Bulletin No. 283 - Range Conditions In The Uinta Basin, Utah, L. A. Stoddart, P. B. Lister, George Stewart, T. Dean Phinney, L. W. Larson

UAES Bulletins

Project 179 of the Utah Agricultural Experiment Station - "A Study of the Agricultural Resources of Utah and their Utilization" - was set up in April 1936 us a state-wide project. The object of this project was to measure by areas the basic agricultural resources of the state and to translate the information collected into a program of more efficient use. The more specific objectives were: (1) classification of agricultural lands of Utah according to present and potential productivity and use; (2) determination of the net productive area of agricultural lands and water supply now available, or which may be …

Bulletin No. 282 - Pioneering In Western Agriculture

UAES Bulletins

A resume of the First Half-Century of Research 1888 - 1938 at the Utah Agricultural Experiment Station including the Biennial Report 1936 - 1938.

The Utah Agricultural Experiment Station in reaching the fiftieth year of its history can look back upon a brilliant record of achievement covering the practical as well as the more fundamental problems of agriculture in this arid state. The difficulties encountered in conquering deserts down through human history have demonstrated the mastery of man's spirit over his physical environment. Man's destiny to multiply, subdue, and replenish the earth cannot be accomplished by enjoying the fruits of …

A Proposed Method For Classifying And Evaluating Soils On The Basis Of Productivity And Use Suitabilities, Arthur Anderson, A. P. Nelson, F. A. Hayes, I. D. Wood

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the object of this paper to present a method for classifying and evaluating the soils as mapped in regular soil surveys on the basis of land types, which are here defined as areas having reasonably similar productivity and use suitabilities. The standards used to differentiate land types will vary according to the desired objectives, but any material difference in yield, or in practices necessary to maintain a desirable level of productivity will justify recognition of land types. The proposed procedure involves a more detailed study of the influence which soils, slope, erosion, and drainage have on specific crops …

Bulletin No. 279 - The Fruit Tree Situation In Utah, A. L. Wilson, A. L. Stark

UAES Bulletins

The fruit industry in Utah is not large when compared with the total production of the United States. The year 1935 was a favorable fruit season for Utah and yet the state produced only 0.54 percent of the United States' apple crop, 1.30 percent of the peach crop, 0.31 percent of the pears, and 3.72 percent of all cherries. Utah does, however, produce between 10 and 15 percent of all sweet cherries. Even though the Utah fruit industry represents such a small part of the national industry, a great many people of the state are dependent upon it, either wholly …

The Chemical Nature And Distribution Of Black Pigment In Soil, William Sherman Gillam

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

As used in this paper, humus refers to that portion of the soil organic matter peptized by four per cent ammonium hydroxide. That fraction peptized by four per cent ammonium hydroxide, precipitated by acids, and insoluble in alcohol, is designated as black pigment. It is called humic soil by many writers.

Root Distribution Of Trees In Relation To Soil Profile, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

One of the pronounced trends in American forestry during the past decade has been the development of a widespread interest in soils. As a consequence to the soil as a part of the environmental complex has been attributed much greater importance than formerly in forest production. In fact, the individual horizons of the soil profile are receiving attention each as a more or less distinct habitat of that highly organized body designated as soil. Just as soil scientists, until recent years, have given inadequate attention to the factor of vegetation in the constitution and development of soils, so too little …

Root Development Of Young Delicious Apple Trees As Affected By Soils And By Cultural Treatments, W. W. Yocum

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The major problem of this investigation was to determine the effects of different cultural treatments and soil conditions upon the depth and lateral spread of the root systems of young Delicious apple trees during the first three years in the orchard. This study was conducted during the years 1932 to 1934 inclusive.

The Influence Of Various Soil Factors Upon Potato Scab Caused By Actinomyces Scabies, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Scab, caused by Actinomyces scabies (Thaxt.) Giiss., is a potato disease of major importance in western Nebraska. Seed treatments are effective in controlling seed-borne scab, but it has been shown that even when healthy or treated seed potatoes are used the disease may be very severe because of infection from the soil. Crop rotation will reduce the incidence of the disease, but the fact that potato scab may cause serious loss in soils never before planted to potatoes indicates that there are numerous factors other than the time interval between potato crops which affect the occurrence of the disease. A …

Bulletin No. 281 - Sorghums Varietal Tests In Utah, R. W. Woodward, D. C. Tingey, R. J. Evans

UAES Bulletins

Sorghums are not grown to any appreciable extent in Utah except in the Virgin River valley in the southwestern portion of the State. No experimental work on sorghum culture had been done prior to 1931 except on the dry land of Juab County near Nephi. Those early tests, discontinued after 1917, indicated that sorghums were poorly adapted to such conditions.

Numerous improved varieties have been produced since that time, some of which are adapted to relatively short growing seasons.

