We have innovated the Onion storage ventilators , which has high scalability, which helps to limit the price fluctuation of crop , benefits the farmers by providing them as much as double the value of there crop , as during harvesting of the crop the price goes very down approx 200 -300 rupees/ quintal , due to lack of storage facility for farmers , the same crop after storage for 3 months gives the value of 7-8 rupees . Also due to lack of storage there comes a time of accute shortage and high gap between demand and supply that results in price hike. Onion is a necessity in every kitchen. Thus by implementing our technique there will be huge difference for farmers in revenue generation and also there would be no severe hike in prices that effects the common man.
