Abstract
Effect of pre-emergence herbicides on weeds and growth and yield of cotton was studied by conducting field experiment. Experiment comprised of ten treatments, viz. weedy check (control), pyroxasulfone 85 WG @ 50, 75, 100 g a.i. ha -1 , pendimethalin 330 EC @ 683, 910 g a.i. ha -1 , pendimethalin 455 CS @ 825 g a.i. ha -1 , Smetolachlor 960 EC @ 1920 g a.i. ha -1 , pyroxasulfone + pendimethalin @ 50 + 910 and 75 + 910 g a.i. ha -1 . Data on weeds and crop attributes were analyzed statistically by applying Fisher’s analysis of variance techniques and least significant difference (LSD) test was applied at 5% probably level. All the herbicides significantly reduced the density and dry weight of Cyperus rotundus and Trianthema portulacastrum compared to control. Among the various herbicides pyroxasulfone + pendimethalin @ 75 + 910 g a.i. ha -1 resulted in minimum weed density (C. rotundus 1.75 and T. portulacastrum 6.50 m -2 at harvest), dry weight (C. rotundus 2.09 g m -2 at harvest) and resulted in the maximum seed cotton yield (2284.19 kg ha -1 ). Pyroxasulfone + pendimethalin @ 50 + 910 g a.i. ha -1 showed minimum (70.90 g m -2 ) dry weight of T. portulacastrum at harvest. Almost 57% higher yield of seed cotton is mainly attributed to more number of sympodial branches, bolls and higher 100-seed weight. While maximum nutrient losses were found in control (N 4-91, P 0.915.88 and K 3.50-81 kg ha -1 ).