This bulletin will discuss the practicability of growing some of these varieties of sorghum in Utah and their economic value compared …

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 Effect Of Cultivation On Certain Chemical And Physical Properties Of Some South Dakota Soils, Oscar E. Olson

Electronic Theses and Dissertations

Soil Nutrient losses have followed closely in the paths of advancing frontiers in agriculture. Remedies for depletion as the result of overcropping were sought by George Washington, whose interest and investigation of soil nutrient losses probably represent the earliest attention given to land exploitation in the United States, which at the present time has become a problem of national concern. Soil losses have been attributed to a number of causes , among which are cropping, erosion, leaching, burning, and rapid oxidation of organic matter in the soil. Associated with soil nutrient losses, certain significant physical and chemical changes may occur …

Diseases Of Upland Game Birds, J. E. Shillinger, L. C. Morley

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Until recently the diseases of upland game birds received comparatively little specific study, except in a few outbreaks in which serious losses were observed. Though highly destructive, many of these outbreaks were of such short duration that the investigations undertaken were chiefly to learn the cause of death and usually were discontinued when losses were no longer noticeable. It has become increasingly evident, however, that every year great numbers of game birds die of disease, the decreases in their numbers frequently occurring in sections closed to hunting, even though food, cover, and other environmental conditions appear ideal. The disease problems …

The Influence Of Overgrazing On The Density And Number Of Palatable And Unpalatable Desert Forage Plants, John H. Mcguire

Theses and Dissertations

The data for this problem were collected at the Desert Range Experiment Station and on adjoining public domain lands during the summer of 1934, for the purpose of studying the influence of overgrazing on the increase of palatable and unpalatable desert forage plants. A vegetative description of the two areas studied has been prepared and presented.

Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas

UAES Bulletins

A large portion of the agriculture of Utah, outside of the desert range areas, is characteristically heterogeneous rather than homogeneous in character. Marked differences in size of farm, in crops grown, in livestock kept, in yields, and in farm organization occur within short distances. This diversity is due in large measure to differences in soil, elevation, topography, and other physical features and to climatic characteristics such as amount, kind, and distribution of precipitation and length of growing season. The physical and climatic features are the chief determinants of the amount of water potentially available for the irrigation of the crop …

Spruce In The Western Miocene, George F. Beck

All Faculty Scholarship for the College of the Sciences

One of the real surprises in store for us as we began to section specimens of petrified wood from the Vantage and certain other horizons in Central Washington, was the prevalence of a spruce type hardly hinted at in the leaf lists as published for the various sediments of Yakima time (upper miocene?).

Bulletin No. 274 - Influence Of Rotation And Manure On The Nitrogen, Phosphorus, And Carbon Of The Soil, J. E. Greaves, C. T. Hirst

UAES Bulletins

All agricultural plants require carbon, hydrogen, oxygen, nitrogen, calcium, potassium, magnesium, sulfur, phosphorus, iron, and probably traces of other elements for their normal growth and fruition. The growth of farm crops is dependent upon an available supply of these elements, and the extent of growth is governed by the one present and available in least quantity in proportion to the plant's needs. Of the essential elements, all plants secure two (carbon and oxygen) from the air, one (hydrogen) from the water, and the others from the soil. Most soils contain sufficient plant nutrients for normal plant production, with the exception …

Bulletin No. 272 - Transmissibility Of Bang's Disease Among Dairy Cattle In A Utah Dairy Village, D. E. Madsen, O. G. Larsen

UAES Bulletins

For a number of years it has been generally recognized that one of the most satisfactory methods of controlling Bang's disease in dairy cattle is to locate spreaders by means of the agglutination test and to eliminate them from the herd. The success of such a plan in relation to Utah dairy herds was not clearly understood because of the physical farm set-up peculiar to many communities in this state. The village of Hyde Park where this study was made is organized on such a community basis. Usually, a house and livestock buildings are constructed on the town lot, consisting …

Bulletin No. 266 - Comparative Size Of Rural And Urban Utah School Children As Determined By The Weight - Height - Age Relationship, Almeda P. Brown

UAES Bulletins

The problem investigated was as to whether significant differences occur in size of rural and urban Utah school children. Through cooperation of school officials weight-height-age measurements were secured for the following groups of children from 6 to 15 years of age.

Bulletin No. 268 - Alfalfa Seed Investigations And Other Crop Varietal Studies: Millard County, Utah 1929 To 1933 (Inclusive), George Whornham

UAES Bulletins

The Delta Area, in which most of the alfalfa-seed investigations and crop studies reported in this bulletin were conducted, is located in Millard County which is in the west-central part of Utah. This area lies in the Sevier Desert, within the eastern boundary of the Great Basin in the northeastern part of the county.

Parts of the area, particularly the farming sections near the towns of Oasis, Deseret, and Hinckley, have been among the oldest and most consistent alfalfa-seed producing sections of the United States. The peak of alfalfa-seed production in Millard County was reached in 1925, when approximately 14,000,000 …

The Abortion Of Essential Organs In The Imperfect Flowers Of Benzoin Aestivale, Norris M. Paulson

Electronic Theses and Dissertations

There have been a number of investigations dealing with the abortion of essential organs in the imperfect flowers. Ulvin submitted a paper on Abortive Stamens and Carpels in Lychnis alba, Simon described stamen and carpel abortion in Cucumis stativus, Schaffner was able to control sex expression in Arisamea triphyllum and secure sex reversal in Cannabis stiva, Bessey determined the relationship of sex to the age of pollen in Cannabis sativa.

