Abstract: Boro rice is cultivated in waterlogged, low-lying or medium lands with irrigation facilities. It is a winter season, photo-insensitive, transplanted rice cultivated with assured irrigation and modern inputs. This gives the farmers a chance to grow a rabi season crop which normally they could not grow. Like several other modern inputs, weed management plays an important role. With the view of weed management, a field experiment was conducted during summer season of 2016 at farmer’s field of Lohagarh village, Sriniketan, India, which lies in the sub-humid and sub-tropical lateritic belt of West Bengal to study the effect of Pyriftalid + Bensulfuron methyl herbicide on transplanted summer rice. The experiment consisted of nine treatments namely Weedy Check (T1), Weed Free (T2), Pyriftalid + Bensulfuron Methyl @ 300ml/ha at 9 DAT (T3), Pyriftalid + Bensulfuron Methyl @ 375ml/ha at 9 DAT (T4), Pyriftalid + Bensulfuron Methyl @ 450ml/ha at 9 DAT (T5), Pyriftalid + Bensulfuron Methyl @ 900ml/ha at 9 DAT (T6), Pyriftalid 25% SC @ 600ml/ha at 9 DAT (T7), Bensulfuron Methyl 60% DF @ 100g/ha at 20 DAT (T8), Pretilachlor 6% + Bensulfuron 0.6% @ 10Kg/ha 3 DAT (T9) which was laid out in randomized block design with three replications.
The results showed that the application of Pyriftalid + Bensulfuron Methyl @ 450ml/ha at 9 DAT (T5), Pyriftalid + Bensulfuron Methyl @ 900ml/ha at 9 DAT (T6) were essential for improving growth attributes, yield components and productivity of summer rice. In some cases, the above treatments along with Pretilachlor 6% + Bensulfuron 0.6% @ 10Kg/ha at 3 DAT (T9) efficiently controlled the grassy and non-grassy weeds. Pyriftalid + Bensulfuron Methyl @ 450ml/ha at 9 DAT (T5) provided higher net return with high return per rupee invested. The result clearly indicated that by practicing of different weed management techniques, there was reduced infestation of weeds in summer rice and increased grain yield. The study recommends the application of Pyriftalid + Bensulfuron Methyl @ 450ml/ha at 9 DAT (T5) for good growth, higher productivity (6.18 t/ha) of summer rice.
