Rice (Oryza sativa) is the major food crop in terms of production, economy and grown in all ecological regions. In Asia, particularly in the tropical regions, transplanting is the predominant method of rice establishment. This method is highly input and water intensive, raising concerns about long-term sustainability. Climate change, especially in the form of water scarcity, poses a significant threat to traditional rice cultivation. Direct-Seeded Rice (DSR) has emerged as a viable and resource-efficient alternative to the traditional puddled transplanted rice (TPR) system, particularly in the context of increasing labour scarcity, water limitations and the need for sustainable agricultural practices. DSR bypasses nursery raising and transplanting, allowing rice seeds to be sown directly in the main field. This approach significantly reduces water usage, labour demand and greenhouse gas emissions, while enhancing soil health and profitability. Precise water management, particularly during crop emergence phase (first 7-15 days after sowing), is crucial in direct seeded rice. Furthermore, weed infestation is the major problem, which can cause large yield losses in direct seeded rice. Weed management in DSR can be done through chemical, hand weeding or stale seed bed method.
