Water Use Management

The majority of California’s small grain acreage is irrigated, although rainfed grain production is also important, particularly in coastal growing areas and foothill regions of the Central Valley. The wide range of geographic locations and climate where small grains are produced determine the length of the growing season, crop water consumption, and irrigation requirements. Planned end use of the crop and stage of growth at harvest (grain or forage) also affect irrigation requirements. Recognizing and anticipating important stages of small grain growth and development is key to successfully managing irrigation.
