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...
The overall objective of this multi-year project is to maximize nutrient use efficiency without compromising bean yield and quality. This year’s project objectives were to: 1) evaluate crop response to P fertilizer at current soil P test levels in grower fields; 2) generate phosphorus (P) potassium (K), and nitrogen (N)...
Processors need broccoli with better quality traits than what is available in cultivars developed for California and Mexico fresh markets. Farmers need to reduce labor costs of broccoli production but mechanizing harvest. Most contemporary commercially available cultivars are not suitable for either mechanical harvest or processing. The objective of the...
Overview of Project and Varietal Development: Funding for 2013-14 was reduced substantially which resulted in a scaling back of the objectives. We conducted two yield and quality evaluation trials. However, the evaluation of commercial entries was funded entirely by fees from industry. We also grew out approximately 1300 breeding lines...
This research has demonstrated that liming clubroot infected soils to a pH ≥7.1 is an effective practice for reducing both the incidence and severity of clubroot. Liming does not kill the pathogen but rather prevents disease spores from infecting the plant. This research demonstrated that highly reactive calcitic lime products...
For the past 18 years, processed vegetable growers in the Willamette Valley, OR have had a vital partner in crop pest monitoring – Oregon State University’s VegNet. This regional pest monitoring program provides weekly activity reports for common broccoli, cauliflower, sweet corn, and snap bean pests. Data is published on...
Prices paid for sweet corn are low relative to the cost of producing the crop, and every strategy possible must be used to maximize net return. Two strategies used to enhance profitability but that have received little research attention under Western Oregon conditions are the use of pop-up fertilizers and...
Oregon is the second largest producer of processed green beans, and cultivars are needed that are adapted to western Oregon. The types that have traditionally been used are the bush blue lake (BBL) green beans with high yields, excellent processing quality. On the other hand, then need improvement in plant...
On April 7, 2014 the Center for Research on Lifelong STEM Learning and the Office of the Associate Provost for Academic Success and Engagement1 launched the Undergraduate Success Initiative with an invitational workshop entitled Redefining Undergraduate Success. A small planning team convened a group of 32 faculty and administrators with...
Despite the availability of several herbicides in table beets, weed control is still problematic. UpBeet (triflusulfuron; DuPont) was recently labeled, but the labeled timings and rate are inadequate for optimum weed control, particularly for lambsquarters. An experiment was placed at the OSU Vegetable Research Farm to determine the tolerance of...
