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...

Two parasitic fl owering plants, Striga gesnerioides (Wild.) Vatke and Alectra vogelii (Benth.), cause substantial yield reduction in cowpea in the dry savannas of sub-Saharan Africa. Alectra is more prevalent in the northern Guinea savanna and southern Sudan savanna of West Africa, as well as in...

Most of the farmers in the dry savannas of West Africa plant local varieties of cowpea, millet, sorghum, and groundnut in various intercropping systems with little or no purchased inputs. In this system, the cowpea and groundnut yields are low due to shading by cereals and lack of plant protectio...

Cowpea (Pzgna unguiculata) is grown as an intercrop with cereals in some 9 M ha of West Africa, mostly in the dry savanna. Though grain yields are low (circa 500 kg/ha), it is a nutritious food and dry season fodder. The haulms (leaves and stems) are cut and stored after grain harvest. Cowpea aid...

The cowpea breeding programmes are reviewed and achievements at two major centres of cowpea research, i.e. IITA (Nigeria) and IARI (India), are summarized. Earlyand extra early genotypes are always photoperiod-insensitive, medium maturity varieties could be sensitive or neutral today length, whil...
