implementation the state
143
policy of restructuring agricultural sector through the Decision QD889CP with the aim of
sustainable development on socio-economic and environmental protection.
2. Results of VLCRP –EDF
2.1. Cooperation with the VLCRP project in Kien Giang province
The overall objective of the rice production and consumption of Kien Giang province is
expanding technical applications and agricultural development policies towards commercial
rice production, establishing raw material areas to ensure the sustainable agricultural
development for improving the value of agricultural products and increasing economic
efficiency, livelihoods and environmental protection.
The “Vietnam low carbon rice production” project referred as VLCRP has been implemented
at Kenh 7B, Tan Hiep, and Kien Giang province since July 2012 with the fund supported by
Australian Government. The VLCRP-EDF has worked with Can Tho university (MDI and
Advanced Laboratory) and Department of Agriculture and Rural Development of Kien Giang
province designing and standardizing the process of “1 Must - 6 Reductions” model in order
to: (1) reduce production costs and GHG emissions, maintain and increase rice yield, improve
livelihood; (2) organize demonstration plot in community, training farmers on recording and
documenting changes in farming practice, capacity building for local technicians in low
carbon rice production; and (3) enhance partner’s capacity in expanding the project and
finding for financial supports including sharing project experiences.
Based on the memorandum between the Environmental Defense Fund (EDF Ha Noi) and
Department of Agriculture and Rural Development of Kien Giang province; the Department
established the Project management unit ensuring the implementation of the required
activities, financial management and progress report:
- Project manager – Officers from DARD: deploys and directs the project activities in
community; cooperates with EDF and partners ensuring achievement of targets; and reports
the project results to EDF and senior officers.
- Extension center: plans and assists the manager in implementation, directing the activities in
community, technical support for farmers, etc; cooperates with specialized agencies, local
authority and partners to monitor the activities; periodic report.
- Local authority in Kenh 7B: participates in directing and mobilizing farmers applying “low
carbon rice production” process; expanding project area;directing the application of
alternative wetting and drying;cooperates to organize activities raising awareness on farming
practices and improving livelihoods.
2.2. Results of cooperation with VLCRP-EDF in Kien Giang province
Economic efficiency
The implementation of research models (AWD, AWD + Trichoderma, and Control) shows a
high potential of the model AWD. The model of AWD always achieves higher efficiency than
traditional practices such as 10% higher in rice yield (0.6 t/ha), 48% higher in profit (7.3
VND/ha) and saving about 43% of water.
Impacts on environment
Thanks to the project, farmers’ awareness have been raised and trained; they have reduced the
amount of fertilizers, pesticides and water significantly comparing to traditional practice
about 30% – 40%. Aside from reducing production costs, decreasing uses of fertilizer and
144
chemicals also improves the quality of rice, reduces impacts on environment and bad effects
on human health. Measuring GHG in the models were designed and conducted by experts of
EDF and Advanced laboratory of Can Tho University; the results show that the GHG
emissions in AWD model is lower than those in Control model.
Impacts on social aspects including women empowerment in agricultural production
Impacts on social aspect: The farmer community is more active in participation in the project,
sharing of experiences for livelihood development and raising awareness in environmental
protection with the more participation of poor households and women. The project has
established 5 farmer groups with 133 farm households; in which, 26% are poor households
and women (35 households). In 2015, five new women groups are established with the
participation of 58 farm households in which 20% are poor households (12 households).
After two years of implementation, farmers are more aware about economic and
environmental values of the 1 Must 6 Reductions model. There are more households willing
to apply the new model of the project; there had been more than 95% of farm households
applied the technique since the third rice crop of the project. The project also plays a part in
organizing and linking farmer groups to activities of local authority for improving
cooperative’s activity and management capacity of local authority towards the establishment
of large field model and new style of rural area.
In order to ensure the complete application of farmers, the project also links capacity building
(especially women farmers) and conducting on-farm research. There are several trainings and
meetings during one season for ensuring the production plan, recording “farm diary”,
calculating of economic efficiency as well as the complete process of 1M6R. After 6 rice
crops of the project, there are 3,915 participations of farmer in which, there are 618
participations of women.Besides from periodic meeting of the group, the Women Union in the
community also cooperates with the project organizing training for women-farmers about
1M6R process, household management, role of women in agricultural production.
