IMPACT OF HERBICIDE APPLICATION ON FIBRE YIELD OF JUTE ( Corchorus spp . ) IN WEST BENGAL

The present study was carried out by ICAR-Central Research Institute for Jute and Allied Fibres, Barrackpore in major jute growing districts of West Bengal to know the yield gap of jute plots with herbicidal method of weed management under frontline demonstration and manual method of weed management. It was observed that herbicidal method of weed management resulted in 8.91% more fibre yield over manual method of weeding. The extension gap was 2.43 q/ha. Adoption of herbicidal method of weed management (1.60) in jute cultivation recorded higher B: C ratio as compared to manual method of weeding (1.21). Also, net return through herbicidal method of weed management (`25,459/ha) was more than manual method of weed management (`13,564/ha). Respondents were satisfied with the performance of herbicide and wanted support from input suppliers. This experiment showed that higher profitability in jute cultivation can be achieved by the adoption of recommended herbicidal method of weed management.
