About this variety
Bidhan Kusum is a suran (elephant foot yam) variety developed by Bidhan Chandra Krishi Viswavidyalaya (BCKV), Kalyani, West Bengal, through selection, for the eastern plains. Sources describe it as a high-yielding type with smooth corms and creamy flesh, with a reported yield of about 50–55 t/ha. Its duration and disease reaction are not documented in the sources checked, and sources differ on acridity — some list it as non-acrid, others as acrid — so it is sensible to plant a small lot first and taste-test a properly cooked corm before scaling up. Ask BCKV or your KVK whether they can supply planting material or point you to a grower.
