Patit Paban De, senior member of the West Bengal Cold Storage Association, said there will be an estimated 10 per cent lower production of tubers, given the trend and reports of loading of crops in cold storages. "Till now, loading is only between 70-75 per cent on average. At the maximum, loading will not cross 80 per cent at best given the trend. Last year loading was 88-89 per cent," he said.
