The Genetics Congress, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Mice and men reported from

Edinburgh after the Congress

(JOURNAL OF HEREDITY for

September 1939) but since then there

has been silence, as far as getting into the

record any details of the Congress. On

account of the disruption to trans-Atlantic

travel caused by the declaration of

war between England and Germany,

September 3, the American delegation to

the Congress was considerably delayed

in getting back. Only two failed ultimately

to return, Dr. and Mrs. F. W.

Tinney of the Division of Farm Crops

of the University of Wisconsin. They

were among about a dozen members of

the Congress who …

Bulletin No. 290 - Phosphate In Utah, J. Stewart Williams

UAES Bulletins

Agitation for the development of the western phosphate field as part of the national program of conservation and economic rehabilitation has, in the last three years, focused public attention on the phosphate reserves of Idaho, Montana, Wyoming and Utah. In every conference or discussion on this subject, the minds of Utah's representatives have naturally turned to the question, "What is Utah's share in this great natural resource?" Obviously nature pays no heed to political boundaries, and neither does the prosperity of Utah's citizens depend solely upon that which is circumscribed within the state's boundaries. Nonetheless, it is necessary for Utahns …

Bulletin No. 289 - Business Analysis Of Farms In Utah County, Utah, Walter U. Fuhriman, W. Preston Thomas

UAES Bulletins

Project 179 of the Utah Agricultural Experiment Station - "A Study of the Agricultural Resources of Utah and their Utilization" - was set up in April 1936 as a state-wide project. The object of this project was to measure by areas the basic agricultural resources of the state and to translate the information collected into a program of more efficient use. The more specific objectives were: (1) classification of agricultural lands of Utah according to present and potential productivity and use; (2) determination of the net productive area of agricultural lands and water supply now available, or which may be …

Bulletin No. 288 - Draingage And Irrigation, Soil, Economic, And Social Conditions, Delta Area, Utah Division 4: Social Conditions, Joseph A. Geddes, Carmen D. Frederickson, Eldred C. Bergeson

UAES Bulletins

This study is a part of a more comprehensive one which was organized in 1928 for the purpose of ascertaining what conditions existed in bonded irrigation and drainage districts which were unable to. liquidate obligations incurred.

The first such area to be studied was the Delta Area in Millard County. This area was selected for this study because of the pressing need for more detailed and wider information than was available to either the farmers or the bondholders and because available facts based on careful study might aid in achieving fairer settlements. These data might also assist other areas in …

Bulletin No. 287 - Tests Of Corn Varieties And Hybrids In Utah, R. W. Woodward, D. C. Tingey, R. J. Evans

UAES Bulletins

The corn acreage in Utah is only about half that planted in barley and approximately one-fourth that sown to spring wheat. During the period 1910-30 this acreage was about equally divided into corn for grain, corn for silage, and corn fed to livestock in the field (table 1) . Since 1930 there has been a gradual increase in the acreage of corn grown for silage with the exception of the years 1936 and 1937.

Bulletin No. 284 - Lygus Bugs In Relation To Alfalfa Seed Production, C. J. Sorenson

UAES Bulletins

This investigation, which continued during the two succeeding years, had four primary purposes: (1) to determine the distribution of these plant bugs and the intensity of their infestation in the alfalfa-seed districts of the state; (2) to ascertain whether these bugs constitute an important factor, either causing or contributing to, the excessive flower-drop annually occurring in alfalfa-seed fields, or if they are otherwise responsible for decreased yields of alfalfa seed; (3) to study the general biology of these insects with particular reference to their life histories in alfalfa as the host plant; and (4) to investigate possible practical methods for …

Bulletin No. 286 - Some Trends In Utah's Agriculture, Walter U. Fuhriman

UAES Bulletins

During the last two decades agriculture has been subjected to many strains and stresses- social, economic, physical, and biological. Infestations of noxious weeds and insect pests have in some instances necessitated changes in crops grown and in farming practices. Changes in precipitation have induced alternate expansion and contraction of cultivated acreage in certain areas. Improved machinery has reduced the demand for farm labor, caused shifts in crops grown and in farm population. Changes in dietary habits have increased the demand for some farm commodities and decreased the demand for others, while wide fluctuations in farm prices have wrought rapid changes …

Bulletin No. 282 - Pioneering In Western Agriculture

UAES Bulletins

A resume of the First Half-Century of Research 1888 - 1938 at the Utah Agricultural Experiment Station including the Biennial Report 1936 - 1938.

