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. Organic vegetable production is usually initiated in one of two ways; first is to break in virgin ground and second is to use a forage crop such as alfalfa during the transitional years. There is no market for transitional crops which limits initial production during that phase. Organic production is characterized by several challenges which are farm specific including nitrogen supply, weed control and a multitude of insect pests and diseases. Many farms would rank weed control as a major problem; for onions, it is a severe problem. Tuber worm is a new pest for organic potato producers. Variety and repellants are options for tuber worm control. We have initiated a project investigating crop rotations suited to transition to organic with a focus on nutrient management.
