Maintenance of a balanced muskrat population is important to marsh management, therefore necessitating accurate density estimates. Feasibility of a vegetational utilization index as a reliable population indicator is being tested at Fish Springs NWR, Utah.

Irrigating For Rainbows, Jack Keller

Faculty Honor Lectures

Quite simply. irrigation is the act of applying water to land. It is usually done to improve plant growth and it lies somewhere between an art. a science. and plain hard work.

Economic Impacts Of Public Grazing Reductions In The Livestock Industry With Emphasis On Utah, Deevon Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper was to determine the immediate impact of reductions in public grazing on livestock production in the United States. This was accomplished by the use of linear programming techniques. Different grazing reduction simulations were utilized to determine the short and long run effects of across-the-board reductions in public grazing.

The United States was divided into 13 regions. The 11 western states were considered as individual regions. Special emphasis was placed on the effects of grazing reduction on Utah. The availability and utilization of feed and livestock products during a "normal year", 1978, were considered in this …

The 160-Acre Limitation And Economies Of Size: A Case Study In The Uintah Basin, Thomas C. Hatch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to analyze the economies of size in farming in the Roosevelt-Myton area of the Uintah Basin and to assess their impact on the financial viability of different size farms. This information will be useful in recommending changes to reclamation law.

Farmer interviews were used to obtain costs of production for 160, 320, 640, and 1280 acre farms. The field data were entered into the Oklahoma State Budget Generator to provide the necessary cost breakdown. This in formation was used to derive a curve approximating the long run average cost curve and to determine the …

Job Competencies, Employment Demands, And Perceived Training Needs In Production Agriculture In Utah, James O. Summers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was limited to 165 farmers involved in various segments of production agriculture in the state of Utah. County agents and vocational agriculture teachers in each county nominated these farmers as candidates according to their respective farming operations.

The following six defined areas of production agriculture were used as selection criteria to insure equal input in the study: Beef, Dairy, Swine, Sheep, Poultry, and Crops. All farmers were surveyed by means of persona l interviews conducted by either county agents or vocational agriculture instructors in their respective counties. The surveying instrument used was developed through a thorough review of …

Propagation Of Quaking Aspen (Populus Tremuloides Michx.) From Root Cuttings, Karen Elizabeth Burr

Aspen Bibliography

Lateral root cuttings were collected at five quaking aspen (Populus tremuloides Michx.) clones in Larimer County, Colorado on October 2, 1977 and May 30, 1978. The October 1977 root cuttings were stored eight months in air-tight plastic bags at 0 to 4°C. On June 1, 1978 the stored (October 1977) and the fresh (May 1978) root cuttings were planted in a greenhouse propagation bench. All sprouts that developed were allowed to grow on half of the 10-cm long root cuttings randomly selected as controls. On the remaining half of the root cuttings, designated pruned, all but the tallest sprout were …
