The Utilization Of Grasses And Forbs In Relation To The Intensity Of Grazing In The Mixed Prairie Near Hays, Kansas, Noel Runyon

Master's Theses or Doctor of Nursing Practice

The principal occupation of the inhabitants in the Great Plains Region is livestock farming. The problems confronting the farmers and ranchers of this large area are many and varied. Not the least of these problems is the one of a proper stocking rate for the various types of ranges in order to secure a maximum production with the least in capital outlay and range deterioration. Another problem that has presented itself in recent years is the one of revegetating thousands of acres of marginal and semi-marginal land so that mother nature may again heal the marks of erosion and bring …

Nutritional Status Of Some Utah Population Groups, Almeda Perry Brown

Faculty Honor Lectures

The science of nutrition is the science of life. Though man is still ignorant of the true nature of that elusive force we call life, he has learned by means of the discovered laws of nutrition how to preserve and prolong life as well as how to add to the satisfactions of living.

The emergence of the sicence of nutrition from the maze of superstition which for centuries clouded man's thinking is a fascinating story. A story, however, that arouses a feeling of regret that for so long a time man was willing to attribute to supernatural forces all phenomena …

Two Newly Discovered Conifers, George F. Beck

All Faculty Scholarship for the College of the Sciences

Two genera of coniferous wood, apparently not listed among the Tertiary woods of the western states, have been recognized in the Percy Train collections from Rainbow Ridge, northwestern Nevada. These two, Tsuga (hemlock) and Chamaecyparis (cedar) bring up to 14 the genera of coniferous wood more or less certainly identified from the period and area in question.

Status Of Tertiary Woods Of The Western States Representing The Juglandaceae, George F. Beck

All Faculty Scholarship for the College of the Sciences

For many years there has been uncertainty concerning the generic status of some fossil leaves belonging without question to the walnut family as a whole. A review of the woods of Juglandaceae as they have appeared in Tertiary horizons of the western states has suggested which genera are present, and in what proportions their leaves (or other remains) might be expected to appear.

North American Prairie, J. E. Weaver

Papers of John E. Weaver (1884–1956)

From the highlands of central Mexico across the entire United States and northward into Canada extends the great mid-continental prairie. On the east it is in contact with the deciduous forest. From this central mass the prairie extends westward beyond the Rocky Mountains across Wyoming into eastern Utah, and southwestward through northern New Mexico in to northern Arizona. The Palouse Grasslands occurred in eastern Oregon and Washington, and other parts of the far Northwest. The Pacific Prairie was found in the Great Valley of California, and the-Desert Plains Grassland still occupies much of southern Arizona and New Mexico and southwestern …

A Suggestion As To The Cause Of Glaciation: The Reciprocal Reinforcement Theory, John D. Boon Sr.

Field and Laboratory

The temperature of the earth depends largely upon the energy received from the sun, and the promptness with which this energy is returned to space. In the long run the energy received by the earth must be equal to that given out. If the energy received is returned at once, it will have no effect upon the temperature of the earth. In this case the earth will be just as cold as it would be if the sun did not exist. This means, of course, that there must be a lag in the return of solar energy if it is …

Replacement Of True Prairie By Mixed Prairie In Eastern Nebraska And Kansas, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Destruction of a portion of one plant association and its replacement by another has just been completed. This has occurred not as the result of man's interference with the vegetation nor the effect of his grazing animals. It has been due to a dry climatic cycle and has been accomplished within a period of seven years. The scene of action was the broad area on the western edge of true prairie in central Kansas, eastern Nebraska, and eastern South Dakota. It is distinctly east of the mixed prairie in the central portion of these states. Although the phenomenon was general …

Bulletin No. 310 - The Influence Of Cropping On The Nitrogen, Phosphorus And Organic Matter Of The Soil Under Irrigation Farming, J. E. Greaves, C. T. Hirst

UAES Bulletins

Most soils contain sufficient nutrients for normal plant growth, with the exception of nitrogen, phosphorus and potassium. These elements are used by plants in the largest quantities and the amounts of these in the soil govern its productivity. Soil organic matter is of prime importance for it is the matrix which holds the nitrogen and modifies the structure, temperature, and water-holding capacity of the soil. The organic matter is the very life of the soil, for it is in and on it that bacteria work and by so doing determine the kind and speed of reactions which occur. It is …

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to present the data on nitrate contents and nitrate production in tests where straw or stalk residues were left on the surface through subsurface tillage, as compared with check treatments where these residues were plowed under or were absent. Nine of these tests were at Lincoln, Nebraska, and one was at the Hastings, Nebraska, Hydrological Project. Two tests were conducted in 1939, four in 1941, and four in 1942.

