Bulletin No. 249 - Farm Versus Village Living In Utah, Joseph A. Geddes

UAES Bulletins

This is the first of a series of bulletins based on a study of Utah village life begun in 1927. The purpose of the investigation was to determine, under prevailing conditions, whether for farm people farm living is less desirable than village living. Four type villages were selected in as many counties for field studies.

Bulletin No. 247 - Effect Of Manure And Of Phosphorus Fertilizer On The Yield And Composition Of Alfalfa Hay, D. W. Pittman

UAES Bulletins

It has frequently been observed by practical stockmen that alfalfa hay produced on poor unproductive land has a much lower feeding value than hay produced on good productive land. Some have also observed that by the use of a supplemental feed rich in phosphorus (such as steamed bone-meal), the feeding value of this poor quality alfalfa hay may be improved, indicating that phosphorus deficiency is at least one cause of its low feeding value.

Bulletin No. 246 - Food Habits Of Rural School Children In Relation To Their Physical Well-Being, Almeda Perry Brown

UAES Bulletins

A study of school children's diet and of their physical status was made in six rural Utah communities, similar in size, and in social, economic, and physical characteristics.

Filicales Of The Mammoth Cave Region, William Youmans

Masters Theses & Specialist Projects

The purpose of this investigation was to determine the distribution of each species of ferns with regard to the geologic strata, altitude and temperature and moisture relationships. A systematic classification was made of all species of ferns found in the region.

The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker

Masters Theses & Specialist Projects

This study was undertaken for the purpose of determining the relation existing between the native forest cover and the chemical and physical properties of the soils of the Mammoth Cave National Park area. The study was suggested by certain references in the literature to a correlation existing between forest cover and the geological, chemical and physical nature of soils of this area. The recent attempt at reforestation in the Mammoth Cave National Park area renders such a study timely, and it is believed that the results reported in this paper will materially aid the Mammoth Cave National Park Commission and …

Bulletin No. 242 - Drainage Of Land Overlying An Artesian Ground-Water Reservoir: Progress Report, O. W. Israelsen, W. W. Mclaughlin

UAES Bulletins

Certain tracts of land in the West formerly used to produce grain and forage crops now produce only pasture grasses of comparatively low quality because of the water-logging and alkali accumulation which has occurred since irrigation was begun. Other tracts now producing only light crops of wild hay probably would produce profitable crops of alfalfa and clover, provided the water-table were lowered and the water-logged and alkaline condition of the soil removed. Still other areas are almost wholly nonproductive because of the concentration of excessive quantities of harmful alkali salts.

Knowledge concerning (1) the causes of water-logging, (2) economical methods …

Root System Of Quercus Macrocarpa In Relation To The Invasion Of Prairie, J. E. Weaver, Joseph Cramer

Department of Agronomy and Horticulture: Faculty Publications

Invasion of trees into grassland is primarily a phenomenon of plant competition. It involves the relation of the invaded and the invader to light and other atmospheric factors of the habitat, both physical and biotic. But perhaps even to a greater degree the edaphic factors, and especially water in dry climates, are concerned. Consequently to understand the reasons for plant distribution and the changes resulting from natural successions, a knowledge of the parts of the plants underground and of the interrelations of the root systems is of fundamental importance.

The great tension zone or ecotone between the deciduous forest formation …

Bulletin No. 236 - The Manufacture Of Cheese From Soft-Curd And Hard-Curd Milks, R. L. Hill, A. C. Merrill

UAES Bulletins

Little investigational work has been conducted on the effect of the hardness of curd of milk on the quality, quantity, and commercial value of cheese.

In July 1930, a preliminary report from the Utah Agricultural Experiment Station was made on these researches. This report indicated that for the manufacture of cheese hard-curd milk was far superior to soft-curd milk. This research is a continuation of that project.

Hard- and soft-curd milk used in the tests reported was obtained from Holstein cows. The fat content of each milk was practically the same. While the difference in curd hardness between the soft- …

Circular No. 99 - Utah Snow Sampler And Scales For Measuring Water Content Of Snow, George D. Clyde

UAES Circulars

Snow survey are usually conducted in uninhabited and mountainous areas, The surveyor must travel on snowshoes or skiis; therefore the necessary equipment must be light, strong, and compact.

