Weed management practices are one of the main problems of cotton production in Ethiopia. Therefore, an experiment was conducted at Werer Agricultural Research Center during the main cropping season of 2015 to determine the number of weeding frequencies and yield loss of cotton crop due to weed competition. A total of four treatments (Weedy check, one hand weeding at 20 DACE, two hand weeding at 20 and 34 DACE and three hand weeding at 20, 34 and 48 DACE) were laid out in a Randomized Complete Block Design (RCBD) with three replications. A total of 15 weed species, belonging to 11 families were identified in the cotton field. The result showed that weed density, biomass and yield were significantly affected by weeding frequency. The un-weeded (zero-weeding) plots had significantly higher weed density and weed dry mass than all the other treatments. Yield attributes, such as number of bolls, plant population and boll weight increase as the weed-free period increases. A seed cotton yield loss of about 80% was recorded in the control (unweeded) plots. This study shows that weeding two times at 20 and 34 DACE resulted in better yield and yield components and is therefore recommended.
