A field experiment was conducted at Parbhani on vertisols during rabi seasons of 2013-14 and 2014-15 to find out the effect of eight weed control strategies i.e. T1: Pendimethalin @ 0.75 kg/ ha (PE), T 2: Trifluralin @ 1.0 kg/ ha (PE), T 3: Metolachlor 0.75 kg/ ha (PE), T 4: Imazethapyr @ 0.75 kg/ ha (POE), T 5: Quizalofop ethyl @ 40 g/ ha (POE), T 6: Propaquizafop @ 0.75 kg/ ha (POE), T 7: Weed free and T 8: Weedy check were evaluated in randomized block design with three replications. The predominant weed flora were Brachiria eruciformis, Chenopodium album, and Cynodon dactylon L. among monocost; Cyperus rotundus L. among sedges; and Amaranthus viridis L., Digera arvensis, Portulaca oleracea, Physalis minima, Euphorbia hirta, Parthenium hysterrophorus and Alternenthara sessili among dicots. The significantly lowest dry weight of weeds and highest WCE, grain, bhoosa and biological yield was observed in Pendimethalin @ 0.75 kg ha-1 (PE), and it was significantly superior over rest of the treatments. Weedy check recorded lowest grain and bhoosa yield. Among the chemical weed control treatments, The application of Pendimethalin 0.75 kg/ ha (PE) recorded beneficial higher grain, bhoosa yield, WCE, highest net monetary returns and B.C. ratio and it was found most economical and effective in controlling weeds and increasing the yield of chickpea.
