Stratifying a broad target growing area of a crop into different ecological zones has been an important first step in plant breeding. To cater for the diverse maize growing environments in West and Central Africa, germplasm development and testing at IITA have been targeted to four agroecological...

Maize productivity relationships were studied at Ibadan in the derived savanna of south-western Nigeria using the CERES-Maize simulation model at six crop densities ranging from 2.96 to 13.3 plants m-2. The absolute growth rate for all plant components decreased linearly with density. The optimum...

The focus of this study is to provide baseline data for agricultural development activities in Nigeria, with emphasis on understanding the dynamics of spatial and temporal change in annual, seasonal and monthly rainfall during the past 30 years (1961-1990), using daily rainfall data. It was found...
