A field experiment was conducted at Meerut during rabi season 2005–2006 and 2006–2007, in a spilt plot design with four replications to find out the effect of weed management and tillage methods on wheat [Triticum aestivum (L.) emend. Fiori & Paol]. The tillage methods as main-plots treatment comprised of zero tillage, reduced tillage and conventional tillage, whereas weed control practices as sub-plot comprised of five treatments viz. sulfosulforon 25 g/ha, isoproturon 750 g + 2,4-D 250 g/ha, metribuzin 250 g/ha applied at 30 days after sowing, weed free and weedy cheek. The highest yield attributes and yield were noticed under conventional tillage followed by zero tillage. Minimum weed density and dry matter accumulation was found under zero tillage. Zero tillage was most economical. Among the methods of weed control, sulfosulfuron 25 g/ha gave excellent control of weeds and increased the yield attributes and yield, gross returns, net returns and B: C ratio. Thus zero tillage in combination with application of sulfosulfuron 25g/ha was found effective to manage weeds and increase wheat grain yield.
