INVESTIGATIONS INTO PRACTICAL APPLICATIONS FOR THE CRITICAL WATER ACTIVITY FROM DYNAMIC DEWPOINT ISOTHERMS
(2015)
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
(2016)
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 ...
Genetics of drought tolerance in common bean (Phaseolus vulgaris L.)
(2015)
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) ...
Rotational Cropping Systems for Nitrogen Management and Weed Control in Dryland Organic Wheat Production
(2012)
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 ...
Pyroxsulam Persistence, Adsorption, and Movement in Palouse Soils
(2017)
Instances of herbicide persistence contributing to injury of sensitive rotational crops in the Palouse are common. As a consequence, the Palouse has a reputation for unexpectedly long herbicide persistence among industry, ...
Local Biosolids Compost: Agricultural Use, Fate of Antibiotics, and Community Engagement
(2014)
We investigated the agricultural use of locally produced biosolids compost, the fate of the antibiotic ciprofloxacin during the composting process, community perceptions about biosolids, and sociological factors of community ...
Characterization of glyphosate-resistant mechanism(s) in spring wheat (Triticum aestivum L.) induced through mutagenesis
(2015)
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) ...
Identifying root-lesion nematode (Pratylenchus spp.) resistance and functional mechanisms in wheat
(2013)
Root-lesion nematodes (RLN) Pratylenchus thornei Sher and Allen, 1953 and P. neglectus (Rensch, 1924) Filipjev Schuurmans and Stekhoven are soil-borne pathogens of wheat that invade and feed on root host cells. In the ...
EFFECTS OF GENOTYPE, FERTILIZER, AND MYCORRHIZAL FUNGI ON PHOSPHORUS USE EFFICIENCY OF ORGANIC AND CONVENTIONAL SPRING WHEAT
(2012)
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 ...
EMPIRICAL ANALYSIS OF THE FRESH TREE FRUIT MARKET
(2011)
This dissertation is composed of three studies. First, fresh tree fruit demand at the farm gate is modeled to estimate price elasticities and export elasticities. Second, fresh fruit demand is estimated for the consumer ...
