Determining The Difficulties Of Ornamental Horticulture Programs, Elizabeth Basham

Agricultural Education and Communication

The purpose of this senior project was to develop a survey to determine the difficulties that high school ornamental horticulture instructors were facing with their programs. Many schools throughout California have faced difficulties with their programs and have had to limit the offerings of the courses that would have been available to their students. Based upon the results from the survey it was determined that many of the instructors felt that their programs had been declining in success due to budget limitations, student involvement, standardized testing requirements and community support. The results of the survey can be utilized to aid …

Nest And Brood Site Selection And Survival Of Greater Prairie-Chickens In The Eastern Sandhills Of Nebraska, Lars Anderson

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Greater prairie-chickens (Tympanuchus cupido pinnata) are a grassland bird species of conservation concern. Although greater prairie-chickens have declined over much of their range, the Nebraska Sandhills has the largest population in North America. However, the responses of nest and brood site selection and survival to vegetation characteristics are unknown. I studied prairie-chickens on private rangelands in Rock and Brown Counties from 2009-2011. I fitted 139 females with radio collars to locate nest and brood sites and to determine nest and brood survival rates. Females were trapped on leks during the breeding season and I monitored them throughout the …

Insecticidal Control Of Bemisia Tabaci (Hemiptera: Aleyrodidae) Transmitting Carlavirus On Soybeans And Detection Of The Virus In Alternate Hosts, Difabachew K. Belay, Randy M. Huckaba, Axel M. Ramirez, Jose C. V. Rodrigues, John E. Foster

Department of Entomology: Faculty Publications

A Carlavirus transmitted by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is an important disease of soybean nurseries in Puerto Rico causing substantial germplasm losses. Insecticide bioassay experiments were conducted at Dow AgroSciences (DAS) Research Station, Santa Isabel, Puerto Rico, either by spraying insecticides on B. tabaci infested soybean leaves or introducing B. tabaci adults onto insecticide-sprayed soybean leaves. Moreover, host plants were surveyed to detect the virus in overwintering hosts that serve as a source of inoculums. The direct spray experiment showed that Nuprid 2F (Imidacloprid), Capture 2 EC (Bifenthrin), Thionex (Endosulfan), Lannate LV (Methomyl), and Dimethoate gave good level ( …

Coping Mechanisms And Level Of Occupational Stress Among Agriculture Teachers And Other Teaching Populations, Kasee L. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teacher stress has been a concern in educational research for several decades. This research sought to identify the specific coping methods which Utah agriculture and non-agriculture teachers utilize to manage potentially stressful events, and to determine if differences exist in the coping mechanisms used between agriculture teacher and non-agriculture teacher groups.

Results showed that agriculture teachers showed a greater level of occupational stress than non-agriculture teachers. It was also concluded that occupational stress for the two teaching groups came from different sources. In regard to the agriculture teacher group, certain demographic characteristics that led to a higher frequency of use …

A Baseline Study Of Biofuel Feedstock Growth On Non-Traditional Agronomic Land In Utah, Dallas A. Hanks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nearly all highway, airport, and military areas in Utah cost money to maintain and are often safe harbor for noxious weeds and pests. This project hypothesized that money could be saved and biofuel feedstocks could be grown in these areas, improving sustainability. Agronomic conditions and growth methods were tested to determine if biofuel feedstock production could occur on these marginal, non-traditional plots of land. Models developed illustrate that maintenance costs for these areas can be nullified if oilseed crops grown yield 600 pounds/acre and are used for biodiesel production. This feedstock yield would result in approximately 25 gallons of biodiesel …

Cultivating An Opportunity: Access And Inclusion In Seattle's Community Gardens, Alice K. Opalka

Scripps Senior Theses

This thesis explores the social dynamics of community gardens and their participation within them in the contemporary food justice movement in Seattle, Washington. Community gardens are seen as solutions to myriad urban and environmental problems, such as food deserts, community empowerment, urban greening, environmental education and sustainability of the food system. Three case studies of Seattle organizations, the P-Patch Program, Lettuce Link and Alleycat Acres, provide a basis for analysis of the purported benefit of community empowerment as a function of organizational structure, history and policies. City government support, flexibility, and a critical outlook towards the processes of inclusion and …

Serving As Suppliers To Institutional Foodservices: Supply Chain Considerations Of Small And Medium Scale Specialty Crop Producers, Laura Westray

All Theses

Institutional foodservice, which includes schools, hospitals, and long-term care facilities, is an important food marketing channel. The centralized nature of the US food system effectively, and supply, logistic and other constraints, effectively precludes small and medium scale (SMS) specialty crop producers from serving as suppliers to these types of operations. Passage of The Food Safety Modernization Act (FSMA) and increasing public attention to food safety issues, further complicates this matter. While the FSMA Tester-Hagen Amendment provides regulatory exemptions for SME producers, it is likely that in the future food purchases on or behalf of institutions will require more stringent food …

Investing In Genetics, Bridger Feuz, Dillon M. Feuz

All Current Publications

Agriculture Extension professionals as well as other agriculture industry professionals often extol the virtues of being the” low cost producer.” In most cases being the low cost producer does lead to an increase in profitability. However, two different data sets have suggested a couple of areas that high profit producers actually spend more money on then low profit producers.

Performance Characteristics Of Rayon From Bamboo In Bed Sheets Through Laundering, Jennifer Kohler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years, consumers have been encouraged to purchase bamboo fabric for various applications, including bed sheets. A variety of claims and marketing campaigns have stated that the benefits of rayon from bamboo result in this fiber being a suitable option for bed sheets and other clothing and household products. The purpose of this study was to test the performance characteristics of rayon from bamboo to determine if it is an appropriate textile for the bed sheet application. To identify the performance characteristics of this fiber, three tests were conducted (a) dimensional stability; (b) fabric hand; (c) the weight, thickness, …

Anabaena In Eutrophic Conditions, Benjamin Rayikanti

Creative Activity and Research Day - CARD

Microorganisms have been used to aid in the cultivation of plants for centuries. One of these microorganisms is Anabaena, a genus of cyanobacteria that has been shown to enhance nitrogen fixation and grain yield in wetland rice fields. This project will investigate if increasing bacterial growth rate under eutrophic conditions (i.e., high phosphate) could potentially increase nitrogen fixation by Anabaena. Phosphorous concentration will be varied to determine the effect on growth rate as measured by changes in cell number and chlorophyll concentration.Anabaena can provide an organic, low cost and efficient way to provide a nitrogen source for …

Diversification Of Organic Cropping Systems With Cover Crop Mixtures: Influence On Weed Communities, Soil Microbial Community Structure, Soil Moisture And Nitrogen, And Crop Yield, Samuel E. Wortman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Organic grain cropping systems typically depend on intensive mechanical cultivation for weed control and manure or compost applications to meet plant nutrient demands. However, cover crops may contribute to weed suppression and soil fertility, potentially increasing crop yield and sustainability of the system. The utility of individual cover crop species have been well documented, but the agronomic benefits of diverse cover crop mixtures have received less attention. Cover crop mixtures are an appealing option for farmers, as increasing species diversity has been shown to increase resource-use efficiency, stability, resiliency, and productivity of plant communities. Despite the growing interest in cover …
