The resistance to white mold obtained so far in snap beans has been derived from NY 6020, which provides partial physiological resistance. Under light disease pressure, plants will show few if any symptoms, while under heavy pressure, the plants may show a moderate level of infection (whereas susceptible BBL types...
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 by mechanizing harvest. Most contemporary commercially available cultivars are not suitable for either mechanical harvest or processing. The objective of the...
The goals of this project were to determine 1) if liming controls clubroot, 2) the pH that must be attained to achieve commercially viable levels of control, and 3) how best to lime (materials, timing, incorporation strategies) to achieve that pH.
Results from vegetation management trials involving horticultural crops conducted during the past year are compiled and reported by faculty members of the Oregon Agricultural Experiment Station, the Oregon State Extension Service, and colleagues who cooperated from adjacent states along with local enterprises. This work was conducted throughout Oregon and involved...
This project is evaluating interseeding of crop crops to improve cover crop establishment after late harvested crops such as sweet corn and processing squash. In Project 1 at the OSU Vegetable Research Farm, a cover crop of oat and crimson clover produced the most cover crop biomass when interseeded at...
The overall objective of this three-year project was to provide farmers with updated fertilizer recommendations for snap beans. The goal was to maximize nutrient use efficiency without compromising bean yield and quality. This was accomplished by partnering with commercial bean growers to conduct on-farm research as well as conducting trials...
Oregon State University’s VegNet is a regional pest monitoring program that provides activity reports for 10 common insect pests that affect broccoli, cabbage, cauliflower, sweet corn, and snap beans. Crop pests are sampled weekly and raw data is compared to activity trends from previous years. Regional pest monitoring helps growers...
Urea is a common nitrogen fertilizer for sweet corn production. This two year project evaluated commercially available urea additives for their potential to provide crop production and environmental benefits. Specifically, experiments were designed to evaluate the efficacy of urea fertilizer products containing a urease inhibitor (Agrotain Ultra), or nitrification inhibitors,...
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...
Abstract— This study describes the sound produced by a
hydrokinetic turbine operating in a riverine environment near
Iguigig, AK (USA). Drifting spar buoys equipped with
hydrophones and GPS loggers were used to characterize
temporal and spatial variability in turbine sound over a range of
turbine operating conditions. Because of the...
A bad software development process leads to wasted effort and inferior products. In order to improve a software process, it is important to first understand it. Our unique approach in this paper is to use code and test changes to understand conformance to a process. We analyze the meaning of...

For each growth stage (or group of growth stages), the document lists the more effective pesticides used to control insects, weeds, and disease, their rates, and application timing for Oregon grape growers. It also covers the effectiveness of various fungicides for control...
Despite software history being indispensable for developers, there is little empirical knowledge about how they examine software history. Without such knowledge, researchers and tool builders are in danger of making wrong assumptions and building inadequate tools.
In this paper we present an in-depth empirical study about the motivations developers have...
By nature, most entrepreneurs are "doers" rather than "planners." At the same time, we know that successful organizations, regardless of their size, must plan for the future. High-level strategic planning such as establishing the long-term direction of the company is critical, but useless without a plan for implementation. This "implementation...
