Weed is one of the most important enemies of basil production. Therefore, this study aimed to determine the critical weed competition period on growth, yield, and yield components of the basil plant at Wondo Genet and Alage site during the 2017 to 2018 cropping seasons. The experiment was laid out in a randomized complete block design with three replications consisted the treatments of 10, 20, 30, 40,50, and 60 Days After Crop Emergence (DACE), and season-long weedy and weed-free checks were included as a control. In both locations, the yield losses of basil were estimated based on fresh and dried herbage, and essential oil yield. The highest fresh and dry herbage yield of 2,829.10kg/ha and 1,193.06kg/ha from Wondo Genet and 3,101.87kg/ha and 1,148.78kg/ha from Alage were recorded from the weed-free for 60DACE, respectively. Also, the maximum essential oil content and yield of (1.05v/w) and (12.66kg/ha) from Wondo Genet and (1.27v/w) and (14.58kg/ha) from Alage were recorded from the weed-free check, respectively. Based on the estimated value of yield losses the beginning and the end of the critical period of crop-weed competition at 5 and 10% acceptable yield loss levels were determined. Thus, to reduce the yield losses by more than 10%, plants must be kept weed-free within 50 to 60 and 40 to 60DACE at Wondo genet and Alage site, respectively as it is the critical period of weed-crop competition in basil plants.
