UAES Circulars

Circular No. 78 contains a summary of publications issued by the Utah Agricultural Experiment Station, through its Division of Publications, for the fiscal year beginning July 1, 1928.

Bulletin No. 212 - Studies On The Morphology Of The Beet Leafhopper, G. F. Knowlton

UAES Bulletins

The beet leafhopper, Eutettix tenellus (Baker), is one of the most serious insect pests of western North America. Its chief importance is as a vector of the plant disease curly-top, which it transmits to beets, tomatoes, beans, melons, and many other agricultural plants. The virus apparently is introduced into the plant during the process of feeding, and is responsible for the frequent and often enormous losses to the sugar-beet growers and sugar manufacturers of the west. Apparently, the virus multiplies and remains active in the body of a leafhopper for some time, making it possible for the insect, after once …

Bulletin No. 213 - Food Habits Of Utah Farm Families, Almeda Perry Brown

UAES Bulletins

This report is merely an attempt to set forth the findings of the investigation without making claim to their being conclusive except for the families included in the study. While the study was carried into a relatively large portion of the state, the records are too few in number for any claim to be made that they represent community food conditions. It is believed, however, that the records which form the basis of this report are representative of the food situation in the homes from which they come.

Bulletin No. 211 - Silage Corn Varieties For Utah, George Stewart, A. L. Wilson

UAES Bulletins

Utah is rapidly developing an important dairy industry. In addition to homegrown hay and grain, there must be some form of succulence. Pasturage is the common way of furnishing fresh feed in summer. In certain regions, silage and beet pulp are the winter forms. With a scarcity of beet pulp, silage corn is likely to be an important crop in the Great Salt Lake and Utah Lake Valleys, where corn does well. The data presented in this publication are related to the choice of a corn variety for ensilage.

Circular No. 77 - Measurement Of Irrigation Water, George D. Clyde

UAES Circulars

Water is the limiting factor in Utah's agricultural development. In spite of its admitted value the farmer knows less about the measurement of water than about any of the other commodities which he handles. He knows how to measure his land, his crops and his cattle, but he has little conception of how to measure his most valuable asset, viz., irrigation water. The importance of water measurement is not appreciated until the water-supply becomes over-appropriated and users begin interfering with each other's rights. Expensive litigation, which always follow controversies over water, is gradually convincing the farmer that water should be …

Bulletin No. 210 - The Mineral Content Of Grains, J. E. Greaves, C. T. Hirst

UAES Bulletins

It is generally recognized that shrunken, frosted, or smutty grain is inferior to sound, clean, plump grain. Much has been done on the protein content of grain, and the best millers today purchase grain for its protein content. Few give any consideration to its minerals. Yet do two bushels of sound, plump, clean grain of known protein content grown under the same or different conditions, have the same mineral content? If not, it is of importance to both the producer and consumer: to the consumer because it governs the nutritive value of the product; to the producer because it represents …

Bulletin No. 209 - Biennial Report Of Director: July 1, 1926-June 30, 1928

UAES Bulletins

No abstract provided.

Circular No. 76 - The Utah Agricultural Experiment Station, P. V. Cardon

UAES Circulars

The Utah Agricultural Experiment Station is one ,of three major divisions of the Agricultural College of Utah, these divisions being: (1) The College proper, (2) the Agricultural Experiment Station, and (3) the Agricultural Extension Service.

Circular No. 75 - Selecting Dairy Cows: Appearance Less Important Than Performance, George Q. Bateman

UAES Circulars

This is a cost study of three aged grade cows--E-10, E-11, and E-13--handled under identical conditions on the Dairy Experimental Farm. The three cows have been treated exactly the same since they came into the herd, all of the feed being weighed to each cow and the feed ref used weighed back. Each milking has been weighed and sampled daily; butterfat tests have been made every ten days.

Circular No. 74 - Rules And Regulations For The Fifth Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

This contest is conducted on a part of the Utah Agricultural College Farm near the experimental poultry yards. It is managed by the Poultry Department with an experienced poultry raiser in direct charge of the feeding and care of the hens in the contest. The buildings, grounds, and fences were built and furnished by the Experiment Station.

Circular No. 73 - Annual Summary Of Publications

UAES Circulars

Circular No. 73 contains a summary of publications issued by the Utah Agricultural Experiment Station, through its Division of Publications, since July 1, 1927. The publications of this Station are no longer sent to a general mailing list (except in cases of libraries, state editors, county agricultural agents, state vocational agricultural teachers, and state agricultural inspectors), but are sent only on request. Therefore, copies of any of the publications listed will be sent without charge to those requesting them as long as the supply is available. However, in the case of reprints (abstracts of scientific and technical papers) the …

Bulletin No. 207 - The Physical Cure Character Of Milk And Its Relationship To The Digestability And Food Value Of Milk For Infants, R. L. Hill

UAES Bulletins

In the feeding of infants,' cows' milk is the best and most common substitute for human milk. In the feeding of delicate infants, however, considerable difficulty is often experienced from its use. The ideal substitute for mothers' milk has not been found, and most of the clinical effort has been directed towards the modification of cows' milk for infants.

