Abstract
Low soil nitrogen (N) and weed infestations are some of the major constraints to maize production in Nigeria. A split-split plot experiment in a randomized completed block design with three replicates was established at two sites with different
agroecological zones. Ikenne (Typic Paleudalf) and Shika (Typic Tropaquept), in Nigeria in 2002 and 2003 rainy seasons to investigate the responses of four maize genotypes (Oba super II, low N pool C2, TZB-SR, and ACR 8328 BN C7) to N fertilizer applied at four rates, 0, 30, 60 and 90 kg N ha-1 and three weed pressure treatments, no weed pressure (week weeding) low weed pressure (inter row weekly weeding) and high weed pressure (no weeding throughout the growing season).
