The effect of different weed control measures was studied in wheat crop. The experiment was laid out in simple RCB design, replicated four times. It was comprised of seven treatments i.e. Irelon 50 SC at the rate of 1.12, Puma S 75 EW at the rate of 0.85, Buctril M 40 EC at the rate of 0.72, Buctril M +Topik 15 WP at the rate of 0.72 and 0.75, 2,4-D (powder) at the rate of 1.20 kg a.i ha-1, Hand weeding after 35 days of sowing and a weedy check was kept for the comparisons. Data recorded were weeds count M-2, plant height (cm), grains spike, 1000 grains weight (g), biological yield (kg ha-1) and grain yield (kg ha-1).The lowest (16.10) weeds m-2 was count in Puma S treated plots as compared to the highest (69.72) recorded in the weedy check plots. Buctril M and 2,4-D were comparable with Puma S. Buctril M + Topik mixture increased grains spike- 1 and 1000 grains weight significantly in wheat. Significant increase was also occurred in biological and grain yield (kg ha-1) with the application of Buctril M + Topik application. It gave maximum of 9236.35 and 2986.43 kg ha-1 biological and grain yields, respectively. Puma S, 2,4-D, Irelon and hand weeding also increased biological and grain yields significantly.
