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.