Large scale application of 1M6R:
In order to apply the process of 1M6R on a large scale, the provincial authority integrates the
“large field model” into the project areas applying on 270 ha with the requirements of using
certified seed, reducing sowing rate, applying appropriate nitrogen fertilizer and IPM,
applying alternative wetting and drying technique, decreasing CH4 emission and post harvest
losses. After 6 rice crops, the total area of application are 1,479.55 ha; in which, 923.18 ha are
from provincial budget and 556.37 ha are funded by DFAT. After the accomplishment of the
project in winter-spring crop 2015, the process of 1M6R has been applied in Kenh 7B with
the total area increased by 200% (from 270 ha/crop to 525 ha/crop). Particularly, in Tan Hiep
district, 36,000 ha are applied the new technique of 1M6R along with investments for
upgrading irrigation system by the decision of local authority to ensure complete application
of alternative wetting and drying method.
The technique of 1M6R has been extended into the agricultural development program of the
province for improving economic efficiency and protecting environment as following:
- At commune level: Applying the technique of 1M6R on rice production area contributing to
the development of 4 criteria of new rural area and integration of community participation
(women, farmers, and groups).
- District and provincial level: Linking and developing sustainable large field production
promoting Green agriculture program with green products, less impacts on environment,
145
reducing GHG emissions and improving farmers’ income towards sustainable development in
the future.
2.3. Advantages and disadvantages
With potentials, Kien Giang province could develop in a new direction of green agriculture
with high productivity for exportation, increasing product value and economic efficiency,
reducing GHG emissions, etc. Thus, the application of 1 Must 6 Reductions technique is a
long-term vision with high attention by the authority and sectors.
In order to manage and ensure the project’s progress; Department of Agriculture and Rural
Development assigned officer to work and coordinate with EDF, partners and local authorities
including Party, People Committee of Thanh Dong A commune and Kenh 7B cooperative
engaging in directing and encouraging farmers to apply new technique, expanding project
area; directing the application of AWD, following sowing calendar of the community;
The collaboration with local organizations (Farmer Association, Women Union, etc.) is
concerned and prioritized by the local authority for raising awareness on farming practices
and improving households’ livelihood.
The consensus of the farmers in the application of new techniques has contributed
significantly to the expansion and maintaining the activities towards project objectives. After
the first two rice crops, farmers in the community were willing to participate in the project
and apply the techniques of 1 Must 6 Reductions; they also completed the requirements of the
project as recording production notes, applying AWD, reducing seed rate and fertilizers,
recording agronomic characteristics and participating meetings for taking good care of the
crop.
Application of 1 Must 6 Reductions technique is necessary and urgent for agricultural linkage
for increasing value added and sustainable development towards climate change. However, in
order to apply the technique of 1 Must 6 Reductions, the following issues should be
considered as follows:
Firstly: uncompleted irrigation system and difference in field level affecting the application of
1M6R-AWD method.
Secondly: difficulty in electric system affecting to irrigation and mechanization in production.
Thirdly: Problem in recording by farmers causing difficulty in confirming the process,
effecting product value due to barriers in traceability and certification procedures.
Fourthly: Products from the process are not certified yet which could not attract farmers
applying new technique;
Fifthly: Weak connection between producers and local traders (food companies) in rice
buying contract with farmers.
3. Future plan of Kien Giang province
After reviewing and evaluating the results of the project, the provincial authority will develop
and expand the model in Tan Hiep district and whole province under the Government
program on joint large field production associating with environmental protection - reducing
greenhouse gas emissions to cope with climate change in agricultural production.
From 2015 onwards, Kien Giang province will continue to implement and integrate the
project into “large field model”, demonstration of 1M6R-AWD to improve rice production,
increase farmers' income and reduce greenhouse gas emissions to climate change adaptation.
146
Based on the results of the demonstration, the provincial authority will coordinate with local
authority to expand the 1M6R-AWD model for developing high quality rice production area;
enhance rice value chain for competition and integration of Kien Giang province, and to meet
the criteria for building “new rural model”.

AN GIANG RICE CULTIVATION MODEL TOWARD
ON SUSTAINABLE AGRICULTURE DEVELOPMENT
An Giang Department of Agriculture Development (DARD)
1. Background
An Giang province is located in Southern part of Mekong Delta and upper part of Mekong
River, combined by delta and mountain with total natural area about over 353 thousand
hectare, in which agriculture land more than 297 thousand ha, forestry land approximately 14
thousand ha. An Giang province has 8 districts, 01 town, 2 cities with total 156 villages,
wards and towns. Total population is 2.15 million in 2014.
