The supply response of the smallholder soybean growers was investigation using a sample of 307 farmers randomly-selected from Jive villages in Kaduna and Kano States of Nigeria. Different multivariate functional forms were experimented but the power Junction was chosen because of its obvious uniq...
The deficient agronomic qualities of the local soybean germplasm and the need to develop varieties with desirable attributes, such as promiscuous nodulation, low pod shattering, sustained seed viability and resistance to bacterial diseases and viruses necessitated the introduction of new varietie...
This study undertakes an ex‐ante evaluation of the effects of alternative technology and policy options on soybean supply and demand in sub‐Saharan Africa (SSA) to 2050. Current soybean consumption in SSA is dominated by cooking oil followed by soybean cake used as animal feed. Due to weak proces...

The IITA in its research for sustainable soil fertility management has passed through several stages during which legume-based systems were always at the forefront. Alley cropping has N yields of more than 200 kg ha-1 with 50% N2 fixation. In the case of Mucuna cover cropping, the ecological bene...
