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....

Evaluation and use of a soil mineralizable nitrogen test to determine the fertilizer nitrogen needs of winter wheat grown in western Oregon

Creator:: Baloch, Dost M.
Abstract:: 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...

Influence of nitrogen fertilization management on the bread making quality of different wheat genotypes

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...

Economic analysis of conservation farming systems for eastern Oregon wheat production

Creator:: Diebel, Penelope L., 1961-, Ball, Daniel A. (Daniel Allen), 1954-, and Oregon State University. Agricultural Experiment Station
Abstract:: 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...

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...

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)...

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...
