Abstract:

An experiment was conducted in Rabi season of 2012-13 to evaluate the effect of planting techniques and herbicides on weed management and productivity of wheat. Experiment was laid out in a split-plot design, comprising five planting techniques in main-plots, viz. drill sowing at 20, 18 and 16 cm, bed planting with three and two rows; and five weed control treatments viz. pinoxaden 50 g/ha (gram/hectare), RM (ready mix) of carfentrazone + metsulfuron 25 g/ha, pinoxaden 50 g/ha with RM of carfentrazone + metsulfuron 25 g/ha, weed free and weedy check in subplot with three replications. The weed density of major weeds, total weed dry matter and nutrient uptake by weeds was significantly lower under drill sowing at 16 cm row of wheat as compared to other planting techniques. Drill sowing at 18 cm row spacing recorded significantly higher CGR (crop growth rate), grain, biological & protein yields, and nutrient uptake in grain and straw of wheat, which was statistically at par with drill sowing at 20 cm row spacing and bed planting with three rows. Tank mix application of pinoxaden (50 g/ha) and ready mix of carfentrazone + metsulfuron (25 g/ha) at 35 days after sowing was found to be effective (with weed control efficiency of 95 percent) against both type of weeds (broad leafed and grassy) with significantly lower value of weed density, weed dry matter and nutrient uptake by weed; and significantly higher value of CGR (crop growth rate), grain, biological & protein yield and nutrient uptake in wheat (grain+straw) compared to other herbicide treatments. Based on this study, 18cm row spacing was found to be optimal (to enhance productivity), and tank mix application of pinoxaden (50 g/ha) + RM of carfentrazone and metsulfuron (25 g/ha) to reduce losses due to complex weed flora in wheat.
