Project Started
Breeding Vegetables for Organic Systems

We are in the second year of three years of funding for organic breeding. The three breeding projects (late blight resistant tomatoes, bush tromboncino summer squash, OP broccoli) will extend beyond the timeframe of the grant with the earliest expectation of release being with broccoli materials in 2007. The tomato and summer squash projects have another seven years or so before we will see the first variety release.

Integrating Beetle Habitat into Pacific Northwest Farming Systems

Why care about Beetles?

Cover Crops and Conservation Tillage Systems

Conservation tillage methods been widely adopted for agronomic crop production but because they rely on herbicide use, organic vegetable growers have not adopted them. Legume cover crops offer the opportunity to capture N from the atmosphere through symbiotic fixation in the root nodules and possibly produce N at a lower cost. We are investigating cover crop mixtures and mechanical kill methods to maximize benefits in organic vegetable production systems.

Weed Management and High Residue Reduced Tillage

Evaluating Meadowfoam as a Pesticide in Dryland Organic Wheat Production

Weed Management in Organic Strawberry Production

Organic mulches, cultivation, mustard seed meal, and vinegar have been evaluated for weed suppression in organic strawberry production systems.

Intensive Protective Cultivation of Bi-color Sweet Cherries using Light Spectral Management

The goal of this project to identify those ecological soil community management strategies which synchronize soil nutrient availability with tree demand in order to improve long-term farm health, fruit quality, and production.


Irrigated Production in Eastern Oregon

Organic production in Eastern Oregon has started to grow as a portion of the acreage on historically conventional farms. Organic vegetable production is well suited to the Lower Umatilla Basin because of the favorable climate and quality irrigation water. Vegetables (potatoes, onions, peas, corn and carrots) have the potential to be rotated with a forage crop such as alfalfa or other legumes such as winter peas. These forages could be used for organic feeds throughout the Pacific Northwest.

Management of Soils for Soil-Borne Disease Suppression

As rotations shorten and fumigants become scarce there is increasing grower and researcher interest in the development of alternative strategies for soil-borne disease management.

Nutrient and Pest Management in High Value Organic Agriculture

Nick Andrews is developing an applied research and extension program in organic vegetable production at the North Willamette Research and Extension Center (NWREC) in Aurora. NWREC is in the process of transitioning about 3.5 acres to organic production.