Bulletin No. 234 - The Beet Leafhopper In Northern Utah, George F. Knowlton

UAES Bulletins

The first Utah sugar factory was erected at Lehi in 1891. Since that time many other factories have been built, and the growing of sugar-beets has become an important part of the agricultural program in many irrigated sections of this state. From almost the beginning, the tiny beet leafhopper, Eutettix tenellus (Baker), has threatened the very existence of this industry, and, in connection with the curly-top disease which it disseminates, has been responsible for the loss of many millions of dollars to the sugar-beet growers and sugar manufacturers of Utah. Poor prices, competition of other crops, sugar-beet nematode and crop …

Bulletin No. 233 - Observations On The Use Of Commercial Fertilizers On The Arid Soils Of Utah, D. W. Pittman, Clarence Burnham

UAES Bulletins

Only within the last few years has the question of commercial fertilizers been worthy of serious consideration in Utah. It has been considered that commercial fertilizers were unnecessary in Utah (1) because arid soils retain their virgin fertility much longer than soils in the humid region which are subject to continual leaching by heavy precipitation, (2) because livestock have always predominated in Utah's agriculture due to the vast areas adapted only to range purposes and livestock means manure to maintain fertility, and (3) because alfalfa, our principal feed crop, is also one of the best plants for gathering nitrogen from …

The Composition Of Soil Colloids In Relation To Soil Classification, Horace Byers, M. S. Anderson

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

For a period of approximately fifteen years investigators in the Bureau of Chemistry and Soils have been engaged in the accumulation of scientific data concerned with colloid material of the soil. During this period a large volume of accurate information has been secured which has been published in the form of bulletins and journal articles. So far as the Bureau publications are concerned, but little has appeared concerning theoretical aspects of the composition of the colloid. They have concerned themselves, for the most part, with methods of isolation and estimation, and determination of general physical and chemical characteristics.

The Effect Of Maturity And The Ethylene Chlorhydrin Seed Treatment On The Dormancy Of Triumph Potatoes, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Western Nebraska dry-land Triumph potatoes (Solanum tuberosum L.) vary in maturity at the time of harvest, from some that are very immature to others with vines which are entirely ripe. Variations in maturity may be due to such factors as early frost, drouth, destruction of vines by hail or early blight, time of planting, and strain type (whether early or late maturing). The question of seed maturity and its influence upon duration of the dormant period is of considerable commercial importance, since these potatoes are annually being planted in south Texas as early as December 26 and in southern …

The Alkaloids, Felix F. Barre

Electronic Theses and Dissertations

This thesis, presented for the degree of Bachelor of Science, provides a systematic chemical study of the alkaloids, a class of complex nitrogenous plant substances possessing basic properties. Barre opens by defining the alkaloids and surveying the various systems used to classify them, whether by natural versus artificial origin, chemical nucleus (pyridine, quinoline, or isoquinoline), volatility, or botanical family of origin, and outlines their general physical and chemical properties, including solubility, optical activity, and characteristic reactions with precipitating and color-test reagents.

The thesis details standard laboratory methods for the extraction and separation of alkaloids from plant material, including a step-by-step …

Bulletin No. 227 - Soft-Curd Milk, R. L. Hill

UAES Bulletins

Data on the early studies on the curd character of milk are found in Utah Agricultural Experiment Station Bulletin 207 and, therefore, are not included here. The key to research in this field came to light with the development of the "Hill Test," the results of which were first published in 1923. This test furnished a means of quantitatively measuring the difference in curd character of various milks.

The term "soft-curd" milk originated with R. L. Hill to describe milk which on coagulation with pepsin or rennin forms a curd that is soft and clabbery in consistency, differing widely from …

Inheritance In A Wheat Cross Of Ridit X Utac, C. Leland Dalley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Present-day plant breeding, on the foundation made many years ago, has achieved important scientific and economic results. By means of introductions and selections, superior strains such as Turkey and Kanred have been obtained. Through hybridization new combinations of characters result, combining desirable characters of different plant types in a single individual. In this program, wheat hybridization has occupied a worthy place.

Each year a number of wheat crosses are made at the Utah Experiment Station, the main purpose of which is to develop superior strains of wheat. Such an economic program is aided and hastened by studies in genetic behavior. …

Inheritance Of Glume And Kernel Color, Of Awnedness, And Of Spike Density In A Cross Between Ridit And Sevier Wheat, Leslie W. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper is devoted principally to the presentation and discussion of the results obtained when certain contrasting characters were brought together in a wheat cross between Ridit and Sevier 59. this is one of the crosses made in an attempt to develop a wheat adapted to this region with the following desirable qualities: Bunt resistance, strong straw, hard kernels, and heavy yield. How near this ideal is approached in succeeding generations can be told only by extensive tests. The genetic study herein presented was made to hasten the time when some of the progeny of this cross may become of …

Bulletin No. 224 - Muck Soil Investigations: Progress Report, Sanpete County Experimental Farm 1927-30, Inclusive, Le Moyne Wilson, George Stewart

UAES Bulletins

The estimated area of muck or peat soil in Utah is approximately 21,000 acres. The muck occurs in many valleys of Utah. The largest areas are in the Sanpete and Utah Lake Valleys. The area in the former is estimated at 6500 acres and the Utah Valley area at 9000 acres; the other areas, all more or less significant in size, are scattered throughout the state.

