Effects of some post-emergence herbicides on growth and yield of maize was studied at rainforest, (7 16 N, 5 12 E) and rainforest-savanna transition (7 31 N, 5 45 E) agro-ecological zones of Nigeria. Atrazine at 3.0 g a.i/ha, nicosulfuron at 7.5 and 40 g a.i/ha, 2,4-D at 0.80 kg a.i /ha, and weedy check were laid out on the field in Randomized Complete Block Design with three replicates. Data collected were subjected to Analysis of variance (ANOVA) using Minitab 17 statistical software. Treatments mean were separated using Turkey test (P= 0.05). Results revealed that herbicides reduce the effect of weed competition, thereby allowing crop to perform optimally. Excellent weed control by density, weed fresh weight and weed dry weight occurred with nicosulfuron treatments, followed by 2,4-D and atrazin. However, atrazine is more effective than 2,4-D in reducing weed growth in rainforest agro-ecology. Nicosulfuron was more effective for weed control than other herbicides in both agro-ecologies of Nigeria and was recommended for successful weed management.
