Circular No. 17 - The Number And Distribution Of Licensed Stallions And Jacks In The State In 1913, W. E. Carroll

UAES Circulars

Table No. 1 shows the number of licensed stallions and jacks of each breed in each county of the State. It will be seen that 439 licenses have been issued. Of these 92 are grades, which means that 79 per cent of all the licensed animals of the State are purebred. Cache County leads with 59 licensed animals, including 8 grades. Sevier County stands second with 51, including 8 grade animals. Sanpete County has 43 licensed animals, including 10 grades. Utah County has 44, two of which are grades. The number of licensed animals vary in the other counties from …

Circular No. 16 - Better Seed, Frank S. Harris

UAES Circulars

It is impossible to produce good crops unless good seed is used. The soil may be of the best quality and it may be prepared in the most thorough manner, the supply of moisture may be ample, the season may be the most favorable, yet all these count for little if worthless seed is planted.

Bulletin No. 131 - Variety Tests Of Field Crops In Utah, Frank S. Harris, J. C. Hogenson

UAES Bulletins

The number of varieties of practically all the field crops is now very great, and is increasing every year. Each variety has certain growers who believe in it and who do what they can to make it more widely grown. As a result many varieties of crops are found in most every farming community.

This condition is often bad, since it is impossible to build up a good market with a great mixture of varieties of any crop. A much better price can be obtained if each community offers for sale large quantities of a few standard types, rather than …

Bulletin No. 132 - Minor Dry Land Crops At The Nephi Experiment Farm, P. V. Cardon

UAES Bulletins

The investigations conducted at the Nephi substation deal primarily with cereals; other crops, such as alfalfa, peas, corn, potatoes, etc., have occupied only a secondary position in the work of this station. This necessarily has been true because the experiments are confined to dry-land practices, and the cereals unquestionably comprise the basal crops for dry-land farming as it is now understood and practiced in Utah. No crops have been found as yet which yield so profitably on the dry lands as do the cereals, especially winter varieties.

The purpose of this bulletin is to review the work done on the …

The Inheritance Of A Recurring Somatic Variation In Variegated Ears Of Maize, R. A. Emerson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The inheritance of variegation has special interest and importance in genetics. In this paper I shall present data from maize and attempt to show how they can be interpreted in strictly Mendelian terms.

Bulletin No. 130 - The Change In Weight Of Grain In Arid Regions During Storage, Frank S. Harris, George Thomas

UAES Bulletins

In handling grain the question of the changes that may occur in weight after threshing is always before the dealer. If there is any considerable loss during storage his profits are consumed, while if there is a gain it is possible for him to work on a much closer margin.

The Inheritance Of A Recurring Somatic Variation In Variegated Ears Of Maize, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

The inheritance of variegation has special interest and importance in genetics. It is with forms of variegation that the only two certainly known cases of non-Mendelian inheritance have had to do. I refer to Baur's experiments with Pelargonium, in which crosses of green-leaved and white-leaved forms exhibited somatic segregations in F₁ that bred true in later generations, and to Correns 's work with Mirabilis, which showed green and white leaf color, to be inherited through the mother only. De Vries's con- ception of "ever-sporting" varieties was apparently founded largely upon the behavior of variegated flowers in pedigree …

Rocky Mountain Flowers, Frederic E. Clements, Edith Schwartz Clements

School of Biological Sciences: Faculty Publications

AN ILLUSTRATED GUIDE FOR PLANT-LOVERS AND PLANT-USERS WITH TWENTY-FIVE PLATES IN COLOR AND TWENTY-TWO PLATES IN BLACK AND WHITE

The present book is an endeavor to present the materials of the Rocky Mountain flora in preliminary form from the standpoint of the experimental ecologist. The latter is concerned primarily with the relationships of "species" and their subdivisions as an organic expression or measure of habitat differences, and of the competitive relations of the various formations. Whatever the taxonomic value of the numerous segregates of the last decade or two, the fact that the binomial form conceals the relationship to the …

Multiple Factors Vs. "Golden Mean" In Size Inheritance, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Groth's preliminary note on the "golden mean" in the inheritance of sizes in SCIENCE of April 17, 1914, pp. 581-584, deserves the attention of geneticists. Its publication is of such recent date that I need only call attention to one or two points that seem to me of particular moment.

In brief, Groth's hypothesis is that the mode

of inheritance in F_l not only of surfaces and

volumes, but also of linear dimensions is to be

expressed by √ab rather than by a + b /2

where a and b are parent sizes. The hypothesis

is based upon …

Bulletin No. 128 - Blooming Periods And Yields Of Fruit In Relation To Minimum Temperatures, A. B. Ballantyne

UAES Bulletins

As noted In Bulletin 124, the Southern Utah Experiment Farm is located in Washington Field, southeast of St. George. This tract of land is comparatively low and flat and bounded on three sides by hills. On the front or north side it extends to the Rio Virgin river, which enters and leaves the valley through small canyons. This entire area has a very poor water and air drainage. Frosts occur here much more severely and much later than on the surrounding bench land.

