A Study Of Semisterility And Its Lineage Relationships In Translocation Stocks Of Barley, Horace Marr Waddoups

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley (Hordrium sp.) is the most important spring sown cereal crop in Utah, both in acreage and in yield of total digestible nutrients per unit area. It also rates high as a feed crop in the United States. For this reason it is important that varieties are available which are high in yield, high in quality, and disease resistant, along with other desirable characteristics. In order to work toward this end most efficiently, it is first necessary that the genetics of the barley plant be worked out.

The Effect Of Time, Quantity, And Kind Of Irrigation On The Yield Of Sugar Beets, Delos Boyd Archibald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations on factors affecting yield of sugar beets during the past two years at Newton and Garland, Utah, have shown two outstanding facts about irrigating sugar beets. First, the amount of water applied may not be as important as the time at which they receive it. Second, sugar beets should not be made to suffer for water in the early part of their growing season.

These observations suggest the need for further studies on method, time and quantity of irrigation. Further information on the most economical use of irrigation water for sugar beets would be of great value to the …

The Effects Of Fertilizer And Moisture On The Yield Of Sweet Corn, Rex F. Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sweet corn is rapidly becoming an important cash crop in many of the irrigated regions of the intermountain West. The lacome from this crop is relatively small in comparison to that from other major agricultural products; however, sweet corn production has a definite place in the economy of the region.

One of the factors limiting increasing acreage of sweet corn in many areas is low yields. Yields have been increased naterially in recent years with the development of hybrid varieties, superior to the standard varieties previously used. Better cultural practices are improving yields, but much remains to be done in …

The Comparative Value Of Commercial Phosphoric Acid As A Fertilizer, Bruce L. Baird

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The practice of applying fertilizers to the soil by adding the liquid form to the irrigation water is increasing in popularity. There are several advantages maintained for such a method of application. Some of the advantages are:

(A) Ease of application.

(B) No special equipment is required for application.

(C) The fertilizer can be applied at any stage of plant growth without physical disturbance of the plant.

(D) Penetration into the root zone may be greater than the dry fertilizers.

Considerable phosphate fertilizer is used on soils of irrigated regions. If the behavior of liquid phosphoric acid after its incorporation …

The Diet And Daily Forage Consumption Of An Experimental Herd Of Sheep On Utah's Winter Range, Lee A. Sharp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The forage produced on Utah’s winter range is generally deficient in some nutrients that are required for the phase of sheep production that takes place on these ranges. This forage need only supply little more than maintenance ration, but because of low forage production on these areas and generally low quality forage, these requirements often are not met.

The Introduced Fishes, Game Birds, And Game And Fur-Bearing Mammals Of Utah, Boris Hewitt Popov

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For a number of years wildlife workers have realized the importance of the past histories of introduced species. Emphasis in recent years has been directed toward introductions because of the tremendous hunting and fishing pressures. Yearly increases in numbers of hunters and fishermen have been noted in Utah for the past forty years. It is hoped that this compilation of the histories of the introduced game and fish species of Utah will be of value to sportsmen and wildlife managers alike in planning future introductions.

The material included in this paper was obtained from United States Government reports, Utah Territorial …

Emergence And Survival Of Four Introduced Wheatgrasses As Influenced By Rate And Season Of Planting On Abandoned Farm Lands Of Utah, Donald N. Hyder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A great deal has been accomplished in developing methods of restoring abused lands through seeding, yet there is much to be desired in refinement of techniques and in substantiation of previous experimental results. Controversial opinions as to the best season of planting indicate that additional trials are needed. New species need to be introduced, developed, and proved. Methods are needed which lead to more efficient utilization of those factors limiting the degree of success in establishment. Since moisture is the most predominant limiting factor throughout the arid and semi-arid range land, special attention is given to more efficient utilization of …

An Evaluation Of Trout Stocking In The Logan River Drainage, Nels Andrew Thoreson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the more important forms of recreation in Utah is fishing. Each year since the end of World War II more than 100,000 resident and 4,000 non-resident fishermen have taken to the streams and lakes of this state. They spend approximately $2,200,000 each year in the quest of fish, mostly trout. In 1916, 25,473 licenses were sold, in 1937 the number of licenses had risen to 41,200, in 1945 the sales amounted to 104,000 and in 1947 had increased to nearly 131,000. Because of the increased number of fishermen each year, the desirability of greater numbers of legal-sized fish …

Inheritance Studies In Stem Rust Of Wheat, Sayed Bad Shah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat is an important food crop of the world, especially in Soviet Russia, U.S.A., China, India and Pakistan. Over one billion bushels of wheat are produced annually in U.S.A. The total area under wheat production in Pakistan during 1947-48 was 10 million acres with an average yield of 12 bushels per acre.

The stem rust disease has been known for along time to be destructive to grain crops, even centuries before the Christian era. Rust is of major importance in both the U.S. and Pakistan. Jethro Tull recorded rust in England in 1725. In 1916, rust was serious over the …

A Comparative Study Of Hydrogen Peroxide In Treating Milk For Cheddar Cheese Making, Mounir Ramzi Nagmoush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In many countries of the world and in some parts of the United States milk is produced which has a high bacterial contamination. Such milk of undesirable quality is frequently delivered to factories engaged in the manufacture of cheddar cheese. This milk commonly contains large numbers of lactic acid-producing bacteria or other types of microorganisms which cause objectionable flavors and textural defects in the cheese. The improvement of the quality of milk supply under some conditions is a matter of great difficulty so that the manufacture of inferior quality milk into cheese is a problem often encountered.

In the United …

Some Factors Associated With The Economic Feasibility Of Reseeding Privately-Owned Cattle Ranges In Utah, James R. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The forage depletion of western ranges which has occurred during the past century is partly the result of the belief by ranchers that the forage loss was temporary and not serious. Should more forage of a high quality be desired they thought it could be produced by reseeding the ranges. The native western forages, never abundant or luxurious by eastern concepts, nevertheless were of generally high qualities. Limited by low and erratically distributed precipitation, the sparse native forages have in many areas given way to low quality plants. These plants of low quality do not have to withstand the adverse …

Seed And Forage Production In Four Clonal Lines Of Alfalfa As Influenced By Lygus Infestation, John Keith Noyes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

No other forage crop cultivated in the United States can be used in as many ways as alfalfa. The variety of its uses make it a most useful forage crop.

The distribution of alfalfa is world wide and it plays a leading role in the production of livestock and their products. For general feeding of farm animals, alfalfa is unsurpassed. Used for pasture, it has a high capacity, which leads to large gains in grasing animals. If properly rotated and cared for, it adds nitrogen to the soil in a form that is available to plants and thereby increases crop …
