A Study Of The Clover Seed Chalcid Infestation Of Various Alfalfa Varieties In Utah, Reed Charles Bunker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the limiting factors associated with seed production of alfalfa and certain clovers is a small jet-black wasp commonly known as the clover seed chalcid, Bruchophagus gibbus (Boheman). In alfalfa seed producing areas this insect is often referred to as the alfalfa seed chalcid or the alfalfa seed chalcis-fly. In local areas of Utah, farmers often refer to this insect as simply "the fly."

An Inheritance And Linkage Study Of 19 Factor Pairs In Barley, Francis Cheney Lebaron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley, during the past three decades, has been used considerably for the study of linkage groups and character inheritance. The commercial varieties are diploids, having seven pairs of chromosomes. Six linkage groups have been established. According to studies on interchange by Kramer et al. (1954), two linkage groups, formerly designated as III and VII, may be separate arms of the same chromosome. They are now generally considered as one linkage group.

Though more than two hundred characters have been investigated, less than sixty have been assigned relative positions on genetic maps. In many cases, selection for good characters is …

The Influence Of Age On The Cation Exchange Capacity Of Plant Roots, Einard S. Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A yellowing which develops in some plants growing on naturally calcareous soils is called lime-induced chlorosis. The problem is complex, as indicated by Brown and Holmes (1956) and Porter and Thorne (1955). Species and varieties of plants differ in their iron requirements, susceptibility to lime- induced chlorosis, and inter acting soil f actors which affect iron supply (Thorne et al 1950). Chlorosis of plants does not appear, therefore, to stem from a common causative factor. At least a part of this difference has been found to be associated with the plant roots. Thus, through the use of resistant root stock …

Resistance To And Transmission Of Witches' Broom And Comparative Yields Of Alfalfa Varieties In The Uintah Basin, Utah, David Val Glover

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is the most important forage crop in Utah. It is of particular importance to the Uintah Basin, Utah area where alfalfa hay and seed production are major sources of agricultural income. This crop owes much of its popularity to the fact that it will normally produce large yields of good forage on land which is unsuited to more intensive cultivation. In many cases it is impractical to advocate disease control practices which involve extra labor or expense and as a result most diseases of alfalfa, if controlled at all, are controlled by the use of resistant varieties.

During the …

A Manometric Method For The Determination Of Soil Carbonates In The Field, N. A. Polyzopoulos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil survey work the method now generally used to evaluate the carbonate content of the soil in the field is to observe the amount of effervescence that takes place when the soil reacts with dilute acid. The four degrees of effervescence usually recognized are designated by the symbols eo, e, es, ev and correspond roughly to a lime content of 0-0.5, 0.5-3, 3-15, and above 15 per cent, respectively. This, or course, is a very rough estimate and therefore a method is needed for the quantitative determination of carbonates in the field with a fair degree of accuracy. If …

A Study For The Purpose Of Ascertaining The Basic Units Of Instruction For A Unified Drafting Program In Utah High Schools, Elmont L. Bingham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years industrial arts programs have experienced a rapid increase in student enrollment. This is especially true of the drafting area. The extraordinary rate of industrial development within our state is largely responsible for demands for improved training in high school drafting programs.

The apparent inconsistency of course content being taught in Utah high schools indicates a strong need for a unified drafting program that will meet the challenge of our industrial society.

Recently, in a few of our Utah high schools, drafting courses that seem to be effected by industrial influence have been added to the industrial arts …

A Study Of Detachment Of Soil By Artificial Rainfall And Its Relation To The Dispersion Ratio And Water Stable Aggregates For Nine Utah Soils, Pundlik N. Kalbhor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of soil erodibility has become of paramount interest in the last few decades. The effects of soil erosion are serious and extensive and affect nearly all people.

