A field experiment was conducted during rabi season of 2013-14 to study the performance of wheat under different planting methods with varied row spacing and herbicides. Experiment was laid out in split-plot design having six planting methods [bed planting with two and three rows, drill sowing at 18 and 20 cm (conventional tillage), drill sowing at 18 and 20 cm (zero tillage)] as main-plot treatments and five herbicidal treatments [pinoxaden 50 g/ha, {carfentrazone + metsulfuron (RM)} 25 g/ha, pinoxaden + {carfentrazone + metsulfuron (RM)} (50+25g)/ha, weed free and weedy check] as subplot treatments replicated thrice. Various planting methods resulted in significant difference in population and dry matter accumulation by weeds from 60 DAS to harvest. Maximum wheat yield and minimum numbers of weeds and their lowest dry matter accumulation were observed in zero tillage, whereas, lower wheat yield and maximum number of weeds and their highest dry matter accumulation were observed in bed planting method. | Weed management studies in wheat Triticum aestivum with herbicides under different planting methods
