The herbicides application increased number of tillers per m-2, number of productive tillers per m-2, biological yield t ha-1, grain yield t ha-1 and decreased the weed density per m-2. While number of un-productive tillers per m-2, plant height at maturity, spike length, number of grains per spike, 1000- grain weight and harvest index were not significantly affected by herbicides application over the weedy check. Agro-economical analysis of yield data of wheat indicated higher benefit cost ratio in case of Logran Extra 64 WG (2.86) closely followed by Buctril M 40 EC (2.82). Net income was more in case of Buctril M 40 EC than Logran Extra 64 WG. All the prevailing weeds of the crop were effectively controlled by the application of Buctril M 40 EC.
