Economics Of Farm Flock Sheep Production In Northern Utah, Bruce E. Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout the history of mankind, sheep have played a very important and unique part in the economies of the world. They have been a source of meat, milk, skins and fiber. They have become adapted to nearly every kind of husbandry, from nomadic types to intensively managed flocks on small farms and have thrived under nearly all climatic conditions, ranging from sub-artic regions of Greenland to hot areas of the Mediterranean countries; from desert areas of Africa to wet lowland of England.

The Influence Of Nitrogen And Phosphorus Supplements On The Composition Of The Ruminal Ingesta Of Sheep Grazing Desert Range Forage, James G. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Approximately 46 million acres or 88 per cent of the land area of the state of Utah has been classified by Reuss and Blanch (1951) as "range land open for grazing." Although some of this area cannot be grazed because of inaccessibility, lack of water, poison plants, and similar factors, it is estimated that some 40 million acres or 78 per cent of the total land area is available for grazing. Most of this grazing land is federally owned (73 per cent), while only 22 per cent is privately held, and 5 per cent is state owned.

Land Tenure Problems In Iran, Jalil Mahmoudi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Land tenure problems throughout the Middle East and most of the underdeveloped countries of the world are considered by competent international organizations and many students of world problems as one of the greatest contributing forces to social unrest and a barrier to economic development.

When the United Nations' General Assembly at its fifth session in 1950, had under discussion the problem of land reform in many underdeveloped countries, the consensus of opinions were that the conditions affecting land reform reduced agricultural productivity and were a major cause of low standards of living for the populations of those countries. The General …

The Influence Of Soil Compaction Upon The Thermodynamics Of Soil Moisture, James E. Box Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The retention of water in soils is a very interesting subject. Soil-water research presents a great challenge to research workers. The challenge is broad in scope and extends from the field problems of large irrigation projects to the atomic scale of the solid-liquid interface.

If scientists are going to describe scientifically soil-water relations, they must ultimately utilize the instruments of science and the language of mathematics. To the end of the latter the mathematics of thermodynamics has been applied in these studies of water retention in soils.

Phosphorus Status Of Genola Soils In Utah, Warren E. Bendixen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With increasing pressure on economical production of crops, more fertilizers are being applied to the soil each year to increase crop yields. Economical production of crops with applications of fertilizer requires an evaluation of the essential elements of the various crops so applications of fertilizer will not exceed the law of diminishing returns.

Because varying soil, moisture, and climatic conditions influence the response to added fertilizers, some workers (18, 26, 38) have contended that the only reliable way of determining the fertilization needs of a crop is to conduct a trial on the particular farm. The length of time involved …

Economics Of Managing State-Owned Grazing Lands, Lowell Ray Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Range land is an important resource in Utah's economy. Of 52.7 million acres of land in Utah about 78 percent is used for production of range livestock (14).¹ In 1958, cash receipts of range livestock amounted to 62.7 million dollars, or 38.8 percent of Utah's total agricultural cash receipts (19).

Of total land within its boundary, the state owns 2,723,157 acres, or 5.17 percent (32). The state legislature has designated the Utah State Land Board as the responsible agency for administering this land to provide income for various state institutions.

The people of the state of Utah are required …

The Mineral Content Of Various Sections Of Some Plants As Influenced By Conditions Associated With Lime-Induced Chlorosis, Hyrum Del Var Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The so-called "lime-induced" chlorosis has been recognized for many years as a problem where plants are grown on calcareous soils. The characteristics associated with lime-induced chlorosis are the same as those associated with iron deficiency chlorosis--interveinal yellowing of the leaves at the meristemic region combined with reduced vigor of the plant as a whole. Lime-induced chlorosis is unique in that the iron content of both chlorotic plant and the soil do not always show a deficiency in iron when chemically analyzed. This leads to the theory that iron is inactivated in both the soil and plant.

Although no single factor …

Economics Of Controlling Tall Larkspur, Lavar M. Richman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The production of livestock in Utah is important to the economy of the state. The economic life of many communities throughout the state depends on income from livestock. Cash receipts from range livestock were $62.7 million or 38.8 percent of the total from agriculture in Utah in 1958 (18).

