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 …

Bulletin No. 278 - Should Flax Be Grown In Utah, R. W. Woodward, D. C. Tingey, A. C. Dillman

UAES Bulletins

Flax has been considered as a possible crop for growing under irrigation in Utah because of its high acre return in some of the northern States. One of the functions of a State experiment station is to test new crops and varieties. A series of experiments , therefore, has been conducted in Utah to determine the yields of flax as compared with small grains both under irrigation and on dry lands. This bulletin report s a summary of the results of these experiments together with a discussion of comparative returns from flax and small grains.

Two types of flax, seed …

Bulletin No. 277 - A Study Of Utah's Winter Range: Composition Of Forage Plants And Use Of Supplements, A. C. Esplin, J. E. Greaves, L. A. Stoddart

UAES Bulletins

Range forage provides the foundation for the maintenance ration available for most sheep wintered in Utah. The nature and amount of supplemental concentrate or roughage needed with this forage to provide an adequate and efficient ration for sheep naturally depends on the nature and amount of range forage available. Present uncertainty as to the relative merits of the various available supplements originates largely through a lack of definite knowledge as to the composition and feeding value of the various range plants that go to make up the range-forage supply on the particular range in question.

The Life History Of The Dewberry Fruit Worm Cacoecia Rosaceana (Harr.) In Utah, Merlin W. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study has been to determine the identity and the life history of certain larvae attacking dewberry fruits and foliage in a few sections of Utah. The dewberry fruit worm as it was called until it was definitely identified the oblique-banded leaf-roller, was first observed by farmers at Granite and Butlerville in 1932. Since 1934 it has been found affecting dewberries in other parts of northern Utah.

This investigation was begun in the spring of 1935 and continued until the fall of 1936, being made possible through the Utah Agricultural Experiment Station, Department of Entomology, and with …

The Microflora Of Milk Drawn Aseptically From The U.S.A.C. Dairy Herd, Lewis W. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early studies on the bacterial content of milk were made mainly to satisfy the interest of people who wished to determine the various materials that contained bacteris. Soon the value of bacterial counts, as an indication of the general conditions of production, of handling, and of the keeping qualities of milk, became evident and bacterial counts were used to obtain information concerning these problems. Numbers of bacteria in milk have been used also in the studies of the desirable and undesirable changes in milk.

In the last few years our citizenry has been made more conscious of the presence and …

An Economic Analysis Of Farm Tenure In The Uintah Basin, Utah, Glen B. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Before presenting an economic analysis of farm tenure in the Uintah Basin, it will be helpful to consider some aspects of the historical, economic, and social background of that portion of the region included in this study.

A portion of the Uintah Indian Reservation, which was created in 1861, was opened to white settlement under the homestead and townsite laws on August 28, 1905 after 103,000 acres of farming land had been allotted to individual Indians living on the reservation and 276,000 acres reserved for Indian grazing lands and timber reserve.

Because of the large deposits of asphalt products that …

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 Identification Of The Tomato Mosaic Virus Prevalent In Utah, Ross D. Watson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Collections of tomato mosaic virus obtained from Utah and California produce a localized severe leaf and stem necrosis on Datura meteloides. After the streaked plant has stood sufficiently long to permit secondary growth to occur, a systemic diseased expression develops in a few of the plants. No reference to a similar development on Datura meteloides following inoculation with the tobacco mosaic virus was found in the literature.
