Cowpea is a major food and cash crop in northern Nigeria, providing nutritious grain and a less expensive source of protein for both the rural poor and urban consumers. A number of improved varieties have been developed combining diverse plant type, and different maturity periods, with resistance...

Sorghum (Sorghum bicolor [L.] Moench) is one of the most important cereal crops grown in the dry savannas and semi-arid regions of West Africa under rain-fed conditions. Although total sorghum production in Nigeria has increased over the years, the average grain yield on farmers' fields has remai...

Striga is a major constraint to crop productivity in the savanna zones of northeast Nigeria. In a community livelihood survey, farmers in the region ranked Striga infestation as the topmost priority constraint. A field survey was, therefore, conducted to assess the level of field infestation by S...

The parasitic flowering plants Striga gesnerioides (Willd.) Vatke and Alectra vogelii (Benth.) are formidable cowpea production constraints in the West and Central African savanna. The two parasites cause substantial yield reduction in cowpea in the dry savannas. A field study was conducted to sc...
