The nucleus farm, Balegreen Spice
and Grain Development, pioneered
• Mechanizing chickpea farming and
breaking prolonged cereal mono-
cropping
• Out-grower arrangement with
23,000 smallholder farmers to grow
Kabuli chickpea
• Stimulated legume technology
scale up through
• Strengthened seed system
development
• Serve as last mile delivery for
inoculants from MBI
• Grain bulking and delivery to
ACOS for the Monino Kabuli
variety

Conclusions
• N2-fixing grain legumes flexible and ‘best fits’ available for all farmers – rich and poor
• Key for food and nutrition security
• Strong gender focus – legumes are often womens’ crops
• Legume residues are important for animal feed
• Improvement of soil fertility is a co-benefit
• We’re putting legume nitrogen fixation to work in African agriculture
