The United States is the world’s second-largest producer of wheat, with 50.7 million metric tons produced in 2020. India is the world’s second-largest producer of rice, with 119.2 million metric tons produced in 2020.

Wheat is a cereal grain that is used to make bread, pasta, and other baked goods. Rice is a cereal grain that is used to make rice dishes, such as sushi and risotto. Both wheat and rice are important staple foods for people around the world.
