The Centre mostly procures foodgrains to be sold at subsidised rates and to maintain a buffer. Besides, it procures onions in large quantities and at times tomatoes to keep prices in check and maintain a demand-supply balance. It also sells fresh fruits, vegetables and other perishables through Safal stores under the National Dairy Development Board. Rajeev Rastogi, vice president, machine learning at Amazon, confirmed to ET the meeting held with NITI Aayog officials to get Johari deployed in government-owned centres.
