Control Of Dodder In Alfalfa Seed Crops, William Orvid Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dodder (Cuscuta spp.) is a parasitic weed which attacks alfalfa, clovers, lespedeza, and many other species of plants. This pest is especially troublesome when these crops are grown to produce seed.

Control of dodder should increase the financial income of a seed producer in several ways. First, control should make it possible for a producer to raise seed of high quality which will command a better price; second, it should enable the producer to increase yields; and last, it should eliminate much of the cost of harvesting and cleaning his product.

Where dodder is present in seed, the grower …

Growth And Nutrition Of Plants As Affected By Various Levels Of Exchangeable Sodium, Mohammad B. Choudhri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In saline soils, which are characterized by an appreciable quantity of neutral soluble salts, plant growth is adversely affected due to the increase in osmotic pressure and the consequent decrease in the physiological availability of water. In addition, growth may also be restricted through the accumulation of toxic quantities of various ions within the plant.

On the other hand, alkali soils, whether saline or non-saline, are characterized by a high content of exchangeable sodium in the cation-exchange complex. One reason of low productivity on these soils is the unfavorable physical conditions induced by the dispersing action of the sodium ions. …

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

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

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.

Factors Affecting Length Of Tenure Of Vocational Agriculture Teachers Who Are Recent Graduates Of Utah State Agricultural College, John M. Oglesby

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since its beginning well over a quarter of a century ago, the Vocational Agriculture program has become an integral part of the American school system. The legislative groundwork for Vocational Agriculture, as well as all other vocational programs, was set in 1917 with the passing of the Smith-Hughes Act. Further related legislation was passed in 1929 and 1934, but the program received its greatest federal boost with the passing of the George-Deen Act in 1936 and the George-Barden Act in 1946, both of which provided for the annual expenditure of federal funds in support of vocational education. The George-Barden Law, …

Student Management Practices In The Secondary School Shops Of Utah, U. Sterling Cheney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Background

It is wrong to think that industrial education had its beginning recently. Merely because industry has made revolutionary changes and advancements during recent years does not mean that industrial education has not been in existence for a long time. Industrial education in some forms is probably as old as the human race.

In the development of industrial education it is interesting to note that both anciently and during modern times the emphasis has been placed on the value of handwork. The cave man's life depended upon his skill and ability to make and use the various types of primitive …

The Place Of The General Shop In The Industrial Arts Curriculum In The Secondary Schools Of Utah, Max E. Mckinnon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary purpose of education is to develop happy and successful citizens. Industrial arts, being a phase of general education, should in every way possible contribute toward achieving this primary purpose.

A Study Of Elementary Physical Education At The Whittier School, Logan, Utah, Phyllis C. Jacobson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the First World War, there has been an increased recognition for the need of physical education in the elementary school. Although educators recognize and agree on the need, they are not in agreement as to how to best achieve this need. Some educators believe that physical education should be taught as a specialized subject. Through this means, instruction is provided by a specialist who is trained in physical education. Some educators believe that physical education should be integrated with every other phase of the school program and taught by the classroom teacher. There are other educators who believe that …

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

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

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.

Marketing Aspects Of Cattle Finishing Operations Major Cattle Finishing Areas Of Utah, 1951-52, Robert L. Fulton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

On January 1, 1952, 50,000 head of cattle were on feed for slaughter in the state of Utah (6). This was an increase over previous years. The average number of cattle on feed for slaughter January 1st during the 1948-52 period was 45,000 head. This number was 30 percent larger than the average number on feed during the 1943-47 period. As shown in figure 1, the number of cattle on feed has fluctuated from year to year. The years with the least number of cattle on feed were those in the early thirties during the depression and drought. Since 1936 …

Effectiveness Of Evaporation From Ground And Foliage In Reducing Soil Moisture Depletion, Val D. Wynn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field irrigation efficiency is the percentage of the water delivered to the field that becomes available to the crop as soil moisture. The so-called "evaporation losses" from wetted ground and foliage are rather difficult to measure, but are estimated by Christiansen (3) to be between 15 and 30 percent. No doubt part of this may be termed as a "loss," but the other part may be incorrectly termed as such. Many authorities claim that water must pass through the plant before being transpired into the atmosphere to be effectively used.

