Abstract
An experiment was conducted at Crop Research Center of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh, India during winter seasons of 2012-13 and 2013-14 to assess the effect of seed rate and weed management practices on weeds and productivity of late sown wheat (Triticum aestivum L.) sowing with 150 kg ha-1 seed rate recorded minimum density and dry weight of weeds, which was significantly lower than 100 and 125 kg ha-1 seed rate. The minimum NPK content and uptake by weeds with 150 kg ha-1 seed rate was lower than 100 and 125 kg ha-1 seed rate, while N.P.K. content and uptake was maximum with 100 kg ha-1 seed rate. Among weed management practices minimum weed density, which was at par with Clodinafop + Metsulfuron (60 + 4 g ha-1), Fenoxaprop-p-ethyl + Metribuzin (120 + 210 g ha-1) and significantly lower than Sulfosulfuron + Metsulfuron (30 + 2 g ha-1), Sulfosulfuron 25 g ha-1 and weedy check was recorded with two hand weeding. Minimum dry matter with two hand weeding was at par with Clodinafop + Metsulfuron (60 + 4 g ha-1), Fenoxaprop-p-ethyl + Metribuzin (120 + 210 g ha-1) and significantly lower than Sulfosulfuron + Metsulfuron (30 + 2 g ha-1), Sulfosulfuron 25 g ha-1 and weedy check. Maximum NPK content and removal was recorded with weedy check, while minimum with two hand weeding which was at par with Clodinafop + Metsulfuron (60 + 4 g ha-1), Fenoxaprop-p-ethyl + Metribuzin (120 + 210 g ha-1) and Sulfosulfuron + Metsulfuron (30 + 2 g ha-1) and significantly lower than Sulfosulfuron 25 g ha-1 and weedy check.
