Community-based assessment of SRI in 12 villages with 60 farmers
in Goundam and Dire, Timbuktu

Implementation approach• 12 villages were enlisted to cooperate in the
evaluation based upon interest
• 5 farmers were selected by each village community to participate = 60 in total
• Community gave assurances of support – e.g., labor, adjusting irrigation schedules
• No gifts! Our ‘gift’ was the technical support– 4 field technicians for the 12 villages
• Good data collection to be done
• Control plot started the same day as SRI

6 Principles of SRI• Transplant single seedlings• At their 2-leaf stage, only
8-12 days old• Spacing is 25 cm x 25 cm
or wider; planted in square• Use mechanical hand
weeder for soil aeration• Minimum water application
during vegetative growth• Application of organic
matter (manure, compost) instead of fertilizer

Land preparation of SRI plots
1. Application of manure (10-15 t/ha)
4. Leveling
3. Breaking up large soil chunks
2. Tilling by hand or by tractor

SRI Nursery
• Mix soil, clay, sand and manure (loose soil)
• Soaking of seeds before planting in nursery (24h)
• Watering, not flooding• Transplantation after 8-12
days
Quantity of seeds used with SRI
6.15 kg/ha
Results
Quantity utilized traditionally
40-60 kg/ha
Reduction of
85-90%

Multiple effects of cono-weeder application
Section not weeded
• Incorporating weeds as green manure
• Soil aeration• Stimulation of root growth• Redistribution of water across
the plot, with leveling effect• Making nutrients of manure
more available to plants