In whole province, more than 80% population with their livelihood belong to agriculture, rice
is the main farming and contributes to national food security and total export quantity of
province. In recent, An Giang has been improved soil fertility, irrigation systems and train to
farmers on rice farming techniques packages, intensive rice farming and enhancing rice
production area. From 2001, total paddy rice sowing area is 459.051 hectare, average rice
yield reaches to 4,6 tons per hectare to 2014, total rice area increases up to 625.918 hectare,
average rice yield reaches to 6.46 tons per ha. Total production in whole province has
increased from 2,1million tons in 2001 to 4,04 million tons in 2014. Under total production,
An Giang is the second province for rice production in whole country.

However, rice production and its business is facing with the difficulties: farmer’s low net
income because of high production cost, individual production and market connection
network. Moreover, rice production and farmers cope to many risks from disease outbreak,
environmental pollution, flooding and water source scarcity,changing climate,…
Consequence, rice farmer’s income is unstable.
2. The achievements of high techniques and scientific applications in rice production, An
Giang province
148
An Giang province and some provinces as Dong Thap, Can Tho, Kien Gang, Tien Gang and
Long An are famous places for flooding rice production. After 1975, with many
improvements of high techniques and scientific applications in rice cultivation, the
development of irrigation system for drainage and irrigated water in rice field, high
mechanism development, and the diversity of modern rice varieties, as result, increased crops
per year, intensive rice farming, therefore, rice yield and production increases dramatically.
Beside on increased rice yield, rice productions are focused on good quality, highly efficient,
increasing completion and sustainability in An Giang. The consideration of high techniques
and scientific application in rice production is always invested by An Gang’s government;
some achievements have been indicated from this investment such as
- For rice varieties: selected high quality varieties, high yield, high adaption to topography
and soil types in whold province, the stability of all phenotypes have been maintained in long
time: AS996, OM4900, OM2517, OM4218, OM2514, OM6976, CK92 (sticky rice),…
- The socialization of seed production has good results thoughout the training program “See
selection-cross-breeding skill” from Mekond Delta Develoment Research Institute (MDI). Up
to 2014, there were 187 seed production groups, 31 enterprises in seed business sector, seed
source from farmer’s produce and these enterprises have been supplied to the farmer’s need of
production about more than 90%.
- Paddy rice production applied to the techniques packages as IPM, FPR, 3G-3T (3 reduction-
3 increasing), helping farmers to reduce production cost, increase net income, currently, total
rice production area with applied 3 G3 T program is 93,8% of sowing area.
- 1P-5G (1 Must-5 Reduction) program: conducted in An Giang from 2009, Ministry of
Agriculture and Rural Development (MARD) was certified as a new high technique in paddy
rice farming until 2014. The percentage of rice area applied 1P5G per total rice sowing area
was 38,5%.
For good 1P5G techniques applied (wáter reduction), the cooperation of IRR, Center for
Energy-Agriculture Machinary (Nong Lam University-Ho Chi Minh City), Plant Protection
Department, An Giang DARD have presented the new tractor for the leveling the surface of
rice field by laser beam, combining to 1P5G program. The leveling rice field method by laser
beam supported farmer useful water management, water use and other agro-techniques with
high efficient. From finance investment of VCRLP Project, 2012-2014, An Giang DARD
have been invested to some farmer’s groups and cooperative, 6 new tractors with laser beam
equipment. Utill the end of 2014, there was 165 hecta of rice field leveling by laser beam.
- Machinalization program in rice cultivation was conducted in 2008. Up to 2014, there were
2.229 combine machines in An Giang province, therefore, it can be guaranteed 98% of
harvested rice area by combining machine. There were 2.544 dry machines and more than
75% rice quanlity can be dried out by these machines.
- Rice farming “Large Scale Field”: An Giang DARD has supported to many enterprises for
the development of conected production program as value chain program and others. As a
result, the rice area under this program has been increased sharply, 34.200 ha in 2014,
increased about 200 ha in 2013 (in 2012, 22.950ha). The farmers with large rice field area
usually is main core of this “Large Scale Field” program. The dominant farmers have more
than 1 hecta. Almost farmers involed in value production chain program must apply 1P5G and
removal of unequal rice plant on the rice field.
149
Nevertheless, the development of farming model must be considered from many solutions as
techniques, infrastructure, production, market connection toward on fresh rice quality,
however, the orientation of green agriculture development under restructuring agricultural
sector is limited in An Giang.
