Impacts of nitrogen fertility, soilborne disease, and socioeconomic factors on diverse small grain production systems of the Pacific Northwest
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
Rotational Cropping Systems for Nitrogen Management and Weed Control in Dryland Organic Wheat Production
Diversification of cropping systems with legumes is a common practice used to overcome soil fertility and weed control challenges in organic farming systems. The current study assessed different legume-intensive cropping ...
EFFECTS OF GENOTYPE, FERTILIZER, AND MYCORRHIZAL FUNGI ON PHOSPHORUS USE EFFICIENCY OF ORGANIC AND CONVENTIONAL SPRING WHEAT
Recent attention to the increasing environmental and monetary costs of mining dwindling phosphorus (P) reserves have lead to renewed efforts to design agricultural systems that use P more efficiently. The objective of these ...
Statistical Applications in Plant Breeding and Genetics
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 ...
Characterization of glyphosate-resistant mechanism(s) in spring wheat (Triticum aestivum L.) induced through mutagenesis
Wheat susceptibility to glyphosate, a non-selective herbicide targeting the EPSPS enzyme, encouraged the development of glyphosate-resistant (GR) spring wheat through mutation breeding using ethyl methanesulfonate (EMS) ...
Genetics of drought tolerance in common bean (Phaseolus vulgaris L.)
Drought is a major constraint limiting dry bean (Phaseolus vulgaris L.) yield worldwide. Some lines express tolerance but the mechanisms are not well understood. We sought to: i) identify quantitative trait loci (QTL) ...
Sustainable Intercropping of Switchgrass and Hybrid Poplar for Bioenergy Production
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 ...
INVESTIGATIONS INTO PRACTICAL APPLICATIONS FOR THE CRITICAL WATER ACTIVITY FROM DYNAMIC DEWPOINT ISOTHERMS
Moisture plays an important role in the stability and storability of grain and grain based products. Stability factors such as microbial growth and texture are impacted by moisture and are well correlated to water activity, ...
Agronomic and Sociological Aspects of Organic Cropping Systems in the Dryland Pacific Northwest
Of the 4.8 million acres devoted to organic winter wheat (Triticum aestivum L.) production in the U.S., less than 1% of organic wheat acreage is located in Washington State, despite the highly productive soils and record ...
EFFECT OF HEAT AND DROUGHT STRESS IN QUINOA (Chenopodium quinoa Willd.)
Quinoa is an Andean grain crop from South America. It is recognized due to its high nutritional value and tolerance to marginal agronomic environments. High temperature and dry environments are the primary challenges to ...
