The main objective of this paper is to discuss the economic aspects of genetic resources in addressing agricultural productivity in the context of climate change and variability in Africa. The paper synthesizes the published literature related to this topic, which has not been well integrated, es...
Food insecurity has become a key issue in the field of development in recent years with major inadequate intake of vitamin A-rich foods. Specifically, vitamin A deficiency (VAD) remains a major health problem among poor developing-country households, especially in Africa. Efforts to combat VAD cu...
Factors affecting cowpea growth in millet/cowpea intercropping were investigated in northern Nigeria. Ecological studies showed that cowpea received from < 30% to > 75% of incident light inside the intercropped canopy. In these light-limited conditions, cowpea varieties with a spreading growth ha...
The genus Vigna comprises seven subgenera and sixteen sections. Cowpea, Vigna tingnicnlatti (L.) Walp.. is an important grain legume crop in sub-Saharan Africa and belongs to the subgenus Vigna. section Ctitiang. Morphologically, cowpea genotypes appear very variable. However, a high level of gen...
The production of cowpea in Africa and America is reviewed briefly. In traditional cropping systems in West Africa, a diversity of both systems and varieties is observed. The contribution of cowpea to overall productivity is small (on average about a tenth of grain yields, averaging 1.5 l/ha), an...
The imponance of cowpea (Vigna unguiculata [L.] Walp.) is underscored by its use as a component in many cropping system combinations in Africa, Asia, and tropical America. Cropping systems research over the past decade has served as a multidisciplinary approach to examine the biological superiori...
