Around 12-16 salt-resistant varieties are being extensively researched in field trials in the Sunderbans, including one termed 'Dudheswar'. Elaborating on the procedure of harvesting this new variety, Majumdar said, "The special variety of seed has been harvested in agricultural land in coastal areas which were inundated with saline water due to flood during cyclones Amphan and Yaas. We pumped out the water to reduce the high salinity levels after the natural calamity and then the seeds were sown.” Since the water could not be pumped out from all the fields, elevated plots were chosen for sowing the seeds of 'Nona Swarna', he said.
