Exploring Vitamin B9 Diversity for the Nutritional Improvement of Potato

Creator:: Robinson, Bruce R.
Abstract:: The cultivated potato, Solanum tuberosum L., has been one of the world’s most important food crops for more than 190 years and may become even more important to global food security in the coming 20 - 30 years. One of the world's largest growing health concerns is not just the...

Response of soil microbial communities and nitrogen cycling processes to changes in vegetation inputs

Creator:: Brewer, Elizabeth Ann
Abstract:: Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...

Predicting the spatial variability in soil properties using DSM across Malheur National Forest

Creator:: Seeno, Elizabeth A.
Abstract:: Soil properties may hold the key to improved predictions of soils during digital soil mapping (DSM), which has developed with a focus on environmental factors external to soil. The spatial variability in soil properties was modeled across Malheur National Forest in eastern Oregon as an approach to improve DSM. The...

Exploring Soil-Landscape Relationships on the Pacific Slope of Monteverde, Costa Rica

Creator:: Hesson, Kevin M.
Abstract:: Landscape positions have been used to determine soil properties. My soil study in Monteverde on the Pacific slope of Costa Rica was designed to examine soil-landscape relationships for sites with various land use histories and management. Soil pits were dug at Nacimiento y Vida, Crandell, Curi-cancha, La Calandria, and Finca...

Improving Best Management Practices for Potato Production in the Columbia Basin : An Evaluation of Essential Oils for Control of Verticillium Wilt and the Fate of Chloride in the System

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

Integrating restoration and ecologically based weed management practices for invasive knotweed control

Creator:: Rudenko, Melody
Abstract:: Japanese knotweed is an invasive perennial shrub that dominates riparian ecosystems. Effective management techniques are currently limited to repeated annual herbicide applications and there is little science-based information about which control tactics result in the greatest management success. Restoration of invaded sites to a functioning riparian plant community is needed...

Microbial community structure as influenced by season and stand age in a Douglas-fir (Pseudotsuga menziesii) ecosystem

Creator:: Kucera, Jennifer Moore
Abstract:: Forest harvest can have significant impacts on forest ecosystems that may influence the capacity of soils to sequester carbon (C). The microbial community controls decomposition, which is a critical process in partitioning litter- and root-C between CO₂ and storage in semi-permanent soil-C pools. The objectives of this study were to...

Evaluation of Monitoring Traps for Drosophila suzukii (Diptera: Drosophilidae) in North America

Creator:: Lee, Jana C., Burrack, Hannah J., Barrantes, Luz D., Beers, Elizabeth H., Dreves, Amy J., Hamby, Kelly A., Haviland, David R., Isaacs, Rufus, Richardson, Tamara A., Shearer, Peter W., Stanley, Cory A., Walsh, Doug B., Walton, Vaughn M., Zalom, Frank G., and Bruck, Denny J.
Abstract:: Drosophila suzukii Matsumura (Diptera: Drosophilidae), a recent invasive pest of small and stone fruits, has been detected in more than half of the U.S. states, and in Canada, Mexico, and Europe. Upon discovery, several different trap designs were recommended for monitoring. This study compared the trap designs across seven states/provinces...

Producing fiber flax using modern machinery and field retting

Creator:: Kennedy, Ralph C.
Abstract:: Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in Oregon around 1957 before newly developed technology and fiber cultivars were available. The purpose of this research was to explore the use of modern methods and new cultivars. Field studies were conducted to evaluate cultivars and optimum cultural...

Water management effects on birdsfoot trefoil seed production

Creator:: García-Díaz, Carlos Alberto
Abstract:: There is no information available on water management of birdsfoot trefoil grown for seed. Information is also not available describing how to minimize seed losses due to shattering in order to obtain consistently high birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify crop water use,...