The Tympanis Canker Of Red Pine, John Raymond Hansbrough

Yale School of the Environment Bulletin Series

A new disease of red pine has recently been found in southern Connecticut, Rhode Island, eastern Massachusetts, western and central New York, northern New Jersey, eastern Pennsylvania, central Ohio, and southern Michigan. It is of serious consequence only on plantation-grown red pine, but it also occurs occasionally on eastern white pine. On the former host it is characterized by axially elongated, annual main-stem cankers which are always centered at the nodes. Infection takes place through adhering lateral dead branches and the growth of the fungus after it gains entrance to the stem.is usually very rapid-Le., cankers up to three feet …

Bulletin No. 258 - Alfalfa-Seed Investigations In Utah, John W. Carlson

UAES Bulletins

For many years alfalfa-seed production problems have engaged the attention of investigators in various parts of the world. Those factors which are regarded as of greatest importance in seed-setting are general climate, current weather, air humidity, soil moisture, and insect relationships within the various alfalfa-seed districts. Some attention in research has been given to pollen fertility and ovule sterility, as well as to general flower dynamics in relation to environmental conditions. Efforts have been made to develop strains of alfalfa having pollen that is resistant to injury by moisture or having self-tripping flowers or autogamous strains of alfalfa whose flowers …

Bulletin No. 263 - Relative Produciton Of Feed Grain From Spring-Grown Cereals In Utah, R. W. Woodward, D. C. Tingey

UAES Bulletins

Nearly one-third of the cropped acreage of Utah is devoted to cereals. Except for wheat, most of these crops are fed locally. In addition to this, an average of over a million bushels of corn, barley, and oats is shipped into the state each year to be used in various livestock and poultry industries.

The purpose of this publication is to show the comparative amount of feed produced by the different crops--wheat, oats, barley, and corn--under similar conditions as determined for the specified four years by acre-yields obtained in various agricultural regions of the state. One should bear clearly in …

Bulletin No. 259 - Drainage Of Land Overlying An Artesian Groudwater Reservoir: Final Report, O. W. Israelsen, W. W. Mclaughlin

UAES Bulletins

This bulletin constitutes a final report of some phases of cooperative drainage studies in Cache Valley, Utah. The drainage problem in Cache Valley is typical, in many respects, of drainage problems in other irrigated valleys of Utah and the West in general. Application of the principles indicated by the problems will doubtless add materially to the productivity of the land in the several communities concerned and will also contribute to the advancement of public welfare in the general improvement of health, economic, and social conditions. Alkali and water-logging affecting large areas are causes not only of low productivity of the …

Bulletin No. 257 - Factors Promoting Positive Health In School Children, Almeda Perry Brown

UAES Bulletins

It is necessary only to observe groups of rural children to become convinced that too many of them are deprived of their rightful heritage of positive health.

Why children playing together, working together, under conditions which apparently vary but little, should exhibit such wide variation in health conditions, is a question of vital importance to all concerned with the care of children.

It was with the hope of finding some of the causes behind these variations that the present study was initiated. That the problem is complex and intricate was fully realized, and no hope was entertained that its solution …

A History Of Wool Manufacturing As It Is Related To Wool Marketing In Utah, George Elwood Spencer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has been advocated by many sheep raisers and individuals interested in the wool industry of Utah, that wool manufacturing should become a leading industry of this state. Factors which seemingly corroborate such contentions are readily apparent. Utah's annual wool clip ranges between eighteen and twenty-five million pounds of wool.(1)*. The state is located in the center of the Western range states where the bulk of the higher quality wool of this country is grown. A part of the marketing costs of freight, commission charges to a limited extent, and high storage costs could be decreased. These savings would result …

Color Reactions As An Aid To Seed Indentification, Carlton Leo Schmit

Bachelors’ Theses

Plants have long been classified according to their physical likenesses and structures. To sort plants according to such a basis, a botanist uses a key. In most cases, these keys are based on the flower or fruit of the plant. Sometimes there are disadvantages in using these structures, because usually they are only present for a short portion of the year. In a few cases, the seeds or fruits of plants have been used as a basis of classification as, for instance, in the Umbelliferae, Alismaceae, and Bidens.

The Weather Effect On The Characteristic Protein Values In Wheat, Mary Margaret Murphy

Bachelors’ Theses

Scientific investigation has proved conclusively that the protein content of the wheat kernel is the most important factor in determining the quality of the flour obtained. A high protein wheat is used for flour for bread making, and a low protein wheat for pastry flours. The quality of the protein must be determined by baking experimental loaves.

The year 1934 was a year of drought. In all parts of the country the wheat crops were affected by the lack of rainfall; hence, the protein value of the wheat must necessarily have been affected in some manner. The United States Department …