An Analysis Of The Differential Responses Of A Group Of Nursery School Children To A Variety Of Musical Presentations, Eva Louise Godfrey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problem of what kinds of music provide the most meaning for the young child has long been a concern of the author. It arises not only out of close experience with young children, but also out of a concern for the responsibility of providing them with meaningful aesthetic experiences. From this background of experience the problem is not purely an academic one. Its first and ultimate concern is an experiential one. Because it arises out of this particular background, the analysis of the problem and its study is less concerned with academic and scientific validity than might otherwise have …

Effect Of Anions On The Sodium Adsorption Capacity And Electrophoretic Mobility Of Sodium Saturated Utah Bentonite, Theron G. Sommerfeldt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sodium saturated Utah bentonite was equilibrated in several concentrations of various sodium salt solutions. The effect of anions on the amount of sodium adsorbed was determined. The effect of anions on the electrophoretic mobility of the clay was also studied. The results are reported herein.

Anions, are generally considered, in the field of surface chemistry, to have no influence on the amount of cations adsorbed or the electrophoretic mobility of negatively charged colloids (5, 10, 28, 41). There is evidence (2, 7, 24, 26, 27, 33) to indicate that anions sometimes have an appreciable effect. If anions influence the amount …

The Effect Of Temperature And Moisture On Nitrification Of Applied Ammoniacal Fertilizer In A Noncalcareous Soil, Merwin Allen Stevens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of nitrogen in world agriculture has been known for many years. But in the past few decades the enormity of the problem of nitrogen economy has been recognized. Along with the recognition of this problem there has developed a great increase in the use of nitrogen fertilizers. Coupled with the increased use of nitrogen there has come about an increasing awareness of the problem involved in the use of nitrogen fertilizers.

Influence Of Compaction And Freezing On The Structure And Permeability Of Some Selected Horizons From Northern Utah Soils, Samir Ramzy Nagmoush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Frequently, in evaluating plant deficiencies, one considers only those soil factors which are associated with the fertility of the soil-- mainly the levels of phosphorus, potash, nitrogen, and organic matter. A certain level of nutrition is essential for plant growth, but in order for the nutrients to exert their maximum influence on the productivity of the soil, it is equally important that a good soil environment be provided and maintained. A good environment requires that good physical conditions of soil, sir, and water be in balance.

The Influence Of Temperature On The Impedance To Water Flow Through Plants, Royal Duane Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This era has been termed the atomic or space age. The greatest concern of most people seems to be centered around survival from the destruction and suffering that might be caused by atomic and nuclear weapons. However, along with this, the world is confronted with perhaps a greater disaster--a potential calamity seldom realized by most people, yet a problem which grows more serious in the world each year--a tragedy which would probably be worse than destruction from nuclear weapons. This encroaching catastrophe is starvation.

Even today the majority of the people in the world do not have enough food. Each …

The Use Of Tetrazolium As A Measure Of The Salt Tolerance Of Alfalfa, Daryl A. Freter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The task of obtaining and selecting plants which may not only survive under salty conditions, but grow and produce satisfactory yields is varied and complex. It is becoming necessary to select and breed crops for salt tolerance. Plants can be grown in artificially constructed salt basins to test their individual salt tolerance, but this takes time, at least one year. It would be desirable to develop a rapid test to determine the salt tolerance of a given plant. The use of a dye in conjunction with a series of salt solutions has been suggested for determining the salt tolerance of …

Moisture And Temperature Effects On The Transformations Of Nitrogen From Applied Ammonium Sulfate In A Calcareous Soil, John Keith Justice

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen has commonly been a deficient element in the cultivated soils of the world since the beginning of agriculture. The general acceptance of the practice of using manures as a means of increasing plant growth, as shown by the records of ancient civilizations, attest to this fact. Since the time of von Liebig there has been an increasing awareness of the importance of this deficiency in soils. As a result of a better understanding of the problem and the increasing availability of commercial forms of nitrogen, a rapid increase in the use of nitrogen fertilizers has taken place in the …

Prediction Of Academic Success In The College Of Forestry, Ronald Skeen Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The College of Forest, Range and Wildlife Management (hereafter referred to as the College of Forestry) at Utah State University has been concerned for some time with the problem of selecting from the applicants to their school the ones whom they think will be able to complete the requirements for graduation. The large number of freshman students placed on probation at the end of the fall quarter and of succeeding quarters each year fives some idea of the magnitude of the problem. It is not unusual for 40 or 50 percent of the entering freshmen to be in this category.

