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. 61 - Rules And Regulations For The Third Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

This contest is located 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. 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. 59 - Control Of Stinking Smut Of Wheat With Copper Carbonate, B. L. Richards, A. F. Bracken

UAES Circulars

Stinking smut or bunt of wheat is an ever-present and destructive disease in the wheat fields of Utah. During the past season (1925) this disease was especially prevalent, causing losses in certain fields of from 25 to 50 per cent, not counting the loss to the grower in reduced grade of grain. In the threshing of smutty wheat there is also the risk of loss from smut explosion. Almost every season cases of this sort are reported. In addition of all of the wheat tested by the U. S. Grain Inspector at Logan for Northern Utah and Southern Idaho 30 …

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.

Circular No. 57 - Economy In Harvesting Sugar-Beets, George Stewart

UAES Circulars

During sugar-beet harvest the farmer has two big opportunities to increase his income from the beet crop. No great amount of extra labor is entailed in either case, and yet the profits are written in large figures. To neglect getting the most from beets at harvest time after a toilsome and expensive production seems wasteful. Farmers are urged to give full consideration to these two phases of beet harvest: (1) The making of beet-top silage from fresh beet tops. Large yields of good quality feed may thus be secured. (2) The preventing of losses in tonnage due to evaporation. Poor …

The publications of this Station are no longer sent to a general mailing list (except in case of libraries) 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 case of abstracts of scientific and technical papers the supply is very limited and the requests for these should be limited as far as possible only to those who are especially …

Circular No. 55 - Rules And Regulations For The Second Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

The support given the first Utah Intermountain Egg-Laying Contest by the poultry breeders of this section and the very unusual records obtained during this contest to date seem to justify this announcement of the rules and regulations for the second contest to begin November 1, 1925. The contest is located 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 …

Bulletin No. 194 - The Influence Of Storage On The Composition Of Flour, J. E. Greaves, C. T. Hirst

UAES Bulletins

There is quite a general belief among millers, bakers, and the laity that flour improves on ageing. However, there is no definite information as to the time requisite for this improvement nor whether it reaches a maximum and then deteriorates. The information is no more exact as to the changes which occur during the ageing process or the conditions which govern them. We have found no reference in the literature where bad effects have resulted from storage, provided a highly-milled, sound flour is stored in dry, well-ventilated rooms free from odors (20). The results which have been reported point to …

Circular No. 54 - The More Important Insects Injurious To The Sugar-Beet In Utah, I. M. Hawley

UAES Circulars

Insects destroy many sugar-beets in Utah. In some years the incomes of the farmers of the state are greatly reduced because of the ravages of these pests. This circular has been written in the hope that the more important information about the insect pests of this valuable crop may be more readily available to the beet growers of the state.

The insects treated in this paper are grouped under two main heads. In the first division are included those insects affecting the tops or foliage of the beet. In the second division are those insects that feed on the roots.

Bulletin No. 193 - Cache County Water Conservation District No. 1, William Peterson, G. D. Clyde, D. S. Jennings, M. D. Thomas, Karl Harris

UAES Bulletins

Cache County Water Conservation District No. 1 lies on the west side of the valley about eight miles from and a little northwest of Logan, Cache County, Utah. Figure 1 shows the location of the project with respect to Salt Lake, Ogden, Brigham City, Logan, and Cache County. Cache County, with a population in 1920 of 27,000 people, is located in the north-central part of the state and occupies the greater part of the fertile Cache Valley. Cache County Water Conservation District No.1 includes 8490.78 acres (of which 7373.38 acres are allotted water) and extends from Bear River and its …

Bulletin No. 192 - Biennial Report Of The Director: For The Years 1923 And 1924

UAES Bulletins

No report (either annual or biennial) of the work of the Utah Agricultural Experiment Station has been published separately since 1906. There has been so much inquiry regarding the present status of research projects that a brief report at this time is considered opportune. The report is an attempt to give the reader a brief but concise and comprehensive survey of the research work now under way at the Utah Agricultural Experiment Station as well as a brief description of the work being attempted on each of the experimental farms.

Circular No. 53 - Summary Of Publications

UAES Circulars

This circular contains summaries of the publications of the Utah Agricultural Experiment Station issued since September 1923. The publications of this Station are no longer sent to a general mailing list (except in the case of libraries) 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.

