Bulletin No. 368 - Drainage Of The Cache Valley Lowlands, Willard Gardner, Orson W. Israelsen May 1954

Bulletin No. 368 - Drainage Of The Cache Valley Lowlands, Willard Gardner, Orson W. Israelsen

UAES Bulletins

Now, slightly more than a hundred years since irrigation was first started in the West, many of the low-lying valley lands produce only poor quality pasture grasses because of waterlogging, salinity, and alkali. Other lands now produce only light crops of wild hay, and still other land areas are almost wholly non-productive because of the concentration of excessive quantities of harmful salts. This waterlogging is largely a result of irrigation on the higher lands, although rain and snow waters aggravate the situation. The water not used by the highland crops seeps into the lower areas, bringing harmful salts to the …

Feeding The Dairy Herd For Profit, R. A. Cave, D. F. Breazeale, Chase Wilson, Ervin Kurtz, Emery Bartle May 1954

Feeding The Dairy Herd For Profit, R. A. Cave, D. F. Breazeale, Chase Wilson, Ervin Kurtz, Emery Bartle

SDSU Extension Circulars

Dairy cows, in order to make milk in large quantities, must be supplied with liberal amounts of the raw material from which milk can be made. That means good feed. The average production of South Dakota milk cows for the year 1952 was 4170 pounds of milk and 156 pounds of butterfat. Much of this relativ~ly low production is due to poor feed and lack of enough feed. Production and feed records shown in Table IV - page 25 reveal that one way to get increased production is to give the cows more feed. Feed is the greatest single item …

Age And Growth Of The Utah Chub, Gila Atraria (Girard), In Panguitch Lake And Navajo Lake, Utah, From Scales And Opercular Bones, John M. Neuhold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous literature indicates the opercular bone as a useful tool for the determination of age and growth of fish. The reliability and validity of this method is tested for two populations of Utah chub. Age and growth are calculated for 222 Utah chub collected from Panguitch Lake and 212 Utah chub collected from Navajo Lake, southern Utah, in 1952-1953 from both scales and opercular bones. Scales are measured with the aid of a projector. Opercular bones are measured directly. The center of growth of the opercular bone is posterior to the posterior lip of the fulcrum. Correction for curvature is …


Use Of Corn Syrup Solids Of Different Dextrose Equivalents In The Manufacture Of Frozen Desserts, Wiggo F. Axelgard May 1954

Use Of Corn Syrup Solids Of Different Dextrose Equivalents In The Manufacture Of Frozen Desserts, Wiggo F. Axelgard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ice cream industry continually faces the problem of improving its frozen desserts. At the present time corn syrup solids are being used to supplement milk serum solids to improve the body and texture of these products.

One of the problems is to increase the total solids content of frozen desserts without increasing sweetness or developing sandiness in the finished product. There is a limit to the amount of milk serum solids that can be used because of the danger of sandiness and the cost. The use of corn syrup solids helps to overcome these limiting factors.

The corn syrup …


The Adaptation Of The Neutron Scattering Technique Of Soil Moisture Determination To Field Application, Robert L. Uhler May 1954

The Adaptation Of The Neutron Scattering Technique Of Soil Moisture Determination To Field Application, Robert L. Uhler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

At the present time there is a recognized need for a better means of measuring soil moisture in situ. Soil moisture measurements are required in fundamental studies of soil moisture flow and soil-plant-water relationships as well as in practical studies in irrigation practices. Various phases of engineering also utilize soil moisture data, for example, soil moisture determinations are made during the construction of earth dams, road cuts and fills, and under airfield runways. The desired method should be quick, reliable, and adaptable over the moisture range from oven dryness to saturation.

Research in nuclear physics has revealed the neutron …

Inheritance Studies Of A Wheat Cross To Six Races Of Covered Smut, Douglas R. Dewey May 1954

Inheritance Studies Of A Wheat Cross To Six Races Of Covered Smut, Douglas R. Dewey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Covered smut is a fungus disease that has caused serious losses of wheat for centuries. Its origin is not known, but it was well known to early Romans as evidenced by the fact that they had a god, Robigus, whose special work was to watch over crops to "avert the mildew" (45). It is often referred to as "bunt" or "stinking smut of wheat". Throughout this paper the term "bunt" will be used to designate this disease in order to avoid confusing it with other smuts of wheat.

Bunt is worldwide in its distribution, but it is especially prevalent in …


The Effect Of Stage Of Maturity On The Quality Of Lima Beans For Processing, Abdul Razzaq Abdul Rahman May 1954

The Effect Of Stage Of Maturity On The Quality Of Lima Beans For Processing, Abdul Razzaq Abdul Rahman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lima bean* is one of the important vegetable crops in most of the countries where it is grown, including the United States of America. This crop is harvested for its green beans, which can also be processed, or allowed to mature as "dry beans."

The practice of growing lima beans for processing has indicated that quality and yield are influenced by many factors, among which the stage of maturity at time of harvest is possibly the most important.

Lima beans continue to increase in size until fully matured, but most processors agree th.at the green beans attain maximum quality prior …

Seasonal Yield And Nitrogen Content Of Three Grasses Grown Alone And In Association With Each Other And With White Dutch Clover, Donald B. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The chief aim of pasture research is to discover means of providing the largest possible amount of highly nutritious forage at the time the animal requires it. Throughout the grazing season animal herbage requirements are relatively constant, while herbage production from pastures usually is quite variable.


