  • It is aimed at strengthening the implementation of Minimum Support Price (MSP) and ensuring remunerative prices for farmers.

Components of Pradhan Mantri Annadata Aay Sanrakshan Abhiyan

  • Price Support Scheme (PSS)
    • It ensures procurement of crops at MSP when market prices fall below MSP during harvest.
    • It mainly covers pulses, oilseeds, and copra.
    • Procurement is carried out through agencies such as the National Agricultural Cooperative Marketing Federation of India (NAFED) and the National Cooperative Consumers' Federation of India Limited (NCCF) at the request of state governments.
    • Only registered farmers with valid land records are eligible, which ensures direct benefit without intermediaries.
  • Price Stabilization Fund (PSF)
    • It protects consumers from price volatility by maintaining buffer stocks of essential commodities like pulses, onions, and potatoes.
    • It was set up to stabilize the prices of key agri-horticultural products.
    • Commodities are procured during harvest and released in lean seasons to control price spikes and ensure affordability.
  • Price Deficiency Payment Scheme (PDPS)
    • Under PDPS, farmers’ produce is not physically procured.
    • Instead, they are paid the price difference between the MSP and the actual market price in the notified market, up to 15% of the MSP value, directly into their bank accounts.
    • It is mainly used for oilseeds and reduces the need for large procurement infrastructure.
  • Market Intervention Scheme (MIS)
    • It is designed to procure a range of perishable agricultural and horticultural commodities.
