The government has taken several steps to combat the rising prices of rice and wheat:

• The government has declared a minimum support price (MSP) for both rice and wheat to stabilize and support farmers' income.
• The government has increased the import duty on wheat to reduce imports and encourage domestic production.
• The government has also imposed export restrictions on rice and wheat to increase the domestic supply.
• The government has increased the allocation of food subsidy to provide affordable food to the underprivileged.

The halting of the sale of rice and wheat to the states for the OMSS can have various implications:

• It can lead to a shortage of essential commodities in the market and cause an increase in prices.
• It can lead to hoarding and black marketing of rice and wheat, causing further inflation.
• It can also affect the government's stock of food grains and impact their ability to manage food security programs effectively.

Overall, the government's actions to control the prices of essential commodities and the halting of OMSS sales can have both positive and negative impacts. The effectiveness of these measures will depend on their implementation and the market dynamics prevailing in the country.
