The effect of four herbicides on weed density and wheat yield was studied.  The experiment was laid out in randomized complete block design with four replications. The experiment consisted of four herbicidal treatments viz. Atlantis 3.6% WG (Ideo + mesosulfuron) at 0.40 kg ha^-1, Proton 50% WP (Isoproturon) at 2.00 kg ha^-1, Cleaner 70% WP (Isoproturon + bensulfuron) at 1.50 L ha^-1, Locker 70% WP (Fluroxypyr) at 0.25 kg ha^-1, and a weedy check. Results revealed that all the herbicides decreased total weed density and dry weight as compared to weedy check. The herbicide proton was found to be the most effective in reducing weed population as well as weed biomass with maximum mortality compared to those other three herbicides. Proton herbicide reduced total weed density by 86% and total weed dry weight by 89%, consequently wheat grain yield was increased by 40% over weedy check.

Key words: Herbicides, Triticum aestivum, weeds, yield.
