Abstract: A field experiment was conducted in machine transplanted rice crop at Agricultural Research Institute, Rajendranagar, Hyderabad during kharif, 2019 to study the efficacy of different herbicides, herbicide mixtures and to identify efficient weed management option for machine transplanted rice. Weed management practices significantly influenced the growth parameters, yield attributes and yield of machine transplanted rice crop. Hand weeding at 20, 40 DAT recorded significantly higher growth parameters like plant height, tillers, leaf area index, dry matter production and was at par with penoxsulam 1.02% W/W + cyhalofop-p-butyl 5.1% W/W @ 153 g ha-1 at 2-3 leaf stage of weeds + power weeder at 30-40 DAT. Hand weeding at 20, 40 DAT noticed significantly increased yield attributes, grain yield (6.92 t ha-1) and at par with penoxsulam 1.02% W/W + cyhalofop-p-butyl 5.1% W/W @ 153 g ha-1 at 2-3 leaf stage of weeds + power weeder at 30-40 DAT (6.73 t ha-1). Weedy check recorded lowest grain yield among all treatments (3.79 t ha-1).
