Nitrogen management and variety selection for dryland production of hard red winter wheat in northeastern Oregon

Creator:

Jepsen, Daniel R.

Abstract:

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....

Post-accident radiocesium uptake in eastern Oregon wheat crops : A preliminary estimate using a modified "PATHWAY" model

Creator:

Palotay, Joshua A.

Abstract:

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...

Environmental constraints on the use of anion exchange membranes in dryland wheat

Creator:

Redman, Andrea Elizabeth

Abstract:

Lack of growing season precipitation and the temperate climate in north central Oregon pose challenges to growing spring wheat crops. Phosphate and sulfate fertilization can improve early growth of spring wheat in this region and soil testing aids in determining rates of fertilization. In this study, anion exchange membranes (AEM)...
