Bulletin No. 118 - Methods For Increasing The Crop Producing Power Of Irrigation Water, John A. Widtsoe, L. A. Merrill
Bulletin No. 118 - Methods For Increasing The Crop Producing Power Of Irrigation Water, John A. Widtsoe, L. A. Merrill
UAES Bulletins
The studies of the Utah Station on the effect of water on the yields of crops have shown, first, that as the water applied increases, the total weight of dry matter also increases; and second, that the increase is not in proportion to the amount of water applied, since the less water applied, the larger the yield of dry matter for each inch of water used. These experiments, as reported in bulletins No. 116 and No. 117 indicate with much certainty the best quantities of water to use for various crops. When, however, each farmer has been allotted this best …
Bulletin No. 116 - The Production Of Dry Matter With Different Quantities Of Irrigation Water, John A. Widtsoe
Bulletin No. 116 - The Production Of Dry Matter With Different Quantities Of Irrigation Water, John A. Widtsoe
UAES Bulletins
The second period of the irrigation investigations of the Utah Experiment Station began in 1901, when plans were formulated for accurate and extensive studies of the relations to each other of soils, crops and water. Preliminary work was done on the College Farm during the summer of 1901. During the winter of 1901-02, the Greenville Farm was secured, and on it was constructed a system of weirs, flumes and laterals, whereby accurately measured quantities of water could be placed at will upon any plat. With this apparatus a great number of vital questions concerning the practice of irrigation was submitted …
Bulletin No. 117 - The Yields Of Crops With Different Quantities Of Irrigation Water, John A. Widtsoe, L. A. Merrill
Bulletin No. 117 - The Yields Of Crops With Different Quantities Of Irrigation Water, John A. Widtsoe, L. A. Merrill
UAES Bulletins
The value of an irrigated farm rests In the land and in the water available for irrigation. Usually the water right for an acre is worth considerably more than the land itself. Under irrigation it is just as important to secure the largest yield per unit of water as it is to obtain the largest yield per acre. Owing to the high cost of water, the production per unit of water is frequently more important than the yield per acre. In Utah and the other irrigated states, the water available for irrigation, or that which may be made available, is …
Bulletin No. 120 - The Chemical Composition Of Crops As Affected By Different Quantities Of Irrigation Water, John A. Widtsoe, Robert Stewart
Bulletin No. 120 - The Chemical Composition Of Crops As Affected By Different Quantities Of Irrigation Water, John A. Widtsoe, Robert Stewart
UAES Bulletins
In earlier bulletins it has been shown that when the quantity of irrigation water applied to crops is varied, the yields of the total crop as well as of the several plant parts vary quite definitely. The readiness with which plants respond to differences in irrigation is really remarkable and undoubtedly lies at the foundation of the future science of irrigation.
Variations in the quantities of irrigation water not only affect the total yield of dry matter, but also the composition of the plant itself. This fact was brought out many years ago in the investigations of this Station.
Bulletin No. 119 - The Effect Of Irrigation On The Growth And Composition Of Plants At Different Periods Of Development, John A. Widtsoe, Robert Stewart
Bulletin No. 119 - The Effect Of Irrigation On The Growth And Composition Of Plants At Different Periods Of Development, John A. Widtsoe, Robert Stewart
UAES Bulletins
Early in the pursuit of the irrigation investigations conducted by this Station, it became important to know the best amounts of water to apply at various stages of the plant's growth. The effect of the total quantity of water applied to a crop, depends in large measure upon the number of irrigations and their times of application during the season. It was thought that some light would be shed upon this problem by examining crops, under variable irrigation methods, at different times before maturity. Such work, also, it was hoped might yield more definite information concerning the manner in which …
Circular No. 7 - Labor Saving Devices For The Farm Home, Leah D. Widtsoe
Circular No. 7 - Labor Saving Devices For The Farm Home, Leah D. Widtsoe
UAES Circulars
This paper was written for and read before the first International Congress of Farm Women held at Colorado Springs, October 17th to 21st, 1911. A few changes have been made in the manuscript and some illustrations added.
The name indicates that it is written for the progressive farmers of some means--since all labor saving devices cost more or less money. The farm home which finds it difficult to keep flour in the barrel, naturally will not be interested in $125.00 water systems--except as an ideal they may attain to some day, and ideals are always helpful. To find ways and …

