Bulletin No. 381 - The Organization And Structure Of Egg Marketing In Utah, Roice H. Anderson Apr 1956

Bulletin No. 381 - The Organization And Structure Of Egg Marketing In Utah, Roice H. Anderson

UAES Bulletins

Sale of eggs is one of the major sources of farm income in Utah. In 1954 egg receipts represented 8 percent of the farm cash income. This was the lowest percentage since 1929; receipts reached a high of 13 percent in 1935.

The relative importance of egg production doubled from 1924 to 1929 when the proportion of cash farm income from eggs increased from 4 to 9 percent. Since 1929 it has fluctuated without apparent trend. The percentage of cash income from eggs was high in years when egg prices were high relative to the other agricultural products and low …

Bulletin No. 384 - Virus And Viruslike Diseases Of Stone Fruits In Utah: A Handbook For Their Identification And Control, B. L. Richards, L. C. Cochran Jan 1956

Bulletin No. 384 - Virus And Viruslike Diseases Of Stone Fruits In Utah: A Handbook For Their Identification And Control, B. L. Richards, L. C. Cochran

UAES Bulletins

Intensive research over the last 20 years has shown that many of the previously unexplained and seemingly mysterious disorders of stone fruit trees in Utah are infectious diseases caused by viruses. Others were shown to be the result of noninfectious genetic abnormalities or of adverse chemical and physical factors in the environment of the plant. The purpose of this handbook is to help orchardists and others recognize these diseases and disorders and understand better their etiology or cause. The handbook will also bring together basic information which will aid in their control.


Bulletin No. 379 - Biology And Control Of The Peach Twig Borer (Anarsia Lineatella Zeller) In Utah, Charles J. Sorenson, Farrell H. Gunnell Dec 1955

Bulletin No. 379 - Biology And Control Of The Peach Twig Borer (Anarsia Lineatella Zeller) In Utah, Charles J. Sorenson, Farrell H. Gunnell

UAES Bulletins

The peach twig borer, Anarsia lineatella Zeller, sometimes called the peach worm, annually damages peach, apricot, nectarine, prune, and plum orchards in Utah. Many buds and twig terminals are destroyed each spring by the overwintered generation of partially grown larvae. These emerge from their winter quarters almost as soon as host trees begin their spring growth. From the time the fruit becomes about half grown until it is harvested, later generations of twig-borer larvae feed on it causing irregular, gummy cavities which make it unfit for market.

In order to work out a control program for any insect, its life …


Bulletin No. 378 - Labor Structure And Labor Problems: Utah Sheep Ranches, 1952-1953, William A. Dehart, William H. Metzler Sep 1955

Bulletin No. 378 - Labor Structure And Labor Problems: Utah Sheep Ranches, 1952-1953, William A. Dehart, William H. Metzler

UAES Bulletins

This study deals with the problem sheep ranchers have in recruiting workers to meet their labor needs. Consideration is given to the composition of the work force on sheep ranches, to wages, the amount and causes of labor turnover, and to ways to reduce turnover. Labor recruitment practices are also discussed and evaluated in terms of available sources of farm labor, the possibilities of maintaining a stable supply, and the effect of farm labor problems on recent changes in the operations of sheep ranch enterprises. The primary focus of attention is on regular hired labor on Utah sheep ranches, although …


Bulletin No. 376 - Potato Production, Utah 1953: An Economic Analysis, E. M. Morrison, W. G. Kearl Jun 1955

Bulletin No. 376 - Potato Production, Utah 1953: An Economic Analysis, E. M. Morrison, W. G. Kearl

UAES Bulletins

The potato enterprise is important in providing a cash crop and a means of diversifying and intensifying the operations on many of Utah's irrigated farms. It is particularly important in those areas where, because of short growing season or inadequate markets, other intensive crops cannot be produced economically.

Potatoes have accounted for around 2.5 percent of the total cash farm income and around 10 percent of the cash farm income from crop sales over the past several years. The gross value of the crop has been between four and five million dollars in 8 of the last 12 years from …

Bulletin No. 374 - Fertilizer Reuirements Of Alfalfa Hay In Utah, R. F. Nielson, J. P. Thorne, G. T. Baird

UAES Bulletins

This bulletin is a report of one phase of research in agronomy. What is agronomy? Agronomy is the science of crop production and soil management and includes a scientific study of all phases of soils and soil conservation, irrigation practices, fertilizer usage, crop rotations, plant breeding, selection and management of new crop varieties, weed control, and other practices that lead to increased production of better quality crops.


