Processed vegetable farmers and processors have taken leadership in developing and implementing sustainability practices.

April 1, 1986

This was the fourth and last of the series of variety trials and focused on mid-maturity varieties to determine those with the best combination of yield and quality. The previous trials had established that the best quality is obtained with varieties maturing in April and early May.

The trial was seeded on July 27, and transplanted on September 3, 1982. On February 16, 1983, 35 pounds N/acre as ammonium sulfate, 40 pounds N/acre as calcium nitrate, and 100 pounds/acre of 0-45-0 was sidedressed. An additional 75 pounds N/acre as ammonium nitrate was applied on March 14.

Higher yields and improved root quality are essential for processing carrot growers to remain competitive. Nitrogen fertilizer applications range from 50 to 150 pounds N/acre with most between 50 and 80 pounds. More research is needed to clarify yield response to nitrogen, especially at higher rates, and the influence of N on such root characteristics as diameter, length, splitting, and rots. The response to N should be investigated at plant densities typically used for slicing and dicing.

Overwintered vegetable crops, planted in July through October and harvested the following spring, offer several advantages to both fresh market and traditional row crop growers.

Overwintered cauliflower trials at the North Willamette Station and by growers have usually given acceptable yields and quality. However, yields of early varieties, and particularly in cold springs, have occasionally been disappointing. Since plant nutrient uptake is limited on cold soils, these low yields may have been caused by inadequate availability of P or other elements.

Weed management in table beets has improved with the recent registration of Dual Magnum. Hairy nightshade control continues to be a challenge, however. Nortron (ethofumesate) herbicide is now labeled for use and will help with nightshade control, but there is very little experience in the PNW on the best use patterns for this herbicide. Another concern is carryover, particularly for fresh market producers that often plant another crop immediately after beets are harvested.

1. Varieties.
Winter cauliflower varieties require a cold period to induce head formation. The heads, or curd, of overwintering cauliflower are composed of true flower buds and are usually of lower density than for Snowball types in which the curd is floral primordia tissue. Stems often tend to be slightly green and flavor tends to be mild. Because of the low density and tendency to break up when the stem is removed, these varieties are considered more promising for fresh market than for processing.

Introduction

This grower trial was undertaken to determine whether residual nitrate and ammonium levels in grower fields were similar to those found in our experiments at NWREC. The data should be useful in indicating which of the major processed vegetable crops leave significant quantities of residual mineral N in the soil at harvest and the extent to which grower cultural practices, particularly fertilizer application, influence the amount of residual N that is available for leaching by heavy winter rainfall.

Poor stand establishment is often a limiting factor in vegetable production in the Willamette Valley. Carrots, onions, and lettuce, in particular, often fail to emerge because of soil crusting. Most small-seeded crops lack the vigor necessary to emerge when resisted by significant soil impedance. A high degree of impedance or crusting (also known as soil mechanical resistance) is caused by breakdown of soil particle aggregates. Several treatments exist which may reduce the breakdown of aggregates.

The purpose of these experiments was to determine the effect of a commercial cytokinin preparation on yield and quality of several Willamette Valley horticultural crops. Atlantic and Pacific Research, Inc. manufactures a marine algae extract, containing 100 ppm kinetin, which has increased fruit and vegetable yields in several areas of the country and is registered for use on tomatoes. This product, Cytex, is stable and can be applied with standard spray equipment.

As a result of the variety and planting date trials described above, overwintered cauliflower is now considered a crop of proven potential in the Willamette Valley. Trials at the North Willamette Station and by growers have usually given acceptable yields and quality. However, yields of early varieties, and particularly in cold springs, have occasionally been disappointing. Since plant nutrient uptake is limited on cold soils, these low yields may have been caused by inadequate availability of P or other elements.

This report summarizes the third year of research to improve management of cabbage maggot. The cabbage maggot, Delia radicum, is a chronic pest problem in Willamette Valley cauliflower. Current management of this pest relies exclusively on prophylactic chemical applications; usually with Lorsban. This study has included investigation of cabbage maggot life cycles, evaluation of treatment practices and evaluation of sampling techniques for making management decisions.

With the creation of this Oregon Conservation Strategy, by the Oregon Department of Fish and Wildlife, Oregon has its first overarching state strategy for conserving fish and wildlife. The Conservation Strategy is an effort to use the best available science to create a broad vision and conceptual framework for long-term conservation of Oregon’s native fish and wildlife, as well as various invertebrates and native plants.The Oregon Conservation Strategy provides information about at-risk species and habitats, identifies key issues affecting wildlife and recommends specific actions.

The Resource Innovation Group announces the release of Toward a Resilient Watershed: Addressing Climate Change Planning in Watershed Assessments. The guidebook is intended to complement or supplement a watershed assessment process by posing questions of how climate change will impact the structure and function of the watershed. The guidebook helps watershed managers understand how future climate scenarios could affect their management decisions and identifies proactive measures to improve the resilience of stream habitat and water quality.

Food-borne illness linked to pathogens in meat, processed food, and produce has led to increased attention to food safety issues at all points along the supply chain, including the farm. Farmers can produce safe food without sacrificing responsible on-farm conservation measures, such as maintaining riparian habitat or other non-crop vegetation. By using risk assessment strategies and explaining their rationale for management decisions to include conservation measures, farmers can more effectively advocate for their farming practices with buyers and food safety auditors.

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.
