A series of studies during six years examined vegetative growth and fruit yield of the 'Olympus' strawberry when grown with black polyethylene mulch and drip irrigation. In some studies, plants were grown with or without mulch and irrigated at low, medium, or high levels for one or two months in...
We have conducted a full-time program of vegetable crop research at the North Willamette Research and Extension Center (formerly the North Willamette Experiment Station) since 1976. The Center, a branch of both Oregon State University's Agricultural Experiment Station and its Extension Service, is just north of Aurora, a historic farming...
Objectives:
Breed improved Bush Blue Lake green bean varieties with:
a. White and gray mold resistance
b. Improved plant architecture
c. High economic yield
d. Improved pod quality (including straightness, color, smoothness, texture, flavor and quality retention, and delayed seed size development)
e. Tolerance to abiotic stresses
Improve seed quality...
Objectives:
Develop broccoli varieties adapted to western Oregon with suitable quality, high yields, and disease resistance. Specific traits include:
Early to midseason maturity
Concentrated yield potential
Head rot and downy mildew resistance
Large openly branched heads that are well exserted and have clean stems for easy trimming and separation into...
Though the data from the Research Evaluation does show how the new lines are doing and which crosses are the most promising, the low number of evaluators does not lead to statistically significant analysis of the results.
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...
Energy input comparisons between tillage systems; evaluation of the value of legumes as part of a cover crop mixture used in strip-till sweet corn production; evaluation of the nitrogen contribution of legume-based cover crops to organic vegetable production.
The VegNet regional pest monitoring program sponsored by the Oregon Processed Vegetable Commission has been fruitful.The program has, on occasion,saved growers money by providing
growers and agricultural professionals with early warnings
of insect pest outbreaks. The combination of regional pest
monitoring plus field scouting has allowed growers, in some cases,...
Objectives for 2009:
1. Evaluate ascospore detection of S. sclerotiorum using multiple Rotorod spore traps.
2. Monitor environmental conditions within bean fields to begin model development of ascospore detection events.
Nitrogen use varies dramatically among crops. Short season crops with relatively small
biomass accumulation will not need as much nitrogen for growth as long season corn varieties
that develop a large canopy. The recent introduction of sweet corn hybrids that tolerate root rot
may reduce N fertilizer need. Hybrids such...
This project is investigating whether low rate (goal: one pound per acre) early fall Contans applications to flailed diseased residues left on the soil surface can increase Cm inoculum and reduce Ss sclerotial viability.
Objective: Breed improved Bush Blue Lake green bean varieties with:
a. White and gray mold resistance
b. Improved plant architecture

d. Improved pod quality (including straightness, color, smoothness, texture, flavor and quality retention, and delayed seed size development)

Projects evaluated the potential of controlling hairy nightshade with tankmixes of ethofumesate and s-metolachlor and determined table beet tolerance to s-metolachlor in a commercial production system. Hairy nightshade control with Dual Magnum improved nearly linearly as the rate of Dual Magnum increased. Hairy nightshade control improved significantly when Dual Magnum...
SUMMARY
Both Impact and Laudis are effective grass killers. The weed control spectrum of these herbicides was enhanced by the addition of atrazine. Both are weak on purslane.
The data from the Stayton I experiment with Coho sweet corn suggest that corn yield may have been reduced by as much...
