UAES Bulletins

President E. G. Peterson

Sir: I have the honor to transmit the report of the Utah Agricultural Experiment Station for the biennium ending June 30, 1932. This report includes the reports of the various departments as well as other information pertaining to the work of the Experiment Station during this two-year period.

Respectfully submitted, P. V. CARDON, Director.

Bulletin No. 227 - Soft-Curd Milk, R. L. Hill

UAES Bulletins

Data on the early studies on the curd character of milk are found in Utah Agricultural Experiment Station Bulletin 207 and, therefore, are not included here. The key to research in this field came to light with the development of the "Hill Test," the results of which were first published in 1923. This test furnished a means of quantitatively measuring the difference in curd character of various milks.

The term "soft-curd" milk originated with R. L. Hill to describe milk which on coagulation with pepsin or rennin forms a curd that is soft and clabbery in consistency, differing widely from …

Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick

UAES Bulletins

For a number of years many tons of sprayed or dusted hay have been fed successfully to livestock by stockmen interested in controlling the alfalfa weevil; nevertheless. the supposed cases of poisoning that have been reported naturally have caused concern among feeders.

Further confusion on this question has resulted from reports on studies designed to determine the effect of lead arsenate instead of calcium arsenate.

Whether the lead in lead arsenate has been a more injurious agent than the arsenic, of course, is difficult to state. Most of the experiments performed in the feeding of sprayed or dusted hay have …

Circular No. 85 - Chlorosis Yellowing Of Plants: Cause And Control, F. B. Wann

UAES Circulars

Chlorosis is a disease of plants, the characteristic symptom of which is the yellowing of the leaves. The disease is of sporadic but widespread distribution in Utah and the aggregate losses caused by it are undoubtedly greater than those of any other one disease. Not only are many plants killed, or weakened to such an extent that only inferior crops are produced, but many areas of land which might otherwise support profitable orchards have been abandoned or planted to other crops because of the disease.

Circular No. 84 - Building Young Deciduous Fruit Trees, Francis M. Coe

UAES Circulars

The modern fruit tree in a commercial orchard, to survive in present-day competition, must bear heavy crops. The mechanical strength which determines whether it can hold its heavy load successfully or whether it will be broken down and become a liability to its owner is determined to a large extent by the training it has received the first two or three years after planting.

Circular No. 80 - Domestic Slaughtering, Cutting, And Curing Of Pork, Harry H. Smith

UAES Circulars

The practice of slaughtering hogs on the farm is being followed rather extensively by the farmers of this state. It is an economic practice and should be more generally followed because by this practice a supply of meat is available throughout the year. In all ages meat has been the principal article of diet of the ruling races. It is a natural and necessary part of man's diet. The races of people who have not included meat in their diet are today numbered among the weaker and more backward nations.

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. 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. 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.

Sporogenesis In Botrichium Virginianum Swartz, Lewis Abel Stocking

Bachelors’ Theses

The earliest resultful work done in Pteridophytes, very closely similar to Botrychium Virginianum Swartz, was the work of Goebel (1890) on the Ophioglossales. Bower (1890) followed Goebel in his work on the Ophioglossales. He completed a work in 1896, which according to Burlingame (1907), who also did valuable work on the Ophioglossales, is the most comprehensive and satisfactory that has thus far been done. This work had a stimulating effect upon the early study of Botrychium Virginianum Swartz because of the almost entirely similar histology of the two plants. Burlingame’s (1907) work in the Ophioglossales, was done in 1907. He …

Branched Cells Of Pteris Cretica L., Var. "Albo-Lineata, Hort And Pellaea Viridis (Forksk) Prantl", Mary Elizabeth Trechter

Bachelors’ Theses

The fern gametophyte offers a large field for experimental work, not only in the reproductive processes but in the development of prothallia from the germination of the spore. The ordinary fern spore germinates on soil or in water. Prothallia, which have formed branched cells, have been found by a number of workers, and attempts have been made by some to explain the cause of the branching.

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 …

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. 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.

Grazing Periods And Forage Production On The National Forests, Arthur W. Sampson, Harry E. Malmsten

Aspen Bibliography

Stockmen in the West have always had confidence in the adequacy of the native forage crop to provide pasturage for their livestock. Indeed, under normal climatic conditions this enormous natural resource has not failed the grazier, except where it has been called upon to meet unreasonable demands. The productivity of the range has declined sharply, however, wherever the requirements of plant growth have been disregarded for many years in succession. Where there has been too early or too frequent and to heavy grazing, undue trampling, or some other unsatisfactory feature of range use, the results have been uniformly bad. Many …

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.

Bulletin No. 196 - The Fruit Tree Leaf Roller And Its Control By Oil Sprays, I. M. Hawley

UAES Bulletins

When the fruit tree leaf roller is present in large numbers in an apple orchard it i the most destructive apple insect in the state. Fortunately, it is not a pest of general occurrence. Tho this insect is known to occur from Cache Valley south to Beaver, serious losses from its ravages have been restricted to occasional orchards within the infested territory.

Bulletin No. 195 - Field Studies Of Sugar-Beet Nematode, George Stewart, A. H. Bateman

UAES Bulletins

The sugar-beet nematode has now become of importance in Utah. It occurs in spots in practically all of the older beet-growing districts and in a few parts of the state in much larger areas. The intensity of infestation varies from mere traces to nearly complete occupation. One of the areas of severe infestation in Utah on a large area is in the Lewiston district, of northern Cache Valley. The survey here reported was undertaken in order to find the extent of nematode infestation in Cache Valley and the possibility of its control by ordinary cultural practices.

Circular No. 60 - Seed-Potato Treatment: For The Control Of Four Common Diseases Rhizoctonia, Scab, Blackleg, Dry-Rot, B. L. Richards

UAES Circulars

Potato diseases are a constant menace to the Utah potato crop. During the 4-year period from 1920 to 1924 losses sustained from disease averaged 19.5 per cent, or approximately one-fifth of the entire state crop. This means that every year a large percentage of the seed planted is useless and that one-fifth of every acre planted to potatoes is wasted. Again, labor in the way of planting and in cultivation is used to poor advantage, and finally the grower suffers a direct financial loss which frequently eats up his expected profit.

Circular No. 58 - Potato Production In Utah, George Stewart

UAES Circulars

Potatoes were the first crop planted in Utah. In July 1847, the Mormon pioneers turned the water from City Creek over the parched land near what is now the center of Salt Lake City. The ground was then broken and sown at once to potatoes. Only a small yield was obtained but this helped materially to eke out the meagre food supply until the harvest of 1848. During the several hard years that followed potatoes were among the most important foods for the pioneer settlers. Since then they have held a prominent place in the agriculture of the state.