In general, man can do little or nothing about the geologic erosion or natural erosion in which the processes of rock weathering and soil erosion gradually wear down the earth's surface. However, human disturbance of the natural conditions of the land surface often creates accelerated erosion. Fertility of eroded soil is usually reduced measurably and crop yields are lowered considerably as erosion removes seed soil nutrients and cover crops. Loss of …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is part of a series of coordinated research projects undertaken by the College of Education at the Utah State University. The series was under the general direction of Dr. Walter R. Borg working cooperatively with the State Department of Public Instruction and the superintendents of Utah's forty school districts. The superintendents of the state of Utah in recognizing the importance of improved selection systems tor administrators and upon noting the lack of any standard procedure tor selection, asked the Utah State University to accept the problem tor further research. The initial evaluation of the entire problem resulted in …

A Physico-Chemical Study Of Weathering Products In The Payson Soil Series, Lowell A. Douglas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A knowledge of the clay minerals in a particular soil series would aid in the characterization and classification of that soil. The physical and chemical properties of a soil are largely controlled by the properties of the clay minerals in the soil.

This thesis presents the results of a study of the weathering products in a calcareous soil, with a B horizon high in clay content, attempting to determine if the clay accumulation is a product of in situ weathering. It was decided to study soil profiles from within the Bonneville Basin, since a fair estimate of time of in …

The Effect Of Various Levels Of Bicarbonate, Phosphorus, And Ph On The Translocation Of Iron In Plants, Ronald Conrad Doney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Line-induced chlorosis is a nutritional disease affecting many fruit trees, berries, ornamental shrubs, and flowers in Utah and the western United States. In fact, this disease is of wide distribution on calcareous soils throughout the world. Lime-induced chlorosis has contributed to untold economic loss and has challenged the technical ingenuity of plant and soil scientists throughout the world. As yet the exact cause of chlorosis has not been determined; consequently, no permanent cures have been found.

The first symptoms of this disease are characterized by an interveinal yellowing of younger leaves, with the veins remaining green. In more severe cases …

Ferrilegoglobin As An Oxidizing Agent For Hydrazine, Donald B. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The system in which atmospheric nitrogen succumbs to enter Nature's cycle has a yet proven evasive with respect to the actual chemical reactions. At present several types of systems are proposed but their chemical makeup is practically unknown.

Artificial Pothole And Level Ditch Development As A Means Of Increasing Waterfowl Production, Charles H. Lacy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The glaciated prairie pothole country of the Midwest forms a vital segment of the most important waterfowl breeding habitat in North America. Here are hatched three-quarters of all the ducks raised in the United States. During a recent seven-year period the three-state area of Minnesota and the Dakotas produced an average of 4 to 5 million ducks annually (Janzon, 1947). This wetland region which once comprised 115,000 square miles in five states had shrunk to about 56,000 square miles by 1956 (Lynch, 1956). To maintain the present rate of waterfowl production in the face of continued destruction of habitat through …

An Ecological Study Of The Bottom Fauna Of Bear Lake Idaho And Utah, Earl W. Smart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In evaluating the potential ability of a lake to produce fish, probably no single standard is so important as an estimate of the amount of bottom fauna (Deevey and Bishop, 1942).

The study of the bottom fauna of Bear Lake was a part of the investigation of its limnology and fisheries, begun in 1952. This study was sponsored through federal monies made available through the Dingle-Johnson Act. The primary purpose of the study was to examine all the evidence in estimating the fish producing capacity of the lake. Bear Lake is the second largest fresh water lake in Utah but …

Church And State Relationships In Education In Utah, James R. Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study treats a highly controversial area in American education as it applies to the State of Utah. The proper relation between Church and state in the field of education has not yet been settled, nor is it likely ever to be with any finality. In two most recent cases involving the legal issues of Church and State in education ( McCullum vs. Board of Education, 333 U. S. 203 and Zorach V. Clawson, 343 U. s. 306) the United States Supreme Court has written split opinions. The 1956 White House Conference on Education found that religion and segregation were …

A Series Of Five Graded Selections For String Ensemble (Representing Development At The End Of Each Year For Five Years), Raymond M. Haslam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problem involved in this project is the composition of a series of selections for string ensemble. The series is comprised of five sections, each to parallel general achievement of the string students at the end of each year for five years. The degree of advancement one year over another is based not upon the slow student, nor the student who learns extremely fast. Nor is it graded to meet achievement of students who have been afforded a large amount of private instruction over the five years. Rather, it is based upon the growth and development, as observed by the …

