Hybrid Bermudagrass And Kentucky Bluegrass Response Under Deficit Irrigation In A Semi-Arid, Cool Season Climate, Hanna R. Burgin Nov 2021

Hybrid Bermudagrass And Kentucky Bluegrass Response Under Deficit Irrigation In A Semi-Arid, Cool Season Climate, Hanna R. Burgin

Theses and Dissertations

As average global temperatures rise, cool-season C3 turfgrasses, such as the most commonly grown Kentucky bluegrass (Poa pratensis L.; KBG), struggle to tolerate extreme summer heat and increase their water consumption. Hybrid Bermudagrass (Cynodon dactylon [L.] Pers. × Cynodon transvaalensis Burtt Davy; HBG) is a warm-season C4 grass that may be increasingly suited for northern ecosystems traditionally classified as transition or cool-season climate zones. Glasshouse and field studies were conducted to compare HBG and KBG water use. The objective of the glasshouse study was to evaluate plant health and growth for two HBG cultivars (‘DT-1’ and ‘NorthBridge’) compared to a …


Lymphocyte Proteomics For Monitoring Long Term Immune System Dynamics, Michaela Mccown Mar 2021

Lymphocyte Proteomics For Monitoring Long Term Immune System Dynamics, Michaela Mccown

Undergraduate Honors Theses

Time dependent change in lymphocytes provides a necessary background for monitoring the development of Chronic Lymphocytic Leukemia from asymptomatic to malignant. Several bulk proteomics studies characterize differences between tumor cells and healthy B cells, yet the transition to symptomatic disease is not well understood. This could be shown by a longitudinal study beginning with asymptomatic patients if the rare tumor cells in early stages can be isolated from small volume blood draws and effectively characterized with few cells, such as was done here using healthy B cells to provide a baseline for such studies to discriminate routine fluctuation from pathogenic …


Spatiotemporal Analysis Of Variability In Soil Volumetric Water Content And Spatial Statistical Methods For Management Zone Delineation For Variable Rate Irrigation, Isak Lars Larsen Mar 2021

Spatiotemporal Analysis Of Variability In Soil Volumetric Water Content And Spatial Statistical Methods For Management Zone Delineation For Variable Rate Irrigation, Isak Lars Larsen

Theses and Dissertations

Irrigated agriculture is the largest user of freshwater in a world experiencing increased water scarcity and water demands. Variable rate irrigation (VRI) aims to use water efficiently in crop production, resulting in good yields and water conservation. With VRI, the grower is able to employ custom irrigation rates for different parts of a field. Adoption of VRI has been limited due to the complexity of matching irrigation to spatiotemporal crop water needs and the cost/benefit economics of VRI equipment. The goal of this study was to quantify spatiotemporal variability of VWC in a field that has uniform soil type and …
