The field experiment was conducted duringkharif, 2022 to evaluate the effect of different post emergence herbicides on growth and yield of rice (Oryza sativa L.) at Agronomy Farm, College of Agriculture, Dapoli, District Ratnagiri (M.S.).The experiment was laid out in a randomized block design with ten treatments which were replicated three times viz., (T1) Pyribenzoxim 3% + Penoxsulam 2% EC @ 500 ml ha-1, (T2) Pyribenzoxim 3% + Penoxsulam 2% EC @ 750 ml ha-1, (T3) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1000 ml ha-1, (T4) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha-1, (T5) Pyribenzoxim 5% EC @ 600 ml ha-1, (T6) Penoxsulam 2.67% OD @ 1000 ml ha-1, (T7) Bispyribac-Sodium 20% + Pyrazosulfuron Ethyl 15% WDG @ 100 g ha-1, (T8) Triafamone 20% +Ethoxysulfuron 10% WG @ 225 g ha-1, (T9) Hand weeding at 30 and 60 DAT and (T10) Weedy check (Untreated). The results of the experiment showed that the application of post emergence herbicide Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha-1 has positive effect on growth and yield of rice.Significantly higher values of growth attributes such as plant height (cm),number of tillers hill-1, dry matter accumulation hill-1 (g) were observed with treatment (T4) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha-1 at 60, 90 and 120 DAT and at harvest stage as compared to other treatments whereas, least values were recorded with treatment (T10) Weedy check. Significantly higher grain yield (4050.55 kg ha-1) and straw yield (5524.62 kg ha-1) was observed with treatment (T4) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha-1 and lower grain and straw yield was observed with treatment (T10) Weedy check.
