A study was made to evaluate the effect of different rates of N
fertilization on Nugaines wheat. The variable N treatments provided
different N regimes as a basis for evaluating potential diagnostic
tests for assessing the N status of the wheat plant. The crop was
grown in Lane county during...

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...
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...
An experimental environmental uptake model was developed for the purpose
of estimating the final harvest concentration of contaminant following an acute
accidental release of radiocesium onto an eastern Oregon winter wheat crop. The
system was developed using the PATHWAY environmental uptake model as
presented by Whicker and Kirchner (1987) for...
There is growing concern among producers regarding the sustainability of current dryland winter wheat cropping practices. This study looks at the economic viability of three wheat rotations currently being studied at the Columbia Basin Research Center in Pendleton, Oregon, including W IF and two alternative rotations, W/B/F and C/W/F. The...
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...
