Bulletin No. 372 - The Nutritive Value Of Winter Range Plants In The Great Basin As Determined With Digestion Trials With Sheep, C. W. Cook, L. A. Stoddart, L. E. Harris

UAES Bulletins

During the winter grazing seasons from 1946 to 1953, studies were carried on throughout the desert ranges of western Utah to determine nutritive content and digestibility of range forage plants.

These desert areas receive about 7 inches of precipitation annually and the vegetation consists, chiefly, of saltbush and sagebrush types.

The average floral composition of the desert areas studied was about 74 percent browse, 25 percent grass, and 1 percent forbs. However, on some areas there was more grass than browse and, on still others, large quantities of forbs were present, primarily Russian-thistle.

Digestion trials were carried out under normal …

Bulletin No. 369 - Impact Of Urbanization In Davis County, Utah, Therel R. Black, Carmen D. Frederickson, William A. Dehart, C. Jay Skidmore, Don C. Carter

UAES Bulletins

This study of Davis County should assist community leaders to understand some areas of change and possible effects of changes in an urbanizing area and to understand possible sources of friction and cooperation. It should help residents of any urbanizing area to understand personal adjustments that may be necessary. Such understanding is needed by Utah's residents because Utah is becoming urban-in fact, approximately two-thirds of her population was urban in 1950. A brief summary of the study of Utah's fastest growing county shows the following changes during the 1940-1950 decade.

The Succession Of Vegetation On A Southern Utah Sand Dune, Elias S. Castle

Theses and Dissertations

The sand dunes lying ten miles northwest of Kanab in Kane County, Utah, support a sparse plant cover with four species dominating the vegetation: Psoralea stenostachys, Sophora stenophylla, Oryzopsis hymenoides, and Wyethia scabra var. attenuata. Of these Psoralea and Wyethia are endemic to the dunes or to a limited area which includes the dunes. The pineer species gain a start in the valleys between dunes and occupy the area only until sand covers them or until sand is blown away from their roots. Stabilization of the soils is not permanently in the interdune valleys and the dunes continue to wander. …

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 …

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 …

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 …

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 …

Weed Control Investigations On Some Important Aquatic Plants Which Impede Flow Of Western Irrigation Water, United States Department Of The Interior, Bureau Of Reclamation

Elusive Documents

During the past 50 years, the acreage of land placed under irrigation in the western United States has increased greatly to meet the growing demand for food and fiber production. To provide this water for crop production it is necessary not only for river waters to be impounded and irrigation canal distribution systems established but also for the irrigation waterways to be free of obstructing plant growths which impede the flow of water. This requires various types of weed control measures in order that originally designed carrying capacities of the waterways may be maintained. Methods involving new techniques developed mostly …

The Total Surface Of Some Soils As Related To Permeability And Water Retention Characteristics, Warren W. Rasmussen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally recognized that many of the chemical and physical properties of soils are dependent upon the surface activity of the finer soil fractions. The importance of the magnitude of the surface areas to such properties as base exchange, water-holding capacity, absorption of gases, and the plasticity of soils has been demonstrated. Attempts have been made to determine or estimate the surface of soils and soil fractions by various methods and to relate the values obtained to the physical and chemical characteristics exhibited by these materials. Most determinations have been based on calculations of surface area from mechanical analysis …

Distribution Of Fluorine In Utah County, Utah, Soils And Uptake Of Fluorine By Plants, E. Don Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluorine released from industrial operations is eventually deposited on the surface of the earth, intercepted by plants, or absorbed in open bodies of water. the term fluorine as used in this thesis will be considered to refer to fluorine in combined form.

Industrial expansion has caused atmosphere pollution from fluorine in many parts of the United States. Utah County, Utah, is one of the affected area, and is the principal area of concern in this thesis.

In the spring of 1951, Utah Agricultural Experiment Station initiated a broad investigation on soil, water, plant, and animal problems arising from fluorine atmospheric …

UAES Bulletins

The production of broilers in Utah has become increasingly important in the last few years. Data are not available prior to 1950 but in that year the gross income from the production of broilers was $629,000. In 1951 almost one and a half million broilers were produced bringing a gross income of $1,322,000 to Utah producers.

