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....

Creator:: Derényi, Marina Castro
Abstract:: Breadmaking quality is an important criterion in breeding and development of hard wheat (Triticum aestivum L.) cultivars. Improvements in N management are needed to produce superior quality grain and satisfy market demands for protein content. Field experiments with three hard red and two hard white spring wheat cultivars were conducted...

Full Text:: . Levels of nitrogen. N fertilizer may have as much, or more, marked effect on wheat quality parameters

Creator:: Laopirojana, Pojanee
Abstract:: 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...

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...

Full Text:: , 2006. Title: Post-Accident Radiocesium Uptake in Eastern Oregon Wheat Crops: A Preliminary Estimate

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...

Full Text:: the dryland wheat-fallow systems of north-central Oregon and eastern Washington. ASSESSMENT OF PLANT

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)...
