Recently, we hosted a Willamette Valley Vegetable Education Day at NWREC. The link includes slides from our presenters on a variety of topics including pest management, irrigation, and cover crop selection.
For more field days and workshops, check out the NWREC Events calendar and the College of Agricultural Sciences Field Days calendar.
Introduction
Introduction
Muskmelon production in the Willamette Valley is usually limited by cool springs, a short growing season, and relatively cool nights, even during mid-summer. Cultural techniques to increase air and soil temperature around plants, such as black plastic mulch and row covers, have hastened development and increased yield of muskmelon in the valley.

Introduction
Objectives: 1. Breed Bush Blue Lake green bean varieties with high economic yield and improved plant architecture. 2. Improve pod characteristics including straightness, color, smoothness, texture, flavor and quality retention, and combine with delayed seed size development. 3. Incorporate white mold resistance and improve root rot tolerance. 4. Map genes for resistance to white mold to facilitate marker aided selection.
Organic Seed Alliance recently released an extensive report that serves as the first comprehensive analysis of the challenges and opportunities in building the organic seed sector. The report, titled State of Organic Seed: Advancing the Viability and Integrity of Organic Seed Systems, is an ongoing project to monitor the status of organic seed systems in the United States.

Introduction
Overwintered vegetables, seeded in late summer or early autumn for harvest the following spring, are important new alternative crops in the Willamette Valley. These crops offer a source of cash flow in the spring, present the opportunity for three crops in two years, and may be less expensive to grow because of reduced needs for insecticides and irrigation. Cauliflower, onions, and spinach have shown the most promise as overwintered crops.

Introduction
Tomato and muskmelon production in the Willamette Valley is limited by cool springs, a short growing season, and relatively cool nights, even during mid-summer. Cultural techniques to increase the mean air and soil temperatures around plants, such as plastic mulch and row covers, have hastened development and increased yield of both crops.

Objectives:
The first "really" purple variety to come from a program at OSU.
Aphid populations are being monitored in 4 different red table beet plantings in the South Willamette Valley. Fields were
selected because of their proximity to sugar beets being grown for seed. Yellow pan traps with water are being used to monitor black bean aphid and green peach aphid flights into beets. Aphid populations are being monitored on beets for in field build up.

There is an increasing interest among Oregon vegetable producers in the use of cover crops to improve soil quality, provide biologically fixed nitrogen to reduce fertilizer inputs, and reduce ground water contamination. Because of the cost associated with cover crop establishment and spring incorporation ($25-40/acre), the ability to account for N contribution from the cover crop and reduce fertilizer inputs could help offset the cover crop costs.

Objectives: 1. Breed Bush Blue Lake green bean varieties with high economic yield and improved plant architecture. 2. Improve pod characteristics including straightness, color, smoothness, texture, flavor and quality retention, and combine with delayed seed size development. 3. Incorporate white mold resistance and improve root rot tolerance. 4. Develop a molecular marker map to facilitate marker-assisted selection of desirable horticultural traits.

Objective: Identify sweet corn hybrids released for the processing market for high and stable yields under heavy and light root rot pressure.
Jim Myers describes common problems in the garden
The purpose of these trials was to evaluate varieties of cauliflower for summer harvest. The major desired quality is heat tolerance: the ability to withstand high temperatures without ricing and to maintain the high curd quality typical of autumn-harvested cauliflower. A second desired quality is long wrapper leaves for self-blanching.
Objectives:
The Willamette Valley of western Oregon is well known for production of a wide range of quality vegetables. Commercial, large-scale production of warm-weather vegetables such as tomatoes and melons is possible but is limited by competition from more favorable growing areas. However, for the home gardener or small market gardener, production of almost any vegetable crop except tropicals is possible in the long, mild growing season of the Willamette Valley. Major limiting factors are late spring frosts, insufficient heat for some warm-weather crops, and low night temperatures.

Objectives:
Enhanced efficiency fertilizer (EEF) technologies have the potential to improve the crop N use efficiency (NUE) as well as minimize negative environmental losses compared to conventional fertilizers. The EEF fertilizer products consist of urea plus additives (to inhibit N loss). The major pathways for N loss in our sweet corn cropping systems are 1) N leached below the root zone as water soluble nitrate-N (NO3-N), and 2) gaseous ammonia loss (NH3-N) to the atmosphere following a surface urea application.Field studies and a laboratory incubation study were conducted in 2014 to evaluate the potential for benefit from EEF products via reduced nitrate-N leaching. Three products were evaluated: ESN (polymer coated urea), SuperU (prilled urea containing both a urease and nitrification inhibitor), and Instinct (urea + nitrification inhibitor).

Introduction
The justification for this trial is similar to that for cauliflower, reported earlier. A sweet corn trial in 1992 indicated that source and placement of nitrogen fertilizer had little effect on yield or quality of sweet corn. Rates of nitrogen application greater than 60 pounds per acre resulted in accumulation of significant amounts of nitrate-N in the soil. The purpose of these trials was to confirm 1992 results and to determine if yield of sweet corn would be affected by source or timing of application of nitrogen fertilizer.

VegNet is a regional pest monitoring and reporting network serving the Oregon processed vegetable industry, managed by the OSU Extension Service, and funded by the Oregon Processed Vegetable Commission. In the early spring of 2012, thirty six insect monitoring stations were established on cooperating farms located strategically throughout the Willamette Basin and maintained during the growing season.
The goals of the VegNet Regional Pest Monitoring and Reporting System are:
