The yield gap and variability in maize under smallholder systems in two agroecologies in northern Ghana were evaluated using a decision support system for agrotechnology transfer (DSSAT). The model was used to assess (1) the potential yield of maize (YPOT), (2) water-limited exploitable maize yie...

Soybean can contribute to soil N, which may partly be used to improve maize production in northeast Nigeria. However, the efficiency of soybean to fix N can be limited by soil P deficiency. This study evaluated the effect of P application and soybean cultivars on dry matter and grain yield of sub...

Striga hermonthica is a parasitic weed that attacks maize, sorghum and other staple cereal crops and has long been considered one of the greatest biotic constraints to cereal production in Africa. Use of resistant or tolerant maize varieties, a maize–legume rotation using trap crops that stimulat...

The performances of plants and seedlings of 14 tropical-adapted, registered maize hybrids were evaluated under drought stress to assess genotype suitability for off-season planting and to identify parental materials for developing drought tolerant hybrids from locally adapted germplasm. Field eva...

A Participatory Impact assessment (PASS) was undertaken to evaluate the adoption of improved crop technologies by farmers in the savannas of Borno State, Nigeria. A total of 476 people including 288 men and 188 women participated in PASS. These included representatives of 97 farmer groups/CBOs, o...

The aim of this study was to assess the influence of farmers` crop management practices on Striga infestation and maize grain yield. Sixty farmers` fields were randomly selected in nine communities across three savanna zones. About 35% of the farmers had cultivated their fields for over 10 years,...
