Circular No. 91 - Establishing Snow Courses And Making Snow Surveys, George D. Clyde

UAES Circulars

The major portion of the annual precipitation in the semi-arid west falls as snow. It piles up in the mountains and forms the main source of the water in the creeks and rivers draining the mountainous areas. Some of these streams flow the year around while others and intermittent, flowing only as long as the snow in the mountains lasts. The water-supply for irrigation, power development, and municipal purposes is derived largely from winter snows. A knowledge of the extent of the snow cover and its water content is, therefore, necessary for the proper utilization of this great natural resource. …

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 …

Bulletin No. 222 - A Quarter Century Of Dry-Farm Experiments At Nephi, Utah, A. F. Bracken, George Stewart

UAES Bulletins

Utah is naturally an arid state with precipitation varying from 3.71 inches at Wendover, located in the vast desert region on the western border, to more than 40 inches on some of the mountain ranges. Desert and mountain areas and other untillable land combined total about 95 per cent of Utah's land area. The remaining 5 per cent constitutes all the land which will yield to cultivation either by irrigation or by dry-farming.

Durinog the 76 years that dry-farming has been practiced in Utah, many change in tillage practices, cropping systems, crops, and crop varieties have taken place in keeping …

Circular No. 90 - Swine Production In Utah, Harry H. Smith

UAES Circulars

During the last 20 years there has been a marked change in the type of hogs from the short-legged, wide-bodied or "hot-blood" type to a longer, somewhat more narrow-bodied, "leggier" type. For development of size in hogs they must have (1) length and depth of body, (2) length of leg, and (3) large but not coarse bones. The long-bodied rather "leggy" pig grows rapidly and makes the larger hog. While the modern hog is still a lard hog, it is not as thick and broad as were its predecessors. It is logical to assume that the hog of the future …

Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack

UAES Bulletins

For 17 years the late Dr. Herbert J. Pack, former Station Entomologist, made a study of the reptiles and amphibians of Utah. His original idea was to publish a comprehensive treatment of the snakes and lizards of his state, and whenever opportunity was afforded collected data on their distribution, habits, and economic importance. At the time of his death, on January 5, 1930, many notes and drawings of lizards were left; a manuscript on snakes, presented for his master's thesis to the Utah State Agricultural College in 1923, was also in his possession. Bulletin 221 contains essentially the information presented …

Circular No. 89 - Rules And Regulations For The Seventh Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

This contest is conducted on a part of the Utah State Agricultural College Farm near the experimental poultry yards. It is managed by the Poultry Division 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 Agricultural Experiment Station.

The purpose of the contest is (1) to impress on the poultry raisers the importance of greater care in the selection of their fowls and in the value of proper feeding and housing, (2) to stimulate a greater interest in the …

Circular No. 86 - Coccidiosis Of Chicken, D. E. Madsen

UAES Circulars

Coccidiosis is a highly contagious disease of chickens and other fowls which is widespread and destructive, especially to half-grown chickens. The heaviest losses occur in chicks from 2 to 10 weeks of age. Just prior to and during their first laying season, pullets sometimes become affected with the disease in a chronic form. The cause is a microscopic protozoan parasite, the oocyst form of which is present in the droppings of diseased birds in large numbers. At least three species of the parasite have been recognized in fowls. The severity of the outbreak is thought to be determined by the …

Bulletin No. 219 - Twenty-Eight Years Of Irrigation Experiments Near Logan, Utah: 1902-29, Inclusive, D. W. Pittman, George Stewart

UAES Bulletins

Since 1902 irrigation experiments have been a major part of the research activity on the Greenville (Central) Experimental Farm near Logan, Utah. The experiments have been concerned mainly with the effects of different quantities of irrigation water, the minimum water requirement of crops, and the effects of different seasonal distribution of the water. This publication aims to give a brief summary of this work as it relates to crop yields as well as the more recent results up to and including 1929.

Bulletin No. 217 - Prices Of Farm Products In Utah, W. Preston Thomas

UAES Bulletins

The purpose of this bulletin is to indicate, by means of price data, the relative position of Utah's agriculture, the agriculture of the United states as a whole, and industrial enterprises. It Is the aim to analyze these price data in order to indicate the relationship existing between the various commodities and major enterprises. Through comparative price series an attempt has been made to present in tabular and graphic form a general picture of these enterprises for a series of years.

Bulletin No. 218 - The Alfalfa-Seed Chalcis-Fly In Utah: 1926-29, Inclusive, Charles J. Sorenson

UAES Bulletins

During the past 10 or 15 years alfalfa-seed has constituted the major crop in western Millard County and in most of that portion of the Uintah Basin which is situated in Utah. In these sections of the state various natural conditions generally have been favorable for seed production. Within the last five years seed growers have thought that one of the principal limiting factors of the industry has been the alfalfa-seed chalcis-fly. Accordingly, a preliminary survey in the seed districts of the state was made in the fall of 1925 by the Utah Agricultural Experiment Station.