The Utah Agricultural Experiment Station in reaching the fiftieth year of its history can look back upon a brilliant record of achievement covering the practical as well as the more fundamental problems of agriculture in this arid state. The difficulties encountered in conquering deserts down through human history have demonstrated the mastery of man's spirit over his physical environment. Man's destiny to multiply, subdue, and replenish the earth cannot be accomplished by enjoying the fruits of …

Bulletin No. 280 - Sinusitis Of Turkeys And Its Treatment, D. E. Madsen

UAES Bulletins

Sinusitis has long been recognized as one of the barriers to profitable production of chicken products; and with the growth of commercial turkey production in the west its existence in this bird has become increasingly significant. In Utah areas considerable loss is encountered yearly from this disease in turkeys. This loss has prompted some investigations as to what measures may be adopted for its control.

Bulletin No. 279 - The Fruit Tree Situation In Utah, A. L. Wilson, A. L. Stark

UAES Bulletins

The fruit industry in Utah is not large when compared with the total production of the United States. The year 1935 was a favorable fruit season for Utah and yet the state produced only 0.54 percent of the United States' apple crop, 1.30 percent of the peach crop, 0.31 percent of the pears, and 3.72 percent of all cherries. Utah does, however, produce between 10 and 15 percent of all sweet cherries. Even though the Utah fruit industry represents such a small part of the national industry, a great many people of the state are dependent upon it, either wholly …

Bulletin No. 281 - Sorghums Varietal Tests In Utah, R. W. Woodward, D. C. Tingey, R. J. Evans

UAES Bulletins

Sorghums are not grown to any appreciable extent in Utah except in the Virgin River valley in the southwestern portion of the State. No experimental work on sorghum culture had been done prior to 1931 except on the dry land of Juab County near Nephi. Those early tests, discontinued after 1917, indicated that sorghums were poorly adapted to such conditions.

Numerous improved varieties have been produced since that time, some of which are adapted to relatively short growing seasons.

This bulletin will discuss the practicability of growing some of these varieties of sorghum in Utah and their economic value compared …

Bulletin No. 278 - Should Flax Be Grown In Utah, R. W. Woodward, D. C. Tingey, A. C. Dillman

UAES Bulletins

Flax has been considered as a possible crop for growing under irrigation in Utah because of its high acre return in some of the northern States. One of the functions of a State experiment station is to test new crops and varieties. A series of experiments , therefore, has been conducted in Utah to determine the yields of flax as compared with small grains both under irrigation and on dry lands. This bulletin report s a summary of the results of these experiments together with a discussion of comparative returns from flax and small grains.

Two types of flax, seed …

Bulletin No. 277 - A Study Of Utah's Winter Range: Composition Of Forage Plants And Use Of Supplements, A. C. Esplin, J. E. Greaves, L. A. Stoddart

UAES Bulletins

Range forage provides the foundation for the maintenance ration available for most sheep wintered in Utah. The nature and amount of supplemental concentrate or roughage needed with this forage to provide an adequate and efficient ration for sheep naturally depends on the nature and amount of range forage available. Present uncertainty as to the relative merits of the various available supplements originates largely through a lack of definite knowledge as to the composition and feeding value of the various range plants that go to make up the range-forage supply on the particular range in question.

