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 …

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 …

Coupled with the increased use of nitrogen there has come about an increasing awareness of the problem involved in the use of nitrogen fertilizers.

A Descriptive Summary Of Various Band Booster Groups In Southeastern Idaho And A Study Of Their Benefits To The Schools, Melborne Roberts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Within the last 30 years the music departments in the schools of the Southeastern Idaho areas have grown tremendously. With the mushrooming of the band programs within these music departments many problems appear. They arise primarily from inadequate funds.

In order for the band systems in this area to function properly, the problem of finances must be met by some means other than entirely through the funds allocated by local school boards.

Local boards of education frequently do not have sufficient funds to meet such needs as transportation for band tours and trips to the district and state festivals. Large …

The Possible Competitive Position Of Utah Milk Concentrate On Selected Western Markets, Richard S. Magleby

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the last two decades, Utah's market milk industry has changed from one of local processing and distribution by small-scale plants to one of state-wide distribution by large-scale dairies. At present, four large producer cooperatives control most of the state's market milk and six large processing plants accounts for more than 80 percent of the state's fluid milk sales.

Along with centralized processing and distribution has also come some centralization of production. Statistics recently published by Utah State University show that in 1957, 56 percent of the market milk produced in the state came from the five counties of Cache, …

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 Effect Of Captan, Demeton, And 4(2,4-Db) On Alfalfa Growth And Seed Production, Daniel M. Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The widespread use of chemicals for the control of diseases, insects, and weeds in the production of alfalfa seed has caused concern with regards to what effect these materials may have on the inherent reproductive potential of the plants. It has been reported that captan (N-(trichloromethylthio)-4-cyclohexene-1,2-dicarboximide) has both a morphological and physiological effect on some plants. The action of this chemical with regards to alfalfa reproduction has not been reported. Demeton (0,0-diethyl 0(and S)-2-(ethylthio) ethylphosphorodithioate) is another chemical used in alfalfa seed production for which the direct effects on reproduction have not been studied. Adverse effects have been reported on …

An Economic Analysis Of Selected Problems In Processing Sour Cherries, Reed D. Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Red sour cherries have been a dessert item for Americans since long before George Washington chopped down the cherry tree. In the past twenty years production of sour cherries has increased at a faster rate than population. Since 1938 population of the United States has increased approximately 43 million, a 25 percent increase, whereas sour cherry production has increased approximately 78 million pounds, a 38 percent increase. This trend is expected to continue in the future, in fact, according to a Michigan survey the production of sour cherries in relation to the population will increase more in the future.

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.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the beginning of history the wool of sheep has been used by the human race. Its chief use has been and still is for clothing. Also, it is widely used for blankets, upholstery, carpets, and numerous other products.

The wool industry is important to the state of Utah, which was the sixth largest producing state in the United States in 1958. Wool growers in Utah received approximately $7,897,000 in sales proceeds and government payments for wool sold during the 1958 marketing year (12).¹

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).

A Comparison Of The Salt Hardiness Of Barley, Petunia, And Tomato When Grown In Saline And Nonsaline Substrates, James Louis Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The excessive accumulation of salt in the root zone of plants is a problem which is widespread in area, increasing in magnitude, and limiting in its effect upon productivity. Accumulation of salt in the rhizosphere has an effect upon moisture availability for plant use, the nutritional balance of the essential elements, and causes a reduction in plant growth with toxicity often resulting. When plants grow on substrates high in salt, the salt content of the plant also increases. This uptake of salt often results in changes in the morphology of the plant. Accumulation of salt within the plant cells interferes …

Time Interval Required To Measure Effects Of Herbicides On Canada-Thistle And Field Bindweed, Charles Ralph Whipple

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Embryo Sac Development Of An Intergeneric Hybrid Between Lycopersicon Esculentum Mill. And Solanum Lycopersicoides Dun., Ray William Bills

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the search for sources of resistance to the curly top virus disease of tomatoes (Lycopersicon esculentum), it was found by some investigators that certain species of the genus Solanum express an apparent immunity to the disease. It would be desirable to transfer the resistance expressed by the genus Solanum into the genus Lycopersicon. The major problem to the plant breeder becomes one of obtaining a compatible F₁ hybrid between the Lycopersicon and Solanum genera through which genes controlling resistance may be transfered to Lycopersicon. In 1951, C. M. Rick reported a successful cross between …

Observations Of Pituitary Hormone Injections And Ripening Of Fish, D. K. Kaushik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A dependable source of quality fish spawn is a fundamental prerequisite for fish culture development. This is especially important inasmuch as most of the cultivable species do not breed in confined waters. Also, sport fisheries are gaining greater popularity, and subsequently the fish supply is being taxed. Still another need for fish spawn is in the ever increasing demand for bait minnows. Also, the construction of more and more dams has resulted in insurmountable obstacles for ascending and descending fish, which may ultimately result in complete destruction of some fisheries. Thus some measure of artificial propagation will have to be …

Effects Of Beta Rays, Gamma Rays, And Hydrochloric Acid On Tubers Of Jerusalem Artichoke, Subhi Al-Sammarai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Levulose (D-fructose, fruit sugar), C₆H₁₂O₆ is a white crystalline ketohexose. This sugar has distinctive properties which make it of commercial interest. It is more costly than ordinary table sugar (sucrose). Levulose is characterized by a high degree of sweetness (6), great solubility (20), and medical usefulness when administered intravenously. Joslin (21) and Root and Baker (32) found levulose to be of great value in the treatment of diabetes. According to Daniel (8), it is assimilated and oxidized more quickly than sucrose, supplying the necessary energy requirements for the human system. Additional uses of levulose have …

Straddling the Continental Divide, from the Chuska Mountains t o the San Juan and Little Colorado rivers, mostly in Arizona, but partly in New Mexico and Utah, lies 23,574 square miles of desert; home to the estimated 75 to 90 thousand Navajo Indians. Unable to more than eke out a bare existence in a barren land where almost 30 acres of range are needed to sustain one sheep, unprepared after generations of isolation and neglect to leave this reservation for areas where a decend standard of living can be had, the Navajos, since 1950, have been the object of a …

A Study Of The Reasons For Failure On The Job Of Some Graduates Of Intermountain School, Lewis J. Fish

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

They learned something of our American way of life and enjoyed it enough to want to share in it. They knew that to be able to compete with others they would have to get an education and be able to speak English. When these veterans and defense workers returned to the reservation after the war, they started a movement to get the children into school. This movement grew until 91 percent of all school age children were in school in 1957 compared with 32 percent in 1945 when the movement started.
