Abstract: Poor weed management practices is one of the severe barrier to enhance productivity of wheat. Today high yield agriculture relies on herbicides, as integral part of weed control practices The experiment treatments were divided into horizontal and vertical plots in strip plot design with three replications. The horizontal plots were divided into six weed management practices and vertical plots were divided into three tillage practices. The treatments comprised of unweeded control (W1), pendimethalin @ 1.0 kg ha-1 as pre-emergence (PE)(W2), sulfosulfuron@25gha-1 as post-emergence(PoE) (W3), pendimethalin@1.0 kg ha-1 (PE) followed by sulfosulfuron @ 25g ha-1 (PoE) (W4), hand weeding at 30 DAS (W5) and black polythene mulch (W6) in horizontal plot under weed management practices and conventional tillage (T1), minimum tillage (T2) and zero tillage (T3) in vertical plots under tillage management practices. The application of pendimethalin @ 1.0 kg ha-1 (PE) followed by sulfosulfuron @ 25 g ha-1 (PoE) was found to be statistically superior over all the treatment except hand weding at 30 DAS at the same level of convetional tillage during both the years. The convetional tillage was found to be statistically superior over minmum and zero tillage at the same level of the application of pendimethalin @ 1.0 kg ha-1 (PE) followed by sulfosulfuron @ 25 g ha-1 (PoE) during both the years.
