Performance And Contributions Of The Green Industry To Utah's Economy, Lara Gale

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Landscaping and nursery enterprises, commonly known as green industry enterprises, can be found everywhere in Utah, and are necessary to create both aesthetic appeal and human well-being in the built environment. In order to understand the impact that events such as economic shocks or policy changes may have on the green industry, the baseline performance and contribution of the industry must be specified for comparison following these shocks. This study provides a summary and evaluation of the current performance of the green industry in Utah, and estimates the industry’s contributions to Utah’s economy in terms of transactions between industries, employee …

Nursery Production Of Selected Actinorhizal Species, Taun D. Beddes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An important aspect of sustainable landscaping includes utilization of plants requiring few to no inputs once installed. Limited research exists for many of these species. For this research, we chose four with potential for use: Mexican cliffrose (Purshia mexicana), silver buffaloberry (Shepherdia argentea), roundleaf buffaloberry (Shepherdia rotundifolia), and seaside alder (Alnus maritima). All are actinorhizal, meaning they form a symbiotic relationship with soil-borne Frankia bacteria that fix atmospheric N₂ for plant use. Many actinorhizal species are also native to arid environments where soils have low organic matter (OM) content. We suspect …

Evaluation Of Competition Between Turfgrass And Trees In The Landscape, Christopher A. Hendrickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population growth in regions of the Intermountain West has resulted in rapid growth of residential neighborhoods. In Utah, the landscapes associated with these expanding neighborhoods consume vast quantities of treated water. This is a concern in all states of the Intermountain West, as water becomes increasingly scarce. Traditionally used turfgrasses, trees and other plants in Intermountain West landscapes require significant amounts of supplemental water considering the intense sunlight, dry winds and sparse rainfall typical of the region. Characterizing the interactions between turfgrass and tree species in these landscapes can aid in the identification of candidate species that consume less nutritional …

Competencies Needed For Careers In Ornamental Horticulture In Utah, Dennis George Bahen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the study was to present descriptive data bout the industry, determine the importance of the competencies needed for job entry, and assess the manpower needs of the ornamental horticulture industry in Utah.

The identified population of 576 ornamental horticulture enterprises was categorized into seven areas of specialization: Arborists (4.5%), Maintenance of Landscapes (10.8%), Landscape Construction (18.6%), Golf Courses (13.5%), Greenhouse Production (5.4%), Florist-Plant Shops (30.9%) and Garden Center-Nurseries (16.3%).

The data were collected by a survey-questionnaire. One hundred and sixteen ornamental horticulture enterprises responded to the survey. This amounted to 38% of the industry sampled and 20% …

The Effect Of Protective Materials On The Overwintering Of Hardy Annuals, Candytuft And Stocks, Melvin S. Burningham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many hardy annual flowers will live through the winter if there is sufficient snow protection. Since snow cover is not consistent from year to year it has been suggested that hardy annuals planted in late summer and provided with some kind of protection before severe freezing begins will live through the winter successfully. Not only would this enable plants to bloom four to six weeks earlier, but would also enable gardeners to utilize flowers not commonly grown in northern Utah.

Some studies conducted at the Utah Experiment Station in Farmington have indicated that plants such as candytuft and snapdragons can …

The Study Of The Effect Of Various Methods Of Harvesting And Curing On The Color And Viability Of Lima Bean Seed, S. G. Date

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many seedsmen have observed that lima bean seed of a variety like Early Thorogreen, which has green cotyledons, often fades in color during harvesting. This fading of color is known as bleaching. A variety which has green cotyledon and hence green seed, should retain this green color during harvest. Bleached seeds are likely to emerge slowly when planted. Also the final field stand from a planting of bleached seed is likely to be poor.
