News and Events

Ag Tech Field Day is a new event for 2025! Hosted at OSU's North Willamette Research and Extension Center in Aurora, OR, the event will showcase research trials, demonstrations, and discussions about emerging technology applications for farms in our region. Join us on June 12th, 2025. The link provides details on presenters and topics and the station locations can be seen on this map. 

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.

Effect of N Source on Yield of Overwintered Onions, 1984-1985
February 1, 1987

In the N source trial, the number of bulbs harvested per plot varied significantly with treatment, but the stands may have varied before the treatments were applied (Table 4). Total yield varied with N source, but the differences were not directly proportional to stand differences. Mean bulb weight and percent No. 1 bulbs were greatest with ammonium sulfate, in spite of a greater than average stand. They were lowest with ammonium chloride, in spite of a low stand. The high percentage of No.

Overwintered Onion Weed Control Trial, 1985-1986
February 1, 1987

The major cultural problem in overwintered onion production is weed control. Onions are a slow-growing crop which competes poorly with weeds. Since the crop is in the ground for eight or nine months, and cultivation is nearly impossible during the winter rainy season, both good weed control at planting and good postemergence control are necessary. The weed control task has been made more difficult by the loss of registration of effective preemergence herbicides such as propachlor.

Overwinter Leek Variety Trial, 1984-1985
February 1, 1987

Extremely high quality leeks are being produced on a small scale in the Willamette Valley with good yields. The crop is usually seeded in early spring, matures in autumn, and can be held through the winter for harvest the following spring. Very few varieties are grown commercially and the highest quality plants have been transplanted and grown in trench culture. The most lucrative market is the restaurant trade, which demands long, thick, blanched stems. Healthy foliage can also be used decoratively in presentation of restaurant dishes.

Management of Sweet Corn Root and Crown Rot in the Pacific Northwest
December 31, 2005

Objective 1: Evaluation commercial sweet corn varieties in small plots for susceptibility to seed rot/damping-off as well as crown rot.

Evaluation of Fungicides for the Control of Gray and White Mold in Snap Beans
December 14, 2005

Cancellation of the registration of an effective bean mold fungicide, Ronilan, is slated to occur at the end of growing season in 2005. Finding equivalent alternatives by 2006 for use in snap bean is critical. The goal of the project is to continue evaluations of alternative fungicides for their effectiveness in controlling Gray Mold (Botrytis cinerea) and White Mold (Sclerotinia sclerotiorum) on snap bean using Ronilan as the industry standard.

Cultivar evaluation for control of common smut in sweet corn in the Columbia Basin of Oregon and Washington
December 31, 2008

Twenty-five sweet corn cultivars were evaluated for resistance to natural infection by common smut.

Identification of high yielding, root rot tolerant sweet corn hybrids
December 31, 2007

Objective: Identify sweet corn hybrids released for the processing market for high and stable yields under heavy and light root rot pressure.

VegNet regional pest monitoring program
December 31, 2007

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 2007, a variety of insect traps were placed on cooperating farms in vegetable production areas around the Willamette Basin and maintained during the growing season.

Identification of High Yielding, Root Rot Tolerant Sweet Corn Hybrids
December 31, 2006

Three trials at two locations were conducted to evaluate sweet corn hybrids for performance under root rot conditions. While both sugar/se and supersweet sweet corn hybrids were evaluated, the emphasis was again on identifying supersweet hybrids with improved tolerance to root rot.

Evaluation of Fungicides for the Control of Gray and White Mold in Snap Beans
December 31, 2006

Cancellation of the registration of an effective bean mold fungicide, Ronilan, occurred at the end of the 2005 growing season. Finding equivalent alternatives for use in snap bean is critical. The goal of the project is to continue evaluations of alternative fungicides for their effectiveness in controlling white mold (Sclerotinia sclerotiorum) and gray mold (Botrytis cinerea) on snap bean.

Processing and quality evaluation of experimental green beans: Supplemental report
December 31, 2009

Fifty-three preliminary OSU breeding lines along with Savannah, 91G, OR54, OSU 5630, and OSU 5669 as checks were processed in the 2009 OSU Preliminary Breeding Trial. In the Commercial Trial, seventeen commercial selections were processed along with four checks:. OR 91G, OR 54, OSU 5630, and OSU 6443.

Management of Fusarium diseases of sweet corn in the Pacific Northwest
December 31, 2009

Objective 1: Evaluate sweet corn inbred germplasm for colonization of silks by Fusarium species and subsequent seed infection/contamination. Objective 2: Evaluate biological applications to silks and subsequent Fusarium presence in ears. Objective 3: Evaluate seed disinfestation and location of remaining Fusarium on or in seed. Objective 4: Examine the yield and disease levels of sweet corn plants grown from seeds treated with germicidal light.

Identification of High Yielding, Root Rot Tolerant Sweet Corn Hybrids
December 31, 2005

Objective: Identify sweet corn hybrids released for the processing market for high and stable yields under heavy and light root rot pressure.