3. The development of GHG reduction-rice cultivation program under 1P6G (1 Must 6
Reduction) towards on sustainable agriculture development
3.1. Participating in project and implementation
Field trial experiment conducted to training, feedback, and spread out new techniques to large
rice production zones toward on sustainable agriculture production, restructuring agricultural
sector in An Giang province; Center for Agriculture Extension-An Giang DARD and Mekong
Delta Development Research Institute have carried out the project “ Vietnam low carbon rice
program” funded by Environmental Defense Fund (EDF) at Binh Hoa Village, Chau Thanh
district, An Giang province from 2010-2012 (4 rice crops).
From 2012-2014, Australia Government, EDF, MDI, Advance Laboratory-Can Tho
University and An Giang DARD continuously perform this project throughout 5 rice crops at
Phu Thuong Cooperative, Phu Thanh Village, Phu Tan district.
The VLCRP project based on 1P5G technique and alternative wet and dry technique (AWD),
fertilizer management to develop the 1P6G standard for good rice cultivation in order to
reduce production cost, high yield, good rice quality (fresh rice) and market connection
throughout “Large Scale Field” program. Moreover, the VLCRP project helped capacity
building for local commune, authorities, and mainstreaming gender, emphasized on enhancing
farmer’s awareness and cooperative’s operation orient to green agriculture development with
social-economic efficiency and environmental protection. The project orientations and
activities were scientific basis and experiences for green agriculture development, in
particular, rice farming development. In addition, it could be contributed to restructuring
agricultural sector in the future in An Giang province.
3.2. The achievements of VLCRP project affects on green agriculture development
Over 5 crops for implementation (from Winter Spring 2012-2013 to Summer Autunm 2014),
field trial experiments included: (1) 1P5G and AWD; (2) 1P5G and Trico treatment + rice
straw ploughing + AWD; (3) Control: farmer’s traditional practice. As a result, the VLCRP
has selected “1P6G” rice farming-this model has different to traditional farming model
follows:
For economy:
To help farmers increase net income about 9 million VND per ha per crop (40%) because of
seed reduction 43%, 23% Pure-nitrogen fertilizer, 48% water amount irrigation, 2-3 time
reduction for pesticide praying, sticky rice yield increase about 0,8 ton per ha per crop
(approximately 11%).
For environmental impacts:
Because of fertilizer, pesticide praying, water reduction, it’s leading to mitigate environmental
impact in canal and health communities. In addition, the good impact is saving water
irrigation and reduce GHG about 8,1 tons CO2 per ha per year. The good environmental
impact has been discussed by each crop. Therefore, communities, local government and
women were increased their awareness in rice cultivation at project zones and other rice zones
in An Giang.
150
For social impacts, community’s organization:
Community’s capacity building: the changing from traditional rice farming practice to new
practice (1P6G) for high economical efficiency and low environmental impacts are so
difficult. For this reason, the operation of farmer’s groups in cooperative, mainstreaming
gender (women) and poor farmers participatory was specially prioritized. Thereby, training to
1P6G technique, trial experiment performance, farmer’s group operation and organizing
meeting about sticky rice farming process and connecting to rice selling enterprises was very
important during the project’s activities.
From the achievement of sticky rice yield and high net profit enhancing, the VCLRP project
have participated by other farmers with high attractive impacts: from 20 farmers at the
beginning, 15 hectare (crop 2) to 155 farmers, 282 hectare (crop 5) at the end of project’s
fund. Project was established 5 farmer’s groups with the same profile (similar to irrigation
system and management, sowing time, agreement, high awareness approach to new
knowledge and new farming techniques). With the development and farmer’s group meeting
(7 times per each crop according to rice vegetable period) in farming techniques applied,
household’ account by HH’s diary recording, market connection pathways…have been helped
the rice community, poor farmer, women were equitized to participate new rice farming and
less production cost and access to market connection.
For integrating gender and local government in the development of new rural village
Though project activities, An Giang VLCRP Project’s Board has integrated some activities in
local development program:
- The development of new rural village: based on the activities of local village under new
standard criterions, project have been integrated the rice activities towards on high profit, poor
mitigation, environmental protection, farming operation which involved in the village’s plan
and program.
- Integrating the women roles and gender equity though training course and develop women’s
group: organized 13 training courses, 445 women were trained to rice farming technique
“1P6G” in village and district.
