Bulk Hybridization Of Smooth Bromegrass (Bromus Inermis), Wayne E. Domingo
Bulk Hybridization Of Smooth Bromegrass (Bromus Inermis), Wayne E. Domingo
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Large populations of controlled hybrids are essential to the most rapid progress in many phases of plant breeding programs. Plant species vary in the ease with which they may be hybridized. Hand hybridization of forage grasses is usually slow and laborious, and the minuteness of the floral parts of most of the species which have perfect flowers renders their hybridization by hand especially difficult and tedious. This difficulty limits the use that forage grass breeders are making of the significant principles of hybridization and thereby retards progress in this phase of plant breeding. Any dependable, rapid technique of hybridization which …
Inheritance Studies And Possible Linkage Relationships In Barley Involving Five Factor Pairs, Freeman J. Byington
Inheritance Studies And Possible Linkage Relationships In Barley Involving Five Factor Pairs, Freeman J. Byington
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Many studies on inheritance in barley have been made, but very little progress has as yet been obtained. Barley in many ways is an attractive plant with which to make inheritance studies. Unlike common wheat with 21 chromosome pairs and few distinct characters, barley has only 7 chromosome pairs and consequently only 7 possible linkage groups and many distinct characters that may be readily recognized. The chief difficulty is that many of these characters cannot be readily classified because a number of factors may be responsible for their production.
The purpose of this project has been to study in considerable …
Trichomoniasis Of The Utah Agricultural Experiment Station Dairy Herd, Rue Jensen
Trichomoniasis Of The Utah Agricultural Experiment Station Dairy Herd, Rue Jensen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Bovine trichomoniasis is a venereal infection that reduces the fecundity of cattle. It is caused by Trichomonas foetus (Riedmuller), a flagellated protozoan which inhabits the genital tract, causing inflammation and partial sterility. Both sexes are susceptible to infection. In females it is usually of short duration and frequently terminates spontaneously following abortion. In males the disease has both acute and chronic stages. During the acute stage the prepucial membranes become inflamed and a muco-purulent discharge develops in which trichomonads are abundant. In the following chronic stage symptoms disappear, but the animal remains a carrier and is a dangerous source of …
Some Factors Related To Student Achievement Of Entering Freshmen At The Utah State Agricultural College, James Francis Day
Some Factors Related To Student Achievement Of Entering Freshmen At The Utah State Agricultural College, James Francis Day
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The need for study in regard to factors related to student achievement and their possible application as guidance devices for entering freshmen in any college is very evident in our modern life. We have only to look at the increasing college enrollments and to the scarcity of positions for college graduates to realize this. In an effort to meet this need, educators should more and more base their practices on the findings of statistical and experimental studies.
That an improvement is needed in the technique used for the guidance of entering students at the Utah State Agricultural College is very …
The Ecology Of Agropyron Inerme On Protected And Heavily Grazed Range Land In Cache Valley, Utah, Wallace R. Hanson
The Ecology Of Agropyron Inerme On Protected And Heavily Grazed Range Land In Cache Valley, Utah, Wallace R. Hanson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
During the past decade much attention has been attracted to the great range lands of the West. The inherently low productivity of these arid lands coupled with abnormal drought and constantly heavy use by livestock because of lack of grazing control, have caused these lands to become greatly depleted over most of the West. That the vegetation on most range land in the intermountain states is depleted appreciably is evident to the careful observer. Undoubtedly the vegetation of much of the range has decreased in quantity, but more serious in many cases is the decrease in quality. Valuable forage species …
A Study Of The Sage Grouse (Centrocercus Urophasianus), With Special Reference To Life History, Habitat Requirements, And Numbers And Distribution, Lynn A. Griner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The sage grouse or sage hen Centrocercus urophasianus (Bonaparte) was formerly the most important upland native game bird of the Western States, but has steadily been declining in numbers over most of its range in recent years. This reduction in numbers has aroused the interest of the conservationists of the nation, who, for the past decade or more, have been proposing that something be done for this game species. In recent years along with this interest of the conservationists, there has been an increasing local interest among the sportsmen of the West, with the result that several groups have become …

A Taxonomic And Ecological Study Of Acridinae Of Utah (Orthoptera-Locustidae), Herald C. Bennion
A Taxonomic And Ecological Study Of Acridinae Of Utah (Orthoptera-Locustidae), Herald C. Bennion
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Orthoptera, especially the family Locustidae, is one of the most important and most interesting orders of insects in the state of Utah. It includes a polyphagus group of great economic importance in the state. The topography and climate of Utah varies from forested alpine slopes to hot arid desert wastes, several life zones being represented. This great variation from desert to alpine in Utah presents a rather unique region for taxonomic and ecological studies of the Orthoptera.
The most familiar representatives of the insect order Orthoptera are the long-horned grasshoppers, locusts, crickets, katydids, and cockroaches. Orthoptera are characterized by Comstock …
The Interests Of High School Boys In Logan, Utah, C. D. Mcbride
The Interests Of High School Boys In Logan, Utah, C. D. Mcbride
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
It is generally conceded by psychologists and educators that interest is the starting point for all learning. Effective application of this principle in educational procedure has, however, proved to be far more difficult than it at first appeared. It has given rise to varying types of schools, teaching methods, programs and practices. The activity program, the vitalized education program, the project method, the problem method, the child centered school, the play-and-learn program, and others have had, and still have, their champions and followers, all flying the banner of Dewey's "Interest and Effort" philosophy.
Teachers and educators generally talk freely about …
A Study Of Hybrids Between Sugar Beets And Mangel Wurzels With Reference To Color Factors And Sugar Content, Boyd Berrey
A Study Of Hybrids Between Sugar Beets And Mangel Wurzels With Reference To Color Factors And Sugar Content, Boyd Berrey
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Preliminary unpublished work at the Salt Lake City Laboratory of the Division of Sugar Plant Investigations, Bureau of Plant Industry, United States Department of Agriculture, indicates that beets showing the Y color factor (9) were larger than sugar-beet types recessive for this color factor (y y). It was suggested to the writer that an investigation be made to determine whether or not yield and sugar content were correlated with color factors in beets. Linkages between the R and Y color factors have been reported by Keller (9), and the results indicate a close linkage between color factors R …
Glaciation In The Logan Quadrangle, Utah, J. Llewellyn Young
Glaciation In The Logan Quadrangle, Utah, J. Llewellyn Young
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
That the higher valleys of the Wasatch Mountains were occupied by Pleistocene glaciers has long been known. King, Hague, and Emmons, geologists of the Fortieth Parallel Survey, the first to undertake a systematic study of any part of the Wasatch Mountains, recognized this fact and their report includes a map which shows in a rough way the extent of the glaciated areas in the Central Wasatch (11 ). In 1909 Atwood (1) made a detailed study of the glacial features of the Central Wasatch in connection with his study of glaciation in the Uinta Mountains. He mapped the deposits of …

Past Trends Of Cooperative Marketing And Its Present Economic Status In Utah, Lamoine B. Christiansen
Past Trends Of Cooperative Marketing And Its Present Economic Status In Utah, Lamoine B. Christiansen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The agricultural interests of the United States and Utah have experienced some trying situations during the past quarter century. Periods of depression followed by periods of expansion and prosperity have resulted in a condition of instability and insecurity in agriculture.
The effect of alternate periods of prosperity and depression in agriculture becomes increasingly important as agriculture changes from self-sufficing to commercialized types of business enterprises. Many of the difficulties inherent in the present complex social and capital structure were of minor significances in the early types of agricultural activities.
Changing conditions in agriculture and in social institutions in general have …
The Feeding Value Of Certain Duck Food Plants Of The Bear River Migratory Bird Refuge As Determined By Chemical Analysis, Dale Clair Christensen
The Feeding Value Of Certain Duck Food Plants Of The Bear River Migratory Bird Refuge As Determined By Chemical Analysis, Dale Clair Christensen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The study of bird feeding problems has become a prominent factor in wild life management. This is true especially with respect to the evaluation of recently established migratory bird refuges. In 1929 the Federal Government assumed control of a large area of land located on the Bear River Bay of Great Salt Lake for the purpose of providing a sanctuary for water fowl. Dykes were built and the areas inside these dykes flooded with fresh water from Bear River. During subsequent years aquatic and marsh plants* developed abundantly and apparently have provided satisfactory feeding and nesting grounds for migratory birds. …

A Critical Analysis Of Methods Of Securing Basic Irrigation Data Used In Water Right Determinations, A. Alvin Bishop
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Agriculture in the Western United States is almost entirely dependent upon irrigation. Irrigation has transformed the desert lands into fertile, producing valleys. It has made possible communities and settlement areas which would otherwise be impossible. Although the achievements of irrigation have been great, there still remains millions of acres of fertile land that will never be reclaimed because there is not available water.
The Northwestern Shoshone Indians, (A) Under Tribal Organization And Government, (B) Under The Eccleastical Administration Of The Church Of Jesus Christ Of Latter-Day Saints As Exemplified At The Washakie Colony, Utah, Joshua T. Evans
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Northwestern Shoshone Indians is the tribe of Indians that inhabited the territory north of the Great Salt Lake comprising the northern part of Utah and the Southern part of Idaho. The Indians have loose boundary lines, yet we can definitely state that this tribe occupied the territory from the Weber river on the South to the Snake river on the North; from Bear Lake and Bear river on the East to Raft river and Goose creek on the West. Their confines would take in Weber, Rich, Box Elder, Cache, and part of Morgan, counties in Utah; and Bear Lake, …

The Plankton Of The Bear River Migratory Waterfowl Refuge, Utah Seasonal Distribution Of Organisms, George Piranian
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the summer of 1932, an investigation of some biological, physical, and chemical conditions at the Bear River Migratory Waterfowl Refuge, Utah, was begun at the Utah State Agricultural College to determine some of the factors governing the biological productivity of brackish-water marshes. Unfortunately, lack of funds made it impossible to continue work beyond the first season.
In 1936, the Wild Life Experiment Station at the Utah State Agricultural College appropriated a fund for a cooperative project between the Station and the Department of Botany at the same institution. This project, planned to be continued by various graduate fellows over …
The Identification Of The Tomato Mosaic Virus Prevalent In Utah, Ross D. Watson
The Identification Of The Tomato Mosaic Virus Prevalent In Utah, Ross D. Watson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Collections of tomato mosaic virus obtained from Utah and California produce a localized severe leaf and stem necrosis on Datura meteloides. After the streaked plant has stood sufficiently long to permit secondary growth to occur, a systemic diseased expression develops in a few of the plants. No reference to a similar development on Datura meteloides following inoculation with the tobacco mosaic virus was found in the literature.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Especially during the last century the health of school children has been a problem of deep concern. Many physical examinations have been given by numerous organizations with the intention of discovering organic disorders that might be detrimental to a child's normal social life. As a result of such study, humanity has generally come to recognize the social and economic costs of ill-health and has embarked on remedial and preventive campaigns to improve the well-being of children. Foundations have been endowed. Free clinics have been established to serve those families whose incomes prohibit them from securing medical services otherwise; county, city …

A Study Of The Equilibria Between Bentonite And The Various Replacing Agents In Alcoholic And Water Solutions, Joel E. Fletcher
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Investigators in soils have long recognized the importance of the colloidal fraction of soil, and also the almost inseparable problem of replaceable bases. It is generally accepted that the replaceable base fraction of a colloid controls to a large degree the physical properties exhibited by it. Volumes of work have been written on the problem of controlling the reactions of this fraction and on studies of the properties exhibited by it when it is saturated with various cations. Each worker has proceeded in his own individual way or followed the example set by some previous worker with specific modifications.
The Microflora Of Milk Drawn Aseptically From The U.S.A.C. Dairy Herd, Lewis W. Jones
The Microflora Of Milk Drawn Aseptically From The U.S.A.C. Dairy Herd, Lewis W. Jones
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Early studies on the bacterial content of milk were made mainly to satisfy the interest of people who wished to determine the various materials that contained bacteris. Soon the value of bacterial counts, as an indication of the general conditions of production, of handling, and of the keeping qualities of milk, became evident and bacterial counts were used to obtain information concerning these problems. Numbers of bacteria in milk have been used also in the studies of the desirable and undesirable changes in milk.
In the last few years our citizenry has been made more conscious of the presence and …