With the rapid growth in recent years has come a demand for information about this new industry from producers, prospective producers, processors of meat and feed, agricultural leaders, and agricultural advisers. As with most new industries little specific information has been available concerning the …

Commercial Fertilizers For Winter Wheat In Relation To The Properties Of Nebraska Soils, R. A. Olson, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this bulletin to report the investigations that have been made correlating soil properties and fertilization practices with yields of winter wheat. Since the success or failure of fertilization practices is so dependent on specific soil conditions, an attempt has been made here to further characterize the major soils of the different sections of the state which are devoted to wheat production and to analyze fertilizer practices and results in relation to the soil properties determined. The data are summarized for the four sections of the state designated as southeastern, east-south-central, west-south-central and western Nebraska. These …

Here are a few brief statements of some of the results of the work during the past two years.

Lawns - Their Establishment And Management, H G. Elliott

Journal of the Department of Agriculture, Western Australia, Series 3

It may be said that there is nothing more pleasing to the eye than a well kept lawn, be it in a home garden or covering a sporting area, and under Western Australian conditions there is no reason why a good lawn or turf cannot be developed and maintained-always provided that there is a sufficiency of water and proper care and attention are available.

Thinning Of Deciduous Fruits, F Melville, T F. Herlihy

Journal of the Department of Agriculture, Western Australia, Series 3

In the absence of any artificial control of the crop, most varieties of fruit trees will set much more fruit than it is possible for the trees to bring to marketable size and this is particularly the case with stone fruits. Even under good cultural and weather conditions the trees are often unable to bring the fruit to satisfactory size unless thinning is practised.

Bulletin No. 355 - An Economic Study Of The Production Of Canning Tomatoes In Utah, 1948 And 1949, Earnest M. Morrison, George T. Blanch

UAES Bulletins

Production of canning tomatoes is an important enterprise on many farms in Utah. In 1949 this crop brought about $1,772,000 and in 1951, nearly $2,750,000 to the farmers of the state (appendix table 1). Nearly all the canning tomatoes of the state are produced in the counties at the west of the Wasatch Mountains. In order of importance, these are: Davis, Weber, Utah, Box Elder, and Salt Lake (appendix table 2). Since tomatoes are processed relatively close to where they are grown, the income to farmers is not a complete measure of the importance of the tomato enterprise to this …

Poison Sedge And Cyanogenesis, R D. Royce

Journal of the Department of Agriculture, Western Australia, Series 3

During the afternoon of April 14 of this year, a flock of 800 sheep on a property in the Carnamah district was turned into an old stubble paddock which had been spelled for two months, after having carried the same sheep for the previous paddock, death having apparently occurred suddenly and without any struggling.

The rapidity and severity of the losses, together with the lack of observed symptoms, suggested that the trouble had been due to a cyanogenetic plant (a plant capable of killing stock by the liberation of prussic acid after ingestion.)

Bulletin No. 353 - Effect Of Nitrogen Fertilizer On Yield And Protein Content Of Winter Wheat In Utah, Howard B. Peterson

UAES Bulletins

Winter what is one of the major crops of Utah. For more than 50 years winter wheat has been grown on the dry lands of the state. It is about the only crop grown on these lands under the usual alternate cropping and fallow system. Since 1941 acreage in the state has increased about 60 percent. Little or no manure is applied and only occasionally is a legume green manure turned under. It is apparent that with the original low supply of nitrogen in most of the soils of the state, together with the depleting effects of the common cropping …

Bulletin No. 348 - Cost And Efficiency Of Producing Canning Corn In Cache County, Utah, 1949, Earnest M. Morrison, Willis G. Kearl

UAES Bulletins

The canning corn enterprise is becoming increasingly important to the farmers of Utah. For two decades prior to 1940, the acreage used in canning corn production varied between 400 and 800 acres; however, it has increased from 600 acres in 1942 to 6,300 acres in 1949. This increase has been larger, both in percentage and in absolute amount, than for any other intertilled or orchard crop in the state during the same period of time. In 1949 the farm value of canning corn sold was $567,000. Peas and tomatoes were the only canning crops which exceeded it in value.
