Research and Extension
The Orchard Crops Extension Program is based out of the North Willamette Research and Extension Center in Aurora, OR. Our research is focused on developing best management practices for growing hazelnut and fruit tree in the Willamette Valley, and educating growers in the areas of orchard management, production, and pest control.
- Hazelnuts and Nut Crops
- Fruit Trees
The North Willamette Research and Extension Center is home to the Orchard Crops Research and Extension Program led by Dr. Nik Wiman, which has a mandate to provide applied research and Extension for the Oregon hazelnut industry. We work closely with the industry to help solve problems related to hazelnut production. This includes research on insect pests (including the invasive Brown Marmorated Stink Bug, (BMSB) and beneficials, nutrient management, irrigation management, and emerging disease issues. We also work with other orchard crops including peaches, almonds and cider apples. We offer a number of workshops in any given year covering topics such as pruning, pest management, and cover crops.