Some Chemical Properties Of The Profiles Of Two Soil Series As Shown By Horizons And By Increments, Verle Q. Hale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil classification in this country is based on the system proposed by Marbut in 1920 (2). This system uses eight criteria, one of which is the chemical composition of the soil horizons. Workers in the field of soil survey are depending more and more upon laboratory data to characterize and differentiate soils not only at the series level but also at higher levels of classification where it may be necessary to establish the presence or absence of critical horizons or characteristics. This was predicted by Robinson (16) when he said that laboratory analysis is needed to give "precise physical meaning …

Bryce Canyon Silhoettes, M. David Chugg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is written as an experiment in instrumentation and the factors of technical limitations of the typical Class C high school band. The criteria used in determining the instrumentation and the difficulty of the composition are certain findings with regard to grading of high school band music as found in John Phillip Dalby's Doctoral Dissertation, A STUDY OF INSTRUMENTATION, MUSICAL ACTIVITIES AND TECHNICAL COMPETENCE AS FACTORS IN ARRANGING FOR HIGH SCHOOL BAND.

A Study Of The Sequence Of The Professional Education Program For Elementary School Teachers At Utah State University, Christopher Lee Colston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education, like any other profession, is responsible for constant improvement. The professional teacher education institutions are constantly looking for ways of improving professional teacher education programs. The course sequence of the teacher education program is an area for continual improvement. Every teacher educator has a theory as to what is the best teacher education program and what is the best sequence for this theory program. The literature has revealed very little in the area of a sequence for the teacher education program.

A Critical Survey Of Elementary School Playgrounds In Cache And Box Elder Counties, Thomas Cracas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the fundamental needs of elementary school children is to develop their motor systems by means of physical activities adequately suited to their representative age groups. In so doing, opportunities are provided for sociological and psychological requirements essential in developing a healthy, confident individual capable and willing to accept social and family obligations and responsibilities. This infers that an essential function of the school is to provide appropriate areas, facilities, and equipment for such activities. It also suggests that the playground be an integral element of a modern school.

The purpose of this study was: (1) to construct check …

A Study Of Two Groups Of Superior Students At The Logan Junior High School, Rudgar H. Daines

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Educators have long been aware of the varied needs, abilities, and interests of children. They have tried to provide proper curriculum, materials, and methods to meet the wide range of abilities that exists in every classroom. Despite the attempt of the schools to provide for the particular needs of the individuals, the gifted students continue as a neglected segment in our schools. Because of other pressing educational problems, the awareness of their needs has been somewhat pushed into the background, and only through the present demand for greater leadership in our country and for the optimum use of our manpower, …

The Agricultural Phase Of The Technical Assistance Program Of The United States In Iran, With Special Reference To The Role Of Utah State University, Malek Mansour Esfandiary

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My thesis, while examining the broad scope of American technical assistance in agriculture to Iran, emphasizes the work of scientists and technicians who went there under contract with Utah State University (USAC). I have tried to make this work as complete as available information makes possible.

There are several problems encountered. Some technicians were reluctant to make comments which might appear to be critical of either the American administration or the Iranian government-cultural climate; some did not receive my letter probably because of a change of address. Reference materials were scarce. In most cases it was almost impossible to separate …

The Effect Of Certain Fluoride Sprays In The Production Of Soft Suture On Peaches, N. V. Narayanamoorthy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pollution of the atmosphere and its potential deleterious effects on health, industry, agriculture and natural resources are causing grave concern in many parts of the world. In the past century there has developed in the fields embraced by physical and biological sciences a considerable knowledge of theoretical and applied information, serving as a versatile tool in combating such problems. Air pollution problems seem to have gained much attention with the rapid development of various industries in major parts of the world. Rural and urban areas adjoining these industrial locales are confronted with the dangerous overall problems of air pollution. Evidently, …

Chlorophyll And Productivity In A Mountain River, William J. Mcconnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigation of primary production in streams and rivers has lagged behind similar investigations in marine and lacustrine environments. Recently, however, Odum (1956) has demonstrated methods that allow the estimation of productivity of most moving waters. For reasons discussed later in this paper, Odum's method is not satisfactory for shallow, very rapid rivers as typified by Logan River. The present investigation then was primarily an exploration of a method possibly applicable to measurement of productivity in shallow rapid rivers.

Investigations of phases of the ecology and distribution of the main contributors to primary production, the benthic algae, was a necessary corollary …

Geology Of The Northern Part Of Wellsville Mountain, Northern Wasatch Range, Utah, Stanley S. Beus

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wellsville Mountain forms the extreme northern end of the Wasatch Range in northern Utah. It lies at the western margin of the Middle Rocky Mountain province and is bordered by valleys of the Basin and Range province. Many geologic investigations have been made in this region. Much of the Wasatch Range has been studied and mapped as well as parts of the Bear River Range, east of Cache Valley, and the Malad Range which extends north from Wellsville Mountain; however, the geology of Wellsville Mountain has not been studied or mapped in detail. Some reconnaissance mapping has been done and …

The Phytoplankton Of The Logan River, Utah, A Mountain Stream, William J. Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The voluminous limnological literature contains few studies of mountain streams. Though there are a few papers on the benthic algae (see Budde 1928, Raabe 1951) only Pennak (1943) reports year-round quantitative data on the phytoplankton. Brinley (1950) gives some phytoplankton information in a summer study of streams in Rocky Mountain National Park.

Quality Evaluation Of Deep-Fat Fried Peas, Wattana Sathiraswasti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dehydration is perhaps the oldest method of preserving fruits and vegetables. However, it is still an important method of preservation. During World War II, efforts were geared to investigate the possibilities of such newer dehydrated foods as powdered eggs, tomatoes, and potato granules. Since then many new products are flooding the market every year. The use of dehydrated products has increased primarily because they usually require less space and have longer shelf life, and at the same time they have much more concentrated nutritive value than fresh, canned, or frozen foods. Hence, they can easily be adopted for military rations. …

A Study Of Cheese Spreads And Dips, Grant M. Steed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Each year in the State of Utah, thousands of pounds of a number of varieties of bulk and packaged cheese are returned to the manufacturing plants from the stores and other distribution points. The main reasons are: broken wrapper or rind, crushed or otherwise mutilated package, and mold development.

At the present time much of this cheese is shipped out of the state for processing. The remainder is sold at drastically reduced prices. If this unmarketable returned cheese were changed in form with good consumer acceptance the industry would experience a real savings.

The Effect Of Variety, Harvest Time, And Brine Separation On Thiamine, Riboflavin, And Niacin Contents Of Green Lima Beans, Prasertsri Dee-Ananta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increasing importance of the lima beans as a substantial cash crop for the growers or farmers and as a quality food for the consumer has initiated many investigations directed towards improving its quality as a vegetable crop. Lima beans are well suited for processing; hence, studies of the quality of different varieties in relation to time of harvest have been made. Host processors are in agreement that the beans attain maximum quality before they are fully mature. After that, the yield and size increase whereas the quality decreases.

The Development Of A Dietary Manual For The Small Hospital, Blanche Z. Madsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An increased amount of emphasis is constantly being placed on the standardization of diets where group feeding is involved. Especially is this true in the hospital where food is an essential part of the medical treatment of the patient. The directing personnel responsible for the diets for any hospital situation where a dietitian is employed, are the doctors who prescribe the diet orders and the dietitian who interprets them.

The Effects Of Various Nitrogen And Moisture Levels On The Production Of Silage Corn, Grain Corn, And Sweet Corn, Donald M. May

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many experiments have been conducted measuring the effects of nitrogen rates, moisture, or time of application but few combined all three in one experiment. The object of this investigation is to study the effects and interactions of nitrogen fertilizer, moisture, and time of application on silage corn, grain corn, and sweet com. The effects of these factors should be shown by changes in yield and quality of the crop.
