Bulletin No. 243 - Distribution And Damage By Jointwork Flies In Utah, G. F. Knowlton, Melvin J. Janes Jul 1933

Bulletin No. 243 - Distribution And Damage By Jointwork Flies In Utah, G. F. Knowlton, Melvin J. Janes

UAES Bulletins

The purpose of this investigation has been to determine the distribution and extent of injury of some of the more important jointworm flies attacking small grains. These obscure enemies exact a yearly toll by causing a subtle shrinkage in the weight and a decrease in quality of grain yields and, incidentally, a shrinkage in the profits derived from the farmer's labors, In general, jointworm flies may be controlled by simple, previously-known methods of improved farm practices, requiring no additional outlay in cash but a better timing and proper execution of good farm practices.


Bulletin No. 241 - Peach Harvesting Studies, F. M. Coe Apr 1933

Bulletin No. 241 - Peach Harvesting Studies, F. M. Coe

UAES Bulletins

The purpose of the four seasons' study of maturity indexes of Elberta type peaches, made in Utah during the years 1926, 1928, 1929, and 1932 and presented in this publication, was to determine more accurately the best stage of maturity of peaches for distant shipment. In general, the procedure was: (1) To record color, pressure test, and other maturity indexes of fruit from trees under various conditions of culture, age, and vigor; (2) to classify the fruit by size and ground color; (3) to store under conditions comparable to refrigerated shipment to market; and (4) to record the appearance, quality, …

UAES Bulletins

Fleeces from range-bred ewes wintered on desert ranges are compared in this bulletin with fleeces taken from ewes of the same breeding wintered under farm conditions, involving regular feeding, shelter, and free access to water. Four hundred and sixty-two fleeces are included in the comparison.


Bulletin No. 238 - Lamb-Fattening Experiments In Utah, E. J. Maynard, A. C. Esplin, S. R. Boswell Dec 1932

Bulletin No. 238 - Lamb-Fattening Experiments In Utah, E. J. Maynard, A. C. Esplin, S. R. Boswell

UAES Bulletins

This bulletin includes the results of Station Project 99-Fattening Lambs in Winter Drylot-which was begun at Monroe on November 15, 1928, and at Delta on November 13, 1929. The experiment was conducted for a period of four years at Monroe and for one year at Delta. Messers Alma and Milton Magelby of Monroe were closely associated with the Monroe experiment, furnishing the yards and the lambs as well as the feed used; the Monroe Lamb-feeders Association also cooperated in conducting this experiment. During the period that the Delta test was under way, Mr. J. F. Roe furnished the yards, the …


Bulletin No. 242 - Drainage Of Land Overlying An Artesian Ground-Water Reservoir: Progress Report, O. W. Israelsen, W. W. Mclaughlin Nov 1932

Bulletin No. 242 - Drainage Of Land Overlying An Artesian Ground-Water Reservoir: Progress Report, O. W. Israelsen, W. W. Mclaughlin

UAES Bulletins

Certain tracts of land in the West formerly used to produce grain and forage crops now produce only pasture grasses of comparatively low quality because of the water-logging and alkali accumulation which has occurred since irrigation was begun. Other tracts now producing only light crops of wild hay probably would produce profitable crops of alfalfa and clover, provided the water-table were lowered and the water-logged and alkaline condition of the soil removed. Still other areas are almost wholly nonproductive because of the concentration of excessive quantities of harmful alkali salts.

Knowledge concerning (1) the causes of water-logging, (2) economical methods …


Bulletin No. 239 - Wet Beet Pulp Compared With Corn Silage In The Dairy Ration, George Q. Bateman, George B. Caine Nov 1932

Bulletin No. 239 - Wet Beet Pulp Compared With Corn Silage In The Dairy Ration, George Q. Bateman, George B. Caine

UAES Bulletins

Wet beet pulp coming as a by-product from the sugar-beet industry in Utah is fed in varying amounts to dairy cows. Corn silage is also used to make up part of the dairy ration. Conflicting statements as to the value of the one feed as compared to the other indicated the need of more knowledge as to the value of pulp as compared to silage in the dairy ration. For this reason a study of the problem was initiated in February, 1926.


