A Management Study Of The Cache Elk Herd, Norman V. Hancock May 1955

A Management Study Of The Cache Elk Herd, Norman V. Hancock

All Graduate Theses and Dissertations

American elk, by virtue of their distributio.n, were the most cosmopolitan members of the cervid family at the time of white settlement of North America. At this early date elk were present in every major region of what is now continental United States, as well as in northern Mexico. They likewise were abundant in upper and lower Canada, though records do not corroborate their presence too far north on the Atlantic coast. Although generally existent throughout the western states, elk were sparsely distributed in Nevada, southern Utah, and most of Arizona and New Mexico. Paucity of elk was also ...


Chemical Thinning Studies On Peaches In Utah, Ramzi Mustafa Khalidy May 1955

Chemical Thinning Studies On Peaches In Utah, Ramzi Mustafa Khalidy

All Graduate Theses and Dissertations

Investigations on chemical thinning of peaches by use of blossom and post blossom sprays have been in progress since the last decade mainly in the United States, Canada, and some European countries. Horticulturists are attempting to find new means to minimize the expense of hand thinning. The high cost of the hand thinning operation has caused many growers to underestimate the importance of this practice, and as a result their orchards have fallen into the biennial bearing habit. In addition, the fruit from un-thinned orchards was not acceptable on the market since it was small in size, lacked color, and ...

The Biology And Seasonal Distribution Of Eucalliphora Lilaea (Walker) In Cache County, Utah, Robert P. Olson

All Graduate Theses and Dissertations

The association of: flies with man has been recorded through many centuries. In nearly all of these records the association is one of discord rather than harmony. In the Book of Exodus, 8:24, in the King James version of the Old Testament, we can read, "...and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses; and in all the land of Egypt the land was corrupted by reason of the swarms of flies." Centuries later the "grievous swarms of flies" 'were associated with a particular disease by Mercurialis. In 1577 he expressed ...


Factors That Contribute To Success Of Selected Farm Ownership Borrowers In Utah, Grey M. Jensen May 1954

Factors That Contribute To Success Of Selected Farm Ownership Borrowers In Utah, Grey M. Jensen

All Graduate Theses and Dissertations

Farming is a complex business. Financial success in farming is influenced by the organization and operation of the farm unit. The principal problem confronting farmers is knowing how to manage the resources to attain maximum income over a period of time. Combinations of resources involve problems relative to crops, livestock, machinery, labor, capital, credit, and many others. An attempt has been made in this study to measure the results of different combinations and operation of resources and to determine their association with financial success of the farm.


The Economics Of Rural Residential Zoning In Utah County, Max K. Buchmiller May 1954

The Economics Of Rural Residential Zoning In Utah County, Max K. Buchmiller

All Graduate Theses and Dissertations

Change in the use to which land is put may affect the economic and social return from it. Land-use changes tend to be rather permanent in nature. They should be guided so that social welfare will be served best. Rural Zoning has developed from this need to direct change in land use in rural areas.

It first came into use about twenty-four years ago but was developed from much older, urban-zoning experience. By 1949, rural-zoning ordinances had been adopted by 173 counties in 23 states. Thirty-eight states had passed enabling acts permitting the adoption of rural-zoning ordinances by specified political ...

Mileage Per First Service As Affected By Shape Of Area And Number Of Cows Serviced By A Technician Of A Utah Artificial Breeding Association, Geren V. Howell

All Graduate Theses and Dissertations

Artificial insemination of dairy cattle is one of the recent enterprises of dairymen in this area. It is an enterprise which has expanded rapidly and will likely continue to expand during the next few years. In this area the technician or inseminator collects from $6.00 to $10.00 at the time of first service. This entitles the dairyman to two repeat inseminations for that cow, if necessary, to get the cow pregnant. Of this amount the technician receives $2.75. A bonus payment is made so that technicians inseminating fewer than 500 cows receive a total payment of $3 ...


