Cowpea covers the largest area of any grain legume in Africa and is especially important in West Africa where Nigeria and Niger alone account for over 75% of the total cowpea production in the world. Despite successes of international and national cowpea improvement research in the development an...

Agriculture in the dry savannas is intensifying in response to increasing populations of humans and livestock. As a result, increased productivity demands are placed upon integrated crop-livestock systems and more emphasis is on the roles of legumes such as cowpea. Cowpea has the potential to fun...

The research reported here has the potential for contributing to a real improvement in the livelihoods of mixed crop-livestock farming households in the dry savannah zone of West Africa through widespread uptake of improved dual-purpose cowpea (IDPC). This technology offers opportunities for the ...

This paper estimates a more efficient version of an endogenous switching regression model to examine the effects of farmer education—schooling and extension contact—on cowpea production under traditional and improved technology in northern Nigeria. The results revealed significant productivity-en...

The present study uses georeferenced community level data to study the adoption of improved cowpea in northern Nigeria. One objective of this study is to find out which factors of the community of village level are significant determinants of adoption of improved dual-purpose (DP) cowpea variatie...

A classification of the major ruminant livestock production systems in West Africa is proposed. The proposed typology has two major classes of systems-sole livestock and crop-livestock. The sole livestock class has two systems (rangeland-based and landless) and the crop-livestock class has three ...

Impact studies assuming exogenous technology adoption are bound to overstate or understate the true impact of improved agricultural technologies, especially in situations where agricultural technologies are targeted to, or adopted by, a certain group of farmers. This paper examined the impact of ...
