California is big source in U.S. onion production
California is a big force in the U.S. onion market.
According to a report from University of California, Davis, California is the largest onion producer (including fresh and processed) in the U.S. and is the only state to produce both spring and summer-harvested onions.
In 2015, the report said California produced 31% of the nation’s total onion crop.
About 16% of California onions are spring harvested, and the state produces 42% of the nation’s spring harvested onion crop.
About half of California onions are grown for the fresh market, and about half for processing, according to the report.
The proportion of spring, summer, fresh and processing onions tends to be stable, according to the report.
Onions are grown throughout California.
In a recent census, the counties with the top onion acreage were Fresno, Imperial, Kern, Siskiyou, and San Joaquin, with over a third of the state’s acreage located in Fresno County, according to the report.
The high desert region of Antelope Valley in Los Angeles County and the Salinas Valley also include some fresh market onion acreage, the report said.
