Selection for drought tolerance in two tropical maize populations
(African Crop Science Society, 2003)
Drought is a major factor limiting maize ( Zea mays check for this species in other resources L.) yield in much of the world. The need to breed maize cultivars with improved drought tolerance is apparent. This study compared ...

Nitrogen effects on maize yield following groundnut in rotation on smallholder farms in sub-humid Zimbabwe
(Academic Journals, 2007)
Rotating maize (Zea mays L.) with groundnut (Arachis hypogaea L.) has been proposed as a way to maintain soil fertility and prevent maize productivity declines in the smallholder cropping systems of sub-humid Zimbabwe. ...
