By
value, onions rank in the top 10 vegetables produced in the United States.
They are believed to be indigenous to Asia and have been cultivated in
this country since 1629. Flexibility of the onion in the American diet
is the main reason it is used so extensively in the United States.
The principal market outlet for U.S. dry onion production is the fresh
market, but the processed market, including frozen, canned, onion rings
and dehydrated products, is also important.
Approximately 75 percent of the total annual onion production is marketed
through the fresh market.