Application Of Paper Electrochromatography To Isolation Of Tobacco Mosaic Virus, Bertram E. Bordewick May 1954

Application Of Paper Electrochromatography To Isolation Of Tobacco Mosaic Virus, Bertram E. Bordewick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of the problem

The complete study of a virus disease often reaches a stalemate because of failure to isolate the virus itself in a purified form. Methods in current use, such as ultracentrifugation, precipitation, fractionation, and spectroscopic analysis, have in some cases proved successful in virus purification work. Frequently these techniques have not proved satisfactory, particularly with phloem-type viruses which are not mechanically transmitted. This investigation was undertaken to determine the possibility of isolating these and other viruses by electrochromatography.


The Chromatographic Purification Of Human Red Blood Cell Acetylcholinesterase, Richard P. Dunkley May 1954

The Chromatographic Purification Of Human Red Blood Cell Acetylcholinesterase, Richard P. Dunkley

Theses and Dissertations

A process of column chromatography of human erythrocyte acetylcholinesterase, using a cationic exchange resin, was investigated as a possible method for the primary partial purification of the enzyme on a large scale. The investigation was based, first; on a detailed study of the enzymatic stability to variation in hydrogen-ion and salt concentrations for periods of time extending to forty eight hours and, second; on an investigation of the degree of adsorption by the resin of the enzyme at various pH values within the pH range of enzyme stability. A method for the analysis of the enzyme activity of large numbers …


Control Of Dodder In Alfalfa Seed Crops, William Orvid Lee May 1954

Control Of Dodder In Alfalfa Seed Crops, William Orvid Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dodder (Cuscuta spp.) is a parasitic weed which attacks alfalfa, clovers, lespedeza, and many other species of plants. This pest is especially troublesome when these crops are grown to produce seed.

Control of dodder should increase the financial income of a seed producer in several ways. First, control should make it possible for a producer to raise seed of high quality which will command a better price; second, it should enable the producer to increase yields; and last, it should eliminate much of the cost of harvesting and cleaning his product.

Where dodder is present in seed, the grower …


Factors That Contribute To Success Of Selected Farm Ownership Borrowers In Utah, Grey M. Jensen May 1954

Factors That Contribute To Success Of Selected Farm Ownership Borrowers In Utah, Grey M. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Farming is a complex business. Financial success in farming is influenced by the organization and operation of the farm unit. The principal problem confronting farmers is knowing how to manage the resources to attain maximum income over a period of time. Combinations of resources involve problems relative to crops, livestock, machinery, labor, capital, credit, and many others. An attempt has been made in this study to measure the results of different combinations and operation of resources and to determine their association with financial success of the farm.

Factors Affecting Length Of Tenure Of Vocational Agriculture Teachers Who Are Recent Graduates Of Utah State Agricultural College, John M. Oglesby

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since its beginning well over a quarter of a century ago, the Vocational Agriculture program has become an integral part of the American school system. The legislative groundwork for Vocational Agriculture, as well as all other vocational programs, was set in 1917 with the passing of the Smith-Hughes Act. Further related legislation was passed in 1929 and 1934, but the program received its greatest federal boost with the passing of the George-Deen Act in 1936 and the George-Barden Act in 1946, both of which provided for the annual expenditure of federal funds in support of vocational education. The George-Barden Law, …

Muskrat And Waterfowl Production And Harvest On Dingle Swamp, Bear Lake County, Idaho, Henry M. Reeves

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dingle Swamp, a high altitude marsh, is located in the extreme southeastern corner of Idaho in Bear Lake Valley. The 16,000 acre marsh, one of the largest in the state, is separated from Bear Lake by only a narrow curved sandbar. Numerous islands, ponds, and channels diversify the characteristic bulrush vegetation of the marsh. The largest body of water, Mud Lake, is approximately 1 square mile in area. Several thousand muskrats and fair numbers of waterfowl, particularly Canada geese, are produced annually on the marsh.

Marketing Aspects Of Cattle Finishing Operations Major Cattle Finishing Areas Of Utah, 1951-52, Robert L. Fulton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

On January 1, 1952, 50,000 head of cattle were on feed for slaughter in the state of Utah (6). This was an increase over previous years. The average number of cattle on feed for slaughter January 1st during the 1948-52 period was 45,000 head. This number was 30 percent larger than the average number on feed during the 1943-47 period. As shown in figure 1, the number of cattle on feed has fluctuated from year to year. The years with the least number of cattle on feed were those in the early thirties during the depression and drought. Since 1936 …


The Effect Of Limited Moisture Supply At Various Stages Of Growth On The Development And Production Of Hybrid Corn, Ralph E. Campbell May 1954

The Effect Of Limited Moisture Supply At Various Stages Of Growth On The Development And Production Of Hybrid Corn, Ralph E. Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Corn occupies from 25 to 30 percent of the crop land harvested in the United States. In recent years the acreage devoted to corn in this country has been decidedly greater than that devoted to any other cultivated crop. In 1944 its dollar value exceeded the combined values of wheat, barley, rye, grain sorghums, and cotton.

Although South Dakota lies on the northwestern fringe of the corn belt, the corn crop is one of the most important in that state. Corn production in that area is somewhat unstable because of drought. Corn often fails to reach full maturity before the …


A Study Of Mineral Nutrition Of Range Cattle In Southeastern Utah, Robert J. Raleigh May 1954

A Study Of Mineral Nutrition Of Range Cattle In Southeastern Utah, Robert J. Raleigh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cattlemen of south central Utah in Sevier and Wayne County areas have been plagued for the past twenty-five or thirty years by a malady known to the cattleman as "Brisket Disease." It is a chronic disease affecting both male and female of all ages. It is characterized in advance stages by enlargement of the brisket and throat regions, loss of appetite, a general unthrifty condition and marked ascites. The seriousness of the disease is indicated by a morbidity rate varying from one to five percent of the cattle grazing these areas with almost one hundred percent mortality rate.

Many of …
