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 Sep 1954

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. 370 - The Superb Plant Bug, Adelphocoris Superbus (Uhler): Its Life History And Its Relation To Seed Development In Alfalfa, Charles J. Sorenson, Lowell Cutler Aug 1954

Bulletin No. 370 - The Superb Plant Bug, Adelphocoris Superbus (Uhler): Its Life History And Its Relation To Seed Development In Alfalfa, Charles J. Sorenson, Lowell Cutler

UAES Bulletins

Infestations of the superb plant bug, Adelphocoris superbus (Uhler), in Utah alfalfa fields first came to the attention of entomologists of the Utah Agricultural Experiment Station during their investigations of the seed chalcid and lygus bug problems of alfalfa seed production in the Uinta Basin from 1926 to 1934. Because of its occurrence in considerable numbers, particularly in first crop alfalfa fields with thin stands, the superb plant bug was suspected of interfering with seed development. Consequently an investigation of the activities of this insect was begun in the summer of 1932 and continued through that of 1933.

The Succession Of Vegetation On A Southern Utah Sand Dune, Elias S. Castle Aug 1954

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. …

Nebraska Agricultural Experiment Station: Historical Circulars

The Nebraska Agricultural Experiment Station has been working with partridge pea since 1944. Seed has been distributed for tests, and several farmers are now growing it. It is primarily a plant for soil conservation and soil improvement. Its value in comparison with other legumes have not been fully established.


50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams Jun 1954

50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams

Nebraska Agricultural Experiment Station: Historical Circulars

The North Platte Experiment was established fifty years ago. So many changes have occurred since then that few people remember why research in dry land agriculture was started in Nebraska and other Great Plains states. In order to get a proper perspective, it may be well to consider some early history.


Seasonal Yield And Nitrogen Content Of Three Grasses Grown Alone And In Association With Each Other And With White Dutch Clover, Donald B. Wilson May 1954

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.


Weed Control Investigations On Some Important Aquatic Plants Which Impede Flow Of Western Irrigation Water, United States Department Of The Interior, Bureau Of Reclamation Mar 1954

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 …

Bulletin No. 364 - The Halogeton Problem In Utah, C. Wayne Cook, L. A. Stoddart Nov 1953

Bulletin No. 364 - The Halogeton Problem In Utah, C. Wayne Cook, L. A. Stoddart

UAES Bulletins

Halogeton (Halogeton glomeratus) although introduced into Utah only 20 years ago, has spread widely on the west desert and into extensive areas on the east desert. This plant has become the most feared poisonous plant in the state because people have been lead to believe that it would limit livestock production to areas kept free of the weed.


Quantitative Study Of Degeneration Of Mixed Prairie, Farrell Branson, J. E. Weaver Jun 1953

Quantitative Study Of Degeneration Of Mixed Prairie, Farrell Branson, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

The vegetation of great areas of Mixed Prairie has been destroyed by plowing. But even larger ones, still intact, have degenerated far from a climax condition. The almost universal cause for such deterioration, aside from drought, is grazing. The objective of this study has been to ascertain the changes in vegetation that have resulted from 60-70 years of different intensities of grazing by cattle and to express them quantitatively. Since the early work of SAMPSON (7) it has been generally recognized that the forage value and carrying capacity are highest where the vegetation represents a stage close to the herbaceous …


The Preperation Of Rose Beds, C C. Hillary May 1953

The Preperation Of Rose Beds, C C. Hillary

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

Roses equal to the world's best can be produced almost anywhere in the south-western part of Western Australia with little more attention than is bestowed on most other flowers. It is essential, however, that suitable soil conditions should be provided for the plants.


Distribution Of Fluorine In Utah County, Utah, Soils And Uptake Of Fluorine By Plants, E. Don Hansen May 1953

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 …


Poison Plants Of Western Australia: The Thorn Apples (Datura Species), C A. Gardner, H W. Bennetts Mar 1953

Poison Plants Of Western Australia: The Thorn Apples (Datura Species), C A. Gardner, H W. Bennetts

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

Many garden enthusiasts are familiar with a shrub or small tree known as the "Angel's Trumpet" or "Trumpet-flowered Brugmansia." Some nurserymen call it "Brugsmania." There is another garden favourite which does not appear to possess a common name but is an annual or perennial plant from one to four feet in height, of summer growth and carrying erect violet or white trumpet-shaped flowers succeeded by large bristly or prickly pods. Both these are species of Datura. Another species is native to Western Australia while four more are introduced noxious weeds.

Bulletin No. 357 - Biennial Report, 1950-1952, R. H. Walker, D. A. Broadbent

UAES Bulletins

For sixty-four years the Utah Agricultural Experiment Station has been studying the problems of the farmer to make life on the farm more profitable and more enjoyable and in turn to improve the economy of the entire state. From the laboratories and from the experimental farms have come research results that have and will continue to mean dollars and cents to the farmer and increased prosperity to the state. Here are a few brief statements of some of the results of the work during the past two years.


