Field experiment was conducted to find out the effectiveness of eleven weed control treatments including weedy check in soybean. Propaquizafop 50g + imazethapyr 100 g/ha on 20 DAS was as effective as hand weeding twice in reducing the population of E. colona, Commelina banghalensis, Cyperus iria, Ageratum conyzoides and Polygonum alatum. Propaquizafop alone was not effective against A. conyzoides and P. alatum. Application of propaquizafop 75 g/ha on 15 or 25 DAS significantly enhanced the number of branches per plant, pods/plant, 1000-seed weight and seed yield of soybean. Combined tank-mix application of propaquizafop + imazethapyr, propaquizafop + chlorimuron ethyl and quizalofop ethyl + chlorimuron ethyl had more branches/plant, seeds/pod, 1000-seed weight and seed yield than other chemical treatments. These combinations were comparable to hand weeding in influencing yield attributes and seed yield of soybean.
