History of Agronomy at the University of California

Letter A in vintage font type
In 1904, a Division of Experimental Agronomy was established in the College of Agriculture of the University of California, Berkeley. By 1906, it was clear that a Berkeley location for experimental work could not meet requirements and the division was shifted to the University Farm at Davis. more

Agronomy is the application of science and technology from the fields of biology, chemistry, economics, ecology, soil science, water science, pest management and genetics to the improvement and management of the major food crops of the world. more

alfalfa leaves, close-up image


Alfalfa production occurs over about 1,000,000 acres throughout California, with the highest-producing regions in Imperial County and the San Joaquin Valley.

variety of dried beans with bags and scoops


California farmers grow mainly four classes of dry beans — limas (99% of U.S. supply), common beans, garbanzos, and cowpeas — on about 50,000 total acres.

canola bloom close-up


Imported corn and sorghum are currently used to produce bio-fuel in California. However, canola, camelina, sugar beets, and sorghum offer promise as a basis for in-state production.

corn stalks on plant


Corn is grown on nearly 600,000 acres in California, primarily in the Central Valley. It is mainly used for silage and grain, with a small specialty crop market comprised of sweet corn, corn nuts and popcorn.

cotton bolls on plant


Uses for cotton fibers range from heavy industrial to fine fabrics. California cotton grows mainly in the San Joaquin Valley on 200,000 to 300,000 acres.

safflower bloom on plant

Oil Seeds

Safflower is the primary oil seed grown for oil in California. Sunflower hydrid seeds are grown and exported for oil production. Canola and camelina are showing promise as new oil seed crops.

rice grains on plant


California rice is grown primarily in the Sacramento Valley on approximately 550,000 total acres. Mostly high quality medium grain rice is produced as well as some other specialty rice varieties.

wheat stalks on plant

Small Grains

Small grains are an important rotation crop in California and include wheat, barley, oats and triticale planted on over 800,000 acres. Wheat is the predominant California small grain crop.

Sorghum plant


Sorghum is being rediscovered as a valuable rotational crop and forage that can help California meet future water needs, specialty food markets, and potentially as a renewable fuel crop.

sugar beets

Sugar Beets

California sugar beet production began in 1870 and beets have been produced in nearly all agricultural areas. Beets are now grown only on about 25,000 acres in the Imperial Valley.
