Abstract:
Rice (Oryza sativa L.) is one of the staple food crops for more than half of global population and is mostly grown as transplanted crop. Recently, there has been a shift from transplanting to direct-seeding due to scarcity of water and labour. The transition towards direct seeded rice saves water, reduces duration to maturity as well as labour required. But weeds pose a serious threat in direct seeded rice compared to transplanting due to alternate wetting and drying. Thus, the success of direct seeded rice depends on effective weed management. Though manual weeding is the best but due to higher labour requirement, there is a need to use herbicide but the use of herbicides alone does not provide effective and sustainable weed control. Therefore, there is a need to integrate herbicide with alternate weed management approaches or pre-emergence herbicide followed by a post-emergence herbicide for effective weed management in direct seeded rice. In this review, we examine the extent of weed infestation, losses in direct seeded rice and earlier work on different weed management approaches in direct seeded rice.
