摘要

A field experiment was conducted during Kharif seasons of 2015 to 2017 for three years at Agricultural Research Station; Vadgaon Maval, Pune, Maharashtra to find out the economical methods of weed control in transplanted rice. Post-emergence application of bispyribac-sodium 0.020 kg/ha (PoE) at 21 days after transplanting (DAT) followed by {fb) hand weeding at 45 DAT has effectively managed weeds in transplanted rice and produced the highest net returns (IR/s 70107/ha) with higher B:C ratio (2.3) having lower weed index (2.83) and higher weed control efficiency (87.74 %).
