Maize is an important cereal worldwide and weeds are a major constraint to production. A trial was conducted in
Kigumo, Murang’a County, Central Province of Kenya in 2010 to compare the effects of glyphosate and
intercropping maize with Dolicos lablab on weed and maize yield. Treatments comprised of DUMA SC41 and
DK8031 maize varieties, glyphosate, intercropping and weedy arranged in a randomized complete block design
in 5x3 m plots replicated three times and data collected in 3x1.5m area in each plot. Weed scores, biomass and
maize yield were recorded. Data was analysed using Gen Stat software package, treatments effects compared
using ANOVA and the means separated by Student New man Keuls. No significant differences in weed scores,
biomass weight and maize yield in both seasons between glyphosate and intercropping at P < 0.05. Intercropping
and glyphosate had similar effects on weeds and maize yield, the former can substitute herbicide use.
