This publication describes results of applied research on phosphorus fertilization of late-planted winter wheat in no-till fallow in the low-precipitation zone of Oregon and Washington.
A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...
‘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.
Douglas-fir (Psudotsuga menziesii (Mirb.) Franco) seedlings were outplanted on eight dates (every three weeks from mid-August 2005 through mid-January 2006). On each plant date, seedlings from a conventional dormancy (CONV) induction treatment, including moisture and nutrient stress, and a shortened daylength (SD) treatment were outplanted on three western Oregon sites...

Norwest 553 is a common hard red winter wheat variety developed by Oregon State University and Nickerson U.K. in cooperation with USDA-ARS. It is an awned, short-statured, semidwarf variety with high-yield potential and good milling and baking quality. Norwest 553 is resistant to stripe rust and tolerant to Fusarium crown...
I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...
Over the past half century, the USDA Forest Service has increasingly faced
diverse and often competing demands for forest resources, ranging from recreation,
to ecosystem services, and timber supply. Building positive community-agency
relationships has become increasingly important. Such relationships can improve
community support for forest planning and management activities, ultimately...
