Location-specific nutrient and crop management in rice farming: mobile phone and web-based

decision tools are bringing results of research to farmers

FAO-World Bank meeting Bangkok 15 May 2012

Roland J. Buresh International Rice Research Institute (IRRI)

Rice in Asia is typically produced in small landholdings

• Farming practices and risks vary among farmers and fields

• The best management

for high profit and high yield differs among fields

More than 10 years of research lead to site-specific nutrient management (SSNM)

Partnerships after 10 years (1996-2005)

Science is well documented

Tools are available for farmers

Farmers need quick and easy access to information matching their specific field conditions and needs

Principles of SSNM were used to develop printed guidelines

• Aimed to reach many farmers fast

• Printed materials struggle to transform complex decision making into simple messages

• Nutrient Manager for Rice provides rice farmers with ‘best-bet’ nutrient management for their specific rice field

• Consistent with SSNM principles and current science

• Available as web and mobile phone applications

– Can update in real time – Can monitor use – Can link to other applications

and services

Developed computer-based decision tools to provide rice with ‘precision’

management practices

Example of Rice Crop Manager under development

Name: Juan Dela Cruz Rice crops per year: Two Mobile number: 09171234567 Season: Dry Location: Bilar, Bohol, Region VII Water: Irrigated, tube well Variety: NSIC Rc 222 Direct seeded: 101-110 days seed-to-seed

*DAS – days after sowing

Target yield: 105-116 sacks at 50 kg/sack 4.8-5.3 t/ha (14% MC) Actual field area = 1 ha

AWD

Growth stage DAS* Management practice

1-3 Apply pre-emergence herbicide

1-20 Maintain soil flooding, less than 3 cm water

Early 12-16 Apply 3 bags 14-14-14

21-70 Practice AWD

22-27 Hand weeding

Active tillering 28-32 Apply 1 bag urea

Panicle initiation 43-47 Apply 1.5 bag urea

1) Use tool before establishing crop

2) Provide personalized best management to overcome main constraints

3) Focus on increased income (profit)

Information on anticipated seasonal climate can be used to:

• Estimate attainable yields and set levels of inputs

• Select variety • Adjust cropping

Key ingredients of approach 1. Provide information matching specific needs of an

individual through user-friendly Web and mobile interfaces

• Directly acquire and

provide information

2. Enable interfacing with complementary services

3. Enhance abilities of ‘extension agents’ to get the right information to the right person at the right time • Collaborate in testing, translations, interfacing, refining, and

meeting needs of stakeholders

• Temperatures will increase - More heat stress - Rising sea water levels • More frequent and severe climate extremes - More floods - More droughts

What about climate change?

Genes for nutrient deficiency and problem soil

A C4 rice should increase rice yield, water and nitrogen use efficiency by 30-50%.

No other evolutionary mechanism exists that could be added to a C3 rice so as to deliver

that superior combination of benefits.