Some Physical And Chemical Properties Of Wheat Starch In Relationship To The Maturity Of The Wheat, Claude W. Bice

Master's Theses or Doctor of Nursing Practice

Wheat is one of the most valuable of economic plants and is grown extensively throughout the world. Because of the unique chemical and physical properties of its gluten, wheat is superior to all other cereals for bread making. Its high starch content provides a tremendous source of energy as a food, as well as filling certain industrial starch needs, especially in textile manufacturing . The present study on properties of immature and mature wheat starches should be of inestimable worth for evaluation of damaged wheats for starch production, as well as for yielding fundamental information which may facilitate the use …

Bulletin No. 309 - An Economic Analysis Of The Milking Enterprise On Farms In The Ogden Area, Utah, 1937-39, George T. Blanch, Dee A. Broadbent

UAES Bulletins

The area included in this study is part of the better irrigated section of Utah. Although the soils are variable, that part used for arable agriculture is generally fair to good. The poorer soils are used largely for pastures which makes necessary a forage-consuming livestock enterprise in the farm organization. Dairy cattle is the type of livestock most common. Topography, climate, irrigation water supply, transportation, and markets all permit or favor a relatively intensive and successful cash-crop and dairy type of farming. The average farm is relatively small in area of cultivated land which also makes necessary intensive usage, high …

Bulletin No. 308 - A Farm Management Study Of Farms With Dairy Enterprises In The Ogden Area, Utah, 1937-39, George T. Blanch, Dee A. Broadbent

UAES Bulletins

Farmers in the irrigated sections of Utah are confronted by several difficult problems in the management of their farms. The farms are far distant from the consumption centers of the country which results in high freight rates and a need to produce concentrated products for market, and also in violent fluctuations in farm prices. The farms usually consist of relatively few crop acres which makes intensive usage necessary for an adequate sized business. Most farms also include a considerable acreage of land unsuited to tillage. The utilization of this land makes necessary the inclusion in the farm business of a …

How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse

Aspen Bibliography

Additional low cost forage is urgently needed by Utah's range livestock industry. Seeding of depleted tracts in accordance with recently developed methods and principles will help supply this forage and is entirely feasible. Where the value of the increased forage will repay the cost of planting, careful reseeding of selected sites is fully justified.

The important part that reseeding can play in restoring ranges to their former capacity has been demonstrated. Although satisfactory results can be obtained on many sites during average or better years, much more study is needed to insure consistent success in abnormal years and to extend …

Studies Of The Excretory System Of The Passer Domesticus, James Julian Stout

Bachelors’ Theses

In past years and in recent years most animals have been made a subject of study. However, very little or no research has been made on the most common of all birds, the English Sparrow. This thesis will endeavor to take up the study of the excretory system of the Passer Domesticus. In most animals the excretory organs are the kidneys and the skin, which pass of nitrogenous and other waste matters from the body. I will take up the main organ of this system the kidney at this time, with a histological study of the ureter, and leave the …

Conception Rate In Dairy Cattle By Artificial Insemination At Various Stages Of Estrus, George W. Trimberger, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A breeding experiment with 295 dairy cows and heifers of the Jersey, Guernsey, Ayrshire, and Holstein breeds was conducted in the University of Nebraska dairy herd. The females were given artificial services at various stages of estrus to determine the effect of time of service upon conception. The results obtained indicate the potential benefits in higher percentage of conception in females bred during the middle of estrus, toward the end of estrus, and those bred in full heat and rebred in 24 hours. The latter is usually not very practical, especially in artificial breeding rings, but there are occasions when …
