Drought occurs at high frequency in maize production zones in Africa. Carefully controlled moisture deficits have been imposed at anthesis and grain filling stages of maize to develop drought tolerant germplasm. The present study was conducted to examine the potential effects of drought tolerant ...

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...

Availability of extra-early maize cultivars has facilitated the expansion of maize production into savannas of West and Central Africa (WCA). Fifty-six extra-early maize cultivars of three breeding eras;1995 to 2000, 2001 to 2006, and 2007 to 2012 were evaluated for 2 yr under 24 multiple-stress ...