Daffodils For Everyone, C C. Hillary Nov 1952

Daffodils For Everyone, C C. Hillary

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

For hundreds of years, poets and authors of renown in almost every country have extolled in verse and prose the loveliness of the daffodil. And well they might, since it is a floral gem of great beauty and one so widely grown that it might well be called everybody's flower.


Growth Regulating Substances Used For Weed Killing, G R. W Meadly Nov 1952

Growth Regulating Substances Used For Weed Killing, G R. W Meadly

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

Many discoveries of considerable importance to agriculture have been made accidentally while scientists have been working on other problems. The presence of a hormone, or growth-regulating substance, in plants has been known for many years, and in 1934 chemists were able to define the composition of this substance. With this information it was possible to prepare synthetically many related chemicals which were applied experimentally to plants, mainly for the purpose of stimulating growth, particularly with a view to promoting root development of cuttings.


Poison Plants Of Western Australia - Cape Tulip, C A. Gardner Nov 1952

Poison Plants Of Western Australia - Cape Tulip, C A. Gardner

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

For countless ages the flora of Western Australia remained as a separate entity undisturbed by plant intruders, but following upon the arrival of the white man came a number of plants, some of which proved able colonists. These included useful plants such as the naturalised clovers; others such as the Cape weed developed here to an extent not to be observed in their natural home. Some of the plants now regarded as troublesome weeds were accidentally introduced by various agencies, while others were deliberately imported, but have since become widespread.


The Wedge-Leaved Rattlepod, C A. Gardner Sep 1952

The Wedge-Leaved Rattlepod, C A. Gardner

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

During the last two years, work has been in progress near Fitzroy Crossing (West Kimberley) upon an investigation to determine the cause of Kimber- Iey Horse Disease, commonly known as "Walkabout Disease." The investigations are still in progress, and the findings when completed, will be published elsewhere, but the discovery that Crotalaria retusa L. is a cause—and probably the major cause —of this disease is of considerable importance. Because of this it is considered advisable to assist pastoralists to recognise the plant and by providing information on its habit, occurrence and distribution, to enable them to take steps to minimise …


Effects Of Excessive Natural Mulch On Development, Yield, And Structure Of Native Grassland, J. E. Weaver, N. W. Rowland Sep 1952

Effects Of Excessive Natural Mulch On Development, Yield, And Structure Of Native Grassland, J. E. Weaver, N. W. Rowland

Department of Agronomy and Horticulture: Faculty Publications

Prairie vegetation is so universally mowed, grazed, or burned that little information has been recorded on its behavior under complete protection. Climax grassland, when grazed lightly or even moderately, may retain essentially its natural composition over extremely long periods (16, 18). But aside from observation there is little information upon the unusual and rare phenomenon of complete protection of grassland from disturbance over a considerable period of time.


Bulletin No. 355 - An Economic Study Of The Production Of Canning Tomatoes In Utah, 1948 And 1949, Earnest M. Morrison, George T. Blanch Aug 1952

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 …


A Preliminary Study Of The Vegetation In An Exclosure In The Chaparral Of The Wasatch Mountains, Utah, Verl Phillips Allman Jul 1952

A Preliminary Study Of The Vegetation In An Exclosure In The Chaparral Of The Wasatch Mountains, Utah, Verl Phillips Allman

Theses and Dissertations

The purpose of this study was to determine the ecological factors existing within the chaparral community. The present status of the vegetation in a one-acre exclosure was analyzed and recorded so that subsequent improvement or eterioration might be noted. A brief history of the area, the weather, and the geology are presented. Many other aspects of the problems enumerated in the introduction need to be studied. This study provides a foundation for a more detailed study of the vegetation which may be undertaken at a future date.


Poison Sedge And Cyanogenesis, R D. Royce Jul 1952

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.)


Poison Plants Of Western Australia: Toxic Plants Of The Genera Gastrolobium And Oxylobium, C A. Gardner, H W. Bennetts Jul 1952

Poison Plants Of Western Australia: Toxic Plants Of The Genera Gastrolobium And Oxylobium, C A. Gardner, H W. Bennetts

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

Since the early days of settlement in Western Australia very heavy stock losses have resulted from the many poisonous species of the two closely related genera, Gastrolobium and Oxylobium which, with two exceptions, are widely distributed throughout the southern areas of the State. They constitute the largest groups of native poisonous plants and have been responsible for a large proportion of the economic losses due to plant poisoning.

Bulletin No. 354 - Marketing Of Chickens From Producer To First Handler Washington, Oregon, And Utah (1948-1949), Roice H. Anderson

UAES Bulletins

In 1949 the receipts from eggs and chickens amounted to 8.6, 6.0, and 13.2 percent of the total cash receipts from farm marketings in Washington, Oregon, and Utah, respectively. About three fourths of these receipts were from sale of eggs and one fourth from the sale of chickens. Receipts from chicken sales, while less important than from eggs, amounted to about 21.5 million dollars in 1949 in the three states. As would be expected, considering the importance of egg production in the three states, many of the chickens sold are cull layers and other chickens produced incidental to the egg …
