Description A field experiment entitled “Effect of planting techniques and herbicides on weed management and productivity in wheat” was conducted during Rabi 2012-13 at Agronomy Research Farm of CCS Haryana Agricultural University, Hisar. The experiment comprised of five planting techniques viz. drill sowing at 16, 18 and 20 cm and bed planting with two and three rows in main plots and five weed control treatments viz. Pinoxaden (50 g/ha at 35 DAS), Carfentrazone+ Metsulfuron (RM) 25 g/ha at 35 DAS, pinoxaden+ [carfentrazone+metsulfuron (RM)] 50+25 g/ha at 35 DAS, weed free, weedy check in sub plots. The experiment was laid out in split-plot design with three replications. Based on research investigation it was found that major weed in field were P. minor, C. album, A. arvensis and M. indica. Planting techniques had no significant effect on weed count and weed dry matter at 30 DAS. Density and dry matter of weeds from 60 DAS to harvest were significantly low in 16 cm row spacing than other planting techniques. Planting techniques had no significant effect on plant height, whereas, dry matter accumulation and leaf area index were significantly higher in 18 cm, 20 cm and three row bed planting. Drill sowing at 18 cm row spacing produced significantly higher tillers, whereas, two row bed planting has significantly longer spike length and 1000 grain weight. The grain, straw, biological and protein yield were significantly higher in 18 cm, 20 cm and three row bed planting methods. Planting techniques as well as weed control treatments had no significant effect on quality parameters and NPK content in weeds and crop. However, nutrient uptake by weeds was low in 16 cm row spacing, whereas, uptake by crop was higher in 18 cm, 20 cm and three rows bed planting. Gross and net returns and B:C were maximum under 18 cm row spacing.
Tank mix application of pinoxaden (50 g/ha) and ready mix of carfentrazone+metsulfuron (25 g/ha) at 35 DAS efficiently controlled grassy as well as broad leaved weeds with WCE of 84.3 and 95.5 per cent, respectively. However, alone application of pinoxaden and carfentrazone+metsulfuron (RM) controlled grassy and broad leaved weeds, respectively. Their combined application gave significantly higher values of growth parameters, yield attributes, yields, protein yield, nutrient uptake and economics returns by wheat and lower nutrient uptake by weeds as compared to weedy check but was at par with weed free.