Bulletin No. 237 - Panguitch Livestock Experimental Farm Progress Report, B. F. Hulme Oct 1932

Bulletin No. 237 - Panguitch Livestock Experimental Farm Progress Report, B. F. Hulme

UAES Bulletins

The Panguitch Experimental Livestock Farm is located three miles north of Panguitch, the county seat of Garfield County. Prior to 1909 it was held by the United States as an Indian school. In 1909 the United States Congress transferred title to the State of Utah. Two years later, in 1911 , the Utah Legislature decided that this property should "be used as an experiment station in connection with the Agricultural College of Utah ...", and control was vested in the Board of Trustees of the Utah State Agricultural College.


Bulletin No. 236 - The Manufacture Of Cheese From Soft-Curd And Hard-Curd Milks, R. L. Hill, A. C. Merrill Aug 1932

Bulletin No. 236 - The Manufacture Of Cheese From Soft-Curd And Hard-Curd Milks, R. L. Hill, A. C. Merrill

UAES Bulletins

Little investigational work has been conducted on the effect of the hardness of curd of milk on the quality, quantity, and commercial value of cheese.

In July 1930, a preliminary report from the Utah Agricultural Experiment Station was made on these researches. This report indicated that for the manufacture of cheese hard-curd milk was far superior to soft-curd milk. This research is a continuation of that project.

Hard- and soft-curd milk used in the tests reported was obtained from Holstein cows. The fat content of each milk was practically the same. While the difference in curd hardness between the soft- …

Bulletin No. 234 - The Beet Leafhopper In Northern Utah, George F. Knowlton May 1932

Bulletin No. 234 - The Beet Leafhopper In Northern Utah, George F. Knowlton

UAES Bulletins

The first Utah sugar factory was erected at Lehi in 1891. Since that time many other factories have been built, and the growing of sugar-beets has become an important part of the agricultural program in many irrigated sections of this state. From almost the beginning, the tiny beet leafhopper, Eutettix tenellus (Baker), has threatened the very existence of this industry, and, in connection with the curly-top disease which it disseminates, has been responsible for the loss of many millions of dollars to the sugar-beet growers and sugar manufacturers of Utah. Poor prices, competition of other crops, sugar-beet nematode and crop …


Circular No. 98 - Insects In Relation To Alfalfa-Seed Production, Charles J. Sorenson Apr 1932

Circular No. 98 - Insects In Relation To Alfalfa-Seed Production, Charles J. Sorenson

UAES Circulars

Various insect pests have been suspected of causing the unsatisfactory alfalfa-seed yields that have been obtained in Utah during recent years. No specific information was at hand giving the amount and nature of the damage which these insects were suspected of doing.


Circular No. 97 - Growing Alfalfa-Seed, John W. Carlson Mar 1932

Circular No. 97 - Growing Alfalfa-Seed, John W. Carlson

UAES Circulars

SEED SHOULD BE GROWN FROM SUPERIOR VARIETIES AND STRAINS OF ALFALFA

The present tendency in alfalfa improvement is to establish narrow types or strains for special purposes and which are adapted to a particular set of conditions. It was at one time thought that an alfalfa variety with numerous types of plants would have a wider range of adaptability to diverse conditions and that inter- crossing among the different plants would maintain the vigor of the variety.


Bulletin No. 233 - Observations On The Use Of Commercial Fertilizers On The Arid Soils Of Utah, D. W. Pittman, Clarence Burnham Jan 1932

Bulletin No. 233 - Observations On The Use Of Commercial Fertilizers On The Arid Soils Of Utah, D. W. Pittman, Clarence Burnham

UAES Bulletins

Only within the last few years has the question of commercial fertilizers been worthy of serious consideration in Utah. It has been considered that commercial fertilizers were unnecessary in Utah (1) because arid soils retain their virgin fertility much longer than soils in the humid region which are subject to continual leaching by heavy precipitation, (2) because livestock have always predominated in Utah's agriculture due to the vast areas adapted only to range purposes and livestock means manure to maintain fertility, and (3) because alfalfa, our principal feed crop, is also one of the best plants for gathering nitrogen from …


The Composition Of Soil Colloids In Relation To Soil Classification, Horace Byers, M. S. Anderson Jan 1932

The Composition Of Soil Colloids In Relation To Soil Classification, Horace Byers, M. S. Anderson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

For a period of approximately fifteen years investigators in the Bureau of Chemistry and Soils have been engaged in the accumulation of scientific data concerned with colloid material of the soil. During this period a large volume of accurate information has been secured which has been published in the form of bulletins and journal articles. So far as the Bureau publications are concerned, but little has appeared concerning theoretical aspects of the composition of the colloid. They have concerned themselves, for the most part, with methods of isolation and estimation, and determination of general physical and chemical characteristics.

