Region 3: Irrigated, Central Washington

Canola under irrigation

The ability to provide timely irrigation and fertilization to crops in central Washington greatly enhances the opportunities Washington farmers may have to produce biofuel crops. The number of biofuel crop types as well as the productivity potentials will be considerably higher and less risky for irrigated producers than dryland producers. Where irrigation water is not limiting, these crops need to compete with the high value, high yielding irrigated crops currently being grown (e.g. corn, onions, alfalfa). In the deep well district where deficit irrigation is the norm, canola has proven to be an economically viable crop in rotation with wheat, potatoes and bluegrass. More recent studies are investigating the value of irrigated winter canola as a biennial crop grown for silage and feed, as well as how to manage heavy wheat residue before planting canola.