Bulletin No. 189 - Ridding The Land Of Wild Morning Glory, George Stewart, D. W. Pittman

UAES Bulletins

"Morning glory" is the common name for one of the worst weeds found in Utah. On account of its general resemblance to a cultivated plant spoken of as morning glory, the weed is frequently and more correctly known as the "wild morning glory." Since everyone who handles farm land knows the plant, a description of it is unnecessary. It may not be amiss, however, to mention that the name probably comes from the fact that the showy, funnel-shaped flowers are open only in the morning, being folded within the sepals after midday or earlier in hot, dry weather.

Bulletin No. 190 - Corn Silage In A Dairy Ration, W. E. Carroll

UAES Bulletins

In 1914 a study of the value of corn silage in the dairy ration was undertaken at this station. The first phase of the general question to receive attention was the effect of adding silage to a basal ration of alfalfa hay and grain.

Circular No. 52 - Rules And Regulations For The Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

The contest will be located on a part of the Utah Agricultural College Farm near the experimental poultry yards. It will be managed by the Poultry Department with an experienced poultry raiser in direct charge of the feeding and care of the hens in the contest. It is hoped that the entry fee and the sale of eggs will pay for the expense of the contest. The buildings, ground, and fences will be built and furnished by the college.

Bulletin No. 188 - Maintaining The Productivity Of Irrigated Land, D. W. Pittman

UAES Bulletins

It is almost universal history that in farming a newly developed region no attention whatever is paid to maintaining the fertility of the soil. This is natural for two very obvious reasons. In the first place the pioneer has other and more pressing problems in the "subduing" of the new land, and in the second place such virgin soils are generally blessed with a great abundance of native fertility. New lands in an arid or semiarid region are usually especially fertile because they represent a long-time accumulation of fertility which is not possible under humid conditions. Since in a humid …

Circular No. 51 - Foot-And-Mouth Disease, H. J. Frederick

UAES Circulars

The following is printed that the seriousness of the foot-and-mouth disease outbreak might be apparent to the farmers and ranchmen of Utah, that the importance of the quarantine regulations might be emphasized, that precautionary methods might be adopted by each individual concerned, that the disease might be recognized should it occur, and that each stock man of the state might see the importance of immediately reporting to the State Veterinarian or to a veterinarian in his locality or to the Utah Agricultural Experiment Station.

Circular No. 50 - Brooding And Feeding Chicks, Byron Alder

UAES Circulars

Raising baby chicks seems a comparatively simple matter to some, yet there are more failures in poultry-keeping due to inability to raise good, vigorous pullets than to any other one cause. The number of eggs produced, the size of the eggs (within certain limits), and the profit made from a flock of hens is often determined very largely by the success in brooding the chicks and developing the pullets into strong, vigorous hens. Many who try to raise chicks are not successful because they fail to realize that a baby chick is a "real baby". They cannot survive with careless …

Circular No. 49 - This Public Domain Of Ours, George Stewart

UAES Circulars

In Utah are somewhat more than fifty-two and a half million acres of land. Of this about five million acres are in farms, but only 1,371,000 acres, or 2.6 per cent, are irrigated. In addition there are about 344,000 acres under dry-farm culture, making a total of 1,715,000 acres of improved land. This leaves all of Utah's fifty-two and a half million acres, except about 3.5 per cent, to be utilized by some means other than crop-growing. There will be some addition of new lands not in farms and some development in unimproved farm lands, but when every development that …

Circular No. 48 - Rural Credits In Utah, E. B. Brossard

UAES Circulars

The subject of rural credits is of interest to farmers, bankers, investors, and all others concerned about public welfare. This circular is written for the purpose of giving general information about agricultural credit conditions existing at the present time, with special reference to mortgage credit in Utah and the Federal Farm Loan System as now amended. The passage of the Federal Intermediate Credits Act, approved March 4, 1923 makes this an opportune time to check up on the situation.