Use Of Gamma Radiation, Chemicals, And Packaging Films To Control Post Harvest Diseases And To Extend Refrigerated Life Of Strawberries And Cherries, Gerald M. Cooper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years there has been a considerable amount of work done on developing chemicals that would inhibit mold growth when applied to fresh fruit, and at the same time, be acceptable to man when taken orally. This would save many thousands of tons of fresh produce that are lost each year by spoilage before it ever reaches the consumer. Along with the development of new chemicals to inhibit mold growth there is a substantial amount of research being done on developing a packaging film that will prevent recontamination of the produce, at the same time allowing the passage of …

Studies On Acceptability And Refrigerated-Life Of Certain Gamma-Irradiated Fresh Strawberries And Cherries, Norma Ward Pierson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

From the beginning of time, the history of man has been his struggle to obtain food. After many thousands of years, this is still a major problem which confronts the peoples of the earth. Although much food is available on earth, a great deal never benefits mankind because of deterioration and spoilage. Various kinds of spoilage cause a million tons of grain to be wasted each year. Man has learned to control and overcome some of these destructive forced through a variety of methods of food preservation. Some forms of preservation such as drying, salting, and so forth, probably have …

The Influence Of Soil Moisture Suction And Evaporative Demand On Actual Evapotranspiration And Yield Of Alfalfa, Bozorg Bahrani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Evapotranspiration has been defined as the combination of evaporation of water from the soil surface and transpiration of water by vegetation. If the ground is well covered by plants, most of the water is lost by transpiration of water directly from the plant tissue, rather than by evaporation of water directly from the soil surface. The term consumptive use is synonymous with evapotranspiration.

A Study Of The Parasites From Rainbow Trout Of A Commercial Fish Farm In Cache Valley, Utah, Kenneth L. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the biennial period July 1, 1956 to June 30, 1958 the 12 state fish hatcheries in Utah produced and stocked in the waters of the state 20,092,902 fish weighing a total of 1,528,787 pounds, at a cost varying between 69 and 75 cents per pound. The cost figure depends upon what expenditures are included (Don Andriano, 1960). A substantial mortality occurs at the fish hatcheries in the state of Utah. The determination of the cause of any given loss is complicated by a number of factors. This is especially true of losses which may be due secondarily to parasites …

Chemical Control Of Spoilage Of Dates, A. Razak Almandil

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dates are typically a fruit of the subtropical arid regions of the world and are native to the valley of the Euphrates.

Analysis Of Selected Problems Of Home Management House Students, Alta Geniel Mcconkie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Traditionally, home economics majors and foods and nutrition majors in most colleges and universities have been able to bring their professional theoretical background to a climax with a practical living experience. This has been the policy at Utah State University, fulfilled in Household Administration, Course No. 150. Although the students entering this course are products of different backgrounds and cultural habits, it is assumed that their common home economics background in the University would allow them to manage a home efficiently. For many, however, this living experience requires a substantial adjustment. In some cases this experience of residence in the …

Self Evaluation Of A Selected Group Of Teen Marriages, Margaret L. Stone

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The statistical trend toward an increasing number of early marriages in the United States is causing concern for parents and community officials (21). The average age of marriage has been declining since 1890. Half of the girls are now married by the time they are twenty and half of the men by the time they are twenty-three (13). In a study made by Landis (20) of marriages in California high schools, 90 percent of the senior high schools reported one or more student marriages. Similar statistics have been reported in New Mexico (16) and Oregon (18). Research has pointed an …
