Introduction

Phosphorus pollution of the Willamette River and its tributaries is a problem affecting agriculture in western Oregon. Many of our soils are high in available (soluble) P, as measured by the tests commonly used to determine plant-availability of P. Consequently, many streams have background levels of P that are conducive to algal blooms and poor water quality for fisheries and recreational use. Agriculture may also contribute to P pollution of streams through the use of large amounts of phosphate fertilizers and is under pressure to reduce P applications.

 A network of local weather stations may provide the processed vegetable industry with more accurate weather forecasts. Local weather data may enhance our ability to predict crop developmental stages, insect pest population trends, and disease high-risk periods.

Objectives:

  • To establish, maintain, and evaluate an on-farm weather station for use in crop development, disease and insect pest population forecasting.

 This project focuses on developing and evaluating strip-tillage vegetable production systems which integrate winter-annual cover crops. Goals include increasing farm income and enhancing soil and water quality. A new strip-till machine using chisel plows and rolling fluted coulters was tested in seven on-farm, paired comparisons with conventional "grower practice" tillage for sweet corn production.

Introduction

Higher yields and improved root quality are essential for processing carrot growers to remain competitive. Nitrogen fertilizer applications usually range from 50 to 100 pounds N/acre with most between 50 and 80 pounds. More research is needed to clarify yield response to N, especially at higher rates, and the influence of N on such root characteristics as diameter, length, splitting, and rots. Yield response to application of banded P fertilizer is also poorly understood.

For bean production in the Willamette Valley, perhaps one of the most obvious objectives is resistance to white mold (Sclerotinia) since this pathogen is difficult to control using chemicals and no native resistance has been found in common bean (Phaseolus vulgaris). It has been shown that the production of oxalic acid by the fungus Sclerotinia is the primary cause of pathogenicity. If the oxalic acid can be degraded rapidly by the plant, the symptoms of infection can be inhibited.
