Abstract
The field experiment was conducted during kharif, 2015 at Research farm, College of Agriculture, Gwalior (M.P.) to test the effect of different post emergence herbicides against grassy weeds mainly Cyperus rotundus, Dactyloctenium aeyptium, Leptochloa chinensis, and Eragrostis minor sp. in clusterbean. The experiment was laid out in “RBD” with ten treatments, replicated thrice. The treatments comprised of post–emergence grass weed killer; cycloxydim at 75, 100 and 125 g/ha with adjuvant and without adjuvant, Quizalofop-ethyl @ 37.5 g and Fenoxoprop-ethyl @ 100 g, these treatments were compared with two hand weeding at 20 and 40 DAS and weedy check. All herbicides applied at 3–4 leaf stage (around 20 DAS). Treatment T9 Weed Free check was found best by recording highest values of yield attributes, seed (2.097 tonne/ha), stover (6.568 tonne/ha) with maximum weed control efficiency at successive stages. Among different herbicides treatments, T7 Quizalofop-ethyl @ 37.5 g recorded lowest weed population/m2, weed biomass and dry weight of grassy weeds with maximum weed control efficiency at 60 DAS (85.52 %) and minimum WI (19.56) and showed highest values of yield attributes i.e 43.30 pods/plant, 8.04 seed/pods followed by T8 Fenoxoprop-ethyl @ 100 g and T4 Cycloxydim @ 75 g a.i./ha + MSO Adjuvent @ 2ml/l of water. While Treatment T6 Cycloxydim @ 125 g a.i./ha + MSO Adjuvent @ 2ml/l of water which is at par with T4 Cycloxydim @ 75 g a.i./ha + MSO Adjuvent @ 2ml/l showed minimum population of Leptochloa chinensis as compared to other treatments. In monetary terms, it may be concluded that, among different post emergence herbicides T7 Quizalofop-ethyl @ 37.5 g a.i./ha (PoE) gave significantly highest net return and B:C ratio (70597.5 Rs/ha and 5.40).
