Sowing time - a tool for weed control in direct-seeded upland rice

A field experiment was conducted to find out the effect of time of sowing and weed control practices on yield and dry weight of weeds during Kharif season of 2010 and 2011 at AICRP on weed management, VNMKV, Parbhani. Sowing of direct-seeded rice (DSR) before onset of monsoon produced higher grain yields as compared to sowing after onset of monsoon. Among the different weed control methods, preemergence application of butachlor followed by one hand weeding recorded grain yields at par with weed free treatment.
