Bulletin No. 124 - Fruit Variety Tests On The Southern Utah Experiment Farm, A. B. Ballantyne

UAES Bulletins

Since the material contained in the following report of the variety tests on the Southern Utah Experiment Farm was mainly accumulated under plans outlined before the farm was made part of the Utah Experiment Station, it may be well in this connection to give a brief history of its location, management, and a survey of its situation. It was established by an act of the State Legislature approved March 21, 1899, and the site was chosen the following July by a committee appointed by Governor Heber M. Wells. The area selected consists of forty acres located in the southeastern portion …

Bulletin No. 127 - Report Of The Richmond-Lewiston Cow Testing Association, W. E. Carroll

UAES Bulletins

The function of all domestic animals is to utilize the coarse rough reeds and transform them into something useful to mankind, either food, clothing, or energy. The animal thus acts as a concentrator for low grade ores, so to speak. The class of animals which will produce most human food, clothing, or energy for man from a given amount of feel--other cost being equal--is the most economical and the one which will remain longest with us as population becomes more dense and the question of food supply becomes keener.

Experiments have shown the dairy cow to be probably the most …

Alfalfa Inoculation Tests, C. W. Pugsley

University of Nebraska Historical Extension: Bulletin

During the winter of 1909-10 an effort was made to secure cooperators among the farmers of Nebraska to test the value of inoculating newly seeded alfalfa fields. This investigation was 8uggested by reports received from correspondents during 1909. The names of farmers willing to cooperate were secured by correspondence and by conferences at the various Short Courses held during that year.

In the spring of 1910 about thirty-five farmers, located largely near Broken Bow, Cambridge, Franklin, and Blair, agreed to test the effect of cultures sent by the United States Department of Agriculture, soil from well-established alfalfa fields, and farm …

The Inheritance Of Quantitative Characters In Maize, R. A. Emerson, E. M. East

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The experiments conducted by one of the writers were begun at the Connecticut Agricultural Experiment Station at New Haven in 1906 and removed to the Bussey Institution of Harvard University at Forest Hills, Massachusetts, in 1909. The materials employed in this study consisted principally of crosses of Tom Thumb pop with Black Mexican sweet and of Watson flint with Leaming dent. The number of rows per ear were noted in several other crosses, the parents of which are listed later in this paper. The experiments of the other writer were begun at the Nebraska Agricultural Experiment Station at Lincoln in …

A Dry Rot Of The Irish Potato Tuber, E. Mead Wilcox, George K.K. Link, Venus W. Pool

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The first specimens of the dry rot herein described were received by the department of Agricultural Botany during the winter of 1907-1908 from western Nebraska. A preliminary survey of the situation showed clearly the importance of this new rot, and an exhaustive investigation of the disease was outlined and has been continued to the present time. The present publication gives the results secured to date in our investigation of this disease.

Some Of The Next Steps In Botanical Science, Charles E. Bessey

School of Biological Sciences: Faculty Publications

When one who has worked long in any

field of science speaks before an audience

such as this he is expected to say something

about the condition of his branch of science

when he began work with meager and

poorly adapted apparatus, to contrast it

with its greatly improved condition to-day,

and to dwell with pride upon the finely

equipped laboratories with costly apparatus

especially designed for particular

experiments, to be found by the twentieth

century scientific student. And 1 must

confess that the temptation to do so was

one difficult to resist, for we who have

grown old in …

Two Lincoln (Nebraska) Typhoid Fever Epidemics Of 1911 And 1912., Herbert H. Waite

School of Biological Sciences: Faculty Publications

On August 29, 1912, I was requested by the Board of Health of the city of Lincoln to make an investigation to determine if possible the origin and cause of an outbreak of a disease reported as typhoid fever which was then prevailing. This outbreak was said to be most prevalent in one particular portion of the city and consequently attention was turned to that portion. Of the cases reported an investigation was made of over 60 individuals and after considering all the probable causes for the majority of those affected the conclusion was reached that all could be logically …

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. 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

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. 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 …

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 …

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 …

Circular No. 6 - Measurement And Distribution Of Irrigation Water, L. M. Winsor

UAES Circulars

This circular has been prepared to meet the more urgent and immediate needs of the water user. The complications which usually arise in water measurement have been eliminated to such an extent that anyone who will follow the few simple instructions outlined in the following pages can learn to measure the flow of irrigation streams under ordinary conditions.

A Classification For Forestry Literature, Faculty Of The Yale Forest School

Yale School of the Environment Bulletin Series

The following classification for forestry literature has been prepared by the Faculty of the Yale Forest School for use in its library. It is published to supply the demand for a simple and comprehensive classification that is adapted to any library system. The work was begun about one year ago and included a study of all available data on the subject. A tentative outline was submitted to prominent members of the profession from whom helpful suggestions were received.