Application Of Paper Electrochromatography To Isolation Of Tobacco Mosaic Virus, Bertram E. Bordewick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of the problem

The complete study of a virus disease often reaches a stalemate because of failure to isolate the virus itself in a purified form. Methods in current use, such as ultracentrifugation, precipitation, fractionation, and spectroscopic analysis, have in some cases proved successful in virus purification work. Frequently these techniques have not proved satisfactory, particularly with phloem-type viruses which are not mechanically transmitted. This investigation was undertaken to determine the possibility of isolating these and other viruses by electrochromatography.

Sediment Movement In Bear River, Utah, Calvin Geary Clyde

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the northern part of Cache Valley, Utah, accelerated erosion in recent decades has cut deep gullies of impressive size into the flat, irrigated bench land along the Bear River. Millions of tons of fine sediment have been washed into the river and great amounts have been deposited in the river bed. The resulting flooding and high water-table have caused much damage to the land near the river.

Industrial Arts In Utah--Its Introduction And Development, Charles W. Hailes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For the past few years many questions have been asked about the growth and development of the industrial arts program in Utah. Many of these questions could not be answered by leading educators. Thus, it is hoped that with the information presented in this report enlightenment may be given to unanswered questions.

The roots of present-day concepts and practices of industrial arts in Utah extend back about fifty years to the first schools established by the Mormon pioneers. The first school, in its simple setting, faced such issues as: What kind of industrial arts training shall be provided? How much …

An Analysis Of School Drop-Outs At Tooele High School, Franklin Whitehouse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study of approximately 50 early school drop-outs is an effort to find out why so many boys and girls leave school before they complete their high school course. We need to know the basic reasons that prompt their decisions, not the superficial excuses that appear on many school records. The study was undertaken in the belief that when the causes are understood, they can be remedied through measures to provide adequate programs of student aid. If it is because of lack of interest in school, this, too, can be remedied through changes in school programs to make them mean …

The Effects Of Fertilizers On The Yield, Carotene Content And Tocopherol Content Of Ranger Alfalfa Hay In Utah, Charles Wm. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is generally regarded as one of the world's most valuable cultivated forage crops. Few crops, if any, are equal to it in capacity to produce heavy yields of highly nutritious, palatable feed. A combination of desirable attributes as a forage plant and adaptation to a wide diversity of soil and climatic conditions has led to the use of alfalfa in the world to an extent probably exceeding that of any other single legume or grass. Alfalfa constantly proves itself as a valuable feed for most types of livestock. This is especially true in the states where a large amount …

Evaluation Of Male Physical Education Programs In Selected Secondary Schools Of Utah As Determined By The Standards Of The Utah State Course Of Study, F. Dale Robbins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Physical education has made unusually rapid progress during the past 50 years. Emphasis has deviated from absolute academic objectives to those permitting a well rounded educational program including the physical aspect. Physical education has been influenced by educational, spiritual, political, and social conditions.

As a result of these influences, the necessity of developing the physical has assumed major proportions. There is now a greater demand for physical education than ever before in the history of our country. For the welfare of not only the individual, but also to the state and nation, it is essential that an extremely high degree …

Merchandising Of Turkeys In The Principal Cities Of Utah, 1951-52, Joseph A. Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The production of turkeys comprises an important part of the cash farm income in Utah. In 1951 the cash receipts from turkeys amounted to $13,986,000, or 7.4 percent of the cash income from all farm commodities (4). 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.

Whereas a portion of the crop can be marketed at home, approximately 90 percent of the turkeys must be shipped to eastern markets. The Utah Turkey Federation, together with the …

Salt Movement And Forage Crop Establishment In A Saline-Alkali Soil As Influenced By Ridges And Furrows, Sprinkler Irrigation, And Soil Amendments, D. C. Purnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An estimated two to four million acres of irrigable saline and alkali soils of the United States return very little income to land owners (17,19). Increased needs for forage crops, and the relatively high salt and alkali tolerance of some improved forage species, once established, suggests a way of increasing revenue from some of these lands without costly reclamation.