Bulletin No. 186 - Irrigation Experiments With Sugar Beets, F. S. Harris, D. W. Pittman

UAES Bulletins

A previous bulletin of this station gives the results of an experiment on the irrigation of sugar-beets continuing for five years. Since this experiment was deemed of sufficient importance to merit our best attention and since the climatic conditions which largely determine what is the best irrigation practice may not for so short a period properly represent the average of the community, it was thought advisable to continue the experiment, with certain modifications, for an additional five years. This bulletin reports the results of these last 5-years' work together with such general conclusions as can be drawn from the entire …

Bulletin No. 187 - Irrigation Experiments With Potatoes, F. S. Harris, D. W. Pittman

UAES Bulletins

In a previous bulletin of this station are given the results of an experiment on different irrigation treatments of potatoes continued for five years. In view of the importance of the potato crop and of the importance of having it properly irrigated it was considered advisable to continue the experiment, with certain modifications based on experience, for a further period of five years. This total period of ten years should include most of the climatic variations which are common in this locality, and by eliminating the more unsatisfactory irrigation systems a closer approximation to the best system should be found. …

Bulletin No. 185 - The Influence Of Nitrogen In Soil On Azofication, J. E. Greaves, D. H. Nelson

UAES Bulletins

Many soils of the arid west have a rich active azofying flora. This is due in no small measure to their composition. They are high in calcium and magnesium carbonate and contain a good supply of available phosphorus and potassium but have a low nitrogen content. They are poor in organic carbon; hence, their native supply of energy is limited. It is well-known that a liberal supply of rapidly decaying organic matter is beneficial, and this is being supplied to some soils in the form of manures. This will increase the nitrogen content of the soil. What effect will this …

Bulletin No. 184 - A Farm-Management Study Of The Great Salt Lake Valley, George Stewart

UAES Bulletins

This survey had for its purpose the study of farm organization in Great Salt Lake Valley. It is hoped that some conclusions may have been reached as to how to improve farming conditions. The records were taken during the summer of 1915 and consequently represent the farm business for 1914. Ordinarily the period of time that has elapsed since the records were taken would be too long to justify their being published. In view of the fact, however, that the World War began in 1914 and that its effects on the prices of farm products lasted until 1921, it is …

Bulletin No. 183 - Water-Holding Capacity Of Irrigated Soils, Orson W. Israelsen, Frank L. West

UAES Bulletins

All information that will 'enable the irrigator to use water economically is valuable to arid-climate agriculture. In many arid-climate regions, including the western part of the United States, excessive waste of water occurs in the irrigation of highland porous soil areas, as a result of lack of information concerning the capacity of the soil to hold water. Following the waste of water on the uplands by excessive percolation through open soils, vast lowland areas are rendered partially or wholly nonproductive by water-logging. To illustrate, a gravelly bench soil four feet deep, if underlain by a coarse open gravel to a …

Bulletin No. 178 - The Irrigation Of Barley, F. S. Harris, D. W. Pittman

UAES Bulletins

The proper use of irrigation water is one of the most important problems of every comnunity and of every farmer in an irrigated district. The irrigation farmer has largely under his control one of the most important factors in determining the yield and quality of his crops and one over which all other farmers have little control at all. On the other hand, in an arid district there is generally less available irrigation water than is needed to give the optimum amount to all the land, or if one region receives an excess there is generally an accumulation of alkali …

Circular No. 47 - Celery Culture For Utah, T. H. Abell

UAES Circulars

At one time practically all the celery consumed in Utah was shipped from California and eastern states. It was soon discovered, however, that celery could be raised in Utah, and as the population increased more and more acres were utilized in the production of this crop. Very little found its way to the outside markets, but what little did get out was well received because of its very high quality. Men who travel say that "Utah Celery" on the menu on trains and in hotels means the best there is in celery.

Within recent years several carloads have been shipped …

Bulletin No. 181 - Duty-Of-Water Investigations On Coal Creek, Utah, Arthur Fife

UAES Bulletins

Coal Creek flows from the west slope of the part of the Wasatch Mountain range which is located in the southeast part of Iron County, Utah. Its drainage area is almost 100 square miles.

Seasonal and daily stream-flow fluctuations are very pronounced. During the high water of spring the flow has reached more than 600 second-feet. At the time of high water, the daily fluctuations are the greatest. During the low water season in July and August, the flow has dropped as low as 12 second-feet since 1917, when accurate records were first kept; and, from the accounts of early …