Furthermore, the activities of project’s framework have been trained the 1P6G technique for:
26 staffs of Women Association and Farmer Association, 50 local staffs of local institutions
of Phu Tan district.
- Though project’s activities, extension stations have improved about organization skills,
extension methods and transferred new techniques to farmer’s groups/communities’ groups.
3.3. Upgrading the rice production chain in “Large Scale Field” program
For the achievements of project have created the connecting pathways to actors who
participating in rice production chain and completion:
- Input actors consist of enterprises for seed supply, fertilizer and pesticide must be followed
the criteria of 1P5G and regulations of agricultural institution and management.
- Horizontal connection of product chain must be though organizations and capacity building
for farmers by the development of farmer’s group and applied 1P6G technique.
- Vertical connection: the connecting of product of farmer’s group to enterprises must be
interested. Thereby, enterprise’s network of Vinafood II will be involved by general director
151
boar in the action plan and business activities under the strategy of fresh rice development and
high market competition at Mekong Delta.
- Established rice production chain under “Large Scale Field”: Agriculture institutions have
more active for supporting enterprise developed connecting farming models based on value
chain and large scale field program.
Though creation and upgrading rice value chain under large scale field program was based for
development of fresh rice, low environmental impacts and low GHG emission. These were
foundation for restructuring agricultural sector according to national government orientation
with more achievements.
On the other hand, the program of USDA for the capacity of national extension have visited,
training, exchange experience at project area (Phu Thuong Cooperative).
Some lessons learned during the project implementation
For implementation, applied to new improved agro-techniques in general, especially, low
GHG emission in rice production need to be considered:
- The attention, supporting from institutions and local governments;
- Farmer’s participation: high awareness, voluntarily;
- Techniques supporting and capacity building for local institutions;
- Farmer and technique staffs must be made the same agreement about the technique process
though farmer’s group meeting, community capacity building
- Because of different farmer’s ability (skills and education), for acceptation of new
techniques by farmers, it need to be implemented step by step and based on the agreement of
farmer’s community;
- The coordination: Local staffs, core farmers and organizations (farmers, women) must be
coordinated in the propaganda and mobilization;
- Improving professional qualification and knowledge (method, contents) for technique staffs
and extension staff in the activities of technique transformation at communities with more
farmer’s attractive;
- Applying appraisal policy for the good performance farmers (following the procedures and
advanced technology) to encourage their participation;
- Integrating the local policy and action programs, in particular environment, gender and
building new rural village.
4. Planing for An Giang Province from experimental models at Phu Thuong
Copperative – Phu Tan district
- Planning for 2015 at Phu Thuong Cooperative: in spite of the first success of the project
mentioned above and the project ends at the end of 2014, the technical changing, production
organization, and market connection within farmers and the enlargement scale for whole Phu
Thuong Cooperative are limited. Though, during the meeting with Director of project
VLCRP-EDF, and CTU’s technical support and enhancing the capacity, An Giang
Agricultural Sector has planned and maintained the activities at Phu Thuong Cooperative in
2015. The activities include continuing the group activities, following and evaluation in order
to have the better planning for large field program and new rural communes and restructuring
the rice sector in the Province in future.
152
- Large field program: An Giang Agricultural Sector is applying “Large field program” for
rice production, which applies technical procedure “1M5R” for area of 71.000 hectare in
2015. Agricultural Sector continuously prefects and implements large field planning for the
period of 2015-2020 and calls for participation from business.
- Development of the infrastructure for rice production area in An Giang: Province is
improving the system of irrigation canals, drains regulating infield, leveling the farm. These
will be the foundation for large field rice production following the process “1M5R” integrated
with water management, i.e. replicating application model for rice cultivation in greenhouse
gas emissions (1P6G).
- Enhancing the information and communication activities on rice cultivation in greenhouse
gas emissions by integrating agricultural extension training, cooperating with Women Union,
Farmer Union on communications programs (Department of Agriculture signs the integrated
calendar with Farmer Union).
- Integrating in the restructuring project of An Giang Agriculture: rice production from width
to depth, stabling the growth, producing the high quality goods through productivity,
effectiveness and competitiveness improvement Rice value chain is formed and developed
with the diversified associated production forms such as: horizontal link and vertical link.
Implementation of large field model comes to reality, and selects the good performance
enterprises. Research application and scientific - technical advances carry the investment
interest from rice seed production to production, harvesting, processing and preservation and
market.
Undertaking of the Government and the Ministry of Agriculture is greenhouse gas emissions.
