Circular No. 30 - The Codling Moth (Carpocapsa Pomonella L.), Harold R. Hagan

UAES Circulars

The Utah Experiment Station bulletins originally published, outlining satisfactory methods for reducing injury by the codling moth, are no longer available for distribution. This circular. contains in briefer form the essential information for controlling the pest.

Circular No. 29 - The Control Of Rodent Pests: Directions For Killing Ground Squirrels, Pocket Gophers, Rabbits, And Field Mice, Charles J. Sorenson

UAES Circulars

Rodent pests cause heavy damage to the crops of Utah. The four most destructive of these pests are ground squirrels, pocket gophers, rabbits, and field mice.

The most effective method for the destruction of these animal pests is the use of poisoned baits. A very important factor in their control is the natural enemies.

The formulae recommended in the following pages have been, and are now being, used with excellent success in this and neighboring states.

Circular No. 28 - Contagious Abortion In Mares And Cows, H. J. Frederick

UAES Circulars

Contagious abortion is a cause of great loss to the stock growers of Utah. There is an urgent demand from nearly all parts of this State for information relative to this disease. In an effort to satisfy this demand a few facts regarding the disease as they are now known are here presented. It is not the purpose of this circular to report original research, but merely to describe the disease as it exists among animals in this State. The causes, symptoms, diagnosis, and methods of combating and controlling this great menace to the livestock industry are all considered.

Circular No. 26 - Storing Vegetables For Winter, M. C. Merrill

UAES Circulars

The storing of vegetables for winter use has come to be important. The joys of having a large variety of choice garden produce available for the table at any time are no longer confined to growing season. Because we are thrifty today and plan for the morrow, we gather our crops in the fall and store them for winter use.

In spite of its importance, comparatively little research work has been done on the problems of storage. AS a result we are still employing many of the same methods that were devised by our forefathers, except in the case of …

Bulletin No. 161 - Orchard Heating, Frank L. West, N. E. Edlefsen

UAES Bulletins

In the state of Utah scarcely a year passes without some damage being done to farm crops, either in the spring or the fall, because of the occurrence of killing frosts. For example, in the spring of 1916 the tops of the young beets were frozen, about one-fourth of the grain of the northern part of the state was frozen, the yield of the first crop of alfalfa was about half normal and 90 per cent of the fruit of the state was destroyed. During the month when fruit buds are in bloom, the report of the U. S. Weather …

Bulletin No. 160 - Important Factors In The Operation Of Irrigated Utah Farms, E. B. Brossard

UAES Bulletins

Two agricultural problems that are fundamental and of prime importance to the people of Utah are:

1. The development to maximum economic agricultural production of those farms now operated.

2. The agricultural development of the many thousands of acres of new land in the state.

A realization of the importance of these problems caused this investigation to be made. The purpose of it is as follows :

1. To determine what has been the experience of practical farmers, relative to the most profitable systems of farm management on irrigated Utah farms, and to suggest profitable future development of the existing …

Bulletin No. 158 - Soil Moisture Studies Under Dry-Farming, F. S. Harris, J. W. Jones

UAES Bulletins

Profitable cultivation of land under dry-farm conditions is dependent on the efficient use of precipitation. Soil fertility is not at present the limiting factor in crop production on most arid lands, but insufficient moisture to make available the fertility of these dry-lands is not only a limiting factor, but in most cases the controlling factor in crop production. The rainfall in the principal dry-farming areas of Utah varies from 12 to 15 inches a year. During different years it may range from 10 to 22 inches; therefore the best use must be made of the water that falls.

Bulletin No. 159 - Soil Moisture Studies Under Irrigation, F. S. Harris, A. F. Brakcen

UAES Bulletins

Under normal precipitation the variety of crops which can be successfully grown in the West is limited. Of necessity, irrigation was practised and with it came many complex problems. The water requirements of different crops, the water-holding capacity of soils, the movement of soil moisture, and numerous other related problems have given themselves up for investigational work.

Bulletin No. 157 - The Irrigation Of Potatoes, F. S. Harris

UAES Bulletins

Very few field crops yield as large returns to the acre as do potatoes during favorable years, and but few crops are as greatly affected in quality and yield by soil and seasonal conditions. The potato is particularly sensitive to soil moisture. For this reason yields under irrigation, where the moisture can be controlled, are usually much higher than where the moisture supply is irregular.

Bulletin No. 155 - The Beet Leafhopper And The Curly-Leaf Disease That It Transmits, E. D. Ball

UAES Bulletins

The beet leafhopper (Eutettix tenella Baker), is the most serious pest of the western sugar beet. It has through the disease it tranmits caused periodic losses to the western sugarbeet industry, amounting in the aggregate to many millions of dollars. Curly-leaf, the disease which this insect transmits, has in some of its worst outbreaks caused the abandonment of thousands of acres of beets in certain districts and a serious reduction in tonnage of the remainder, so that the total loss in a single area has several times passed the million-dollar mark. Besides these striking and widespread outbreaks which fortunately have …

Bulletin No. 156 - The Irrigation Of Sugar Beets, F. S. Harris

UAES Bulletins

The sugar beet crop during the last few years has come to be one of the most important sources of income for farmers in many sections of the country. The fact that the sale for the crop is certain at a price that is known in advance, in addition to the high type of farming that usually accompanies sugar beet raising, makes it probable that the sugar beet area will be considerably extended during the next few years.

