Effect of weed management and seed rate on crop growth under direct dry seeded rice systems in Bangladesh.
Weeds are a major constraint to the success of dry-seeded rice (DSR).The main means of managing these in a DSR system is through chemical weed control using herbicides.However, the use of herbicides alone may not be sustainable in the long term.Approaches that aim for high crop competitiveness therefore need to be exploited.One such approach is the