Bulletin No. 129 - Codling Moth Studies In 1911: The Driving Spray Under Excessively Wormy Conditions, E. D. Ball, W. M. Ball

UAES Bulletins

Spraying experiments against the codling moth were carried on upon the Smart orchard until the number of worms per tree was reduced to such an extent that no accurate comparisons could be made between different treatments. As a result of the work on this and other orchards, practically every commercial orchard in the valley was by this time well sprayed and the worms reduced to a point where one driving spray per season would keep them under control.

In the meantime a number of questions arose which required very wormy conditions to adequately investigate. Search was therefore made for orchards …

Circular No. 15 - Pastures And Pasture Grasses For Utah, F. S. Harris

UAES Circulars

Since the earliest records of man his domestic animals have secured a large proportion of their forage from pastures. Before crops were planted and harvested by man the wild grasses furnished the chief food for numerous kinds of animals, and the cutting and curing of hay came as a later development to supplement natural pasturage in seasons of scarcity.

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 …

Bulletin No. 123 - Farm Drainage: A Manual Of Instruction, Chas F. Brown

UAES Bulletins

In addition to emphasizing the general need for drainage in the arid regions with reference to seepage and alkali problems, this bulletin is intended as a practical treatise covering all engineering phases of farm drainage, from the general observations concerning specific needs of drainage, to the realizations of successful reclamation. It is made up of two parts for convenience in handling and distribution, Part I, Manual of General Instruction, and Part II, Practical Discussion of Problems.

Bulletin No. 126 - A Comparison Of First, Second And Third Crop Alfalfa Hay For Milk Production, W. E. Carroll

UAES Bulletins

In most sections of the State three crops of alfalfa hay are harvested. There is a widespread opinion among practical feeders in this locality that these crops of hay are not of equal value for feeding purposes. Especially is this true when feeding dairy cows is considered. The belief is so strong in some cases that farmers have said they would exchange three tons of second crop hay for two of first crop when feeding milk cows. Third crop hay is given second choice.

Bulletin No. 125 - The Chemical Milling And Bake Value Of Utah Wheats, Robert Stewart, C. T. Hirst

UAES Bulletins

The Chemical Department of the Utah Experiment Station, since 1903, has been conducting investigations regarding the value of different wheats grown in the State. The results obtained during the years 1903 to 1906 were published as Bulletin No. 103 of this station. A special investigation in 1910 regarding the influence of the combined harvester on the value of the wheat was conducted and the results obtained issued as Bulletin No. 113. The results reported in the following pages were obtained during the progress of these investigations during the years 1907, 1908, and 1909. The method of milling the samples of …

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 …

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 …

Circular No. 10 - The Control Of The Alfalfa Weevil, E. G. Titus

UAES Circulars

During the work with the alfalfa \weevil throughout several very different seasons and in different regions, of the State, a number of methods of control have been developed that bid fair to be of service in combating this insect. The prospect for the alfalfa grower in the infested area looks more hopeful each year. It is the purpose of this circular to give a brief account of the alfalfa weevil, its present distribution, and the principal methods that appear to be of value in its control.

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.

Circular No. 13 - Fruit For Exhibition, Leon D. Batchelor

UAES Circulars

The basis of a good fruit exhibit is necessarily good cultural conditions to produce good fruit. Then it depends on the exhibitor's ability to select his best fruit. Do not wait until the crop is picked to select show specimens. The successful exhibitor makes his prize selections in the orchard while the fruit i still on the tree. By viewing the fruit as it hangs naturally on the tree, and by carefully surveying the different trees in the orchard a good comparison of a large quantity of fruit can be made. The prize fruit is generally on the outermost branches, …

Shorter Articles And Discussion Simplified Mendelian Formulae, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

I was somewhat surprised by 'Morgan's and Castle's suggestions for a simplification of Mendelian formulae. My surprise was not occasioned so much by the forms these suggestions took as by the fact that any pronounced changes were deemed necessary. I had not only employed the usual formula in my own work but had found no difficulty worth mentioning in understanding the formula used by most other workers in Mendelian fields. My experience with students in elementary courses in genetics had not prepared me for the idea that such formula were particularly difficult. Nevertheless I believe in simplifying the formulae if …

The Possible Origin Of Mutations In Somatic Cells, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

That mutations are accompanied by some change in the germ-plasm is, I take it, indisputable. Have we, however, any reason to suppose that the change takes place within the germ cells? I am not sure, as a matter of fact, that genetists in general regard the gametes as the place of origin of mutations. It is true, however, that experiments in the artificial production of mutations in plants have been limited largely to treatments of the ovaries from about the time of the reduction division to about the time of fertilization. This suggests a belief on the part of investigators …

Shorter Articles And Reports: The Simultaneous Modification Of Distinct Mendelian Factors, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

In another paper on the inheritance of a recurring somatic variation in variegated ears of maize, it was shown that the amount of red color developed in the pericarp of variegated seeds bears a definite relation to the development of color in the progeny of such seeds. The relation is such that the more color there is in the pericarp of the seeds planted the more likely are they to produce plants with wholly self-red ears and correspondingly the less likely to produce plants with variegated ears. Self-red ears thus produced behave just as if they were hybrids between self-red …

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 …
