The Emergence And Survival Of Certain Forage Plants When Seeded In A Saline Soil, Devere Richard Mcallister

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salty soils are recognized as an ever increasing problem connected with irrigation agriculture. Millions have been spent by state, federal and private agencies on technical research in an attempt to solve this problem. Other millions have been spent on drainage projects, land leveling, field explorations and soil amendments attempting to alleviate the situation in the field.

A Curriculum Study Of The Biological Science Courses In The Secondary Schools And College Of Utah During 1947-48, Merrill H. Gunnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

At the present time there is a feeling among biologists in Utah that there should be improvement in biological science courses and course sequence to better fill the needs of the non technical student. There are many students filling group requirements with an accumulation of courses which may not provide them with the more important fundamental concepts and principles in biology. Information concerning these courses in high schools and colleges in necessary to provide a basis for curriculum revision in the field. Such information should be useful in evaluating the present system and suggesting modifications. Because of the need for …

The Effect Of Ddt Residue On The Composition And Digestibility Of Alfalfa Hay, Than Myint

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

DDT (2,2 bis (p-chlorophenyl) 1,1,1-trichloroethane) was first synthesized in 1874 by Seidler in Switzerland, however, its effectiveness as an insecticide was not known until about 1942. The active principle was first known as G.H.B. (Gesarol-Neccid Base): but in 1943 DDT was suggested as an abbreviation for Dichlore Diphenyl Trichloroethane (Kaaegie, 1946). In fact DDT, as a powerful insecticide is one of the developments made during World War II. The importance of DDT in the control of the common insect enemies of mankind, such as mosquitoes, flies, moths, and many agricultural insect pests is realized more day by day. Many studies …

Bulletin No. 330 - Peach Orchard Soil Mangement Studies, A. L. Stark, D. W. Thorne

UAES Bulletins

Peaches are the most important fruit crop in Utah. The total number of peach trees is greater and the volume of fruit produced for market is larger than of any other fruit. Most of the peaches are produced by a large number of growers who have small plantings. These small orchards contribute substantially to the total income of the growers and it is, therefore, important that maximum yields of high quality fruit be obtained from limited acreage.

A survey of the fruit production problems in Utah reported in 1938 (13) indicated that poor soil management practices were important in contributing …

Cherry County (Nebraska) Extension: Historical Documents

Educational program of extension work was supported entirely from County Tax funds. The Budget for the coming year was raised to $3,475 from last years budget of $2975. This was very much appreciated, as it will allow a more complete extension service program. This is $25.00 under the $3500 calling allowed by the new bill L. B. 405

The annual meeting was attended by 164 people. The program which was held in the new 4-H building and at the experimental Station, consisted of a business session, four talks on current livestock problems, and a morning and afternoon session of witnessing …

The Apparent Digestibility Of Prairie Hay Harvested At Three Stages Of Maturity, Arnold Bernard Nelson

Electronic Theses and Dissertations

More land in the United States is used for grazing and hay production than for all other farm crops grown. Well-managed pastures and rangeland have always been recognized as an economical source of feed and recently have commanded much attention as an effective means of conserving soil resources and preventing erosion. In the states if North and South Dakota, Nebraska, Colorado, Wyoming and Montana, about 67 per cent of the total land in farms and ranches is in pasture and hay. Over 60 per cent of the entire area of South Dakota and about 83 per cent of the area …

Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The marked improvement in the apparent nutritive value of soybean protein after heating has long been recognized. The fundamental cause of this improvement has never been fully understood. Furthermore, commercial soybean oil meal varies considerably in nutritive value although heat treatment is common in most processing plants. Since heating is generally regarded as deleterious to the nutritive quality of protein, the following investigations of various treatments of soybean oil meal are of particular importance in developing a soybean or soybean oil meal of maximum and uniform nutritive value.

