Alfalfa grown for forage in the arid Northwest requires 1.8-acre feet to 3.2-acre feet of water per year, depending on length of the growing season. This drought advisory publication recommends steps producers can take when water availability is reduced.
Drought is a major concern for producers of food and forage crops. According to the U.S. Drought monitor, Central and Eastern Oregon in particular, are in severe drought. In the early 1990's, a trial was conducted to determine the yield per inch of water applied to 5 cereal species: barley, triticale, rye, wheat, and oat. All varieties received the same amount of irrigation and were harvested at late boot or soft dough growth stage. These data may help producers choose a variety and species of cereal to plant as emergency forage if irrigation water is limited. (8 pages,.docx file) . .

Small fruit, vegetable and nursery crops generally require irrigation to produce the quality the market demands and the yield the producer needs. Irrigation technology has changed dramatically over the last thirty years. Independent of which system or mix of systems a grower uses, irrigation management can be challenging. An irrigation program must match the changing demands of the crop with the water supplied.
Drip Irrigation: An Introduction: Discusses the advantages of drip irrigation and how it can help growers use water efficiently.