The subject has been divided into nine parts of approximately equal importance. The secondary divisions also have been limited to nine and …

Circular No. 5 - Boys' Potato Clubs: How To Grow The Crop And Organization, J. C. Hogenson

UAES Circulars

The object of the organization is to encourage, interest and instruct its members in agriculture, and particularly in the best methods of growing potatoes. "Efficiency" is the motto of the clubs. Efficiency in any good work is true and profitable education. To do good things intelligently and with cheerful spirit entitles the member to the highest degree of approval.

Spraying As An Essential Part Of Profitable Apple Orcharding, R. A. Emerson, R. F. Howard, V. V. Westgate

University of Nebraska Historical Extension: Bulletin

It was therefore planned from the start not merely to demonstrate the possibility of controlling apple insects and diseases but also to determine whether they could be controlled profitably. To accomplish this it was necessary to know: exactly what it cost to spray, what sprayed fruit yielded, and what it was worth in comparison with unsprayed fruit from the same orchards. In every spraying demonstration the time spent in mixing and applying the materials and the quantity of material used were recorded. The cost of labor of men and teams per hour was taken at the orchard owners' estimates and …

New Elementary Agriculture, Charles E. Bessey, Lawrence Bruner, Goodwin D. Swezey

School of Biological Sciences: Faculty Publications

This is an agricultural nation. The products of the soil are the basis of her industries and her prosperity. The children of our great Commonwealths should be familiar with our crops, our grains and grasses, our flowers and fruits, our trees and shrubs and weeds, our domestic animals and birds and insects. Our children should have a practical knowledge of the management of a farm, of the composition of the soil, and of the adaptability of the farm and its soil for the cultivation of certain plants and the counter effect of such plant growth upon the soil. They should …

Botanical Teaching, Charles E. Bessey

School of Biological Sciences: Faculty Publications

Some months ago a suggestion was made that at this dinner we should ask ourselves the question: Why is it that with the enormous classes we are having in botany there is a marked dearth of properly trained men who can serve as instructors in colleges and universities?

Discussion And Correspondence Coupling Vs. Random Segregation, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

To the editor of science: The suggestion offered by Morgan, in SCIENCE of September 22, to account for the coupling and repulsion of factors for various characters in inheritance in such forms as Abraxas, Drosophila, fowls, sweet peas, etc., incites this note.

Briefly Morgan's hypothesis is (1) that the materials representing factors that couple are "near together in a linear series" in the chromosomes; (2) that, when pairs of parental chromosomes conjugate, "like regions stand opposed "; (3) that "homologous chromosomes twist around each other," but that the separation of chromosomes is in a single "plane"; (4) that, thereby the …

Bulletin No. 111 - The Reclamation Of Seeped And Alkali Lands, C. F. Brown, R. A. Hart

UAES Bulletins

In the year 1905, Drainage Investigations were begun in the State of Utah by the Office of Experiment Stations of the United States Department of Agriculture, in co-operation with the Utah Experiment Station. Appropriations have been made by the Utah State Legislature for irrigation and drainage investigations on condition that the United 8tates Department of Agriculture contribute an equal amount, and that the work be conducted jointly by the Federal department and the experiment station of the Agricultural College of Utah.

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

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. 110 - The Alfalfa Leaf-Weevil, E. G. Titus

UAES Bulletins

The alfalfa leaf-weevil (Phytonomus murinus Fab.) which has during the last three years been doing considerable damage in the central part of this State, is a European insect which by some means unknown has been introduced in to Utah. The species appears to be not uncommon throughout Europe and parts of Asia and Africa. It belongs to the large order of hard-shelled insects called beetles (Coleoptera) and in a group generally called snout-beetles (Family Curculionidae). To this same group belong many of our most serious pests, such as the plum curculio, cotton boll-weevil and strawberry weevil.

It occurs over all …

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. 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.

Bulletin No. 107 - Improvement Of Utah Horses, John T. Caine Iii, H. J. Frederick

UAES Bulletins

Horse breeding in Utah, with some exceptions, has been carried on in a hap-hazard manner, and unsound horses of doubtful breeding have been purchased at high prices and have proven of little value. Where good blood has been introduced the temporary improvement has been marked, but as this work has not been followed up with care, results have not been lasting.

In spite of bad breeding, however, the standard of Utah horses has been advancing so that in western markets they command high pries. The climate, soil, feed and general conditions throughout the state make it an ideal place for …

Bulletin No. 105 - Factors Influencing Evaporation And Transpiration, John A. Widtsoe

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 …
