The study is based on the result of 153 front line demonstrations carried out by ICAR-Central Research Institute for Jute and Allied Fibres, Barrackpore in North 24-Parganas district during 2017-18 and 2018-19 on mechanical weed management through CRIJAF Nail weeder. The FLD on weed management through CRIJAF nail weeder was carried out to show reduction in cost of cultivation due to less labour requirement as compared to conventional practices as well as enhancement in yield. The demonstration yield was increased by 12.11 per cent over the local check. The average extension gap, technology gap and technology index were 360.50 kg/ha, 559.50 kg/ha and 14.38 during the period under study. On an average, the demonstrated field gave higher net returns (Rs. 87337 / ha) and benefit: cost ratio (2.37) compared to the local checks. It clearly showed that adoption of improved agro-technology can boost the economics of jute growers.
