Conference Paper 2004

Autor: Singh, B.B. Larbi, Asamoah Tabo, Ramadjita Dixon, Alfred G.O.

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 present study uses georeferenced community level data to study the adoption of improved cowpea in northern Nigeria. One objective of this study is to find out which factors of the community of village level are significant determinants of adoption of improved dual-purpose (DP) cowpea variatie...

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 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...

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...

In the moist savanna zone with a 180 to 190 day growing period, early season cowpea immediately followed by a late season cereal crop can maximize the benefit of the legume to the cereal. Traditional cereal crops for this system are millet and sorghum but new early maize varieties can also be use...

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...

The most damaging storage pest in cowpea [Vigna unguiculata (L.) Walp] is Callosobruchus maculatus (F.), commonly known bruchid. Therefore, concerted efforts are being made at the International Institute of Tropical Agriculture (IITA) to develop bruchid-resistant cowpea varieties. By systematic s...

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...
