Wholesale potato prices in Agra, Uttar Pradesh has increased to Rs 15.25 per kg today from Rs 7 per kg in the year-ago period.
Whereas in the retail market, it is hovering in the range of Rs 30-35 per kg in the national capital.
"Export of potatoes is permitted subject to MEP of USD 360 per tonne," Directorate General of Foreign Trade (DGFT) said in a notification.
Although India was the world's second largest potato producer at 48 million tonnes in 2014-15, its exports were less than 1 per cent of the output.
