Effect of crop establishment methods and weed management practices on productivity, soil properties and economics of wheat under rice – wheat cropping system

Afield experiment was conducted at the Crop Research Centre of GBPUA& T, Pantnagar, Udham Singh Nagar continuous two years to study the productivity, soil properties,andeconomicsofwheat(Triticum aestivum L.) under different wheat establishment methods in main plots and seven weed management practices in sub plots, replicated thrice in a split plot design. Zero tilled wheat exhibited more -2 number of spikes mand more number of grains per spike was significantly higher than reduced and conventional tillage. The zero tilled wheat yielded 12.35 and 3.66 per cent higher over reduced and conventional sttillage during I year and 11.99 and 3.09 per nd cent during IIyear. The bulk density of soil was higher under zero tillage than that of othertillage.Theinfiltrationratewassignificantly greater with ZT than RT and CT. The highest grain yield was obtained in two hand weedings done at 30 and 60 DAS -1and was at par with Isoproturon 1.0 kg ha+ -1Metsulfuron methyl 4 g haat 30DAS and -1Clodinafop – Propargyl 60 g haat 30 DAS -1fb. Metsulfuron methyl 4 g haat 37 DAS
