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...

On-farm trials were conducted in 2001 to 2003 in the northern Guinea savanna of Nigeria to evaluate integrated Striga hermonthica control methods under farmer-managed conditions. These included intercropping a Striga-resistant maize variety with cowpea (Vigna unguiculata L.) and also cropping thi...

A study was conducted in Kano and Bauchi States in the dry Savanna of northern Nigeria to determine Striga incidence and infestation and relate these to soil fertility status and yield of maize. A three-stage sampling technique was used to select communities and fields in targeted Local Governmen...