Circular No. 96 - Crickets And Grasshoppers In Utah, W. W. Henderson Nov 1931

Circular No. 96 - Crickets And Grasshoppers In Utah, W. W. Henderson

UAES Circulars

In the written history of Utah, especially that which is reflected in diaries and journals of the pioneer settlers and that found in the oldest publications, there is ample evidence that one of the most serious handicaps to progress in this "far-western" territory was the cricket and its near kinsman, the grasshopper. Three basic resources on which the first permanent settlers counted were: (1) Good soil suitable for raising crops to sustain life; (2) suitable climate to make possible the maturing of wheat, corn, and vegetables; and (3) sufficient water of good quality not only for home uses but for …

Circular No. 94 - Control And Eradication Of Bang's Abortion Disease, D. E. Madsen, W. H. Hendricks Jun 1931

Circular No. 94 - Control And Eradication Of Bang's Abortion Disease, D. E. Madsen, W. H. Hendricks

UAES Circulars

The seriousness of Bang's abortion disease in Utah has made it necessary to promote more definite plans toward its control and eradication. The economic losses encountered are brought about not only through the loss of the calves but by the lessened milk production and lessened sale value of the animals themselves. Breeding efficiency is lower and such cows are more subject to udder infections. Many states now require that cattle shipped into them be negative to the abortion test; indications are that more states will adopt similar regulations. The passage of such regulation by some states would seriously interfere with …

Bulletin No. 229 - Production Study Of 160 Dairy Herds: Wellsville, Utah, 1929, George Q. Bateman

UAES Bulletins

The condensed milk plant located at Wellsville, Utah, could use more milk to an advantage. The dairymen of the section were anxious to supply this demand. The dairymen and manufacturers cooperatively planned a survey to determine by what means this demand could be brought about: Should the dairymen increase the size of their herds? If not, what could be done to increase dairy production?

Bulletin No. 230 - San Juan County Experimental Farm: Progress Report, 1925-30, Inclusive, James H. Eagar, A. F. Bracken

UAES Bulletins

San Juan County, located in the southeast corner of the state, has a dry-farm area of approximately 600,000 acres extending from Monticello 26 miles south to Blanding and 6 miles north to Peter's Hill and stretching from the Blue Mountains east 30 miles to the Colorado line. One-fourth to one-third of this area is covered with timber consisting mainly of pinion pine, oak brush, and juniper commonly called cedar. Both the juniper and pinion are of value as fuel and building material, and the juniper has an additional value for fence posts. While small areas have been cleared of timber …

Bulletin No. 228 - Twenty Years Of Rotation And Manuring Experiments At Logan, Utah, George Stewart, D. W. Pittman

UAES Bulletins

It was the task of the pioneers to "subdue" the land. To them, this meant removing the brush, opening the ditches, and reducing the coarse sod to a fine mellow seedbed. They performed their task. Then for one to three generations the sons, grandsons, and the great grandsons of the pioneers made the land feed them. The idea of "subduing" the land was so firmly established in the West, that few realized the soil was being depleted in a manner somewhat similar to a bank account always drawn on but never replenished. Highly productive land is able to stand such …


Bulletin No. 227 - Soft-Curd Milk, R. L. Hill Jun 1931

Bulletin No. 227 - Soft-Curd Milk, R. L. Hill

UAES Bulletins

Data on the early studies on the curd character of milk are found in Utah Agricultural Experiment Station Bulletin 207 and, therefore, are not included here. The key to research in this field came to light with the development of the "Hill Test," the results of which were first published in 1923. This test furnished a means of quantitatively measuring the difference in curd character of various milks.

