Abstract: An investigation was conducted at College of Agriculture, Nagpur to study the effect of Weed management in drilled paddy (Oryza sativa L.) during kharif season of 2014-2015. The experiment was laid down in Randomized block design having treatments viz., Control (T1), 2 hand weeding at 20 and 40 DAS (T2), Butachlor @ 1500 g a.i. ha-1 at 7 DAS (T3), Pretilachlor @ 750g a.i. ha-1 at 7 DAS (T4), 2, 4 D @ 1000 g a.i. ha-1 at 20 - 25 DAS (T5), Pyrazosulfuron ethyl @ 25 g a.i. ha-1 at 20 - 25 DAS (T6), Butachlor @ 1500 g a.i. ha-1 at 7 DAS + 2, 4 D @ 1000 g a.i.ha-1 at 20 - 25 DAS(T7), Butachlor @ 1500 g a.i. ha-1 at 7 DAS + Pyrazosulfuron ethyl @ 25 g a.i.ha-1 at 20 - 25 DAS (T8), Pretilachlor @ 750 g a.i. ha-1 at 7 DAS + 2, 4 D @ 1000 g a.i. ha-1 at 20 - 25 DAS (T9), Pretilachlor @ 750 g a.i. ha-1 at 7 DAS + Pyrazosulfuron ethyl @ 25 g a.i.ha-1 at 20 - 25 DAS (T10) thereby making Ten treatment combinations replicated three times. Rice variety PKV- Khamang was used as a test crop. Results showed that 2 hand weeding at 20 and 40 DAS (T2) significantly influenced the growth and yield attributing characters viz., Height of plant (cm), Number of effective tillers hill-1, Number of panicles hill-1, Number of grains panicle-1, Test weight (g), Yield of grains hill-1 (g), Yield of straw hill-1 (g), Yield of grains (q ha-1), Yield of straw (q ha-1), and Harvest index (%) and it was at par with treatments (T7), (T8), (T9), (T10).
