A field experiment was carried out at Department of Agronomy, Anbil Dharmalingam Agricultural College and Research Institute, Trichy during Rabi, 2018 to study the effect of different weed management practices on yield attributes and yield of transplanted rice. The experiment was laid out in split plot design with four main plot and five sub plot treatments and replicated thrice. The experimental plot size was 20 m². Main plot treatments were pre plant application of herbicides namely, glyphosate 2.5 kg ha^-1, glufosinate ammonium 1.0 kg ha^-1,halosulfuron methyl 67.5 g ha^-1 and control. Sub plot treatments consisted of different weed management practices in transplanted rice namely, pre emergence application of bensulfuron methyl + pretilachlor 660 g ha^-1 on 3 DAT + one hand weeding on 45 DAT, post emergence application of bispyribac sodium 25 g ha^-1 on 15 DAT + one hand weeding on 45 DAT, application of bensulfuron methyl + pretilachlor 660 g ha^-1 on 3 DAT + bispyribac sodium 25 g ha^-1 on 25 DAT, hand weeding twice at 25 and 45 DAT and unweeded control. Pre plant herbicides sprayed 15 days before puddling. The rice variety TRY 3 was grown during the course of investigation. Pre plant application of glyphosate 2.5 kg ha^-1 recorded significantly higher yield attributes and yield viz., productive tillers (350 m^-2), Panicle length (24.4 cm), filled grains (153 panicle^-1), total grains (171 panicle^-1), higher grain yield (4232 kg ha^-1), straw yield (6986 kg ha^-1) and harvest index (0.38 %) than halosulfuron methyl and control. These results are closely followed by glufosinate ammonium 1.0 kg ha^-1. Among the weed management practices fallowed in transplanted rice, post emergence application of bispyribac sodium 25 g ha^-1 + hand weeding on 45 DAT registered significantly higher yield attributes and yield Viz., productive tillers (338 m^-2), Panicle length (24.7 cm), filled grains (159 panicle^-1), total grains (179 panicle^-1), higher grain yield (4327 kg ha^-1) and harvest index (0.39 %) than others. Pre emergence application of bensulfuron methyl + pretilachlor 660 g ha^-1 + post emergence application of bispyribac sodium 25 g ha^-1 on 25 DAT significantly registered higher straw yield of 7174 kg ha^-1over unweeded control.
