The objective of the study was to compare the yield of okra grown under different weed management strategies. Field experiments were carried out in 2007 and 2008 cropping season at National Horticultural Research Institute, Ibadan, Nigeria. The experimental design was a split plot factorial fitted into a Randomized Complete Block Design (RCBD) with three replications. Okra was grown on plots with cucumber, melon and pumpkin (as live mulches), herbicide, hand weeding and control, under three nitrogen regimes. Results indicated that melon treatment produced the highest fruit yield (418.86 g) in 2007 while cucumber yield was highest (275.02 g) in 2008. There were significant differences in weed density among live mulches. Lower values were observed in okra grown with pumpkin. Pumpkin as a cover crop significantly controlled weed in both years but results in fruit yield reduction of okra.
