Effect of Post Emergence Herbicides on Growth of Wheat Crop and Their Associated Weeds

The field experiment was conducted during Rabi season of 2019 20 on sandy loam soil at Agricultural Research Farm Pili Kothi , Department of Agronomy, Tilak Dhari Post Graduate College, Jaunpur U.P. . The “Effect of post emergence herbicides on growth of wheat crop and their associated weeds” The experiment comprised of nine treatment combinations and tested in randomized block design RBD with four replications. Experiment consisted of one factors, viz. seven different herbicides in different doses different time applied weed control of wheat crop analysis in superior herbicide in weed control of wheat crop t1 Sulfosulfuron at 0.03 kg a.i ha. Post emergence 28 DAS, t2 Metribuzin at 0.2kg a.i ha. Post emergence 28 DAS, t3 Carfentrazone ethyl at 0.025kg a.i ha. Post emergence 28 DAS, t4 Carfentrazone ethyl at 0.02kg a.i ha. Post emergence 28DAS, t5 Metsulfuron methyl at 0.004kga.i ha.Post emergence 28 DAS, t6 Sulfosulfuron Metsulfuron methyl at 0.03 0.004 kg a.i ha. Post emergence 28 DAS, t7 2, 4 D at 0.500 kg a.i ha. Post emergence 32 DAS, t8 Weed free two hand weeding , t9 Weedy check and results obtained in t6 Sulfosulfuron metsulfuron methyl 0.030 0.004 kg a.i ha 28 DAS superior compare to weedy check and similar in t8 weed free plots. Application of t6 Sulfosulfuron metsulfuron methyl 0.030 0.004 kg a.i ha 28 DAS Were recorded in minimum density of weeds m2 more number of tillers, recorded crop dray matter and at remain least weeds dry matter recorded gm2 as compare to other treatments.
