Bernadine C. Strik
Professor, Berry Crops

Oregon has a diverse, economically important berry crop industry with about 24,000 acres harvested for a farm gate value of over $200 million. Berry crops, including blueberry, blackberry, raspberry, strawberry, cranberry, and kiwi fruit, are grown on over 1000 family farms in Oregon. Blueberry and blackberry acreage continues to grow with new growers requiring basic information on all aspects of production.

The berry crops research and statewide extension program provides outreach and engagement programs and applied research to help growers remain economically viable in this global berry market. Educational and research programs focus on methods of improving production efficiency in berry crops, particularly developing economical production systems that improve yield and quality, nutrient management, and organic production systems. In addition, I serve as the OSU lead on the USDA-ARS & OSU Cooperative berry crops breeding program, led by Dr. Chad Finn (USDA-ARS breeder at the Horticultural Crops Research Unit, Corvallis). This cooperative program started in 1917 with the objective of releasing new cultivars to benefit growers in the Pacific Northwest (PNW).

In my position (50% Extension; 35% Research; 10% Teaching; 5% Service) I conduct extension educational programs for the commercial berry crop industries (blueberries, blackberries, raspberries, strawberries, cranberries, hardy kiwifruit, and minor berries) from my campus office in the Department of Horticulture, Corvallis. In addition, I am the Berry Crops Research Leader at the North Willamette Research and Extension Center (OSU) in Aurora. My research interests focus on whole plant physiology, improving yield and quality, machine harvest efficiency, alternative production practices, plant nutrition, cold hardiness, and organic production systems. I have published many scientific articles on berry crop production and physiology and the extension publications and blueberry pruning video I have co-authored are widely distributed worldwide. I am actively involved in the International Society for Horticultural Science (ISHS) and the American Society for Horticultural Science. I was chair of the Vaccinium Section of the ISHS for 8 years and co-convened the 9th ISHS Vaccinium Symposium in Corvallis in 2008 and serve as chair of the Section for Vine and Berry Fruits of the ISHS.

Outreach and Extension

My outreach or educational programs focus on assisting the berry crop industries I work with on improving the sustainability, profitability, and production efficiency of the berry crops grown in Oregon. I reach audiences via Extension Publications, presentations to industry, 3 annual field days at the North Willamette Research and Extension Center, peer-reviewed papers available on the e-Organic web site, webinars through e-Organic, newsletter and industry trade articles, and workshops. I conduct training classes and provide educational materials for the berry crops portion of the OSU Master Gardener program.

Fun Fact

I have a "diverse" international background......I was born in Holland, lived in Australia for 6 years (as a young child) and spent my teenage and post-secondary educational years in Canada. I am now a dual USA & Canadian citizen. I was raised on a family farm and now enjoy living in the country with my family.