Bulletin No. 113 - The Influence Of The Combined Harvester On The Value Of The Wheat, Robert Stewart, C. T. Hirst
Bulletin No. 113 - The Influence Of The Combined Harvester On The Value Of The Wheat, Robert Stewart, C. T. Hirst
UAES Bulletins
The extension of the dry-farming area in Utah and the bringing of many thousands of acres of virgin land under wheat cultivation, in large farms, has, in recent years, caused much improvement in the use of farm machinery. One great improvement has been the adoption of the Combined Harvester, which cuts, threshes and sacks the grain in one operation in the field at a minimum of cost. This has been an important factor in the success of the dry-farming movement.
Bulletin No. 112 - A Report Of Seven Years' Investigation Of Dry Farming Methods, Lewis A. Merrill
Bulletin No. 112 - A Report Of Seven Years' Investigation Of Dry Farming Methods, Lewis A. Merrill
UAES Bulletins
The permanent settlement of Utah was made possible because of the introduction of irrigation methods but the growing of crops without irrigation was successfully practiced soon after the settlement of the territory. From the existing records and from the words of many of the veterans still living it is evident that many attempts were made to grow wheat in the early 50's without irrigation. Most of these attempts failed, because they were made on irrigated lands. In 1865, however, an experiment on a much more extended scale was made.

Bulletin No. 109 - The Nitrogen And Humus Problem In Dry-Land Farming, Robert Stewart
UAES Bulletins
The effect of cultivation and the growth of crops upon the nitrogen and humus content of soils has been studied by various investigators, both in America and Europe. In general, the results of the various investigations indicate that cropping and cultivation are very destructive of the organic. matter and the nitrogen of the surface soil.
Bulletin No. 108 - The Effect Of Formalin On The Vitality Of Seed Grain, Robert Stewart, John Stephens
Bulletin No. 108 - The Effect Of Formalin On The Vitality Of Seed Grain, Robert Stewart, John Stephens
UAES Bulletins
The Utah Experiment Station for a number of years has recommended the formalin treatment for the prevention of smut in wheat, oats and barley. Since the publication of Bulletin No. 84 by Prof. L. A. Merrill on the Subject, a number of complaints regarding the treatment have been received. We learned, also, by traveling over the state, that these complaints were quite general. The work reported in this bulletin was undertaken for the purpose of throwing light on these questions, and it is hoped that the results obtained will be of value to the farmers of the state.

Bulletin No. 106 - A Study Of The Production And Movement Of Nitric Nitrogen In An Irrigated Soil, Robert Stewart, J. E. Greaves
UAES Bulletins
The problem of maintaining the nitrogen content in our agricultural soils is one of vital importance to the development of a permanent system of agriculture. Any investigation, therefore, which tends to throw any light on the conditions which are necessary for maintaining the maximum supply of nitrogen in our soils needs no apology for its institution.

UAES Bulletins
The irrigation investigations conducted by the Utah Experiment Station, some of the results of which form this *report, were undertaken for the purpose of adding to our knowledge of the natural laws upon which the art of irrigation may be safely built. The work has had for its dirrect object the study of the mutual relations of plants, soils and water, as these relations may indicate the most economic use of water for plant production. In pursuit of the investigations it became necessary not only to follow the movement of water in soils under irrigation conditions, but to determine also …

Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe
UAES Bulletins
It has been found that the production of one pound of dry plant substance on soils of average fertility, requires in humid districts not more than five hundred pounds of water, and in arid districts like Utah about seven hundred and fifty pounds. This indicates that the average rainfall of Utah, which is about twelve inches, if properly conserved in the soil, is sufficient to produce annually, without irrigation, from thirty to forty-five bushels of wheat to the acre, or corresponding yields of other crops. The realization of this truth has changed greatly our views of irrigation practices. The beginning …

Bulletin No. 103 - Milling Qualities Of Meat, Robert Stewart, Joseph E. Greaves
UAES Bulletins
Investigations regarding the chemical and milling characteristics of some of the various varieties of wheat grown in the State have been carried on since the season of 1904. This is, however, the first report of the investigations that has been published. The work was started with the hope of assisting in the determination of the varieties of wheat best adapted to the State. While, of course, the variety which does not yield well but which has excellent chemical and milling characteristics is not desirable, yet on the other hand, as has already been so often pointed out, neither is the …

Bulletin No. 101 - Feeding Experiments With Cattle, Sheep, Swine And Horses, R. W. Clark
UAES Bulletins
Since the establishment of sugar factories in this State, considerable inquiry has arisen regarding the food value of sugar beets and the by-products of the factories. The last publication from this station on the subject was Bulletin No. 90 which gave the results of feeding sugar beet pulp and molasses in various combinations to sheep and steers. Previous to the appearing of this publication some experimental work had been carried out in feeding sugar beets to swine and sugar beet pulp and beet molasses to sheep. The results secured seemed to warrant further work in the same direction and in …

The Utah Legislature of 1903 passed a bill providing for the investigation by the Experiment Station of dry-land farming problems in the State of Utah, and appropriating $12,500 to be expended in carrying on this work during the two years, 1903 and 1904. Six experimental dry farms were located one in each of the following counties: Iron, Juab, San Juan, Sevier, Tooele and Washington. A second appropriation of $15,500 was made by the Legislature of 1905, for the purpose of continuing, the investigations.

A general plan for the scientific investigation of the laws governing plant production as influenced by the application of irrigation water, was outlined in 1900 by Dr. John A. Widtsoe as Director of the Utah Experiment Station. The detailed plans were prepared by the heads of the Chemical, Agronomy and Irrigation Department, under whose cooperation the work was to be carried on. In 1903 the Office of Experiment Stations of the U. S. Department of Agriculture, by contributing funds to this work, became a party to the experiments. Since then the investigations have been under the joint supervision of the …

UAES Bulletins
The codling moth continues to be the most s serious pest of the Utah horticulturist and was therefore made the main subject of investigation by the Entomological Department for the season of 1904.
In spite of the immense amount of work that ha been done on this subject by various entomologists in this and other countries, several vital points still remain unknown and many more that have been worked out for other localities must be verified and adapted to our conditions.

UAES Bulletins
The present high position of Utah among the great commonwealths is due to the practice of irrigation. According to the last census, about 983 square miles are now being irrigated; and yet only a small fraction of Utah's water supply is used for purposes of irrigation. With the adoption of improved methods of using water, and the construction of mighty reservoirs to store the floods of spring, the irrigated area in this State will be largely increased. It is not at all improbable that in time the water supply may be made to irrigate ten times the area now under …

The codling moth has been in the State of Utah for over twenty-five years and is now injuriously abundant in every apple-growing section. It is by far the worst pest with which the fruit grower has to contend. In fact, it usually does more damage than all the other fruit insects put together.
It occurs throughout every apple-growing region of the United States, and is found in almost every country where the apple is grown, destroying from one-fourth to three-fourths of the apple crop where no effort is made to check its ravages. Dr. Howard the United States Entomologist, recently …

Farmers are urged to treat all their seed grain with Formalin, during the coming spring, and thus save to the state, next year, thousands of dollars now lost by smut-infested grain.
Formalin can be purchased at any drug store for about seventy-five cents per pound. Pour one pound of Formalin in fifty gallons of water and completely submerge the seed grain, which is loosely held in burlap sacks, for ten minutes. Dry the seed and it is ready for use.
