Abstract: The field experiment was conducted to study the “Effect of herbicides combinations and hand weeding on growth, yield and weed population in transplanted rice (Oryza sativa L.)†during kharif season of 2015 at the Research Farm of Rajendra Agricultural University, Pusa, Samastipur, Bihar, India. The experiment was laid out in a Randomized Block Design with thrice replication. There were 12 treatments viz. T1 Bispyribac- Sodium 25 g/ha at 25 DAT (3-4 leaf stage), T2 Penoxsulam 24 % SC 22.5 g/ha at 15 DAT, T3 Bispyribac–Sodium+ ethoxysulfuron 25+18.75 g/ha at 25 DAT (3-4 leaf stage), T4 Bispyribac–Sodium + Chlorimuron + metsulfuron (Almix) 20 + 4 g/ha at 25 DAT (3-4 leaf stage), T5 Pretilachlor fb ethoxysulfuron 750/18.75 g/ha at 0–3 fb 25 DAT (3-4 leaf stage), T6 Pretilachlor fb Chlorimuron + metsulfuron (Almix) 750/4 g/ha at 0–3 fb 25 DAT (3-4 leaf stage), T7 Pyrazosulfuron ethyl fb Chlorimuron ethyl + metsulfuron methyl (Almix) 20/4 g/ha at 0–3 fb 25 DAT (3-4 leaf stage), T8 Penoxsulam + cyhalofop butyl 6 % OD (RM) 135 g/ha at 15–20 DAT, T9 Triafamone + ethoxysulfuron 30 % WG 60 g/ha at 15 DAT, T10 Pendimethalin (38.7 % CS) fb Bispyribac–Sodium 750/25 g/ha at 0– 3/25 DAT, T11 Hand weeding at 25 and 45 DAT and T12 Weedy check.
The results revealed that the highest growth, yield attributes, yield and low weed population of rice were recorded by treatment T11- weed free (2 hand weeding at 25 and 45 DAT). Among herbicidal treatments the highest growth yield attributes, yield and low weed population of rice were recorded by treatment T10-pendimethalin (38.7 % CS) fb bispyribac-sodium and was significantly superior to other herbicidal treatments.
