Cowpea is important for the provision of both grain for food and fodder for livestock but there is often a trade-off between production of the two. To better understand influences on grain and fodder production, and how these may be utilized. Research was conducted at 5 locations in West Africa u...

A field study was conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semideterminate cowpea [Vigna unguiculata (L.) Walp.] genotypes developed in the Nigerian Sudan savannas in 1974 to 2004. Resul...

Striga gesnerioides (Willd) Vatke, is a major destructive parasitic weed of cowpea (Vigna unguiculata (L.) Walp.) which causes substantial yield reduction in West and Central Africa. The presence of different virulent races within the parasite population contributes to significant genotype × envi...

A cropping system trial involving 2 spray treatments, 2 cowpea varieties, and 9 cowpea–cereals cropping patterns involving two cereals was conducted in 1999 and 2000 cropping seasons in Minjibir. The systems involved different row to row combinations of cowpea and millet or sorghum. Selec...

The average productivity of cowpea in the existing traditional systems is low due to a complex of biotic and abiotic stresses. The biotic factors include insect pests, parasitic plants, and viral, fungal and bacterial diseases. Concerted efforts are being made to develop improved cowpea varieties...

Cowpea (Vigna unguiculata [L.] Walp.) is the most important grain legume in the dry savannas of West Africa, however grain and fodder yields are low (averaging 25 to 300 kg and 450 to 800 kg grain and fodder/ha, respectively) due to biotic and abiotic constraints. Improved varieties and cropping ...

A preliminary trial was conducted to determine if there were variabilities in seedling morphology of selected cowpea varieties and determine their heritability with aim that this could be used in future cowpea breeding for selection at seedling stage. The characters studied include hypocotyl, epi...