Comparatively little research has been done on the difference in the digestibility and food value of milks from different cows for the infant. It is a well-known fact that the curd of cows' milk forms in a tough mass which varies …

Bulletin No. 206 - Treehopper Injury In Utah Orchards, Charles J. Sorenson

UAES Bulletins

Treehopper injury is a problem that has given many fruit growers in Utah some concern during recent years. These people have observed that their young fruit trees and the twigs and smaller branches of older trees have been attacked during the autumn of each year in a manner that produced numerous cuts which later formed scars. The trees frequently became unthrifty, and more or less deformed and stunted, as a result of these annual attacks.

The investigation reported in this publication was made for the purpose of ascertaining the present status of the treehopper situation in Utah orchards.

Bulletin No. 205 - The Beet Leafhopper In Utah: A Study Of Its Distribution And The Occurrence Of Curly-Top, George F. Knowlton

UAES Bulletins

The sugar-beet industry of Utah, and many other western states, has suffered enormous losses from curly-top. Under natural conditions this disease is transmitted, so far as known, solely through the feeding of the beet leafhopper, Eutettix tenellus (Baker), the so-called "white fly." The serious damage of 1924 and 1926 has especially emphasized the necessity for more knowledge concerning the problem.

Circular No. 71 - Weeds: Losses, Agencies In Distribution, Nature, And Control, William Peterson, D. C. Tingey

UAES Circulars

There are in Utah a number of weeds considered to be unusually persistent and difficult to eradicate once they have become established. The most common in this group are wild morning glory, whitetop, Canada thistle, perennial sow thistle, and Russian knapweed, the last being one of comparatively recent introduction. The weeds in this group are quite generally feared and much talked of by farmers. They are feared because, if allowed to persist, they usually take possession of the soil and hinder the growth of farm crops. The discouraging fact about these weeds is their spread. Old infested areas are increasing …

Circular No. 72 - Brooding And Feeding Chicks, Byron Alder

UAES Circulars

The poultry raiser who does not plan and lay the foundation for a better flock each year is missing an opportunity to increase his financial returns and to make each year's poultry crop more secure. Under present conditions the profit made by a flock of hens is usually in direct proportion to the fall and winter egg production of the flock. Production during this period depends very largely on the success of the poultry raiser in developing each year's flock of pullets into strong, vigorous, mature birds. In other words, the number of eggs produced, the size of the eggs …

Circular No. 69 - Clean Milk And Its Production, E. G. Carter

UAES Circulars

Successful dairy farming is fast growing into an exacting profession, and in order to be successful the dairy farmer must not only recognize the value of good clean milk but must know how to produce it as well. Good milk, good butter, and good cheese are acknowledged to be in great demand, and each brings fair financial returns.

Since the beginning of the dairy industry one of the big difficulties has been that of obtaining clean milk and cream. By applying the best scientific methods in the manufacture of dairy products the ill effect of impure milk can be partly …

Circular No. 70 - The Agricultural Outlook For Utah, P. V. Cardon, W. P. Thomas

UAES Circulars

In preparing the following statement of Utah's relation to the national agricultural outlook for 1928, the writers have been guided by three fundamental considerations : (a) Utah is a livestock state; (b) feed production is the basis of Utah agriculture; and (c) definite physical, geographic, and economic limitations govern Utah's production of crops other than feed crops.

Bulletin No. 203 - Cattle Ranching In Utah: Report Of A Preliminary Economic Survey Of The Ranch Situations As Of 1925, William Peterson, P. V. Cardon, K. C. Ikeler, Geroge Stewart, A. C. Esplin

UAES Bulletins

The Mexican War ended in 1846, but the treaty of Guadalupe Hidalgo was not signed until 1848. Meantime, Utah was occupied by the Mormon pioneers, who having no land laws to guide them took land according to a plan furnished by Brigham Young. In Salt Lake City 10-acre blocks were divided into 8 building lots of 1 1/4 acres each. Just at the edge of the city were "five acre lots to accommodate mechanics and artisans; next beyond were 10-acre lots, followed by forty and eighty acres, where farmers could build and reside."

