The zero till wheat crop sown after direct seeded puddled rice, recorded significantly higher dry matter accumulation by Phalaris minor as compared to conventionally sown wheat crop. However, the seed bank sbtus was not affected due to tillage systems. Zero till sown crop recorded significantly less grain yield than conventionally tilled crop. On an average of three years, highest wheat grain yield (3843" kg ha") was obtained in conventionally tilled wheat after transplanted rice and it was significantly more than that of zero tilled wheat after rice with or without puddling. Clodinafop at 60 g. sulfosulfuron at 25 g and fenoxaprop-p-ethyl at 100 g ha-' increased wheat grain yield by 41.9•. 43.7 and 39.9%. respectively. over weedy crop.
