An experiment entitled Integrated Weed Management in transplanted rice (Oryza sativa L.)” was conducted at Shradhay Bhagwati Singh Agriculture Research Farm, Hajipur, Chandra Bhanu Gupta Post Graduate College, B.K.T., LUCKNOW (U.P.) during Kharif season of 2022-2023. The treatment comprised of 9 weed management practices. Weedy check till maturity, Weed free upto 60 DAT, Pretilachlor 50 % EC @ 1.25 kg a.i/ha (PE), Pendimethaline 30 % EC @1.0 kg a.i/ha (PE), Pendimethaline 30 % EC @ 1.0 kg a.i/ha + 1 hand weeding at 30DAT, Pendimethaline 30 % EC @1.0 kg a.i/ha (PE) + Bispyribac Sodium 10 % SC @ 25 g a.i/ha (POE), Pretilachlor 50 % EC @1.0 kg a.i/ha + 1 hand weeding At 35DAT, Two hand weeding at 20 and 40 DAT, Pretilachlor 5 0 % E C @ 1.0 kg a.i/ha (PE) + Bispyribac sodium 10% SC @ 25 g a.i/ha (POE). Weed free up to 60 DAT resulted in significantly higher growth, yield attributes and yield over result of the treatments. The highest weed control efficiency was recorded with weed free up to 60 DAT. However, the highest weed Index was recorded with weedy check and lowest being with weed free up to 60 DAT. The highest net returns (Rs. 58, 218.31/ha) was recorded by weed free up to 60 DAT and highest B:C ratio was recorded by Pretilachlor 50 % E C @ 1.0 kg a.i/ha (PE) + Bispyribac Sodium 10% SC @ 25 g a.i/ha (POE).