The Status And Management Of Pheasant Posted Hunting Areas In Utah, William G. Parsons May 1953

The Status And Management Of Pheasant Posted Hunting Areas In Utah, William G. Parsons

All Graduate Theses and Dissertations

Since 1900 the ringneck pheasant Phasianus colchicus torquatus Gmelin has assumed major importance in the United states as an upland game bird. This is particularly evident in utah where, in 1951, 76,000 hunters bagged an estimated one quarter million pheasants (8). It is axiomatic that pheasant habitat in Utah is largely confined to land under irrigation. In Utah, this comprises onlY 2.2 percent of the total land area. These areas, essentially bottomlands along stream courses, are intensively farmed and generally assessed a high valuation per acre. Associated with intensive farming are population centers and resultant concentrations of hunters ...

Studies In The Life History And Ecology Of The American Pintail (Anas Acuta Tzitzihoa Vieliot) In Utah, Robert W. Fuller

All Graduate Theses and Dissertations

Wildlife management has been defined as lithe manipulation of wild populations of vertebrate animals in their relation to man and his interests" Wildlife management, then, could not exist in the absence ot either wildlife or humans. Converting this idea to the waterfowl situation, we can say that there are no waterfowl problems other than as they exist in the minds of men. (Wil1s, 1951) These words by the Chief of the IllinoIs Natural History Survey precede a plea for fundamental facts and a basic understanding of waterfowl upon which sound management can in turn be based. l"or only through ...


Some Of The Relationships Between Livestock Grazing And Duck Nesting In The Saltgrass Vegetation Type In Utah, Horatio W. Murdy May 1953

Some Of The Relationships Between Livestock Grazing And Duck Nesting In The Saltgrass Vegetation Type In Utah, Horatio W. Murdy

All Graduate Theses and Dissertations

Little is known of the relationships between livestock grazlng and duck nesting. This dearth of information occurs in spite of the fact that an understanding of these relationshipships is necessary in order to evaluate duck production on range land, and to formulate grazing policies for lands devoted to the production of ducks. Recognizing the need for information on this subject, the Utah Cooperative Wlldllfe Research Unit and the Wildlife Management Institute jointly sponsored a study, during 1948-1949, of livestock grazing-duck nesting relationships in the saltgrass vegetation type in northern Utah. The study was financed by the Institute and supervised by ...

In the year 1951 Utah ranked seventh in the nation in turkey production (5). The production of turkeys has risen from a humble beginning to one of the important agriculture enterprises in Utah.


The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum Jun 1952

The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum

Theses and Dissertations

To an entomologist, the Orthoptera1 is in a state of confusion with respect to the available literature. Work has been done, and is now being done on the orthopteran fauna, but manuals tor identification of most species are not available for all sections or the country. Exclusive of a few lim-ited groups, Utah is among the areas that has no complete keys for taxonomic workers. In biological ivenstigations identification is essential: The species being studied must be definitely known. The primary purpose of this study, therefore, is to list the Utah Orthoptera and provide the keys necessary to their critical ...


An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield May 1952

An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield

All Graduate Theses and Dissertations

Turkey raising has become big business. During the period 1942 to 1946, the average annual return in Utah amounted to about nine and one half million dollars (4). This amount would have been increased considerably if the death loss among poults had been lower. As an example, using the percentages of mortality given by Miner (9, P. 5), it is estimated that the death-loss of turkeys in 1944 resulted in a loss of gross income by the farmers of Utah of more than four million dollars provided that the price the farmer received had remained the same.


The Consumptive Use Of Water In Milford Valley, Utah, Terrel R. Tovey May 1952

The Consumptive Use Of Water In Milford Valley, Utah, Terrel R. Tovey

All Graduate Theses and Dissertations

Consumptive use, as used in this thesis, is defined as the sum of the volumes of water used by the vegetative growth of a given area in transpiration and building of plant tissue and that evaporated from adjacent soil, snow, or intercepted precipitation of the area in any specified time, divided by the given area. If the unit of time is small, the consumptive use is expressed in acre-inches per acre or depth in inches, whereas, if the unit of time is large, such as growing season or a 12-month peiod, the consumptive use is expressed as acre-feet per acre ...

