The Influence Of Some Alkali Salts In The Presence Of Various Concentrations Of Calcium On The Growth Of Sporobolus Cryptandrus, Vaughn A. Clayton May 1942

The Influence Of Some Alkali Salts In The Presence Of Various Concentrations Of Calcium On The Growth Of Sporobolus Cryptandrus, Vaughn A. Clayton

Theses and Dissertations

This study deals with the reactions of Sporobolus cryptandrus to various concentrations of Utah's most common alkali salts. Its purpose is to determine the effects of various concentrations of sodium chloride, sodium carbonate, and sodium sulphate on the growth and fruiting of Sporobolus cryptandrus, and to determine to what extent, if any, various levels of calcium exert a protective influence against the toxicity of these three salts. In addition to the experimental work a field of study was conducted for the purpose of determining the concentrations of total salts found in soils supporting a good growth of Sporobolus cryptandrus.

For decades man has been interested in selection and hybridization of crop plants, but it has not been until in comparatively recent years that anything of importance has been done toward the improvement of perennial forage grasses.


A Study Of The Ring-Necked Pheasant (Phasianus Colchicus Torquatus Gmelin) In Northern Utah, William T. Mckean May 1942

A Study Of The Ring-Necked Pheasant (Phasianus Colchicus Torquatus Gmelin) In Northern Utah, William T. Mckean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Purpose of Study. The ring-necked pheasant (Phasianus colchicus torquatus Gmelin) is well enough known to need no introduction. It is at present undoubtedly the most abundant and most important gallinaceous game bird in northern Utah. Its abundance and its occurrence in agricultural areas has stimulated much general interest. Yet, aside from two food habits studies, both conducted in Utah County, no intensive research has been made into its ecological relationships or its general life history in Utah.

In order to formulate sound management plans for the pheasant in Utah, the Utah Cooperative Wildlife Research Unit has felt the need …


Competition Of Western Wheat Grass With Relict Vegetation Of Prairie, J. E. Weaver May 1942

Competition Of Western Wheat Grass With Relict Vegetation Of Prairie, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Many profound changes in mid-continental grasslands have resulted from the recent extended drought. In the prairies of eastern Nebraska, Kansas and South Dakota, the earlier continuous stands of bluestem (Andropogon scoparius and A. furcatus) have often been greatly fragmented and now occur as relict patches a few square feet to many square rods in extent. Loss of approximately 95 per cent of little bluestem has left the prairie cover very open. Over large areas, except for weeds and a few surviving grasses and forbs, the soil was bared (Weaver, Stoddart and Noll, 1935; Weaver and Albertson, 1939). Grasses …


A Study Of The Sanitary Quality Of Drinking Water In Rural Districts Of Crawford County, Kansas, Kenneth Andrew Mcclure May 1942

A Study Of The Sanitary Quality Of Drinking Water In Rural Districts Of Crawford County, Kansas, Kenneth Andrew Mcclure

Electronic Theses & Dissertations

This study involved the testing of seventy-six wells and thirty cisterns in representative rural districts of Crawford County, using methods specified by the American Public Health Association in the eighth edition of Standard Methods for the Examination of Water and Sewage.

The results of the tests showed that only fourteen of the 106 wells and cisterns tested did not yield Escherichia coli. Of the ninety-two polluted drinking water supplies twenty-seven were from cisterns, while sixty-five were from wells. Of these sixty-five only five of the fourteen deep wells in the group showed evidence of contamination.

These findings seem to warrant …

Stem Blight Of Alfalfa In Utah: A Complex Of Two Distinct Diseases, William E. Rader May 1942

Stem Blight Of Alfalfa In Utah: A Complex Of Two Distinct Diseases, William E. Rader

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1908, Sackett described for the first time what appeared to be a new bacterial disease of alfalfa in Colorado. To this particular disease he applied the name “stem blight" and attributed the cause to a bacterium, Pseudomonas medicaginis n. sp. For some two decades or more Sackett's work on this disease was accepted. During this time stem blight, which was first thought to be indigenous to the western United State, was reported from nine states east of the Rocky Mountains. In 1933, Johnson and Valleau described a disease of alfalfa, characterized by stem lesions very similar in appearance to …


Investigations Of The Fishery Of Fish Lake, Utah, Vaughn D. Madsen May 1942

Investigations Of The Fishery Of Fish Lake, Utah, Vaughn D. Madsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fish Lake, which is located in Sevier County, Utah, is considered to be one of the most productive lakes in the intermountain regions. It is visited annually by thousands of fishermen from Utah and surrounding states. In 1934, a thirteen day check made by the Utah Fish and Game Department showed that anglers caught 17,521 fish with a total weight of 13,844 pounds, and spent a sum of $27,246.21 on expenses.

Because of the great recreational value of Fish Lake, chiefly as a fishing resort, it is desirable to find out whether or not any great change has taken place …


The Scientist's Concept Of The Physical World, Willard Gardner Apr 1942

The Scientist's Concept Of The Physical World, Willard Gardner

Faculty Honor Lectures

To those who are aesthetic, there is perhaps nothing more inspiring than a beautiful sunset, with brilliant colors above the horizon and with banks of dark clouds above, set in the deep blue of the heavens, or the brilliant hues of the rainbow forming a halo about the majestic mountain with its coat of green, purple, brown, or gray. By these things are the emotions stirred.

The physicist too is emotional but he.is also at times realistic. He becomes sentimental but he also seeks to explain the behavior of nature. By means of devices and instruments his perceptual world is …

Grain Prices Received By Farmers Fob Vermillion, South Dakota, Weber Peterson

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

The series of grain prices here presented are calculated from records of terminal market prices by deducting freight charges. In the absence of actual historical local price data this will serve many of the same purposes, subject to the limitations discussed on the inside back cover page. People interested in agriculture and efficient farming are very much concerned about prices. Unlike producers of branded products, farmers have been unable individually to control market prices through control of production. Since individual farmers have found that, in general, prices have been determined by forces beyond their control they have attempted to increase …

One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh Apr 1942

One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to add appreciably to the data available on the metabolism of calcium, phosphorus, iron, copper, and nitrogen of young women on their customary self-chosen diets. It was planned to use the figures for the retentions or losses of these dietary essentials which occurred at various levels of intake to determine the requirement of the subjects and to evaluate the adequacy of present adult dietary standards for young women. The fact that the girls were living on self-chosen diets warrants emphasis. A large proportion of the subjects were doing light housekeeping and brought much of their …
