Traditional and improved varieties of maize, pearl millet and sorghum were planted by small-scale farmers under the direction of the International Institute for Tropical Agriculture in two Nigerian agro-ecological zones: the Sudan Savanna and the Northern Guinea Savanna. Samples were collected fo...

Abstract Introduced maize (Zea mays L.) germplasmcan serve as sources of favorable alleles toenhance performance in new maize varieties andhybrids under drought stress conditions. In the presentstudy, the combining abilities of 12 exotic maizeinbred lines from CIMMYT and 12 adapted maizeinbred li...

A base index involving Striga damage, number of emerged Striga plantsand ears per plant is used for selecting for maize (Zea mays L.) grainyield under Striga infestation. There are contradictory reports on the reliabilityof number of emerged Striga plants for selecting for Striga resistance.The o...

The world population is projected to increase to 9–10 billion by 2050, during which time it will be necessary to reduce anthropogenic greenhouse gas emissions to mitigate climate change. The particular challenge this places on agriculture is to identify practices which ensure stable and productiv...

We analyze the determinants of global crop production for maize, wheat, rice, and soybeans over the period 1961–2013. Using seasonal production data and price change and price volatility information at country level, as well as future climate data from 32 global circulation models, we project tha...

Twenty elite early-maturing (75−90 days) tropical maize varieties grown in three diverse agroecologies in West Africa were evaluated to identify varieties with high kernel-Fe and -Zn and bioavailable Fe levels. Bioavailable iron was assessed using an in vitro digestion/Caco-2 cell model. Signific...

The West and Central Africa Collaborative Maize Research Network (WECAMAN) was instituted with the ultimate goal to help improve maize (Zea mays L.) production in West and Central Africa (WCA). One objective of the Network is to enhance the research capacity and capability of the participating na...

A three-year trial was conducted on a degraded soil in the moist Guinea savanna of northern Nigeria to assess the possibility of improving productivity and economic viability of maize-based systems by incorporating short-season legumes and green manure crops into the cropping pattern. Treatments ...

Whether poultry litter (PL) increases concentration of selected mineral elements in corn (Zea mays L.) grain has not been well investigated. The objective of this study was to determine whether fertilizing corn with PL enriches the grain and other plant parts with selected mineral elements. Corn ...
