One year field experiment was conducted during rabi season of 2019-20 at the agricultural research farm (Pilikothi) Tilak Dhari Post Graduate College Jaunpur U.P. The experiment comprised of nine treatments viz. weedy check, weed free(two hand weeding 30 & 45 DAS), Sulfosulfuron at 0.025 kg ha-1, Metribuzin at 0.2 kg ha-1, Carfentrazone-ethyle at 0.02 kg ha-1Carfentrazone-ethyle at 0.025 kg ha-1, Metsulfuron-methyle at 0.004 kg ha-1, Sulfosulfuron +Metsulfuron-methyle 0.030+0.004 kg ha-1 and 2, 4-D at 0.500 kg ha-1, replicated four times in Randomized Block Design. Wheat variety HD-2967 was used as attest crop. Application of Sulfosulfuron+Metsulfuron-methyle 0.030+0.004 kg ha-1 significantly increased the plant height and dry matter accumulation at different growth stages over weedy check resulted into higher yield attributes viz. effective plant population in per m2 (920.25) at harvesting time, grain ear-1 (49.25) and 1000 grain weight (40.00 g). Consequently, highest grain (4546.00 kg ha-1), Straw (6214 kg ha-1) and biological yield (10761.50 kg ha-1) were through controlling weeds by Sulfosulfuron +Metsulfuron-methyle after two hand weeding which was at per Carfentrazone- ethyle at @ 0.025kg ha-1 (3908.25,5811.50 and 9719.75 kg ha-1) followed by Carfentrazone-ethyle at @ 0.020 kg ha-1 and proved significantly superior over rest of other treatments.
