Maintaining freedom from weed competition is essential in attaining full yield potential of rice crops. Ponding is an important cultural technique for suppressing the growth of highly competitive grass weeds. Aerobic rice culture (ie: with long periods of no ponding) offers the potential to improve water-use efficiency; however it provides an enhanced environment for weed growth.
This report details the results of field investigations conducted to improve the reliability of rice weed control in crops managed with aerobic drill sown culture.
Ricegrowers and agronomists who are actively seeking methods of reliable aerobic rice production will find this report of relevance to their needs.
