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 …

Haynes, Irene Dunne, Selma Rongstad, Geo H. Valentine, M. R. Benedict, J. C. Holmes, Ralph L. Patty, F. E. Mccall, G. S. Weaver, Manley Champlin, A. L. Ford

SDSU Extension Circulars

The past year has been filled with unusual activity and interest along the different phases of agricultural extension work. The demand for the services of the different extension workers has greatly increased, so much so that it has become a problem as to how their time may be best assigned to accomplish the most.
Extension work is based upon cooperation. The counties, state, and government cooperate in finding the problems and in solving them. Some of these agricultural and rural problems may be solved in the local community; others need the assistance of the whole county; other problems, again, are …

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 …

Bulletin No. 172 - The Value Of Barnyard Manure On Utah Soils, F. S. Harris

UAES Bulletins

New countries rarely appreciate the value of barnyard manure. It is not until the soil begins to be depleted of its fertility and the yield of crops begins to decline that manure is given the attention that its value justifies. In new countries it is not uncommon to see manure hauled into a rut in the road or left in scattered heaps along the roadside or the ditch bank. Often a year's accumulation of manure is drawn out of the barn or corral in scrapers and added to a pile containing the accumulation of previous years.

Bulletin No. 171 - Alfalfa Seed Growing And The Weather: With Particular Reference To Conditions In Utah, J. Cecil Alter

UAES Bulletins

The demand for alfalfa seed has far outrun domestic production. Since the labor and expense of producing the crop are light, and the profits attractive in favorable years, a desire is manifest wherever alfalfa is grown, to save a crop for seed whenever the meteorological elements favor its setting and maturing. Climate is generally acknowledged to be the limiting factor in alfalfa seed production, and the current weather the major factor affecting the yearly yields.

Circular No. 41 - Soil Alkali, F. S. Harris

UAES Circulars

The farmer of the West is likely to be very much upset at the mention of alkali, mineral, or salt, in connection with his land. These various names are applied to a condition which he usually knows little about except that it is bad. The exact nature of the substances called by these names and the character of the injuy caused by them are very vague in his mind; but he knows that he wants nothing to do with alkali if he can help it.

The prevalence of alkali throughout the arid parts of the world makes it impossible for …

Bulletin No 81 - The Improvement Of Pastures With Notes On The Pasture Trefoils In Western Australia, E. A. Mann, D. A. Herbert

Bulletins 1 - 2999

Agriculture can be roughly divided for practical purposes into two large divisions, those of animal husbandry and vegetable husbandry. It is with the former that this pamphlet is chiefly concerned and its object is to contribute, it possible, in some small measure towards the problem of how to increase time stock carrying capacity of our natural pasture lands. it is unnecessary to dwell upon the importance of this question, especially in relation to the remarkable developments which are taking place in time wool-growing industry in the Southern and more coastal areas of Western Australia.

Bulletin No. 170 - A Study Of Methods Of Determining Soil Alkali, D. W. Pittman

UAES Bulletins

There is a great lack of uniformity in the methods of testing soils for alkali salts and in the forms of expressing the results in a way that will show the relative toxicity of the salts. This has been pointed out by numerous investigators and has been shown to complicate the determinations so much that the results of different investigators are hardly comparable. It is of further disadvantage in that the toxic limits of an alkali as worked out by one system of analysis are often difficultly applicable to a soil that has been tested by another system. However, it …

Bulletin No. 169 - The Use Of Alkali Water For Irrigation, F. S. Harris, N. I. Butt

UAES Bulletins

Because of the scanty rainfall of arid regions, the soluble materials in the rocks and soil are not leached out as they are where the rainfall is high. As a result, the accumulation of excessive quantities of soluble salts is likely to be a menace to arid soils. Farm practices must be directed toward preventing this condition.

Bulletin No. 168 - Relative Resistance Of Various Crops Ot Alkali, F. S. Harris, D. W. Pittman

UAES Bulletins

Plants show considerable variation in their resistance to soil alkali. Some varieties of native vegetation grow only where the salt content of the soil is high. Most of the cultivated plants, on the other hand, are injured very decidedly by the presence of large quantities of soluble salts. To this rule there are a few exceptions such as the date palm.