Effects On Different Intensities Of Utilization Upon The Underground Parts Of Short Grasses In West Central Kansas, Farrel Branson

Master's Theses or Doctor of Nursing Practice

Work on root systems of forage plants has indicated that a knowledge of root relationships is fully as important in determining the actual conditions of ranges or pastures as is knowledge of the effects of grazing upon aboveground portions of plants. This is especially true in arid or semiarid regions since plants of these areas are frequently subjected to long periods of drought, high temperatures, and high wind velocities. Some xeric plants have a thickened cuticular layer, stomates that open only at night, and other mechanisms that prevent loss of water that is absorbed by the roots. However, in plants …

The Future Of Utah's Agriculture, W. Preston Thomas

Faculty Honor Lectures

Since the settlement of the state Utah's agriculture has been based primarily on irrigated farming. The major part of farm income and the livelihood of farmers and farm families comes from this type of farming. Also, Utah's hopes for agricultural expansion and development, the adding of new wealth, and the providing of employment for Utah rural people, lie in a further development of irrigation and irrigated farming. Range livestock and dry farming, when measured by income and employment of labor have been, and are likely to remain, minor enterprises when compared to irrigated farming. In this discussion of Utah's agriculture …

The Vitamin A And Carotene Content Of Nebraska Butter, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The vitamin-A, carotene, fat and moisture concentrations of Nebraska creamery butter were determined at monthly intervals for 25 months. Samples were obtained from 14 creameries located throughout the state. Their vitamin-A and carotene determinations were made with the aid of a spectrophotometer, and their fat and moisture analyses were determined by the A.O.A.C. methods. From a comparison of these data with the results of investigations in other states it was concluded that Nebraska butter was at least equal in vitamin-A value to average United States butter.

Bulletin No. 327 - Utah Agricultural Experiment Station Biennial Report, 1944-1946, R. H. Walker

UAES Bulletins

During the past biennium there has been a general expansion in the research program of the Utah Agricultural Experiment Station. Although some of the investigations were curtailed by lack of personnel and equipment and the pressure of wartime assignments, many of the staff were able to devote more time to research because of a lessening of the teaching load at the College. The emergency caused a re-examination of the research program, old projects, no longer urgent were weeded out, others were revised to meet the needs of the changing times, and many new projects were initiated to extend the research …

Bake Bread Successfully, Anna M. Wilson

SDSU Extension Circulars

During the latter spring and summer months of 1946 the United States was able to send more wheat abroad to starving people because we use 80 percent extraction flour instead of the customary 72 percent. Using 80 percent extraction flour taught us that degree of refinement does make a difference in the way flour must be handled in making yeast bread. In this circular we shall learn why wheat means so much to a world harassed with famine and how we can make better use of wheat by understanding the principals involved in breadmaking.

Pig Typhus (Salmonellosis Suis), L. Van Es

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Salmonellosis suis or pig typhus, also designated as pig typhoid, infectious necrotic enteritis, or "necro," is an infectious disease among young pigs. It constitutes a major factor in the mortality of juvenile swine, and as such must be regarded as a more or less perennial hazard in swine production. Infectious necrotic enteritis caused by Salmonella suipestifer is the subject of the present publication.

Bulletin No. 324 - Some Physical And Chemical Responses Of Agropyron Spicatum To Herbage Removal At Various Seasons, L. A. Stoddart

UAES Bulletins

Management of arid western ranges must be based upon the physiology of the individual plants which constitute the range. Too little is known of the ability of range plants to continue normal functioning under stress of grazing. Grazing doubtless has some beneficial influences in arid climates because it reduces transpiring surface. Possibly "pruning" has some stimulating effect, especially upon shrubs, and also, grazing animals plant seeds through trampling action. Despite these possible benefits, both trampling and removal of herbage by grazing must be .regarded as fundamentally detrimental to the welfare of plants, especially in arid climates. Trampling, especially on wet …

The Utilization Of Food Elements By Growing Chicks. Xi. A Comparison Of Ground Wheat And Ground Rye In Rations For Growing Chicks, C. W. Ackerson, W. E. Ham, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The effect of replacing the shorts and bran of a standard ration by ground wheat or ground rye was studied with two lots of newly hatched chicks. 2. Comparisons were made on the basis of equal intakes of dry matter and nitrogen by all chicks. 3. The wheat-fed lot made a significantly greater gain than the rye-fed lot. 4. Several cases of curled-toe paralysis occurred in the two lots, and a tendency to cannibalism appeared in the rye-fed lot.

Mirid-Bug Injury As A Factor In Declining Alfalfa-Seed Yields, Charles J. Sorenson

Faculty Honor Lectures

During the forty or more millions of years that insects have inhabited the earth they have developed remarkable adaptations and great powers of reproduction that have enabled them to spread over most of the world and occupy all of its habitable environments. In cultivating the land and in growing crops, man has disturbed the balance in nature which formerly prevailed. By doing this he has unwittingly assisted many insect species to multiply in unprecedented numbers by providing them with more delectable food in abundance and by transporting them from place to place and from continent to continent in his migrations …
