Studies In Iron Chlorosis Of Leaves, Narayan Gunderao Perur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Normal healthy growth and development of plants is controlled by certain factors known as factors of plant growth. They are soil, climate, and plant inheritance. The soil contains many nutrient elements needed by plants both in macro and micro quantities. Iron is one of the essential elements required by plants in small amounts.

When plants are starving for any of the essential nutrients, characteristic symptoms usually appear as certain abnormalities, discoloration and deformation of leaves, fruits, and other parts. The deficiency symptoms, though not easily recognizable in some cases at the beginning, are quite apparent in advanced stages of plant …

A Political Study Of Federal Aid To Education At Utah State University, Richard Yates Merrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the present-day world of change, every time we pick up the paper we read of something new in our society. We now have new rockets, new satellites, new computers, and new methods or destruction. There are also many "new" things in the field of education. One of these is federal aid to education. As yet, there seems to be no consensus on the merits of this supposedly new approach to educational finance. Some view it as a kind or plague; others see it as an unmixed blessing. Actually, federal aid to education is quite old and quite common.

The Effect Of The Method Of Irrigation And Fertilizer Application On The Movement Of Nitrates In The Soil, Lavoir A. Banks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally recognized that one of the most important factors limiting crop production is soil nitrogen. Farmers today are using more nitrogen fertilizers than ever before. All indications show that this usage will probably continue to increase. With the expanded use of nitrogen, it has become desirable to increase the efficiency from nitrogen fertilizers. One factor which will affect the efficiency is the position of the nitrogen in the soil in relation to the plant roots.

Hydrogen Bonding Between The Carbonyl Group And Wyoming Bentonite, Robert A. Kohl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The vibrational frequencies of atom to atom bonds within a molecule are a function of the bond energies. Each bond has its characteristic frequency, and most of these frequencies can be detected with the infrared spectrophotometer. When one compound reacts with another or is adsorbed on the surface of a solid, detectable frequency changes or shifts may occur. These changes or shifts yield valuable information about the bonds which are formed or broken.

Relationship Of Certain Environmental Factors To Benthic Fish Densities In Bear Lake, Idaho-Utah, Thomas J. Hassler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The project was initiated in June of 1958 and financed by the National Science Foundation and the Wildlife Management Department of Utah State University.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With an ever increasing fishing pressure on our natural and artificial lakes every measure possible must be taken to preserve the sport for its many thousands of participants.

Hyrum Reservoir is easily accessible to the fishermen of northern Utah. In recent years the lake has offered little in the way of fishing. It is hoped that the information accumulated in this study will help pave the way to a successful stocking program and that Hyrum Reservoir will be one of the productive fishing areas available to Utah anglers.

The objectives of this investigation were:

1. To determine the extent of area …

Interaction Of Riboflavin With Molybdenum, Jacques Tocatlian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum may function as a catalyst in promoting and controlling some of the complex chemical reactions that go on in living systems. The lack of understanding which exists about these reactions is due to their obvious complexity and to the extremely minute quantities of molybdenum involved. Traces of molybdenum have been shown to have spectacular results on the growth of plants when added to certain soils. This metal is also required for the growth of azobacter, the nitrogen-fixing bacteria (1).

Molybdenum has been shown to be present in four enzymes: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4) and aldehyde …

Observations On The Life History Of Channel Catfish, Ictalurus Punctatus (Rafinesque) In Utah Lake, Utah, Robert E. Lawler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The channel catfish, Ictalurus punctatus (Rafinesque), was first introduced into Utah Lake in the summer of 1911, and has since been stocked in the lake on numerous occasions. It has only been in the last few years that the channel catfish has become an important game fish in Utah. As the value of the channel catfish, as a game fish, increased, it has become increasingly important to the state to maintain this species for present and future generations. This study was initiated in 1958 and completed in 1960, and was financed by the Utah State Department of Fish and Game. …

The Effects Of Flouride Ion On Some Blood Constituents Of Rainbow Trout, Salmo Gairdneri, Linnaeus, Richard H. Alger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past quarter of a century there has been considerable investigation into the effects of fluorides on living organisms. It has been well established, as a result of these studies, that both small and elevated amounts of fluorides present in the environment may have a marked toxic effect upon gaining entry into the organism. Much of the research involving fluorides and the living organism has been confined to experimentation with animals, although considerable evidence indicates that plants are also subject to injury if fluorides are present in the atmosphere or the soil.

The great majority of the research dealing …

Life History Notes On The Walleye, Stizostedion Vitreum Vitreum (Mitchill) In A Turbid Water, Utah Lake, Utah, Billy B. Arnold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early in 1952, walleye fry were stocked for the first time in Utah Lake. Subsequent plants were made in 1954, 1955 and 1956. Altogether, over two million fry have been stocked.

By January, 1958, it was felt sufficient time had elapsed for the species to establish patterns of growth, reproduction, food habits and consequent relationships to the new environment. Thus, on January 1, 1958, a Federal Aid to Fisheries project, number DJ F-4-R-5, job T, was initiated. This project was entitled "investigations of Yellow Pikeperch and Channel Catfish of Utah Lake, Utah County." Although the closing date was December 31, …

The Temperature Dependence Of The Drying Of Horizontal Soil Columns, Craig Loren Wiegand

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A consideration of the physical principles involved in evaporative drying of soil indicates that several physical processes might possibly limit the rate of evaporation. These include the rate of supply of energy to the site of evaporation, the rate of transfer of water vapor through the sample or through the atmosphere above the sample, and the rate of unsaturated flow of water to the soil surface or to the site of evaporation.

