Weeds are a serious and economically more harmful than insects and crop diseases in soybean. Assessment of crop yield and economic losses due to weeds in soybean is an important aspect which helps in designing appropriate management strategies against weeds. A study was conducted at Jimma Agricultural Research Center to estimate the yield loss due to weed competition and determine critical period of weed interference to prevent quantitative and qualitative yield losses in soybean which is paramount for the possibility of developing the management method. Eight treatments including standard checks were used, and arranged in randomized complete block design (RCBD) with three replications. Two hand weeding applied at 25 and 45 days after crop emergence gave maximum yield (20.4 q/ha) and had no significant differences compared with weed free. However, the highest yield loss (60.29%) recorded from the plot received weedy control treatment. This clearly indicates that serious crop weed competition has taken place between the 25 and 45 days after crop emergence to secure high yield in soybean. Generally, weeds contribute 60% yield losses in soybean under Jimma conditions.
