Successful Onion Irrigation Scheduling

Clint Shock, E. Feibert, Lynn Jensen and, Jim Klauzer (September, 2010)

Summary

Irrigation scheduling is directly related to profitable onion production and sustainable agricultural practices. Research at the Oregon State University Malheur Experiment Station has demonstrated that onion yield and grade are very closely related to irrigation practices, especially the criterion used to schedule irrigations. Careful attention to irrigation scheduling can help assure high onion yields, better bulb storability, and better internal quality. Small errors in irrigation can result in large losses in yield, especially in marketable yield of the larger size class bulbs.
