Fertilizer experiments with winter wheat in western Oregon

Creator:: Roberts, Steve, 1930-, Gardner, Ernest Hugh, Kronstad, Warren E. (Warren Evrind), 1932-, Goetze, Norman R. (Norman Richard), Murarka, Ishwar P., 1942-, and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: 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...

Using the nitrogen mineralization soil test to predict spring fertilizer N rate : soft white winter wheat grown in western Oregon

Creator:: Oregon State University. Extension Service, Hart, John M. (John Mervyn), 1947-, Christensen, Neil Walter, 1944-, Mellbye, Mark Edward, and Flowers, Michael Darrell, 1971-
Abstract:: 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...

A climate-yield-nitrogen computer program to evaluate wheat fertilizer strategies for optimal nitrogen application for winter wheat production in North Central Oregon

Creator:: Bolton, Floyd E., Miller, Stanley F., Taylor, Mike, and Glenn, D. Michael
Abstract:: 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...

Nitrogen available to winter wheat as influenced by previous crop in a moist xeric environment

Creator:: Qureshi, Maqsood Hassan
Abstract:: Rotating wheat with other crops is a common practice in the Willamette Valley of western Oregon. Depending upon previous crop and soil type, current N fertilizer recommendations for wheat in the Willamette Valley vary widely. Excessive fertilizer poses environmental risk, whereas lower N inputs than required by the crop represent...

Long-term effects of tillage, nitrogen, and rainfall on winter wheat yields

Creator:: Camara, Kelli Marie
Abstract:: Winter wheat is commonly grown in dryland cropping systems in the Pacific Northwest region of semi-arid eastern Oregon. For agronomic, economic, and environmental reasons, it is important to understand the long-term sustainability of such dryland systems. The objective of this study was to evaluate the long-term effects of tillage, nitrogen...

Nitrogen timing and placement effects on grain and plant nitrogen, and grain yield in hard red winter wheat

Creator:: Bohle, Mylen G.
Abstract:: Hard red winter wheat has the potential to be an alternative crop in the Pacific Northwest, however percent grain nitrogen has been unacceptably low and grain yields have been about only 80% of soft white winter wheat. During the late spring and the summer months there is usually little rainfall,...
