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...

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...
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...
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)...
The assessment of optimum nitrogen (N) fertilizer need for winter wheat (Triticum
aestivum L.) is important for economic and environmental sustainability. A comprehensive understanding of fertilizer N requirement depends on estimation of the quantity of N needed by the crop versus that supplied by soil.
The objectives of this study...
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...
