Maize is the most important staple cereal crop in sub-Saharan Africa (SSA) and has great potential to rectify the food insecurity in the sub-region. A study was conducted at four locations two each in Nigeria and Benin in 2010 and 2011 to determine the rate of genetic improvement in the grain yie...

Genetic gains from selection for high grain yield and Striga resistance in early maturing maize cultivars of three breeding periods under Stigainfested and Strigafree environments
Maize (Zea mays L.) has the greatest yield potential in savannas of West and Central Africa (WCA). However, production in this agroecology is constrained by low levels of N, drought, and parasitism by striga [Striga hermonthica (Del) Benth.]. Diallel crosses involving 17 extra-early white maize i...

Reliance on rainfall for agriculture and increased climate change and variability pose growing production risks in developing countries. Agriculture in Sub-Saharan Africa is dominated by smallholder farmers who depend mainly on rain-fed agriculture, putting food security at both household and nat...

Agricultural intensification of farming systems in sub-Saharan Africa is a prerequisite to alleviate rural poverty and improve livelihoods. Legumes have shown great potential to enhance system productivity. On-farm experiments were conducted in different agro-ecological zones (AEZ) in Western Ken...

The production of maize is constrained by parasitic weeds, particularly Striga. A study was carried out to document farmers’ knowledge, attitude and practices on Striga control among smallholder farmers across three districts: Kisumu West, Busia and Teso South of Western Kenya. A multistage sampl...

Yield losses of maize due to drought stress (DS) in environments with limited rains can reach 100 %. Introgression of favorable alleles from diverse landraces into adapted elite varieties will improve performance, hence reducing losses. The objective of this study was to assess the performance of...

There is growing interest for yellow maize among farmers and the food and feed industries in West Africa. Testing of maize hybrids in multi-location trials is crucial for identifying adapted high-yielding candidates for quick release. This study was designed to evaluate yield stability of three-w...

Cowpea-maize intercropping causes low yields of cowpea due to shading effect by maize plants. Staggering of dates of planting of cowpea in an intercrop is a potential way of reducing intercrop shading while increasing cowpea yield. Nonetheless, contrasting cowpea cultivars may have differential r...
