Integrated weed management in dry-seeded rice using stale seedbeds and post sowing herbicides

Dry-seeded rice (DSR) grown with alternate wetting and drying water management (AWD) has recently been introduced in northwest India as an alternative to conventional puddled hand-transplanted rice which is labour, water and energy intensive. The aerobic seedbed of DSR can be extremely susceptible to invasion by diverse weed flora, and if weeds are not controlled effectively, yield losses can be very high. This study was undertaken to...