The Effect Of Nutritional Education On The Food Habits Of High School Students, Gladys C. Hyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

"From the day that Adam and Eve shared an apple in the Garden of Eden, food and the partaking of food have been of infinite significance in the life of man."

There is a growing concern among nutritionists and others about the food habits of teenagers, Although the United States is considered to be the best fed nation in the world, there is an important group of our population, abut 16,000,000 teenagers, who have alarmingly poor food habits.

In this thesis the method is extended to the forecasting for the Blacksmith Fork River, south of the Logan River.

Because the climatological data are not available in the Blacksmith Fork watershed, this thesis also provides a technique for using the available data from adjacent watersheds.

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 …

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 …

Problems Of Navajo Male Graduates Of Intermountain School During Their First Year Of Employment, Joe E. Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the primary objectives of education in the United States is to prepare young people for adult life. They are expected to become a part of the social and civic life of the community, and by working in a vocation to contribute to their own personal welfare and that of the society in which they live.

The above tasks are considered some of the most important and difficult ones facing all youth. If it is difficult for the youth who has had full advantage of the culture in which he lives, it is certain to be much more difficult …

Studies On The Sampling Methodology Of Peas For Yield And Quality, Pratapsinha Chintamani Pendse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pea¹ growers have much at stake in getting high yields of peas of prime quality. The income accruing from a pea crop grown for processors is determined by the yield as well as quality. Therefore the farmers' efforts are directed toward growing such a crop.

Research workers are interested in knowing the yield of peas with known tenderometer values which will indicate the quality of peas. Present methods of field harvesting are costly and time consuming which tend to limit the number of varieties that can be satisfactorily evaluated for trial.

A comparison of sampling techniques with present harvesting …

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 …

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 …

A Comparison Of Internal Bicarbonate Of Some Chlorosis-Resistant And Chlorosis-Susceptible Plants, Ralph Barlow Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron chlorosis has been a srious problem for many years. This physiological disease has occurred so frequently on calcareous soils that it has been called lime-induced chlorosis by many of the workers. Because the western United States has so many soils of this type, the chlorosis problem has been of primary concern. Untold economic losses have been the result of this physiological disease.

Interveinal yellowing of the leaves along with loss of plant vigor and retarded growth characterize the disease. In severe cases die-back of the terminal growth and eventual death of the plant result. No single factor has been …

Motor Truck Transportation Of Cattle In Utah, Loren H. Grover

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The beef cattle industry in Utah is of major importance in the economy of the state. In terms of cash receipts it is the largest single agricultural enterprise. In 1957 cash receipts from the sale of cattle and calves amounted to $38,405,000. This figure represents approximately 70 percent of cash receipts from the sale of all meat animals. It comprises 33 percent of cash receipts from the sale of livestock and livestock products and 24 percent of total cash receipts from farm marketings (2).

The production of beef animals will continue to assume a position of importance in Utah's agriculture, …

Development And Evaluation Of Laboratory Methods For Determining The Nitrogen Supplying Power Of The Irrigated Soils Of Northern Utah, Jerald Ross Wight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen is the most widely needed and the most widely used of the fertilizer elements. Yet, in spite of the voluminous research work of evaluating the nitrogen status of soils, laboratory tests for the purpose of predicting need of nitrogen fertilizer are not very widely used. In general, laboratory tests for nitrogen supplying power have not given satisfactory results. Methods currently employed by a few laboratories can be classified either as biological or chemical. In the former method, the soil is incubated under optimum conditions and the amount of nitrate released over a given period of time is measured and …

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 …

The Effect Of Nutrient Levels In Nutrient Cultures On The Translocation Of Foliar Applied Nutrients, David D. Neher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since man first grew crops on calcareous soils he has probably been troubled with what we today call lime-induced chlorosis. This chlorosis has determined whether he grew certain desirable ornamentals or crops or whether he had to substitute others which were less desirable.

Lime-induced chlorosis is spread world wide. It has been reported in the vine and fruit growing regions of Europe, in the chernozem soils of Russia, and many other areas where the rainfall is relatively low and the soil is relatively high in calcium carbonate. In the United States it most frequently occurrs where the average annual rainfall …

Effects Of Gamma Radiation On Asparagus And Tomatoes, Arthur L. Rivers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since growers are generally unable to produce food the year-round, preservation of available food by the growers and processors has continued to challenge the minds of these men and their scientific cohorts. Even the consumer is subject to this problem and mist rely on those from. whoa he receives food as to its present and eventual condition. Many methods of preservation have been used such as pickling, drying, smoking, canning, and freezing. Most of these preservation methods require excessive handling and/or extensive storage facilities.

An Evaluation Of The Salt Tolerance Of Selected Clones Of Agropyron Elongatum, Jordan G. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt-affected soils make up much of the bottom-lands of the arid and semiarid areas of the western United States and are especially prevalent in irrigated regions. Such soils require special remedial measures, management practices, and salt tolerant crops if they are to have economic value.

A Survey Of The Use Of Standardized Tests In The Junior High Schools Of Weber County, Ashlaug J. Jackson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is evident from the literature reviewed that there is a need for better understanding and utilization of standardized test results. It seems that unless tests contribute to the learning process they are not justifiable. Merritt (12, p. 66) says the main objective of all endeavor is to promote learning. Ultimately, the worth of any activity carried on in the schools has to be judged by the contribution this activity makes toward the improvement of learning. Testing is no exception. In a broad sense, desirable learning has taken place when behavior has been changed in socially approved directions. Testing is …