In most of the arid parts of the world there are sections where the presence of alkali is the chief limiting factor in crop growth. Millions of acres of land are in the border zone between complete freedom from …

Circular No. 39 - A Day At The Utah Agricultural Experiment Station, M. C. Merrill, O. W. Israelsen, Byron Alder

UAES Circulars

From the days when Indian chieftains with their hostile bands roamed the sagebrush areas of Utah down to the present, nature's forces have been subdued by many a daring and successful conquest thru the intelligence and unyielding perseverance of Utah's pioneers. Since its establishment, the energies of the Agricultural Experiment Station have been directed toward a continuance of this conquest.

Circular No. 32 - Feeding Farm Animals, W. E. Carroll

UAES Circulars

Our oldest history tells us that in the beginning man was given dominion "over the cattle, and over all the earth." This was of course only potentially possible at first, and could not be realized until man developed and exercised his intelligence to this end. What, then, does it mean to have dominion over the cattle? Is this not merely to control them and direct their energies and productivity to the happiness of mankind? Surely this is so, and that man has greatest dominion who can control them most completely for the good of the race.

Relation Of Size Of Seed And Sprout Value To The Yield Of Small Grain Crops, T. A. Kiesselbach, C. A. Helm

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A superior yielding power has frequently been attributed to the extra large seed. Since the seeds of any given crop commonly differ markedly in size, it is of importance from the standpoint of crop production to know the extent to which this difference in size may affect the yield of the crop produced. The following experiments have been conducted for the purpose of contributing further to the information upon this subject.

The Production Of Alfalfa Seed In Southern Idaho, L. C. Aicher

A

The acreage given over to the production of alfalfa seed is rapidly increasing in Idaho because of the widespread interest throughout the east in growing alfalfa as a forage crop, the growing demand of eastern farmers for high-grade seed, and the higher prices obtainable since the beginning of the world war. In growing alfalfa farmers have discovered thru experience and heavy losses at times that it is more profitable to plant high-grade than inferior seed. In response to the demands of their customers and because of stringent weed laws of some states, seedsman are becoming more and more particular in …

Transpiration As A Factor In Crop Production, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of experiments reported in this bulletin has been to determine principles according to which water is used by crops. In many agricultural districts, water is frequently a seriously limiting factor in crop production. It has been thought that some means might be devised through a correct understanding of the principles involved, whereby economy in the use of water in farm practice could be increased. In this effort there are two chief points of attack, namely, (1) adjusting the external factors to the needs of the plant, and (2) selecting plants adapted to the conditions.

Circular No. 21 - Dry-Farming In Utah, F. S. Harris, A. D. Ellison

UAES Circulars

It was only a few years after the settlement of Utah in 1847 that occasional attempts were made to raise crops without the use of irrigation water, but these first attempts usually resulted in failure. Not until in the sixties could any degree of success be claimed. About this time, farmers in the valley of the Great Salt Lake and in Cache Valley began raising crops regularly on land located above the canal. From then to the present time a measure of success has been enjoyed by the better dry-farmer in some sections, and hardly a year of complete failure …

Corn Silage And Alfalfa Hay For Beef Production, Ralph K. Bliss, C. B. Lee

University of Nebraska-Lincoln Extension: Historical Materials

SUMMARY.

1. A ration of corn and alfalfa hay produced the cheapest gains of any ration used. Furthermore, the steers fed corn and alfalfa hay made as rapid gains as did the steers on any other ration.
2. Had the alfalfa hay used in the first experiment cost $20 per ton, the average profit on the three lots receiving alfalfa would have been 15 per cent greater than the profit on the best one of the three lots not receiving alfalfa.
3. Cold pressed cottonseed cake did not give as good results, as regards either rate of gain or economy …

Summary Of Two Years' Study Of Insects In Relation To Pellagra, Allan H. Jennings

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

With the growing interest in pellagra, following the authoritative recognition of its presence in the United States in 1907, the study of its etiology was taken up by various investigators and the several theories of causation were subjected to close scrutiny.

Prominent among these theories was that of insect transmission, first advanced by Sambon, who limited this function to the species of blood-sucking gnats comprising the genus Simulium.

The importance of the disease and the possibility of such a factor in its causation, led the Bureau of Entomology, late in 1911, to undertake an investigation of the subject …

Circular No. 14 - Housing Farm Poultry, Byron Alder

UAES Circulars

With the exception, perhaps, of actual starvation of the fowls themselves, there is no other factor in connection with the keeping of poultry that will affect egg production and good vigorous growth so decidedly as poor or improper methods of housing. This circular sets forth some of the essentials of a good house for Utah conditions, and offers plans of three houses in which an attempt has been made to include these essentials. The ideas and plans presented here do not represent anyone person's original work. They are a compilation of the work done on this subject by those who …
