ABSTRACT
The experiment was conducted to study the efficacy of different pre and post emergence herbicides in cotton (Gossypium hirsutum L.). Highly significant differences (P< 0.01) were observed among the treatments for weed density, bolls per plant and seed cotton yield, while differences among the treatments of plant height and boll weight were significant at 5 % level of probability. The lowest weed flora was recorded in hand weeded plots which was statistically equal with Pendimethalin [Stomp 330 E (Full Dose)], Oxadiazon (Ronstar 25 EC) and Fenoxaprop. Maximum weed population was recorded in the weedy check. In chemical weed control measures, Stomp 330 E (F.D) exhibited the best control of weeds (93.18 %). Hand weeding produced maximum bolls per plant (38) and seed cotton yield of 2168 kg ha -1, and was statistically at par with pre-emergence herbicides viz; Stomp 330 E (F.D), Ronstar 25 EC and Treflan 5 EC.
