Observing Orobanche Uniflora Parasitism Of Four Sedum Species In Relation To Soil Composition, Devin J. Forest-Hines, Sophie Wille, Noah Flick, Maxxie Barr
Student Research Symposium
Sedums are commonly selected for green roof applications due to their horizontal growth, heat and drought tolerance, water-storage capacity, and heat absorption. A potential threat to sedum health is the presence of parasitic Orobanche. Orobanche are a genus of parasitic plants that extract nutrients, water and carbohydrates from its host via root attachments. This study seeks to investigate Orobanche parasitism on the four most abundant sedum species on a Portland State University green roof in relation to soil composition. Four sedum species were propagated in clear plastic compact-disc (CD) cases containing either mineral substrate, Miracle Gro, or a seedling mix, …

Senior Theses and Projects
With the progressive nature of climate change conditions globally over the past century, there has been increasing focus on conservation of all species, but particularly those already endangered. Over 12,000 species of ferns live on Earth, and they do not produce seeds, so an investigation into their spores and how they reach maturity will allow us to preserve more genetic material in the future for these species. As a result, we investigated ex situ conservation and survivability of in vitro cultured gametophytes of within the genus Dryopteridaceae through herbarium sample germination rates across samples representing a wide age range ( …

In the Central American country of Guatemala, firewood is an important fuel source. Eighty-eight percent of households in rural areas use wood stoves and open fires to cook and heat their homes. This tradition has fundamental roots in the culture and customs of Guatemala. Unfortunately, these methods contribute to air pollution. Consequently, it also results in smoke inhalation, which causes health problems. Additionally, the massive agriculture of other crops decreases the amount of firewood available to these households, affecting the sustainability of the resource. Some communities resist changing their use of firewood due to the profound nature that firewood holds …

Processes For Improved Variable Rate Irrigation And Nitrogen Within Potato-Wheat-Wheat Cropping Systems, Elisa A. Flint
All Graduate Theses and Dissertations, Fall 2023 to Present
Proper irrigation and nutrient management are vital for optimal crop production within agricultural fields. Improving irrigation and nutrient application through precision agriculture is necessary to conserve the limited resources available, while improving yield and quality of crops produced through such a system. Variable rate irrigation (VRI) and variable rate nitrogen are systems used to apply water and nitrogen more precisely to agricultural fields to reduce runoff, deep percolation, leaching, and other negative impacts of over application, while providing the optimal rates to produce maximum yields. However, the processes to utilize these systems have proven to be more difficult than expected, …

Near-Surface Soil Property Change Over Time In Two Native Tallgrass Prairies In The Arkansas River Valley, Katie Jansson
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
One climate-change mitigation pathway is soil carbon (C) sequestration, which removes carbon dioxide from the atmosphere and stores C in various forms in the soil. Native prairie soils have long been known for their soil C sequestration abilities, but the full extent of their sequestration capacity is not completely understood. This study evaluated the effect of soil depth and soil map unit/prairie combination on changes in various soil properties over time from 2018 to 2022 in the top 20 cm of two native tallgrass prairie soils in the Arkansas River Valley in west-central Arkansas. Soil samples were collected from the …

Comparison Of Private And Public Lab Fertilizer Recommendation Impacts On Field Crop Production And Soil Test Results, Megan Baker
All Graduate Theses and Dissertations, Fall 2023 to Present
There are many sources that farmers utilize to determine fertilizer needs for crops such as private and public labs, crop advisors, and fertilizer dealers. In many cases, these sources provide recommendations for a specific crop that can vary greatly, which can lead to large differences in cost. An experiment was established in 2021 with 12 sites across the state of Utah in alfalfa, small grains, and corn to test and compare fertilizer recommendations from five labs. The recommendations tested were from two public labs (Utah State University and the University of Idaho) and three commercial labs located in the Western …

How Is International Orchid Trade Regulated, And How Effective Are Those Regulations?, Madeline Roubik
Mary Ann Bolton Undergraduate Research Award
When investigating the trafficking of wild species, animals are often considered before plants (Phelps et al. 2015). This is especially detrimental to members of the orchidaceae family, which are victims of an extensive illegal trade. It spans the entire globe but is especially concentrated in Southeastern Asia (Phelps et al. 2015). When regarding legislation, however, orchidaceae species are some of the most protected in the world. International legislation such as CITES restricts the movement of endangered orchidaceae across borders (Hinsley 2018). The 1992 Convention on Biodiversity (Lawson et al. 2019) also has policies regarding international orchid trade. National laws regulate …

Sustainable Fertilizer Management Practices For Container Nursery Production, Saroj Burlakoti
All Graduate Theses and Dissertations, Fall 2023 to Present
Growing nursery plants in containers requires a timely supply of mineral nutrients for optimum growth. However, there is a misconception among growers that the application of higher doses of fertilizers hastens plant growth; instead, it can lead to runoff and leaching loss of nutrients. Reducing fertilizer application while sustaining healthy plants can not only negate environmental consequences but also save fertilizer costs. For example, two ground covers, Lysimachia nummularia (creeping jenny, moneywort) and Vinca minor 'Bowles' (periwinkle), can be grown for three months by applying 6 mg/L of phosphorus (P) as reduction of P to single application of 6 mg/L …

Nutrient Management Of Cannabis In Controlled Environments, Julie A. Hershkowitz
All Graduate Theses and Dissertations, Fall 2023 to Present
Cannabis has been cultivated for millennia as a multipurpose crop for food, fiber, and medicine. Secondary metabolites called cannabinoids, including cannabidiol (CBD) and the psychoactive Δ-9 tetrahydrocannabinol (Δ-9 THC), are responsible for the medicinal properties of cannabis. The intoxicating nature of THC resulted in legislation prohibiting the possession and production of cannabis within the United States during the 20th century. As a result, research programs on cannabis production were halted at most institutions. In recent years, cannabis production has become widespread within the US as a result of increasing legalization. However, modern cannabis production nutrient management programs often include …
