Welcome to UC Small Grains Research & Information

We are an interdisciplinary team of University of California advisors, specialists and faculty. Our purpose is to provide to growers, researchers and industry professionals agronomic guidelines and information related to the production of small grains in California.

Small Grains in California

Small grains include wheat, barley, oats and triticale. Wheat, oats and barley are grown for grain and forage while triticale is primarily grown as forage. Wheat is the predominant small grain crop in California, where it is grown on over 500,000 acres. Although relatively low in value compared to many California crops, small grains serve as important rotation crops. In most regions of the state, small grains are grown from fall through spring, thus making good use of winter rainfall and requiring relatively little irrigation.
