The population dynamics of major cowpea pests was studied in northern Nigeria during 1992-95 in both the wet and dry seasons. Rainfall cowpea is grown as a subsistence crop, mixed at low densities with cereals. Dry-season cowpea is irrigated or grown on residual moisture in monocultures as a cash...

Population dynamics and migration of cowpea pests in northern Nigeria: implications for integrated pest management
Cowpea is an important grain legume throughout the tropics and subtropics, covering Asia, Africa, and Central and South America, as well as parts of southern Europe and the United States of America. The use patterns, seed preferences, and cropping systems vary from region to region. Insect pests,...
In the decade since the literature on the genetics of cowpea was last reviewed by Fery (1985). Researchers have published numerous cowpea genetics studies, especially on economically important traits. Both qualitative and quantitative procedures have been utilized to study these traits, and consi...
The use of cowpea haulms as fodder is attractive in mixed crop/livestock systems where both grain and fodder can be obtained from the same crop. Traditional farming systems which use the haulms as fodder in Asia, Australia, Africa, and other regions are reviewed. ILRI and I1TA have undertaken joi...
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...

Agrophysiological constarints in intercropped cowpea: an analysis
In the semiarid region of West and Central Africa, farmers traditionally cultivate different cowpea varieties for grain and fodder. However, the grain yield potential and the availability of good quality fodder is limited by several factors: insects, pests and diseases, low and erratic rainfall, ...

Adoption and impact of dryseason dualpurpose cowpea in the semiarid zone of Nigeria
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...