Bulletin No. 150 - Further Studies Of The Nitric Nitrogen Content Of The Country Rock, Robert Stewart, William Peterson

UAES Bulletins

The progress of the work upon the general problem of the origin of the nitre spots in certain western soils has presented several different points of view. The fact that certain spots in western cultivated soils were rich in nitrates was first observed by Hilgard who attributed their accumulation to the more rapid nitrification of the organic matter of the soil in the warm arid climate of the west when the moisture limit was removed by irrigation.

Bulletin No. 153 - Selecting Dairy Bulls By Performance, W. E. Carroll

UAES Bulletins

Success in any system of breeding requires that each generation approach more nearly the object in view than has all preceding generations. Such progress is possible only when proper judgment is exercised and the best methods employed. In cattle breeding, for economic reasons, the bull is usually expected to contribute more to this general improvement than is the cow. To make this possible, the bull must therefore have been subjected to more rigid selection than the cow in order to eliminate more of his undesirable characters. If he contains few undesirable characters, from the breeding standpoint, he must of necessity …

Circular No. 25 - Preserving Eggs For The Home, Byron Alder

UAES Circulars

The preserving of eggs in the home from the spring when they are so plentiful until fall and winter when they are so scarce, is by no means a new practice. Only a very few, however, are taking advantage of this practice and the full benefits are by no means being derived. During the past winter the high cost of eggs has brought this fact out very forcibly in some of the rural districts as well as in the larger cities where the price for a considerable time was from 50 to 60 cents a dozen and only a limited …

Bulletin No. 154 - Irrigation And Manuring Studies Ii: The Effect Of Varying Quantities Of Irrigation Water And Manure On The Growth And Yield Of Corn, F. S. Harris, D. W. Pittman

UAES Bulletins

The present bulletin describes the results of an experiment on the irrigation and manuring of corn for the six years from 1911 to 1916, inclusive. The first three years' results of this experiment have already been published as Bulletin No. 133 of this Station. Besides the material discussed in that publication the present bulletin contains data on the composition of corn here presented for the first time.

Circular No. 24 - Licensed Stallions In Utah During The Season Of 1916, W. E. Carroll

UAES Circulars

The State Board of Horse Commissioners, during the season of 1916, was able to cover the State more thoroughly than has ever been possible before. Because of this greater activity and more complete canvass the number of licensed stallions and jacks in this report is greater than before. During the season of 1916 there were in force 420 licenses a against 289 for 1915.

Bulletin No. 151 - The Freezing Of Fruit Buds, F. L. West, N. E. Edlefsen

UAES Bulletins

There are many orchards in this country, so located that every few years a frost almost completely destroys the crop, either by killing the buds in the spring of the year, or by freezing the fruit in the fall, just before it is picked. Utah is no exception. A report made by the county agricultural agents of the state, shows that in the spring of 1916, 85 percent of the apples, 90 percent of the peaches, and 65 percent of the mall fruit were killed by frost with a corresponding amount of damage to field crops.

Bulletin No. 152 - The Effects Of Soil Moisture Content On Certain Factors In Wheat Production, F. S. Harris, Howard J. Maughan

UAES Bulletins

A knowledge of the intimate relations between the crop and the moisture of the soil is important to every farmer, and particularly to those in the arid parts of the world. While wheat is not an intensive crop and probably will not give as great returns to the acre for extra care as some other crops, it is well worth while to know how this crop responds to various treatments. The effect of high and low soil moisture during various stages in the growth of the crop is of particular interest. The work of other experimenters on this subject has …

Bulletin No. 149 - Breeding For Egg Production, Part Ii: Seasonal Distribution Of Egg Production With Especial Reference To "Winter" Egg Production, E. D. Ball, Byron Alder

UAES Bulletins

In this bulletin will be found a discussion of the seasonal distribution of egg production during first, second, and third, and later years of egg-laying of the same flocks of hens and a comparison of the distribution of production of high-laying and low-laying flocks in the same season, and different seasons as well as high-laying and low-laying individuals of the same flocks. These studies are based on six flocks of White Leghorn hens ranging from nine years to three years old and all descendants of a common flock. The methods of handling, feeding, and other details are discussed in previous …

Genetical Studies Of Variegated Pericarp In Maize, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Two years ago there were presented some results of a study of the inheritance of self pattern in the pericarp of maize seeds, occurring as a sporophytic2 variation in variegated ears (EMERSON1 914). Further results, in entire accord with those previously reported, have now been obtained. In addition, data bearing upon new phases of the problem are also available.