Bulletin No. 373 - Biennial Report Of The Utah Agricultural Experiment Station, 1952-1954 Dec 1954

Bulletin No. 373 - Biennial Report Of The Utah Agricultural Experiment Station, 1952-1954

UAES Bulletins

Our way of life is based on the ability of our agriculture to produce abundantly, efficiently, and at a low cost; and the position of agriculture today is largely a result of the research efforts of the state agricultural experiment stations and the United States Department of Agriculture. In the 66 years since the establishment of the Utah Agricultural Experiment Station, its scientists have found solutions to many of the problems peculiar to its location, topography, and climate. It is logical to rely on these same research forces to solve the problems of the future.

During the past biennium a …


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 Aug 1954

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.

Bulletin No. 367 - Hybrid Corn Tests In Utah, Rollo W. Woodward, Rex F. Nielson Feb 1954

Bulletin No. 367 - Hybrid Corn Tests In Utah, Rollo W. Woodward, Rex F. Nielson

UAES Bulletins

The last summary of recommended corn hybrids published from this station was in 1939. Since that time there ha been a complete change of corn hybrid being tested and a considerable increase in both acreage and yield throughout the state. Corn used a silage is one of the most productive feed crop that can be grown on the irrigated land of the state. Under favorable moisture and fertility condition , hybrid corn can give outstanding yield of shelled corn per acre. At the present time only about one-sixth of the total corn acreage is devoted to grain, the bulk being …


Bulletin No. 365 - Costs, Quality, And Prices Of Fluid Milk In Rural And Urban Areas Of Utah And Montana, Wells M. Allred, Edward H. Ward Dec 1953

Bulletin No. 365 - Costs, Quality, And Prices Of Fluid Milk In Rural And Urban Areas Of Utah And Montana, Wells M. Allred, Edward H. Ward

UAES Bulletins

The major purpose of this study was to make an analysis of marketing fluid milk in sparsely populated areas of the West. Costs of processing and delivering milk in small and medium sized processing plants were ascertained. In addition prices and quality of milk available to consumers in sparsely populated and urban areas were compared.


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.


Bulletin No. 359 - Broiler Production In Utah: An Economic Analysis, Earnest M. Morrison, Thomas I. Gunn Feb 1953

Bulletin No. 359 - Broiler Production In Utah: An Economic Analysis, Earnest M. Morrison, Thomas I. Gunn

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 …

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.


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 …


Bulletin No. 353 - Effect Of Nitrogen Fertilizer On Yield And Protein Content Of Winter Wheat In Utah, Howard B. Peterson Jun 1952

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. 354 - Marketing Of Chickens From Producer To First Handler Washington, Oregon, And Utah (1948-1949), Roice H. Anderson Jun 1952

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 …


Bulletin No. 346 - Irrigation Waters Of Utah, J. P. Thorne, D. W. Thorne Jun 1951

Bulletin No. 346 - Irrigation Waters Of Utah, J. P. Thorne, D. W. Thorne

UAES Bulletins

Irrigation waters are never pure. All contain some dissolved salts. The amount may vary from a trace to concentrations so great that the water is unfit for use. The kind of salt in irrigation water may be even more important than the total amount. Borates in extremely low quantities, for example, may injure or kill crop plants. If the proportion of sodium in irrigation water is high, the soil may be gradually rendered unproductive. On the other hand, the salts may consist in part of essential plant nutrients or other helpful salts that aid in keeping soils productive.


Bulletin No. 349 - Management Of Irrigation And Drainage Enterprises In Utah: With Special Reference To The Northern Cache Valley Area, J. Howard Maughan, O. W. Israelsen Jun 1951

Bulletin No. 349 - Management Of Irrigation And Drainage Enterprises In Utah: With Special Reference To The Northern Cache Valley Area, J. Howard Maughan, O. W. Israelsen

UAES Bulletins

The purposes of this study on the management of irrigation and drainage enterprises in northern Cache Valley, Utah, are to assist farmers in the area and in other similar areas to learn the causes of their irrigation and drainage problems and to determine the best approach toward their solution. The bulletin first presents some of the general problems connected with irrigation and drainage organizations, and then discusses the problems of the local area, known as the Cub River area.


Bulletin No. 348 - Cost And Efficiency Of Producing Canning Corn In Cache County, Utah, 1949, Earnest M. Morrison, Willis G. Kearl Jun 1951

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.

Bulletin No. 347 - The Life History And Management Of The Mountain Whitefish Prosopium Williamsoni (Girard) In Logan River Utah, William F. Sigler

UAES Bulletins

In 1948 a comprehensive fishery investigation on Logan River was initiated by the Department of Wildlife Management, Utah State Agricultural College, and the Utah Cooperative Wildlife Research Unit. Three masters' theses have been completed on life histories and populations to date (Thoreson, 1949; Fleener, 1950; Pechacek, 1950). One phase of this investigation is a study of the mountain whitefish Prosopium williamsoni (Girard).


