Paddy is one of the imperative cereal crops of state Jharkhand and plays a crucial part in the economy. Paddy yield is drastically influenced by weeds infestation resulting decrease in output and productivity. The experiment was conducted at Chhotakipona village, Chitarpur Block, Ramgarh, Jharkhand during kharif season of 2018 using Randomised Block Design with 9 weed control methods T1- Weedy check, T2- Pretilachlore @ 0.75 kgha-1 as pre-emergence, T3- Pretilachlore@0.75 kgha-1 + Bispyribac Na@25gha-1, T4- Pendimethalin @ 1 kgha-1 + 2,4-D @ 1.00 kgha-1 at 30 DAS, T5- Pendimethalin @ 1 kgha-1 as pre-emergence + Bispyribac Na @ 25 gha-1, T6- Bispyribac Na @ 25 gha-1 as post-emergence at 20 DAS, T7- Hand weeding at 20 DAS + Hoeing at 40 DAS, T8- Two hand weeding at 20 & 40 DAS and T9- weed free and replicated 3 times. The hand weeding and hoeing were carried out manually. Application of IWM (Integrated weed management) in paddy Pretilachlore@0.75 kgha-1 + Bispyribac Na@25gha-1 was recorded maximum yield attributes resulting in higher grain yield (4952 kgha-1).