Distribution Of Fluorine In Utah County, Utah, Soils And Uptake Of Fluorine By Plants, E. Don Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluorine released from industrial operations is eventually deposited on the surface of the earth, intercepted by plants, or absorbed in open bodies of water. the term fluorine as used in this thesis will be considered to refer to fluorine in combined form.

Industrial expansion has caused atmosphere pollution from fluorine in many parts of the United States. Utah County, Utah, is one of the affected area, and is the principal area of concern in this thesis.

Effects Of Season, Spacing And Intensity Of Seeding On Emergence And Survival Of Four Wheatgrass Species In Central Utah, Edwin B. Abbott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rehabilitation of deteriorated and abused range lands is being accomplished with greater success each year by the aid of better methods of seeding which include seedbed preparation, intensities of seeding, implements for planting and improved methods of eliminating competition. Much more information is needed, however, in order to recommend suitable methods and species for seeding various vegetation types and sones with reasonable reliability. Throughout the arid and semi-arid range lands, moisture is the principal factor limiting satisfactory seedling establishment. Special attention should therefore be given to more efficient utilization of the moisture supply. Closely related species or species with similar …

The Influence Of Temperature Gradients On Soil Moisture Flow, Luigi Cavassa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The isothermal movement of liquid water in saturated soil has been intensively studied, and a sound theoretical basis has been developed. Considerably less is known about the flow of water in unsaturated soils, but a general theory based on Darcy's law of flow is beginning to develop. A good theoretical basis exists for the vapor diffusion under isothermal conditions. Inconsistent data and theories are found in the literature concerning the movement of water in both the vapor and liquid phases, under the influence of thermal fields.

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, Spring 1920 to Summer 2023

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 sound …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

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).

The Total Surface Of Some Soils As Related To Permeability And Water Retention Characteristics, Warren W. Rasmussen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally recognized that many of the chemical and physical properties of soils are dependent upon the surface activity of the finer soil fractions. The importance of the magnitude of the surface areas to such properties as base exchange, water-holding capacity, absorption of gases, and the plasticity of soils has been demonstrated. Attempts have been made to determine or estimate the surface of soils and soil fractions by various methods and to relate the values obtained to the physical and chemical characteristics exhibited by these materials. Most determinations have been based on calculations of surface area from mechanical analysis …

Inheritance Of Ten Characters In Barley Crosses, Hazim Ahmed Al-Jibouri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Inheritance of many characters in barley has been studied, and two or more genes have been located in each of the seven pairs of chromosomes. Studies of the mode of inheritance of these characters will aid plant breeders materially in working with plants of diverse genetic make-up. Hybridization followed by selection and testing can improve present varieties by replacing them with new ones having more desirable characters.

Barley (Hordeum sp.) is one of the few species of plants widely distributed which is well adapted to genetical analysis. This plant has a lower number of chromosomes, complete self fertility, and a …

The Status Of The Elementary School Principalship In Utah, Sherman Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The aim of this study is to record the status of the elementary school principalship in the State of Utah during the 1951-1952 school year.

The problem arose from a situation in which the writer, as President of the Utah Elementary School Principal's Association, was continually asked questions pertaining to the status of this group, and because there was a scarcity of current information available upon which to base reliable answers to these requests.

This situation led to the formulation of the study herein presented--a survey of conditions as they existed in Utah during the 1951-1952 school year. It should …

The Influence Of Time And Rate Of Application Of Urea Spray On The Yield And Protein Content Of Winter Wheat, Vern L. Marble

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Winter wheat, with an annual average acreage of about 300,000 acres, forms an integral part of the farm economy of Utah.

For many years intermountain agronomists and farmers alike have known dry-land wheat production to be limited by low summer rainfall. In the past 15 years, however, it has become apparent through intelligent research that in many cases lack of nitrogen has been the limiting factor. When this occurs, winter wheat production can be increased by correcting this nitrogen deficiency

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, Spring 1920 to Summer 2023

Little is known of the relationships between livestock grazing and duck nesting. This dearth of information occurs in spite of the fact that an understanding of these relationships 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 Wildlife 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 …
