Conference Paper 2002

Autor: Singh, B.B. Ajeigbe, Hakeem A.

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 protecti...

Two parasitic flowering 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 ...

Considerable progress has been made in breeding improved cowpea varieties in the last five years. The major breeding objectives were to develop high yielding cowpea varieties for sole cropping as well as intercropping with acceptable seed types and resistance to major diseases, insect pests, nema...

High population growth and consequent pressure for food is driving agriculture towards greater intensification in West Africa. However, due to inadequate use/availability of farm manure and fertilisers, there is a continuous decline in soil fertility and overall crop productivity. This trend must...

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...
