Narendra Modi today suggested a"five F" formula to the farmers of country's cotton growing areas which he claimed will ensure remunerative prices for cotton growers and give fillip to apparel export. "Cotton sector in country should follow 'five F' formula. Farm to fibre to fabric to fashion to foreign," he said, while addressing a rally in favour of SAD candidates for Lok Sabha polls here. Bathinda is one of the major cotton growing areas in Punjab. Modi said that he had invented 'five F' formula after cotton growers in Gujarat had to suffer financial loss of Rs 7,000 crore when export of cotton was halted by the Centre. "They (Congress led UPA) caused a loss of Rs 7,000 crore to Gujarat farmers when export of cotton was stopped without any reason," he claimed. Punjab's cotton growers have also been complaining of getting less prices for their crop. Punjab grows cotton at an area over five lakh hectares per annum.
