Weed management practices used by small scale farmers determine maize productivity. The
trials were executed in Kigumo district during the long and short rains in 2010 to compare effectiveness
of glyphosate and hand weeding on weed management in maize (Zea mays L.). Treatments were
arranged in a Completely Randomized Complete Block Design replicated three times in a split plot
arrangement. The main plots were two maize varieties DUMA SC41 and DK8031 and the subplots
three weed management practices,(glyphosate, hand weeding and no tillage). Data collected included
weed count by species,fresh and dry weed biomass and maize grain yield. Data was subjected to
ANOVA using Genstat computer software package at P<0.05. Treatments means were separated
by Student-Newman Keuls Test. Results revealed that there were significant differences in weed
count among weed management practices (P < 0.05). Weeds, significantly established faster under
hand weeding than other weed management practices. There were no significant differences among
weed management practices in biomass and maize grain yield (P < 0.05). The two maize varieties
significantly differed in grain yield under different weed management practices, DK8031 under
glyphosate had the highest yield among the tillage practices involved.
