A field experiment was carried out at Jute Research Station, Katihar, Bihar to study the effect of integrated weed management practices on growth, yield and economics of tossa jute. The experiment was taken up with eight treatments comprising: use of butachlor with different formulations (50% EC and 5% granules) and dosages of (1.0 kg and 1.5 kg/ha), pretilachlor 1.0 kg/ha as pre-emergence application (PE) followed by (fb) one hand weeding (HW) at 20 days after emergence of crop (DAE), quizalofop-ethyl 60 g/ha + sticker 1 ml/ l as post-emergence application (PoE) at 15 DAE fb one HW at 35 DAE and other treatments include hand weeding twice at 15 and 35 DAE and weedy check. A randomized block design with three replications was used. Amongst tested weed control treatments, quizalofop-ethyl 60g/ha PoE at 15 DAE fb one hand weeding at 35 DAE was found effective in significantly increasing the plant height, basal diameter and fibre yield of jute over weedy check and was economical compared to hand weeding twice.