Investigations reported have been confined entirely to the Sanpete area which is located near the south and bottom end of the valley and is west of the towns of Chester, Ephraim, and Manti. During …

Circular No. 93 - Better Sugar-Beet Culture For Utah, George Stewart, D. W. Pittman

UAES Circulars

Utah was one of the first states to begin sugar-beet growing. The industry grew rapidly, favored by the climate, by the naturally productive soils, by the freedom from pests, and by the system of intensive irrigation agriculture. California and Utah were among the leading beet-producing states at the time of the World War, and under the stimulus of high prices they remained so until the great depression of 1920. After that, the frequent occurrence of curly-top and the rapid spread of nematode, together with the low price resulting from increased cane sugar production in the tropics and from other causes …

Infection Experiments With Spindle Tuber And Unmottled Curly Dwarf Of The Potato, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is probable that more than one insect species are capable of spreading some of the potato virus diseases. This conclusion was also indicated by repeated observations in the dry-land section of western Nebraska. While aphids are abundant and are probably the chief vectors of potato virus diseases in the more humid sections of the country, they are usually scarce in the western upland plains area and are not present in large enough numbers to account for the rapid spread of spindle tuber and unmottled curly dwarf which sometimes occurs. It was therefore considered advisable to determine the common potato …

Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick

UAES Bulletins

For a number of years many tons of sprayed or dusted hay have been fed successfully to livestock by stockmen interested in controlling the alfalfa weevil; nevertheless. the supposed cases of poisoning that have been reported naturally have caused concern among feeders.

Further confusion on this question has resulted from reports on studies designed to determine the effect of lead arsenate instead of calcium arsenate.

Whether the lead in lead arsenate has been a more injurious agent than the arsenic, of course, is difficult to state. Most of the experiments performed in the feeding of sprayed or dusted hay have …

Bulletin No. 222 - A Quarter Century Of Dry-Farm Experiments At Nephi, Utah, A. F. Bracken, George Stewart

UAES Bulletins

Utah is naturally an arid state with precipitation varying from 3.71 inches at Wendover, located in the vast desert region on the western border, to more than 40 inches on some of the mountain ranges. Desert and mountain areas and other untillable land combined total about 95 per cent of Utah's land area. The remaining 5 per cent constitutes all the land which will yield to cultivation either by irrigation or by dry-farming.

Durinog the 76 years that dry-farming has been practiced in Utah, many change in tillage practices, cropping systems, crops, and crop varieties have taken place in keeping …

Circular No. 90 - Swine Production In Utah, Harry H. Smith

UAES Circulars

During the last 20 years there has been a marked change in the type of hogs from the short-legged, wide-bodied or "hot-blood" type to a longer, somewhat more narrow-bodied, "leggier" type. For development of size in hogs they must have (1) length and depth of body, (2) length of leg, and (3) large but not coarse bones. The long-bodied rather "leggy" pig grows rapidly and makes the larger hog. While the modern hog is still a lard hog, it is not as thick and broad as were its predecessors. It is logical to assume that the hog of the future …

Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack

UAES Bulletins

For 17 years the late Dr. Herbert J. Pack, former Station Entomologist, made a study of the reptiles and amphibians of Utah. His original idea was to publish a comprehensive treatment of the snakes and lizards of his state, and whenever opportunity was afforded collected data on their distribution, habits, and economic importance. At the time of his death, on January 5, 1930, many notes and drawings of lizards were left; a manuscript on snakes, presented for his master's thesis to the Utah State Agricultural College in 1923, was also in his possession. Bulletin 221 contains essentially the information presented …

Underground Plant Development In Its Relation To Grazing, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Grasslands or grazing lands are relatively dry lands. Drought, at least in the surface soil, is always imminent. The necessity for the seedling to make immediate and extensive contact with deeper, moister soil is apparent. The water relation is usually controlling, and the success or failure of the seedling largely depends upon its ability to develop an absorbing system adequate in extent and activity to furnish the necessary supply.