The publications of this Station are no longer sent to a general mailing list (except in cases of libraries and state editors) but are sent only on request. Therefore, copies of any of the publications listed will be sent without charge to those requesting them as long as the supply is available. However in the case of abstracts of scientific and technical papers the supply is very limited and the requests for these should be limited …

Circular No. 66 - Physical Curd Character Of Milk And Its Probably Relation To Infant Nutrition, R. L. Hill

UAES Circulars

A problem which must be met by many mothers is that of obtaining for their infants an adequate substitute for breast milk. The weaning period is a very critical time in the life of every infant. Its ability to properly digest and assimilate the food supplied will largely determine its state of health, provided it is kept free from infection.

Milk formulas for the feeding of infants are often made up to conform to certain fat requirements. Some infants apparently have difficulty in properly assimilating a milk with a high fat content. This may be due to a low fat …

Circular No. 67 - Rules And Regulations For The Fourth Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

This contest is conducted on a part of the Utah Agricultural College Farm near the experimental poultry yards. It is managed by the Poultry Department with an experienced poultry raiser in direct charge of the feeding and care of the hens in the contest. The buildings, grounds, and fences were built and furnished by the Experiment Station.

Bulletin No. 202 - Some Observations On Winter Injury In Utah Peach Orchards, T. H. Abell

UAES Bulletins

During the winter following the freeze, fruit growers in Utah were deeply concerned over the effects of the cold on their orchards, since it was observed that not only were fruit buds killed, but the tissues of the trunks, limbs, and twigs were turning brown. The question at once arose as to whether or not this browning indicated the approaching death of the trees. It was, therefore, considered important to determine, if possible, the nature and extent of the damage, to discover any factor which might have favored or lessened the injury, and finally to offer suggestions to the orchardist …

Bulletin No. 200 - Maintaining Potato Yields By Hill Selection, George Stewart, D. C. Tingey

UAES Bulletins

Utah's agriculture has passed definitely out of its pioneer period. Single-cropping, whether to wheat, to potatoes, or to sugar-beets, during the past few years has been forced from its last stronghold. The earmarks of mature agriculture are already visible. Of these, there are four important ones: (1) the production of both crops and livestock; (2) careful manuring and irrigation; (3) good crop rotations; and (4) the use of high-grade parental stock, that is, prepotent sires for livestock and strong and healthy seed for crops.

Bulletin No. 199 - Mutual Irrigation Companies In Utah, Wells A. Hutchins

UAES Bulletins

Cooperation has been an important factor in the development of agriculture under irrigation in Utah. The Mormon pioneers in the Great Basin were the first Anglo-Saxons to practice irrigation on an extensive scale in the United States; hence, it is significant that from the first their irrigation work was accomplished largely as a result of community effort. Private diversions of water there were, of course, even in the earliest times, but for years they were quite out of place in an environment that took quick toll of those individualists who scorned the protection of numbers and refused to cooperate. The …

Bulletin No. 201 - Economic Insects In Some Streams Of Northern Utah, James G. Needham, Reed O. Christenson

UAES Bulletins

The food of trout in our mountain streams is mainly insects. It is, in part, land insects that fall on the water and are taken as they float upon its surface, but in a much larger part it is insects that grow up in the water and are taken in their immature stages. These are the constant and dependable food-supply. They have been little studied hitherto. This bulletin is a report of a preliminary examination of some Utah streams, made for the purpose of discovering what forms of life are present in the streams and in what relative abundance. Some …

Circular No. 63 - Tomato Culture In Utah, A. L. Wilson

UAES Circulars

The object of this circular is to point out in a general way the essential considerations for successful tomato-growing in Utah. It has become necessary because of the increasing importance of this crop in the state as well as in the United States.

Bulletin No. 198 - Report Of The Director: For The 18-Month Period From January 1, 1925, To June 30, 1926

UAES Bulletins

In the following report of the Utah Agricultural Experiment Station for the past eighteen months, record has been made in as much detail as space would permit. The text is intended to give the present status of the projects under consideration and to record the changes and additions since the last report.

Therefore, copies of any of the publications listed will be sent without charge to those requesting them as long as the supply is available. However, in the case of abstracts of scientific and technical papers the supply is very limited and the requests for these should therefore be limited as far as possible only to those …

Bulletin No. 197 - The Pear Leaf Blister Mite As An Apple Pest, I. M. Hawley

UAES Bulletins

The blister mite is a pest of foreign origin, that has been in the United States for many years. It was introduced into this country, probably from Europe, sometime before 1872, and by 1894 it was rather general in its distribution thruout the United States and Canada. At the present time this mite is a serious pest of apples in many of the fruit-growing sections of Western America. The blister mite was first reported in Utah by Hedrick as early as 1898. During the last few years it has been abnormally abundant in some parts of Utah.
