Rice-wheat system has started showing the signs of fatigue. Certain reports say that the wheat yield reduces by 8% when sown after puddled transplanted rice compared to wheat sown after direct-seeded rice. The conventional method of wheat sowing by repeated tillage delays the sowing by 10 to 15 days, which adversely affect yield. To curtail problems faced by intensive tillage in rice and delayed sowing of wheat, adoption of no or reduced tillage is a viable option. The high input requirement and less competitive nature of high yielding dwarf wheat varieties have provided conducive environment for weed infestation. The average yield losses caused by weeds in different wheat growingzones ranged from 20 to 32%. Uncontrolled weeds in wheat caused 60.5% reduction in wheat grain yield under CT and 70% in ZT conditions. Potential solutions include a shift from intensive tillage to no or reduced tillage and/or from transplanting to direct-seeding. Zero tillage ameliorates the problem of delayed sowing as well as reduces weeds like Phalaris minor in wheat. A shift from an intensive tillage to reduced/no tillage system cause major changes in weed dynamics, herbicide efficacy and weed seedrecruitment. Therefore, an attempt has been made in this article to review works done on several aspects of weed management in zero-till wheat. 收起