The term "soft-curd" milk originated with R. L. Hill to describe milk which on coagulation with pepsin or rennin forms a curd that is soft and clabbery in consistency, differing widely from …


Bulletin No. 226 - Alfalfa-Seed Production, J. W. Carlson, George Stewart May 1931

Bulletin No. 226 - Alfalfa-Seed Production, J. W. Carlson, George Stewart

UAES Bulletins

Utah's alfalfa-seed crop is of far-reaching importance. Since 1919, the growing of this crop has been a major industry in western Millard County and in that part of the Uintah Basin situated in Utah. These places are two of the relatively few large areas in the United States peculiarly adapted by climate for the successful growing of alfalfa-seed. As a cash crop, alfalfa-seed has a high commercial value. It is also the basis of the state's alfalfa hay crop, which in turn constitutes the foundation of Utah's livestock industry. Because of its wide dissemination, Utah's alfalfa-seed crop influences the feed …


Inheritance In A Wheat Cross Of Ridit X Utac, C. Leland Dalley May 1931

Inheritance In A Wheat Cross Of Ridit X Utac, C. Leland Dalley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Present-day plant breeding, on the foundation made many years ago, has achieved important scientific and economic results. By means of introductions and selections, superior strains such as Turkey and Kanred have been obtained. Through hybridization new combinations of characters result, combining desirable characters of different plant types in a single individual. In this program, wheat hybridization has occupied a worthy place.

Each year a number of wheat crosses are made at the Utah Experiment Station, the main purpose of which is to develop superior strains of wheat. Such an economic program is aided and hastened by studies in genetic behavior. …

Bulletin No. 224 - Muck Soil Investigations: Progress Report, Sanpete County Experimental Farm 1927-30, Inclusive, Le Moyne Wilson, George Stewart

UAES Bulletins

The estimated area of muck or peat soil in Utah is approximately 21,000 acres. The muck occurs in many valleys of Utah. The largest areas are in the Sanpete and Utah Lake Valleys. The area in the former is estimated at 6500 acres and the Utah Valley area at 9000 acres; the other areas, all more or less significant in size, are scattered throughout the state.

Investigations reported have been confined entirely to the Sanpete area which is located near the south and bottom end of the valley and is west of the towns of Chester, Ephraim, and Manti. During …


Circular No. 93 - Better Sugar-Beet Culture For Utah, George Stewart, D. W. Pittman Apr 1931

Circular No. 93 - Better Sugar-Beet Culture For Utah, George Stewart, D. W. Pittman

UAES Circulars

Utah was one of the first states to begin sugar-beet growing. The industry grew rapidly, favored by the climate, by the naturally productive soils, by the freedom from pests, and by the system of intensive irrigation agriculture. California and Utah were among the leading beet-producing states at the time of the World War, and under the stimulus of high prices they remained so until the great depression of 1920. After that, the frequent occurrence of curly-top and the rapid spread of nematode, together with the low price resulting from increased cane sugar production in the tropics and from other causes …


Bulletin No. 225 - Progress Report: Carbon County Experimental Farm, 1927-30, Inclusive, I. D. Zobell, George Stewart Apr 1931

Bulletin No. 225 - Progress Report: Carbon County Experimental Farm, 1927-30, Inclusive, I. D. Zobell, George Stewart

UAES Bulletins

The agricultural problems of the Carbon County Experimental Farm and of the locality which it serves are distinctly different from those of most of the farming localities of Utah. The low and uncertain winter rainfall, the comparative "rawness" of the soils, together with their almost infinite stickiness when wet, and the presence of considerable alkali throughout their body makes them peculiarly sensitive to time and manner of treatment and causes them to absorb water slowly and to erode readily.


Circular No. 92 - Torrential Floods In Northern Utah Jan 1931

Circular No. 92 - Torrential Floods In Northern Utah

UAES Circulars

On account of the recurring nature and the destructive character of the floods which have devastated property in Davis County and elsewhere in recent years, it appeared advisable to make a special study of the situation, I, therefore, in 1930, appointed a commission of citizens whom I deemed especially qualified, including practical engineers, geologists, foresters, and stockmen, asking them "to study the origin and cause of floods in Davis County and other parts of the state, and to ascertain whether any flood prevention measures are feasible".