The chief results reported in the earlier paper were the following: ( I ) The more nearly self-colored the pericarp of any seed of a variegated ear, the more likely is the progeny of that seed to produce a self-colored ear …

Circular No. 23 - The Seed Situation In Utah, George Stewart

UAES Circulars

Due to the use of poor seed, the farmers of Utah lose yearly many thousands of dollars. Often single farms suffer to the extent of several hundred dollars. The most regretable and yet the most hopeful thing about the seed situation is that these losses are largely preventable.

Abundant area of unoccupied public lands have hitherto been within the reach of practically any wide-awake tiller of the soil. The farmer was more nearly sure of larger hay tacks and more bushels of grain or potatoes if he doubled the size of his fields than if he attempted more thorough cultivation. …

Bulletin No. 148 - Breeding For Egg Production: Part 1, A Study Of Annual And Total Production, E. D. Ball, Byron Alder, A. D. Egbert

UAES Bulletins

The average annual egg production of different breeds of fowls, the production that may be expected under different environmental conditions, the average length of life, the total probable production of an individual and the distribution of this production through the life cycle, are all subjects of vital importance to every poultryman. They are also subjects upon which there must be reliable information before accurate breeding work can be carried on. A search through the literature shows that information on all these subjects is extremely meagre.

Circular No. 22 - Some Sources Of Potassium, C. T. Hirst, E. G. Carter

UAES Circulars

The essential elements of plant food are ten in number. Of these carbon and oxygen are obtained by the plant from the air, and hydrogen from the water. Sulphur, calcium, iron and magnesium are required by plants in small quantities and are not likely to be deficient in soils. The three remaining ones--nitrogen, phosphorus, and potassium--are likely to be present in soils in smaller quantities and are used by plants in larger amounts than any of the other elements taken from the soil. In addition to these ten elements already named, five other elements, viz., silicon, aluminum, sodium, chlorine, and …

Bulletin No. 146 - The Irrigation Of Wheat, F. S. Harris

UAES Bulletins

The economical use of irrigation water is one of the chief problem of agriculture in arid region. Much more land is available than can be irrigated by the supply of water even then methods of greatest economy are employed. The total crop of arid regions is therefore limited not by land but by water and the welfare of the regions demand that the irrigation water be used as efficiently as possible.

Bulletin No. 145 - Soil Alkali Studies: Quantities Of Alkali Salts Which Prohibit The Growth Of Crops In Certain Utah Soils, F. S. Harris

UAES Bulletins

One of the most important questions connected with the alkali problem in arid soils is the determination of the limits of toxicity of the various alkali salts. The author has already presented considerable data on this subject; but most of these results were obtained under laboratory conditions and with the use of pure salts. The combinations of salts used were not necessarily the combinations found in actual field conditions. It seemed desirable, therefore, to extend these studies to the field in order to determine the exact concentration of the various alkalis that prohibits growth in crops. A study of this …

Bulletin No. 147 - The Alkali Content Of Irrigation Water, Robert Stewart, C. T. Hirst

UAES Bulletins

In certain irrigated districts the alkali problem is a menace. Any controllable factor which tends to increase the alkali content of the soil should be carefully considered in a successful system of soil management. In this connection the quality of the irrigation water is of great importance; the saline content of water has a marked influence upon the method and quantity to be used for irrigation. The factors which will contribute to an increase or decrease of the alkali content of the water must be clearly understood. The amount of the several kinds of alkali salts added to the soil …

Bulletin No. 144 - Water Table Variations: Causes And Effects, A. B. Ballantyne

UAES Bulletins

No abstract provided.

Bulletin No. 143 - Fruit Tree Root Systems: Spread And Depth, A. B. Ballantyne

UAES Bulletins

As mentioned in Utah Station Bulletin No. 124, seepage conditions on the Southern Utah Experiment Farm were responsible for the removal of about 5 acres of vineyard in 1908, and 7 acres of mixed peach orchard in 1910, all of which were on the lower or western half of the farm.

These orchards and vineyards had always received good care, clean culture being practiced in fact as well as name. The results for a number of years were all that could be desired, when the trees and vines began to die questions arose as to the cause: since in spite …

Circular No. 20 - Capsule Method Of Breeding Mares, W. E. Carroll, J. Frederick

UAES Circulars

Some inquiry has been received by the State Board of Horse Commissioners relative to the capsule method of breeding mare. With the thought that a brief statement of the instruments used and the methods employed in the so-called capsule method of breeding might be useful to stallion men in general, this little circular has been prepared.

Circular No. 19 - Licensed Stallions In Utah During The Season Of 1915, W. E. Carroll

UAES Circulars

In presenting this report of the State Board of Horse Commissioners, it is thought best to include very little which does not bear directly upon the number and distribution of licensed stallions and jacks. Other material treating different phases of the horse industry appears in other circulars from the Board.
