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.

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.

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 …

Absorption Of Nutrients From Subsoil In Relation To Crop Yield, John W. Crist, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Investigations of the development of root systems of native and crop plants have been pursued for a number of years at the University of Nebraska. The gradual intensification of this work has led to a type of experimentation designed to discover the nature of the activities of roots at great depths in relation to absorption of water and nutrients. In the present investigation the effects of absorption of nutrients from deep levels upon quantity and quality of yield were determined. Studies on the amounts of water and nitrates removed by crops from various soil levels were begun in i919, but …

Range And Pasture Management, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Sampson's range and pasture management is an excellent example of the application of the principles of ecology to the solution of economic problems. In grazing experiments it is of equal importance to know what is happening to the stock and to the vegetation. This emphasizes the fact, which ecologists are coming more and more to recognize, that animals, both wild and domesticated, have a proper place in the environment and that they play an important role in modifying the vegetational development. This volume consists largely of first-hand information obtained by the author during fifteen years of intensive pasture investigations for …

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 …

A Study Of The Flowering And Fruiting Habits Of The Delicious Apple, Emery R. Ranker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the most disagreeable and at the same time the most unprofitable features of commercial apple production is the tendency of most apple varieties to "take a rest" every other year in order to regain the strength given to the production of a very heavy crop the previous year, and thus be able to repeat the process of heavy production the following year. This process is referred to as "off-year" or alternate bearing. Various causal relationships have been suggested , from time to time, by the different workers in the field but the suggestion now most generally accepted, and …

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 …

Bulletin No. 182 - The Net Duty Of Water In Sevier Valley, Orson W. Israelsen, Luther M. Winsor

UAES Bulletins

The Sevier River is one of the most important sources of irrigation water in Utah. It rises in two main branches. The south fork rises in Kane County and flows almost due north to Junction in Piute County, where it joins the east fork, which rises partly in Garfield County and partly in Sevier County. The Garfield County branch of the east fork flows north, and the Sevier County Branch flows south to Coyote where the two tributaries join and flow westward into Junction. From Junction, the river flows northward past Marysvale, Sevier, Richfield, Salina, Gunnison, and Mills, where it …

Circular No. 46 - Thirty Years Of Agricultural Experiments In Utah, F. S. Harris, N. I. Butt

UAES Circulars

The Utah Agricultural Experiment Station has been established over thirty years. During this time more than a hundred experimenters have worked on the staff, each one contributing something to aid in the researches that have been conducted. During the first few years regular annual reports were published, but during recent years no such reports have been issued. The results of the work of the Station have been published in station bulletins and circulars and in various technical journals.

Since there is no publication or series of publications that records all the activities of the Station it was thought desirable at …

Circular No. 45 - Alfalfa Production Under Irrigation, George Stewart

UAES Circulars

Alfalfa was first planted and cared for by half-civilized man long before any history was written. In spite of the fact that its line of descent has come thru the Medes and Persians by way of the Greeks, the Romans, the Moslems, and the Spaniards,--in spite of long sojourns in many lands, the heritage is still undefiled. Instead of losing in adaptability, possibly long centuries of trial have made it more fit. At any rate, here it is: high in power to yield, rich in power to nourish.

With its deep roots it laughs at drought and mellows up the …

Bulletin No. 180 - The Irrigation Of Alfalfa, F. S. Harris, D. W. Pittman

UAES Bulletins

In the United States alfalfa-growing has gone hand in hand with the development of irrigation. Alfalfa did not become an important crop in the country until after irrigation began to be practised in the West. Very soon after the pioneers reached Utah, alfalfa was brought to the state where it found conditions well suited to its growth. Wherever settlement extended alfalfa was raised as one of the most important crops, and finally from the West it has spread eastward into the humid parts of the country.

Bulletin No. 179 - Apple Candy: A Commercial Use For Cull Apples, T. H. Abell

UAES Bulletins

Utah annually produces many tons of apples that never reach the consumer. These apples remain on the farm for various rwasons: (1) because there are not adequate marketing facilities, (2) because the fruit is of inferior quality, (3) because orchard units are too small for buyers to consider, and (4) because home orchards are so large that the crop cannot be utilized. On the other hand, apples of inferior quality go to the market alongside apples of high quality. The result is a lowering of the price of apples in general and dissatisfaction on the part of the retailer and …

Bulletin No. 177 - Some Types Of Irrigation Farming In Utah, E. B. Brossard

UAES Bulletins

As ordinarily used "type of farming" suggests general contrasts in the nature of farm business. The bases used in making these contrasts are: (1) sources of farm income, (2) number of farm enterprises, (3) amount of labor, capital, and management applied to each acre of land, and (4) farm practice with reference to maintenance of soil fertility. When based on sources of farm income, farms are classified as grain farms, hay farms, fruit farms, dairy farms, etc., according to the proportionate magnitude of the income from the different sources. When the number of farm enterprises is used as the basis, …

Bulletin No. 176 - Potato Improvement By Hill Selection, George Stewart

UAES Bulletins

Potatoes are such an important food and are grown on so many farms in Utah that any method of permanently improving the crop is highly desirable. Commercial producers can of course capitalize any practical method of potato improvement.

This field of experimentation is not new, for many workers have attempted to improve the potato crop by selection. Success, however, has been neither uniform nor always appreciable; many of the experiments were of short duration, and many were not conducted on a sufficiently large scale to be good tests. It is apparent from this meager statement that the possibilities" of potato …

Circular No. 43 - Feeding Work Horses, W. E. Carroll

UAES Circulars

The intelligent feeding of the work horses of the State of Utah would save each year thousands of dollars in feed and prevent sickness and death of hundreds of horses.

In Circular 32 of this station a brief discussion is given of some of the more theoretical aspects of the feeding of farm animals as they might apply in general to all classes of livestock. Consideration is given to such questions as the composition and digestibility of feeds, the uses to which the digested portions are put in the animal body, the calculation and balancing of rations, how to judge …
