Chhattisgarh is known as the “Rice Bowl of India” due to its significant production of rice. Rice is the staple food of India and is grown in most parts of the country. However, Chhattisgarh is one of the leading producers of rice in India. In 2020-21, Chhattisgarh produced 11.5 million tonnes of rice, which was about 10% of the total production of rice in India.
Wheat is another important crop grown in Chhattisgarh. In 2020-21, Chhattisgarh produced 4.5 million tonnes of wheat, which was about 4% of the total production of wheat in India.
Maize is also grown in Chhattisgarh, but it is not as important as rice or wheat. In 2020-21, Chhattisgarh produced 1.5 million tonnes of maize, which was about 1% of the total production of maize in India.
Sugarcane is not grown in Chhattisgarh in significant quantities. In 2020-21, Chhattisgarh produced 0.5 million tonnes of sugarcane, which was about 0.1% of the total production of sugarcane in India.
Therefore, the correct answer to the question is rice.
