The state government will also buy potatoes directly from farmers at Rs.5.50 per kg and sell at Rs.7 per kg through its 20 Sufal stores (fair-price stalls) in West Bengal, said Basu."Since there is a production surplus, we are looking at exporting it to foreign countries and talks are on in this regard. To encourage businessmen to come forward for exports, a corpus fund of Rs.10 crore has been created," he said.
