Conclusion

WHY “Integration of vegetables into maize/legume - based farming

systems of Babati To optimize productivity and diversifying household diets and

income through promotion of increased consumption of nutrient dense vegetables

Evaluate diverse options for sustainable intensification of vegetables into crop and poultry enterprises and apply innovations that sustainably increase output from the same land area, while reducing negative environmental impacts.

Technology cont….,

2. Healthy seedlings

3. Good Agricultural Practice (GAP)Items Practices

1. Nursery establishment Use of good quality seeds, healthy seedlings, soil, treatment , good management

2. Field and land Management (cultural practices)

Timely planting base on cropping calendar, irrigation

3. Integrated Pest Management (IPM)

(Physical, chemical and biological methods)

4. Crop production Follow recommended demo protocols

5. Crop protection Health seedlings, good quality seeds, fencing, minimal pesticide application

6. Postharvest handling practices

Maturity index, Proper harvest, sorting and grading, packaging, storage and cooling, recipe preparation, preparations for marketing

7. Records Keeping track of what is happening on the farm

GAP- Practices

• Manure application

•IPM

•Mulching

• Proper spacing

• Stalking

• Irrigation

• Weeding

Use of empty water bottles for drip irrigation

Farmers use A. Marygold to control nematode

4. Vegetable –poultry integration

Use of vegetable and vegetable residues as

poultry feed to reduce pre and post harvest loss

Poultry droppings as manure in integrated

vegetable farming systems to enhance nutrient

recycling

Poultry–house preparation in progress

5. Mobile vegetable garden

Benefits Perfect solution for those with limited land Vegetables are easy to access for human consumption and

poultry feed Easy to manage Plants get good air circulation, decreased potential for

fungal diseases attack Keeps produce off the ground, preventing rotten on the

bottom or being chewed by mice or slugs Encourage more women to engage in vegetable production

and consumption

Our findings

Economic:Production Increase Production technologies involved the use of health seedlings and good agricultural

practices (researched against farmers seedlings farmer practices) in growing tomato,

African eggplant and Amaranth. The study shows that, tomato production increased

by 49.87%, eggplant production by 64.37% and Amaranths by 34.91% as follows

Increased tomato production from 35.6 t/ha (FS-FPs) to 58.0 t/ha (HS-GAPs

African eggplant production from 35.9 t/ha (FS-FPs) to 69.5 t/ha (HS-GAPs)

Amaranth production from 51.5 t/ha (FS-FPs) to 72.2 t/ha (HS-GAPs)

The average price for each crop at

the time of data collection in October

2014 was as shown

Crops Av. Price (TZS)/kg

Tomato 2,171.83

Amaranths 1,296.25

African eggplant 8,49.59

Quantity consumed, quantity given as

gifts and losses after harvest are included

in the data, losses after harvest(caused by pest and diseases,

bird eaters) were deducted

Economic: Undiscounted Benefit Cost Ratio

(BCR) The undiscounted BCR was computed from the data collected whereby

Tomato had BCR of 7.7 for HS-GAPs, 6.0 for FS-FPs; African eggplant had

BCR of 3.73 and Amaranths had BCR of 2.43 each obtained from an area of

0.0012ha

The BCR greater than 1 shows that adopting the use of health seedlings (HS)

developed from good quality elite seeds in combination with other GAPs make

vegetables a more profitable farming business though contribution of GAPs is

more evident by the profit margin variation between treatments as shown in the

next slide

Economic: cont...., In addition, the results show the possibility of the family to

generate for:

Tomato: An average income of US$ 59.40 per 0.0012 ha per

season

African eggplant: An average income of US$ 21.03 per

0.0012 ha per season

Amaranths: An average income US$ 8.30 per 0.0012 ha per

season

Environmental impact caused by use of technology

Good quality seeds , Health seedling & GAP (+VE))

1. Incidence of pest and diseases reduction

2. Reduce amount of artificial fertilizer application & pesticide

3. Recycling – poultry droppings as manure , water bottles for irrigation and local containers, mulch, crop residues for livestock feeds e.g. poultry )
