Information on the combining ability, heterotic patterns and genetic diversity of maize (Zea mays L.) inbreds is crucial for the success of a hybrid program targeting the stress environments of West Africa (WA). Studies were conducted in 2011 at four locations in Nigeria to (i) determine the comb...

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...

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...

Ensuring that farming in the moist savannas of Africa is maintained, despite increasing population pressure and agricultural demands, necessitates the sustainable integration of crop and livestock enterprises; a role that forage legumes can fulfill. The potential of eleven herbaceous and two shru...

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...

Infestation of cereals and cowpeas by Striga species constitute a major constraint to increased crop productivity in the savannas of northern Nigeria. Field surveys were undertaken in Jigawa State, Nigeria in 2012 to assess (i) the level and extent of Strgia infestation of cereal and cowpea field...

Availability of multiple-stress tolerant maize is critical for improvement in maize production in West and Central Africa (WCA). A study was carried out to (i) assess a set of inbred lines for combining ability under stressed and optimal conditions, (ii) determine the performance of the testcross...

Striga hermonthica (del) Benth is threatening rural livelihoods in western Kenya where maize is the major food and cash crop. Vulnerability analysis was conducted on a sample of 802 households in eight districts of Nyanza and Western provinces. Farmers perceived Striga as the major cause of pover...
