Development of sustainable weed management systems in direct seeded, irrigated rice. Final Technical Report.

Abstract

Successful adoption of direct seeding of rice is contingent upon weed control early in the life of the crop and the weed flora is a consequence of the method of crop establishment. A range of crop establishment and weed management methods have been tested in on-station experiments. Results clearly indicate that direct seeding in rice can give similar yields to those using conventional practices, but at a reduced cost. On-farm trials, with farmer management, also show that rice yields under direct seeding can be similar to those from transplanting and with good weed control, wet seeded rice gave the best yield. Yields of drill seeded rice however were substantially reduced where weed management was limited to one hand weeding, underlining the critical nature of weed management in direct seeded systems and the importance of chemical weed control.