For An Giang province, where agricultural production is a strength, application and
enlargement of the rice cultivation in greenhouse gas emission 1P6G is practical, towards to
stable production, environmental production, green agriculture and building the rice trade in
the economic integration and competition.
Obtaining this result and success, Department of Agriculture and Rural Development in An
Giang province is grateful to the meaningful contribution from Australia Government;
Coordination, technical support and capacity improvement from EDF Project, CTU and
farmer community. Therefore, DARD will implement the effective cultivation model on rice
land and suggest the continuous cooperation on research and project implementation to
perfect the closed process from the clean and safe rice production, increase the value of
women in modern Agriculture to trade –mark rice processing and consumption which helps to
improve the quantity and quality of rice value chain.

LESSONS LEARNT FROM THE VIETNAM LOW CARBON RICE PROJECT (VLCRP) MODEL FOR COMMUNITY-BASED LIVELIHOOD DEVELOPMENT THROUGH THE SUSTAINABLE
RICE PRODUCTION
Ass. Prof. Dr. Nguyen Van Sanh
Objectives:
1. Sharing lesson learnt and best practices including the technical approaches for
community development
2. Recommendations for the replication and scale up of the project’s introduced farming
technique of 1Must 6 Reductions for sustainable livelihood improvement for small and
poor farmer households in the Mekong Delta.
Throughout the project implementation process and its primary encouraging results and
achievements, the following lessons learnt were withdrawn and shared for the sake of
supporting the adoption and scale up of the low carbon rice farming as the community gender-
mainstream sustainable livelihood improvement model in the Mekong Delta.
1. Gender-mainstreaming Livelihood Improvements for the Community
o The community interests and priorities are driven objectives for designing and
implementing the community development activities. The baseline survey is key to
understand the community’s development priorities, their agricultural farming and its
special features/challenges, farming conditions and the community’s current social
economic situations.
o Rural women are one of the major workforces and play important roles in agriculture
production. The gender-mainstream community development approaches will
optimize the capacities and capabilities of the women whilst ensuring that their rights,
their needs for livelihood improvement and gender equity are improving.
o The community’s full participation and engagements are key during the entire
community process. Feedbacks on the results of their livelihoods/agriculture
production must be provided timely and periodically at the end of each crop for their
information and improvements as needed.
2. The technical approach and philosophy for community development
o Application of the Participatory Technology Development (PTD) with the
engagements of the scientist, agricultural extension services, farmers and their local
authorities will optimize the core competencies and ensure the community’s
acceptance. With this approach, the development and further refinement of the
VLCRP’s introduced technique of 1Must 6 Reductions have been well-accepted for
self-application and replication by farmers and their communities.
o Application of the Farmer Field School methodology for building the capacity for the
communities; with the special focus to develop core farmers as community’s resources
o Mobilization and utilization relevant resources and matching fund to leverage the
community’s development
154
o Effective coordination of the local social and economic development plan and the co-
management of the local authorities and mass organization including Women’s
Unions, Farmer’s Association, Veteran’s Association and Propaganda agency.
o Develop the Monitoring and Evaluation system for closely monitoring the project
outcomes/outputs and evaluate the project’s sustainability through major indicators on
economic, social and environment.
3. Integration of sustainable agriculture livelihoods to the local social economic
development plan
o Raising community’s awareness of the ultimate pathway for agriculture production in
sustainable way. From there, conduct the capacity building activities for the entire
community and the local authority system for their co-operation.
o The learning and experience sharing within the project management board and with
external stakeholders/other similar projects should be regular
o Sharing and disseminating the project/crop results with the communities, local
authorities and key stakeholders by each crops. Policy dialogue can be done through
this mechanism in order to integrate the sustainable agriculture livelihood
improvements to the community’s social economic development plan and investment
projects such as the Large Scale Production, New Rural Village, Sustainable Poverty
Reduction and Gender Equity
4. Feedback for Policy Recommendations
Documentation of project results and achievements for the evidence-based planning
and development of the relevant policy recommendations aiming at:
(i) Improve income and livelihood for farmers as part of the New Rural Village
program.
(ii) Increase the production profitability and the competitiveness of the rice.
(iii) Enhance the resources management capacity at community level for reducing
the greenhouse gas emissions and other negative impacts to the ecological system.
The policy recommendations must be evidence-based, practical and relevant and processed
bottom-up from the community to provincial, national and international as appropriate.
