Summary

Since 1992, the Oregon State University Malheur Agricultural Experiment Station in Ontario, Oregon, has evaluated drip irrigation on onion. As pioneers in onion drip irrigation, we have investigated crop response to irrigation intensity and flow rate, bed configuration, subsurface chemigation, nitrogen fertilizer rates, microirrigation criteria, and plant population.
