The Open Market Sale Scheme (OMSS) introduced by the Food Corporation of India (FCI) has had a positive impact on the sale of food grains. Here are some specific points:

• OMSS allows surplus foodgrains to be sold in the open market, helping to reduce market prices and prevent their wastage due to storage issues.
• Due to the availability of affordable food grains in the market, the demand for FCI's foodgrains has increased.
• The OMSS has also helped to reduce the government's holding costs, as the food grains can be sold quickly in the open market.
• This has allowed the FCI to transfer foodgrains from surplus-producing areas to deficit areas, ensuring food security across the country.
• The scheme has also improved the competitiveness of FCI, as it is now able to compete with private sellers in the open market.

Overall, the OMSS scheme has had a positive impact on the sale of foodgrains by FCI, allowing the corporation to effectively manage surplus food grains while reducing government holding costs.
