The study of wheat (Triticum aestivum L.) as it relates to end-use quality is highly diverse. This dissertation examines end-use quality across the U.S. and how the non-starch polysaccharide arabinoxylan (AX) influences ...

Nutrient cycling is an important matter in all crop production but it is particularly important in oilseed production. The efficiency by which oilseed crops can be grown and the impact of their cultivation dictates the ...

Smallholder farmers in southeastern Africa are constrained by poor rainwater-use efficiency, soil degradation, and limited financial resources. Conservation agriculture (CA), based on the principles of minimal soil ...

Small grains are grown in rotation with many temperate crops in the Columbia Basin and Puget Sound regions, functioning to improve the profitability of the cash crops. During 2009-10, 45 isolates of

Switchgrass (Panicum virgatum L.) is a perennial warm-season grass that has been selected as an important lignocellulosic feedstock to support bioenergy production. Intercropping of two perennial species, switchgrass and ...

In pyrolysis, an alternative to petroleum-based energy, the result of low oxygen combustion is a carbon-rich solid commonly called biochar. We evaluated biochars made from four feedstocks regionally available (wood pellets ...

Statistical analysis has many applications ensuring the validity and reproducibility of plant breeding and genetics research. Crop plant germplasm collections are often too large to be of use regularly. A core subset with ...

Winter wheat (Triticum aestivum) is currently grown in crop rotations in western Washington to break disease cycles and improve soil quality. There is interest in creating a local grain system to add value to the crop. Two ...

Continual application of ammoniacal sources of nitrogen fertilizer can result in decreased bulk soil pH. Many soils of the Columbia Basin (CB), Washington State are weakly buffered and therefore susceptible to acidification. ...

Increased nitrogen (N) fertilizer additions to modern agricultural cropping systems will be necessary to feed a growing world population. However, greater nitrogen use efficiency (NUE) is required if agroecosystems are to ...