An Economic Analysis Of Farm Tenure In The Uintah Basin, Utah, Glen B. Johnson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Before presenting an economic analysis of farm tenure in the Uintah Basin, it will be helpful to consider some aspects of the historical, economic, and social background of that portion of the region included in this study.
A portion of the Uintah Indian Reservation, which was created in 1861, was opened to white settlement under the homestead and townsite laws on August 28, 1905 after 103,000 acres of farming land had been allotted to individual Indians living on the reservation and 276,000 acres reserved for Indian grazing lands and timber reserve.
Because of the large deposits of asphalt products that …

The Life History Of The Dewberry Fruit Worm Cacoecia Rosaceana (Harr.) In Utah, Merlin W. Allen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this study has been to determine the identity and the life history of certain larvae attacking dewberry fruits and foliage in a few sections of Utah. The dewberry fruit worm as it was called until it was definitely identified the oblique-banded leaf-roller, was first observed by farmers at Granite and Butlerville in 1932. Since 1934 it has been found affecting dewberries in other parts of northern Utah.
This investigation was begun in the spring of 1935 and continued until the fall of 1936, being made possible through the Utah Agricultural Experiment Station, Department of Entomology, and with …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the last decade there has been manifest widespread interest in the development of children. Clinics, social agencies, and schools have made substantial contributions to our knowledge concerning children, their care, training, and growth. This is especially true of the pre-school child. Many studies have been made concerning his learning behavior, factors affecting his eating habits, his emotions, metor skills, intellectual development, and social behavior.
An Analytical Study Of Utah Verse To Determine What Utah Poetry Might Be Recommended For Study In Elementary And Secondary Utah Schools, Lawrence James Sorenson
An Analytical Study Of Utah Verse To Determine What Utah Poetry Might Be Recommended For Study In Elementary And Secondary Utah Schools, Lawrence James Sorenson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study has a primary and a secondary purpose. The primary purpose is to call attention to the question of whether or not Utah verse should be introduced for study into the elementary and secondary schools of Utah. The author does not want to imply that he will give a satisfactory answer to this question. He hopes, however, that this effort will emphasize the question and stimulate thought concerning the same. It seems reasonable to suppose that most of the Utah school officials who are concerned in any way with literary material for school curricula will agree that, if there …

Riding the crest of the torrent of verbal altruism which flooded in the New Deal came a malnurtured little fellow, the consumer - the same timid, mistreated, gullible little fellow with the battered derby hat whom cartoonists have so aptly pictured on the stool peering meekly over the counter at the big bruiser, the producer, who stood behind it. Put now he was to be such rejuvenated personage. The hair shirt in which one writer has so smartly dressed him was to be miraculously transformed into finest armor of an impregnable protective alloy which was to be composed of numerous …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Today the under-privileged are by no means confined to the mentally and physically handicapped. Since 1929 the number has greatly increased because of our faulty economic and social organization. Many healthy men who are both able and willing to work have been forced into idleness because of inability to secure a position. Extension classes in "Mental Hygiene" and "Social Case Work" conducted under the direction of the head of the Sociology Department of the Utah State Agricultural College during 1934-35, decided to make a study of conditions actually existing among Ogden City's victims of the depression, with particular emphasis on …

The Vitamin D And Provitamin D Content Of Some Varieties Of Utah Wheat, Harold M. Nielsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cereal grains were known to be notably deficient in the anti-rachitic principle even before the discovery of vitamin D. Clinicians had associated a type of rickets of infancy, characterized by an over-weight, flabby, bowlegged condition, with a diet consisting mainly of cereals. Mellanby (1) in 1921 concluded that this type of rickets is induced by overfeeding with carbohydrates. He also showed in the same report, however, that oatmeal, although it contains less carbohydrates than the other grains tested, possesses a special tendency toward rachitogenesis.
