| dc.description.abstract | Weeds are unwanted plants growing in agricultural lands, gardens, road sides and mainly
disturbed areas where they do not depend on human intervention for their reproduction and
survival. Depending upon density, types, duration of competition, management practices and
weather conditions, weeds may cause a reduction in crop yield. To determine the effect of weeds
on the yield of beans, an experiment was carried out in University of Eldoret research farm in 2017
for two seasons. The area is located in Uasin Gishu county, Kenya and lies at an altitude of 2133
m above sea level. Geographically, the area is at 35o 18’ E longitude and 0o 30’N latitude. The
experiment was laid out as a factorial in Randomized Complete Block Design (RCBD) with three
bean varieties and three treatments. The treatments were weed free plots, weedy plot and plots with
single weeding. The data obtained were subjected to ANOVA using Genstat version 14 and means
separated by Duncan’s Multiple Range Test (DMRT). Results indicated that weeds significantly
reduced the yield of all the three bean varieties from between 12-27%. From the results, it was
deduced that all the bean varieties tested were susceptible to yield loss due to weeds. The study
recommends for proper weed control in beans so as to realize good yields. | en_US |
