The onion, believed to be a native of Asia, has been cultivated in America since 1629. It is a major vegetable in the American diet, being used in many different ways. By value, this crop ranks in the top 10 vegetables of America. Raw onions are high in vitamin C, as well as other nutrients.
New onion varieties and hybrids produce excellent yields. Lack of water during the growing season is the major limiting factor in commercial onion production in South Dakota.
