This study modeled the introduction of new early cultivars of millet and cowpea, higher cowpea densities, and various fertilization strategies. Model results were then compared with farmer behaviour before and after the availability of these new technologies. The model correctly identified the tw...

The climate of the West African Sudan savannah (annual rainfall of 600–900 mm and a monomodal rainy season of 3–4 months) is characterized by frequent long- and short-term droughts. Crop growth in the Alfisols and associated soil groups is further constrained by soil compaction, low soil fertilit...

The brief summarizes an evaluation of the impact of one participatory research effort known as diversity field forums (DFFs). DFFs bear some similarities to farmer field schools - an approach to improving crop management practices that involves teaching groups of farmers how to solve problems, se...

The increasing interest in crop-livestock integration in sub-Saharan Africa has emphasised the beneficial uses of forage legumes in cereal-based cropping systems. Forage legume-cereal cropping systems were evaluated in 1989 and 1990 at the ICRISAT (International Crops Research Institute for the S...
