Abstract

Rice–wheat cropping is an effective use of land to maximise yields of vital cereal crops in India. However, the cropping system is facing constraints in part related to combining two crops with different growth habits and requirements. This project built on previous work to promote the adoption of direct-seeded rice, combined with appropriate weed management, to rice–wheat farmers on the Gangetic Plains of India. Field trials demonstrated that yields in direct-seeded rice can be comparable with those in transplanted systems. In the absence of weed control there is a significant reduction in yields under direct seeding, but this can be minimised with appropriate weed-management. The use of a herbicide followed by a single hand-weeding conferred a significant benefit in comparison with hand-weeding alone. The research has shown that changes in composition of the weed flora occurred under different direct-seeded crop establishment – information important to future weed-management strategies. Shortages of labour and water, coupled with the incentive for many farmers to reduce overall input costs, are likely to result in widespread adoption of direct seeding in many parts of the Gangetic Plains. The need to control weeds to protect yields will be paramount, and this project has laid a sound basis for the development and promotion of appropriate weed-management practices
