The dryland cereal producer in the lower Columbia Basin makes many critical soil and crop management decisions each season. These decisions are made more difficult because of the highly variable climatic conditions that exist in the region. A particularly difficult crop management decision facing the cereal grower is the determination...
The septoria diseases of winter wheat are a limiting factor to wheat production in the Willamette Valley. This publication will describe the symptoms and development of the septoria diseases, including the influence of environmental conditions, the reactions of different cultivars to Septoria, the impact of Septoria on yield, and control...

In a series of 30 winter wheat fertilizer experiments conducted in the Willamette Valley between 1963 and 1969, optimum rates of nitrogen fertilization varied from 75 to 150 pounds per acre. Fertilization with N, particularly at the-higher rates, increased the protein content of the grain.
Spring-applied N gave greater yield...
Proper nitrogen (N) management and variety selection are important for profitable hard red winter (HRW) wheat production in the dryland growing regions of northeastern Oregon. In these dryland systems, N management for grain yield and grain protein concentration (GPC) is challenging due to climatic and year-to-year variation in production environments....
‘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.
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...
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...
Hard white winter (HVVW) wheat cultivars must have superior protein quality and consistent processing quality to be successful in the Asian market. New cultivars and management strategies are needed to produce HVVW grain for both bread and noodle applications from diverse environments in the US Pacific Northwest (PNW). This study...
