Dr. Asesh Kumar Ghorai

Principal Scientist & In-Charge


Integrated weed management of jute using different approaches like cultural (smothering by green gram and high density jute sowing), chemical (by different herbicides) and mechanical means (using CRIJAF Nail Weeder and CRIJAF Herbicide applicator). Dissemination of technologies on jute green and gram (1:1) and intercropping, and use of gunny bags for vegetable production in anaerobic rice field to increase land productivity, farmers’ income, improving water productivity and improve soil health. I am also engaged in dissemination of drought management technologies on jute and mesta and its insitu retting in low volume water and composting of farm wastes to avoid GHG emission by technics developed at ICAR-CRIJAF with the help of Deptt. of Agril.Govt. of WB.