A Curriculum Study Of The Biological Science Courses In The Secondary Schools And College Of Utah During 1947-48, Merrill H. Gunnell

All Graduate Theses and Dissertations

At the present time there is a feeling among biologists in Utah that there should be iimprovement in biological science courses and course sequence to better fill the needs of the non technical student. There are many students filling group requirements with an accumulation of courses which may not provide them with the more important fundamental concepts and principles in biology. Information concerning these courses in high schools and colleges in necessary to provide a basis for curriculum revision in the field. Such information should be useful in evaluating the present system and suggesting modifications. Because of the need for ...


Utilization Of Forage Plants And Diet Of Sheep On Utah Winter Range, Lisle R. Green May 1948

Utilization Of Forage Plants And Diet Of Sheep On Utah Winter Range, Lisle R. Green

All Graduate Theses and Dissertations

Although there is an abudance of material available concering forage consumption by livestock on pasture land and in the feed lot, there is relatively little known about the grazing habits and forage preferences of livestock under range conditions. There has been still less scientific effort expended toward solving the riddle of the grazing animal's diet under winter range conditions. Investigators have suggested means to determine the quantity of forage available on range areas, the carrying capacities of range lands, and methods of determining the degree to which forage has been utilized. The diet of the foraging animal is affected ...


A Taxonomic Study Of The Scolytidae (Coleoptera) Of The Logan Canyon Area Of Utah, Stephen L. Wood May 1947

A Taxonomic Study Of The Scolytidae (Coleoptera) Of The Logan Canyon Area Of Utah, Stephen L. Wood

All Graduate Theses and Dissertations

In spite of the great economic importance of north American Scolytidae, many taxonomic descriptions remain inadequate for the identification of species, and existing keys have been made obsolete by the recent description of new species. To bring these keys up to date and make them useful to students and practical foresters, detailed studies of the morphological structure of the various species are necessary. The purpose of the present investigation has been to clarify and revise existing keys and to describe briefly the species of Scolytidae occurring in the Logan Canyon area of Utah. The following keys and descriptions will be ...


The Cost Of Producing Eggs And The Egg Feed Ratio In Utah 1929-'46, Emer E. Broadbent May 1947

The Cost Of Producing Eggs And The Egg Feed Ratio In Utah 1929-'46, Emer E. Broadbent

All Graduate Theses and Dissertations

Commercial egg production in Utah has developed largely since 1920. Prior to that time most farms had some chickens but the eggs were either used at home or consumed on the local markets. What few commercial poultry farms there were also supplied local markets. It has been estimated that the total egg production in the stat was just about equal to the consumption within the state. Soon after1920 however, egg production on a commercial basis began and thereafter expanded rapidly for a time.

History Of The Cotton Mission And Cotton Culture In Utah, Ivan J. Barrett

Theses and Dissertations

The writer, being interested in the agricultural project of cotton growing in early Dixie, and finding scarcely anything written on the subject, has gone into the original sources, histories, journals, diaries, etc., and found a reservoir of enlightenment regarding cotton culture in Utah's Dixie. He has tried to assemble from the most important sources, an informative yet interesting study of cotton culture in Utah. The writer in no wise pretends to have exhausted the subject, nor to have reached all the sources. Many of those early cotton growers who did most to produce this staple, kept no record of ...


Wool Scouring Tests In Utah, Alma C. Esplin May 1941

Wool Scouring Tests In Utah, Alma C. Esplin

All Graduate Theses and Dissertations

Wool as it is shorn from the sheep, is known as grease wool. The first tep in the manufacturing of wool is scouring, or removal of all grease and foreign matter. Within any given grade, as determined by length of staple and fineness of fiber, the yield of clean wool is the primary factor in determining the value of the original grease wool. The price of scoured or clean wool is multiplied by the percentage yield of clean wool to determine the value of the grease wool. Wool is graded and sorted before being scoured by the manufacturer. Large quantities ...
