Abstract:
Transplanting rice seedlings in puddled conditions is the major rice cultivation system in many parts of the world. The transplanting system provides a high and stable yield. It is labour-intensive and requires around 1500-2000 mm of irrigation water (1500-2000 mm). A decrease in irrigation water and labour availability forced the farmers to adopt a direct seeding system, especially in Asian countries where rice is a staple crop. Wet direct seeding of rice cultivation saves the amount on labour expenditure but it has very low water-saving potential. Dry direct seeding is another rice establishment method that has the potential to save both water and labour. Seedling raising, puddling, and transplanting of seedlings are omitted in the dry direct seeding system, weed infestation is one of the major constraints responsible for poor productivity in direct-seeded rice, especially in dry direct seeding (Singh et al., 2006). Strategies for weed management in direct-seeded rice depend on the critical period of weed control, weed flora, and the method adopted. The sole application of pre or post-emergence herbicides does not provide effective control over weeds as compared to a combination of pre and post-emergence herbicides in rice (Walia et al., 2008). As a long-term goal to achieve sustainable management of weeds in Direct seeded rice (DSR) an integration of different weed management methods stale seedbed, mulch and integrated weed management (IWM) are essential.
