Soft white winter wheat grown in western Oregon requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers because wheat is produced in numerous rotations that provide varying amounts of N to the wheat crop. Inadequate...
This publication describes results of field research on the performance of hard red winter wheat cultivars in a late-planted no-till fallow system in the low-precipitation zone of Oregon and Washington.
The successful production of hard wheat with acceptable protein is based, in part, on an effective nitrogen (N) management plan. This fact sheet discusses the principles of managing N
for hard wheat production and explains how to calculate an N application rate. The information contained in this fact
sheet is...

The hemlock woolly adelgid, Adelges tsugae, is causing widespread mortality of eastern hemlock, Tsuga canadensis, in the eastern United States. In the West, A. tsugae causes negligible damage to western hemlock, Tsuga heterophylla. Host tolerance traits and presence of endemic predators may be contributing to the relative tolerance of western...
This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...
Soft white winter wheat is grown in western Oregon and requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers. Wheat obtains N from two sources: soil and fertilizer. Both available and mineralizable N can be...
'Tubbs' is a soft white winter wheat variety developed by Oregon State University in cooperation with the USDA Agricultural Research Service. This publication describes the agronomic characteristics, development, and availability of Tubbs.
‘Skiles’ is a common soft white winter wheat developed by Oregon State University in cooperation with the USDA Agricultural Research Service. This publication describes the variety, its agronomic characteristics, development, and seed availability.
'Tubbs 06' is a soft white winter wheat variety developed by Oregon State University in cooperation with the USDA Agricultural Research Service. This publication describes the agronomic characteristics, development, and availability of Tubbs 06.
‘ORCF-103’ is a common soft white winter wheat developed by Oregon State University in cooperation with the USDA Agricultural Research Service. This publication describes the variety, its agronomic characteristics, development, and seed availability.
This guide provides nutrient and lime recommendations for establishment of turf and forage perennial ryegrass grown for seed in western Oregon. Healthy plants with adequate root systems are required to obtain the greatest return from your fertilizer investment. The nutrient recommendations in this guide assume that adequate control of weeds,...
Gives nutrient and lime recommendations for soft white winter wheat in western Oregon. Also discusses: impact of diseases, such as take-all root rot, on crop yield; planting in poorly drained soil; soils and settings for wheat production; fall and spring nutrient management; and postharvest evaluation of nitrogen. Includes sources of...

Hemlock woolly adelgid, Adelges tsugae Annand, is a destructive introduced pest of hemlock trees in eastern North America, and management has focused on the use of natural enemies through classical biological control. Two species of chamaemyiid flies, Leucopis argenticollis Zetterstedt and Leucopis atrifacies (Aldrich) have been collected previously from western...

The purpose of the study was to determine whether Adult Basic Education/General Educational Development students and Developmental Education students are significantly different in selected basic skills and in selected personality characteristics. The population of the study (N=100) consisted of equal numbers of students enrolled in ABE/GED and DE classes at...
Nursery plants are often harvested, stored, and shipped bare-root for easier and more economical handling. Some species of woody and herbaceous perennials are less tolerant of postharvest handling than others. Desiccation stress during the handling of bare-root plants has been identified as a major problem contributing to poor survival and...
The Columbia River Gillnetter is the pilot of the Lower Columbia River commercial fishing industry, keeping fishermen and the public in touch with today's important issues.
Larval mortality of leafcutting bee, Megachile pacifica (Panzer)
(= rotundata (F.)), is high, usually exceeding 50%. Parasites and
predators are not a limiting factor in the survival of the progeny.
The disease chalk brood has been an important mortality factor since
1974. Inadequate food supply, pollen and nectar, may affect...
It was the intent of this investigation to compare the performance
of community college students to four-year institutional students, both
of whom were enrolled in a college general biology program (GS 101,
102, 103) during the 1967-68 academic year. During the week of
May 27, 1968 measurements were taken of...
The Forest Service and the Bureau of Land Management propose to adopt coordinated ecosystem management direction for the lands they administer within the range of the northern spotted owl. This Supplemental Environmental Impact Statement (SETS) presents as alternatives the options, with slight modifications, developed by the Forest Ecosystem Management Assessment...
The climate of the Pacific Northwest is in flux, and existing forest ecosystems are stressed and poised to shift in fundamental ways, with or without human intervention. This dissertation probes the nature of forest responses to environmental change through investigations of morphology and genetics of three species of alder co-occurring...

The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...
