Farm Business Management Data And Practices In South Dakota: 1956 Annual Report, Charles H. Benrud, Roland Brunsma

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

This project, "Farm Business Management Data and Practices", was set up to begin in 1955, with farmers and ranchers in the seven "types-of-farming areas" in South Dakota keeping records on receipts, expenses, inventories, and other items and having their books analyzed by the Agricultural Experiment Station Economics Department at the end of the year. Only a few participated the first year, but in 1956 a total of 57 cooperators turned in record books for analysis. The purpose of this project if to obtain data on costs, returns, and organization on farms and ranches of various types in the different types-of-farming …

Chlorophyll And Productivity In A Mountain River, William J. Mcconnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigation of primary production in streams and rivers has lagged behind similar investigations in marine and lacustrine environments. Recently, however, Odum (1956) has demonstrated methods that allow the estimation of productivity of most moving waters. For reasons discussed later in this paper, Odum's method is not satisfactory for shallow, very rapid rivers as typified by Logan River. The present investigation then was primarily an exploration of a method possibly applicable to measurement of productivity in shallow rapid rivers.

Investigations of phases of the ecology and distribution of the main contributors to primary production, the benthic algae, was a necessary corollary …

The Effect Of Variety, Harvest Time, And Brine Separation On Thiamine, Riboflavin, And Niacin Contents Of Green Lima Beans, Prasertsri Dee-Ananta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increasing importance of the lima beans as a substantial cash crop for the growers or farmers and as a quality food for the consumer has initiated many investigations directed towards improving its quality as a vegetable crop. Lima beans are well suited for processing; hence, studies of the quality of different varieties in relation to time of harvest have been made. Host processors are in agreement that the beans attain maximum quality before they are fully mature. After that, the yield and size increase whereas the quality decreases.

The Effect Of 2 Soil Fertility Levels On 5 Potato Varieties In Relation To Yield, Specific Gravity And Chipping Quality, Gayland D. Robison

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The potato enterprise is important in Utah as it provides a cash crop and also a means of diversifying and intensifying the operations on many irrigated farms. It is of particular value in the sections of the state that have a short growing season where other crops cannot feasibly be produced. The potato chip industry supplies a demand for large quantities of potatoes. The usage by this industry makes it a major factor in potato farming economy.

The making of chips originated over a hundred years ago as the result of an accident. A silver of potato fell into a …

Pollution of the atmosphere and its potential deleterious effects on health, industry, agriculture and natural resources are causing grave concern in many parts of the world. In the past century there has developed in the fields embraced by physical and biological sciences a considerable knowledge of theoretical and applied information, serving as a versatile tool in combating such problems. Air pollution problems seem to have gained much attention with the rapid development of various industries in major parts of the world. Rural and urban areas adjoining these industrial locales are confronted with the dangerous overall problems of air pollution. Evidently, …

Artificial Respiration During The Apnea Of Cerebral Trauma, Thorvald W. Christiansen

Loma Linda University Electronic Theses, Dissertations & Projects

Cerebral concussion often results in profound respiratory depression. The earlier workers in the field of experimental concussion concluded that artificial respiration could be a life preserving procedure in 4 many instances. More recently, however, it has been held that this form of resuscitation is of little or no value.

Because of this conflict in viewpoint and inasmuch as the latter interpretation was made as a result of studies that were not primarily directed towards assessing the worth of artificial respiration during the apnea of experimentally induced concussion, this study was planned with the hope of resolving the differences of opinion. …

The Relationship Between The Systemic Action Of Various Carbohydrates And The Development Of Subsequent Dental Caries, Pat O. O'Day

Loma Linda University Electronic Theses, Dissertations & Projects

Previous work with rats, hamsters and monkeys has shown a direct relationship between refined diets high in carbohydrates and caries susceptibility. Adequate amounts of vitamins and minerals have been shown to be necessary for proper tooth development and resistance to decay. The glycoprotein content of hamster teeth raised on a non-cariogenic Purina ration was reported to be lower than the amount found in the teeth of animals raised on a high sugar cariogenic diet.

In order to determine the caries susceptibility produced in Albino rats by different common carbohydrates, an artificial feeding technique was utilized in which the amount and …

Learning Through Judging For 4-H Home Economics Club Members, Marie Curry, Ima Crisman

SDSU Extension Circulars

Judging is an every-day activity. A person judges every time a choice is made whether it is food, clothing, home furnishings, or entertainment. In 4-H club work, judging is simply a matter of selecting one article or product over another because of certain qualities. In order that club girls may learn to choose wisely, they need practice in making comparisons and recognizing excellent qualities.

