Cover crop effect on soil microbial biomass after fumigation in potato fields in the Columbia Basin

Creator:: Kim, Esther
Abstract:: In the Columbia Basin, pre-plant soil fumigation is commonly used in potato production for pest control, but fumigation can kill non-target organisms within the soil, result in unintended shifts in the microbial community, and disrupt long-term soil health. Cover crops have been shown to strongly influence the numbers and communities...

Investigating the Potential of Slow Release Nitrogen Fertilizer to Increase Agricultural Nitrogen Management Efficiency for Tall Fescue in the Southern Willamette Valley

Creator:: Derksen, Jacob Z.
Abstract:: Nitrogen (N) fertilizer application can promote nitrate leaching below the rooting zone and into groundwater drinking water sources in many agricultural settings. The proper management of N application can minimize non-point source nitrate pollution to groundwater. This study examines the potential for enhanced efficiency fertilizers, specifically urea treated with a...

Chemical Control of Suckers in Hazelnuts (Corylus avellana): Comparing Herbicide Efficacy, Spray Nozzle, and Carrier Volume

Creator:: Larocca de Souza, Larissa
Abstract:: Hazelnuts (Corylus avellana) produce a prolific growth in the base of the trunk and roots, known as suckers, which are often removed in order to promote the development of a single trunk tree. Sucker removal facilitates cultural practices and mechanized operations, such as weed management and harvest. Sucker presence can...

Soil Water Tension Irrigation Criteria Affects Both Stevia Rebaudiana Leaf Yield and Leaf Steviol Glycoside Composition

Creator:: Parris, Cheryl A.
Abstract:: Stevia (Stevia rebaudiana) is a perennial herbaceous plant native to Paraguay and used traditionally by the native Guarani peoples for centuries to sweeten medicinal teas. Stevia has only been commercially cultivated over the past 50 years and cultural practice information suitable for implementation by growers is limited. Currently stevia’s commercial...

Physiological effects of non-nutritive sugars on the survivorship and fecundity of Drosophila suzukii (Diptera: Drosophilidae)

Creator:: Tang, Siew Bee
Abstract:: Spotted wing drosophila (SWD), Drosophila suzukii, is an economically damaging pest on small fruits. The estimated economic impact is hundreds of millions of dollars annually in the U.S. alone, and increasing every year. Current control of SWD relies heavily on chemical insecticides which have many negative impacts on environmental and...

Thresholds of uncertainty : radiation and responsibility in the fallout controversy

Creator:: Jolly, J. Christopher
Abstract:: The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

Cross-cultural sweetness preferences for a sports drink

Creator:: Chung, Seo-Jin
Abstract:: Asian countries have become one of the largest export markets for US food developers during the past decade. Understanding consumer expectations and needs in a cross-cultural framework has gained importance for new products to succeed in the international markets. A sports-drink, which is a functional drink for athletes, has been...

Fluorimetric analysis of intracellular calcium in high and low mobility fowl sperm

Creator:: Olson, Jill Wardell
Abstract:: Sperm mobility is defined as the net movement of a sperm population against resistance. Previous research demonstrated that the cell-permeant Ca2+ indicator rhod-2 AM gave a fluorescent signal predominantly in the head region of fowl sperm that differed between sperm mobility phenotypes. This thesis served to explore the role of...

A modeling and experimental approach to understanding the bottlenecks in xylulose utilization in S. cerevisiae

Creator:: Hohenschuh, William
Abstract:: The production of fuel ethanol from lignocellulosic biomass has the potential to replace a significant portion of non-renewable transport fuels. Woody feedstocks are composed of cellulose, hemicellulose, and lignin. Glucose, the monomer of cellulose, is readily utilized by wild-type S. cerevisiae, but xylose, which comprises 60% of the sugar in...

Impact of malolactic fermentation on red wine color and color stability

Creator:: Burns, Tresider R.
Abstract:: Malolactic fermentation (MLF) is an important step in the production of wines and is commonly performed in red or cool climate wines to reduce acidity. In this study the impact of MLF on red wine color and the ability of Oenococcus oeni to degrade compounds important to the development of...
