ABSTRACT: Wheat (Triticum aestivum L.) is the most important crop among food cereals. The experiment was conducted at south eastern part of Ethiopia to investigate the efficacy of three herbicides on weeds and growth and yield of wheat. The experiment was laid out in Randomized Complete Block design (RCBD) with three replication. Treatments were combination of 2, 4-D with pallase, Topic with 2, 4-D, pallase only, weed free and weed check were also included for comparison. The following data collected weed density, tiller number, weed biomass, spike length, seed per spike,1000g weight and grain yield. Statistical analysis of experiment showed that application of pallase exhibited the best performance with minimum weeds density (10.67m2) and higher weed controlling efficacy of 84.4% as compared to weedy check (69 m2) followed by combination of pallase with 2,4-D had 68.6% of weed controlling efficacy and hand weeding. Combination of Topic with 2, 4-D had moderate weed density and with weed controlling efficacy of 63.77%. Number of tillers (8.67/plants), grain per spike (63), spike length (8.67cm) , plant height (75.17cm), Maximum 1000g grain weight (66.67g) and (4161kg/ha) at maturity were recorded at Pallase treated plots. Therefore, application of pallase was recommended for controlling of weeds and increasing yield attribute of wheat.