The Natural Reproduction Of The Cutthroat Trout, Salmo Clarki Richardson, In Strawberry Reservoir, Utah, William S. Platts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Strawberry Reservoir, Utah is an 8,000 acre lake at the elevation of 7,550 feet; it has a maximum depth of 52 feet and an average depth of 18 feet. The supply of cutthroat trout eggs used to replenish and distribute this trout throughout the state are taken from two spawning traps located on reservoir tributaries. Because it has not proven economical to raise cutthroat to a larger size than newly hatched fry, it is at this stage they are planted. Because of competition, predation, and lack of space the planting back of fry to maintain the fishery and spawning run …

Some Chemical Properties Of The Profiles Of Two Soil Series As Shown By Horizons And By Increments, Verle Q. Hale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil classification in this country is based on the system proposed by Marbut in 1920 (2). This system uses eight criteria, one of which is the chemical composition of the soil horizons. Workers in the field of soil survey are depending more and more upon laboratory data to characterize and differentiate soils not only at the series level but also at higher levels of classification where it may be necessary to establish the presence or absence of critical horizons or characteristics. This was predicted by Robinson (16) when he said that laboratory analysis is needed to give "precise physical meaning …

An Ecological Study Of The Bottom Fauna Of Bear Lake Idaho And Utah, Earl W. Smart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In evaluating the potential ability of a lake to produce fish, probably no single standard is so important as an estimate of the amount of bottom fauna (Deevey and Bishop, 1942).

The study of the bottom fauna of Bear Lake was a part of the investigation of its limnology and fisheries, begun in 1952. This study was sponsored through federal monies made available through the Dingle-Johnson Act. The primary purpose of the study was to examine all the evidence in estimating the fish producing capacity of the lake. Bear Lake is the second largest fresh water lake in Utah but …

An Evaluation Of The Salt Tolerance Of Particular Varieties, Strains, And Selections Of Three Grasses And Two Legumes, Farrel John Olsen Jr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In arid and semiarid areas in the Western United States, soluble salts tend to accumulate in the soil in amounts harmful to crop production. A considerable portion of this land cannot be reclaimed due to the poor quality of permeability of the soil. Therefore, the wise selection of crops that will produce satisfactory yields on these soils in necessary.

The salt tolerance of many crop plants has been investigated; however, more information is needed on the relative salt tolerance of varieties, strains, and selections. Such information will permit the selection and development of varieties and strains of crop plants which …

Linkage Relationships Of Located And Unlocated Genetic Testers In Certain Normal And Translocation Stocks Of Barley, William Ralph Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley is an economically important cereal crop throughout most of the world. The study and elucidation of the genetic complex of this plant will add to its extensive usefulness to man, and will also provide valuable information for similar research projects on other crop plants.

The Effect Of Soil Moisture And Fertilizers On Seed Germination, Stephen Dubetz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Failure of viable seeds to germinate results in poor stands and often in lower yields. Some of the more important factors that affect germination of seed are temperature, moisture, aeration, and alkalinity.

Planting of speciality crops under irrigation in southern Alberta, Canada, usually is done when temperature is favourable to germination. However, soil moisture, especially in the seed zone, may not always be adequate - a situation brought about, in part, by the strong winds that prevail in this area. Results at the Experimental Farm, Lethbridge, Alberta, show that irrigated crops respond to phosphorus and nitrogen. During the past six …

Cost Of Marketing Utah Lambs At Alternative Markets, Norman E. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of lamb marketings

The production and marketing of lambs is important in Utah's economy. In 1956, Utah ranked fifth in the United States in lambs produced and saved, with 1,038,000 head produced and 840,000 marketed for consumption, table 1. Cash receipts from the lamb marketings during the year amounted to over 10 million dollars, and in addition, the state's economy benefited through revenues, employment, and raw materials which were provided by the lamb industry.

Marketing decisions

Lamb producers and handlers are faced with many decisions in marketing their lambs. They not only must decide when and where to sell, …

Linkage And Inheritance Studies In Barley (Hordeum), Robert E. Heiner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley has had wide acceptance not only as a cultivated crop but also as an excellent source of genetic material. Barley was being used in inheritance studies by Tschermak when he rediscovered Mendel's laws of heredity. Since then barley has become one of the most widely used plants for genetic studies known today.

More than 100 characters have been investigated indicating the relative ease of classification. There are 7 linkage groups corresponding to the 7 chromosomes in which 2 or more characters have been located as reported by Robertson (1939). But Kramer, Veyl, and Hanson (1954), from translocation experiments, suggest …
