The Guinea savannas of Nigeria have a high potential for the production of maize because of favorable environmental conditions. Despite this high potential, the yields obtained under farmers' conditions are still very low. Low soil fertility and intermittent drought are among major constraints li...

Maize (Zea mays L.) is a major staple crop in West Africa and has the potential to mitigate the food insecurity in the subregion. However, maize grain yield is severely constrained by drought. A study was conducted at 13 locations in West Africa for 2 yr to determine genetic gains in yield of cul...

Striga hermonthica (Del.) Benth. is a widespread parasitic weed that infl icts damage on maize (Zea mays L.) in sub-Saharan Africa. This is a highly variable root parasite that can contribute to signifi cant genotype × parasite population interaction observed in field trials. The present study wa...

Alamu, E.O.Maziya-Dixon, B.B.Menkir, A.Olaofe, O.[Effects of husk and harvesting time on provitamin A activity and sensory properties of boiled fresh orange maize hybrids]Effects of husk and harvesting time on provitamin A activity and sensory properties of boiled fresh orange maize hybrids

This study evaluated the effects of harvesting time and husk on the proximate composition of boiled orange maize hybrids. Eight fresh orange maize hybrids were boiled with and without intact husk at 100oC using atmospheric cooking method and evaluated for proximate components. The results of anal...

Efforts to identify maize germplasm with resistance to Aspergillus flavus infection and subsequent accumulation of aflatoxins were initiated by the US Department of Agriculture, Agricultural Research Service at several locations in the late 1970s and early 1980s. Research units at four locati...

Striga hermonthica is a parasitic weed that poses a serious threat to the production of economically important cereals in sub-Saharan Africa. The existence of genetic diversity within and between S. hermonthica populations presents a challenge to the successful development and deployment of effec...

Striga hermonthica (Del.) Benth is a destructive parasitic weed to maize (Zea mays L.) in West and Central Africa. The presence of large genetic variation among parasite populations contributes to significant genotype × environment interaction, complicating assessment of resistance reactions of g...
