Production

Cereals are the world's largest crops by tonnage of grain produced. Three cereals, maize, wheat, and rice, together accounted for 89% of all cereal production worldwide in 2012, and 43% of the global supply of food energy in 2009, while the production of oats and rye has drastically fallen from their 1960s levels.

Other cereals not included in the U.N.'s Food and Agriculture Organization statistics include wild rice, which is grown in small amounts in North America, and teff, an ancient grain that is a staple in Ethiopia. Teff is grown in sub-Saharan Africa as a grass primarily for feeding horses. It is high in fiber and protein. Its flour is often used to make injera. It can be eaten as a warm breakfast cereal like farina with a chocolate or nutty flavor.

The table shows the annual production of cereals in 1961, 1980, 2000, 2010, and 2019/2020.
