The document discusses various concepts related to agricultural prices, including:
- Minimum support prices (MSP) which aim to protect farmers from steep price declines. 
- Procurement prices which are slightly higher than MSP and used by the government to purchase crops from farmers.
- Issue prices which are the prices at which the government sells commodities to consumers through public distribution systems.
- The role of the Agricultural Prices Commission in recommending MSPs and other price policies to the government.
