We have conducted a full-time program of vegetable crop research at the North Willamette Research and Extension Center (formerly the North Willamette Experiment Station) since 1976. The Center, a branch of both the Oregon State University Agricultural Experiment Station and Extension Service, is just north of Aurora, a historic farming community 20 miles south of Portland, Oregon. The land is provided by Clackamas County, with facilities owned and maintained by OSU. The Center serves the vegetable, small fruit, wine grape, and nursery crops industries and is located in an area noted for the diversity of its agriculture. Our vegetable research emphasizes the needs of both the fresh market and processed vegetable growers in the Willamette Valley. We also conduct research on home garden and small farm intensive vegetable culture. Many of the research projects reported here involved cooperation with Experiment Station and Extension Service colleagues at Oregon State University. Their contributions are gratefully acknowledged. The financial support of the Oregon Processed Vegetable Commission, UNOCAL, Biagro Western Sales, and the Agricultural Research Foundation was essential to completing these projects and is greatly appreciated. This report is the tenth in a series of biennial reports initiated in 1979.