Bulletin No. 350 - Cemeteries Of Box Elder And Summit Counties, Joseph A. Geddes, Carmen Fredrickson Jan 1951

Bulletin No. 350 - Cemeteries Of Box Elder And Summit Counties, Joseph A. Geddes, Carmen Fredrickson

UAES Bulletins

One of man's greatest challenges is to build institutions that adequately meet basic needs. A cemetery is a social institution invented to take care of needs related to the dead.

Times and conditions change. A design which seemed adequate when initiated may soon become archaic and out-moded if it is not modified in the light of new discoveries.

This study raises many issues about cemeteries. As one reads the bulletin many questions concerning the nature and function of other institutions arise. What is their condition in contrast with the cemeteries?

This publication, the first in an institution series planned by …


Bulletin No. 340 - Adult Honey Bee Losses In Utah As Related To Arsenic Poisoning, G. F. Knowlton, A. P. Sturtevant, C. J. Sorenson Aug 1950

Bulletin No. 340 - Adult Honey Bee Losses In Utah As Related To Arsenic Poisoning, G. F. Knowlton, A. P. Sturtevant, C. J. Sorenson

UAES Bulletins

During 1947 the 55,000 colonies of honey bees in Utah produced approximately $545,000 worth of marketable honey and beeswax. In addition they pollinated most of the fruit, alfalfa seed, various vegetable and other seed crops. By 1949 the price of honey had declined to where the crop of honey and beeswax was worth $253,000, produced by 49,000 colonies of bees. The value of bees in Utah as pollinating agents to fruit and seed crops greatly exceeds the income received by beekeepers from bee products sold. Because agriculture receives such great benefit from bees, it seems reasonable that farmers who are …


Bulletin No. 338 - Nutrient Deficiencies In Utah Orchards, D. W. Thorne, F. B. Wann Apr 1950

Bulletin No. 338 - Nutrient Deficiencies In Utah Orchards, D. W. Thorne, F. B. Wann

UAES Bulletins

When farm products are sold, some of the essential part of the soil are also marketed. If this process is continued, the soil may be eventually impoverished to the point where it cannot support high crop yields. In addition to direct soil depletion, unbalanced soil management practices may produce soil conditions that prevent or limit the uptake of certain elements by plants even though there may be enough total supply of the elements present to last hundreds or even thousands of years.

Both processes have been going on in many Utah orchards. Sale of fruit has gradually depleted the soil. …


Bulletin No. 345 - Effectiveness Of Gravity Drains And Experimental Pumping For Drainage Delta Area, Utah, O. W. Israelsen, D. F. Peterson Jr., R. C. Reeve Feb 1950

2. To determine …


Bulletin No. 342 - The Nutritive Content Of The Grazing Sheep's Diet On Summer And Winter Ranges Of Utah, C. Wayne Cook, Lorin E. Harris Jan 1950

Bulletin No. 342 - The Nutritive Content Of The Grazing Sheep's Diet On Summer And Winter Ranges Of Utah, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Approximately two million sheep graze the native ranges of Utah each year. These animals are on the range most of the year and their food supply must come from range plants as they are normally selected. The nutritive value of range forage is often borderline or deficient in essential nutrients, yet, sufficiently adequate to prevent obvious physiological disorders. These mild deficiencies may affect the productive efficiency of the animal even though no symptoms are apparent.


Bulletin No. 333 - Drainage Districts In Utah: Their Activities And Needs, J. Howard Maughan, Orson W. Israelsen, Eldon G. Hanson Jan 1949

Bulletin No. 333 - Drainage Districts In Utah: Their Activities And Needs, J. Howard Maughan, Orson W. Israelsen, Eldon G. Hanson

UAES Bulletins

The need for drainage in Utah was widely recognized before 1900, resulting in passage of a drainage district law in 1896 and provision for cooperative drainage research beginning in 1904. The drainage district laws, developed and improved during the half-century ending 1948, have served as the major basis for drainage organization in the state.


Bulletin No. 336 - Utah Agricultural Experiment Station Biennial Report, 1946-1948, R. H. Walker Jan 1949

Bulletin No. 336 - Utah Agricultural Experiment Station Biennial Report, 1946-1948, R. H. Walker

UAES Bulletins

During the past biennium there has been a general expansion in the research program of the Agricultural Experiment Station. This was made possible through increased state legislative appropriation and through federal funds made available by the Agricultural Research and Marketing Act which passed Congress in August 1946, although funds were not available until August 1947. Grants-in-aid by state and private agencies have also made other research possible.