The greater part of …

Circular No. 87 - Raising Dairy Calves, George B. Caine

UAES Circulars

Too much importance cannot be given to the number and kind of calves raised. The life of an average cow is 6.5 years. To maintain the present number of cows in Utah about 15,385 heifer calves should be raised annually. One-half of all calves born are males and are usually disposed of in a few weeks; the other 50 per cent are females from which selection must be made to maintain the herds. In many parts of Utah the number of dairy cows should be increased and probably the best way to accomplish this is to raise carefully selected calves.

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.

The Use Of Chlorates For The Eradication Of Certain Perennial Weeds In Utah, Lionel Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Perennial weeds have retarded agricultural progress, since their first appearance in cultivated fields. They have grown and survived the destructive efforts of the farmer and agricultural scientist, over a great period of time. Many farmers have become discouraged and much valuable land has lain idle because of this wasteful weed persistence.

These dismal consequences have stimulated constant effort at experimental stations to discover more effective methods of battling the pest. The use of chemicals has been one of the most prominent weapons and, of the most recent chemicals tried, the chlorates are the most promising.

Bulletin No. 216 - Notes On Miscellaneous Insects Of Utah, Herbert J. Pack

UAES Bulletins

Doctor Pack, as station entomologist, was studying many problems, all of which could not receive constant attention. Consequently, much of the information recorded is far from complete but has value as a record of occurrence or as it bears on phases of the life history of forms present in this area. The following bulletin consists of notes on the various species of insects in Utah.

Bulletin No. 215 - Cost Reduction In Dry-Farming In Utah, P. V. Cardon

UAES Bulletins

Major economic influences, known to be affecting farming generally throughout the United states, are forcing the adoption of cost-reduction methods in dry-farming practice in Utah.

The methods of cost reduction that are being adopted include (a) cultural methods involving the control of weeds, preparation of the seedbed, the treatment of seed for the control of smut, and the use of superior strains or varieties of wheat, all of which are expected to reduce the cost per bushel by increasing the acre-yield; and (b) the more economical use of labor and equipment on the area farmed. The area farmed may be …

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. 83 - Planning, Planting, And Caring For Young Orchard, Francis M. Coe

UAES Circulars

Fruit growing offers many advantages to the farmer of the intermountain west, chief of which is the high return possible from a relatively small farm. Few crops will give as high an acre-yield or return as a properly located and managed orchard. Acre-yields of from 500 to 800 bushels of apples, pears, or peaches are not unusual. The work is pleasant, interesting, and healthful, as well as remunerative when properly conducted. Fruit Growing Attractive, Profitable

Leaflet No 256 - Climbing Cut-Worm Or Tomato Moth (Chlorodea Obsoleta), L. J. Newman

During the past spring caterpillars of various kinds have been unusually prevalent. In some instances they have been so numerous as to constitute a plague.

The caterpillar most in evidence was the larva of the Climbing Cut-worm or Tomato Moth.

Propagation Of Aquatic Game Birds, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The propagation of aquatic game birds in the United States is a small but growing industry. Approximately 50,000 wild ducks and 5,000 wild geese constitute the present annual production. Some of these birds are bred by individual or organized sportsmen for their own use, some by fanciers because of their interest in the birds, and others by breeders for sale. The market for two species, the mallard duck and the Canada goose, demands birds for use in restocking, for decoys, and for food. Sale for food is the exception rather than the rule, and is to the better class of …

Homes For Birds, E. R. Kalmbach, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Birds appeal strongly to the interest and affection of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.

Birds feed upon practically all insect pests. They are voracious, able to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.

For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their numbers. …

Circular No. 82 - Lamb Slaughtering And Cutting, Harry H. Smith

UAES Circulars

The old saying that "the shoemaker's wife goes without shoes" might be changed to read "the lamb raiser and feeder of the west does not eat lamb." About three-fourths of the population of the United states is east of the Mississippi River, and about 90 per cent of all the lamb and mutton produced in the United states is consumed east of the Mississippi. It has been observed, both on the farms and in towns, that a large percentage of people in the sheep sections of the west have tasted neither lamb nor mutton.

Circular No. 81 - Beef Slaughtering, Cutting, And Curing, Harry H. Smith

UAES Circulars

Many farmers follow the practice of occasionally slaughtering a steer, a heifer, or a calf for home use. When this practice is followed the farmer is assured of getting meat of high quality. Experience has taught him that he is not always :able to get meat at a local market which equals in quality that which he slaughters on his own farm. The butcher is not at fault as he usually handles the quality of meat his customers desire and will accept.

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. 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.
