Buckwheat (Fagopyrum esculentum), also known as kasha in Eastern Europe, is a pseudocereal (a crop with an end use like a cereal but is not in the grass family) that was first planted as a crop in China 5,000 to 6,000 years ago. Currently, Russia and China are the largest producers of buckwheat. Buckwheat is a minor crop in the United States where it is planted on about 27,000 acres each year. In 2017 (the most recent agricultural census when these data were collected), buckwheat was grown in more than 20 states, with the majority being grown in North Dakota, Washington, Minnesota and New York.