The Effects Of X-Rays Upon The Roots Of Zea Mays, Bernard Louis Wolfe

Bachelors’ Theses

Since. the discovery of X-rays by Rontgen in 1895, the majority of published papers dealing with the influence of these rays on plant life have considered their general effects on physiological processes including rate of seed germination and growth, respiration, and movements. A large number of investigators have worked on the morphological and cytological aspects while comparatively few workers have been interested in the histological effects of the stimulated tissues. The purpose of this thesis is to show the histological, morphological, and cytological effects of X-rays upon the root tips or the Zea Mays as well as the effects these …

Crow-Waterfowl Relationships Based On Preliminary Studies On Canadian Breeding Grounds, E. R. Kalmbach

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

With the object of obtaining a current insight into the relationship of crows to waterfowl on their breeding grounds, a study was inaugurated in the spring of 1934 and continued through the nesting season of that and the following year. As originally planned, it called for field studies both in Canada and in the northern United States, but drought conditions had so drastically reduced the breeding population of ducks within our borders by the spring of 1934 that, after a futile effort to locate suitable areas in this country, plans were changed and the studies were restricted to Canadian areas …

Diseases Of Upland Game Birds, J. E. Shillinger, L. C. Morley

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

Until recently the diseases of upland game birds received comparatively little specific study, except in a few outbreaks in which serious losses were observed. Though highly destructive, many of these outbreaks were of such short duration that the investigations undertaken were chiefly to learn the cause of death and usually were discontinued when losses were no longer noticeable. It has become increasingly evident, however, that every year great numbers of game birds die of disease, the decreases in their numbers frequently occurring in sections closed to hunting, even though food, cover, and other environmental conditions appear ideal. The disease problems …

Local Bird Refuges, W. L. Mcatee

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

Birds appeal strongly to the interests and affections of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.

Birds feed upon practically all insect pests. They are voracious, are able .to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.

For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their …

Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas

UAES Bulletins

A large portion of the agriculture of Utah, outside of the desert range areas, is characteristically heterogeneous rather than homogeneous in character. Marked differences in size of farm, in crops grown, in livestock kept, in yields, and in farm organization occur within short distances. This diversity is due in large measure to differences in soil, elevation, topography, and other physical features and to climatic characteristics such as amount, kind, and distribution of precipitation and length of growing season. The physical and climatic features are the chief determinants of the amount of water potentially available for the irrigation of the crop …

Bulletin No. 274 - Influence Of Rotation And Manure On The Nitrogen, Phosphorus, And Carbon Of The Soil, J. E. Greaves, C. T. Hirst

UAES Bulletins

All agricultural plants require carbon, hydrogen, oxygen, nitrogen, calcium, potassium, magnesium, sulfur, phosphorus, iron, and probably traces of other elements for their normal growth and fruition. The growth of farm crops is dependent upon an available supply of these elements, and the extent of growth is governed by the one present and available in least quantity in proportion to the plant's needs. Of the essential elements, all plants secure two (carbon and oxygen) from the air, one (hydrogen) from the water, and the others from the soil. Most soils contain sufficient plant nutrients for normal plant production, with the exception …

Bulletin No. 272 - Transmissibility Of Bang's Disease Among Dairy Cattle In A Utah Dairy Village, D. E. Madsen, O. G. Larsen

UAES Bulletins

For a number of years it has been generally recognized that one of the most satisfactory methods of controlling Bang's disease in dairy cattle is to locate spreaders by means of the agglutination test and to eliminate them from the herd. The success of such a plan in relation to Utah dairy herds was not clearly understood because of the physical farm set-up peculiar to many communities in this state. The village of Hyde Park where this study was made is organized on such a community basis. Usually, a house and livestock buildings are constructed on the town lot, consisting …

Bulletin No. 266 - Comparative Size Of Rural And Urban Utah School Children As Determined By The Weight - Height - Age Relationship, Almeda P. Brown

This is the second of a series of bulletins based on a study of Utah village life which was begun in 1927. The purpose of the investigation was to determine, under prevailing conditions, whether for farm people farm-living is less desirable than village-living. Four type villages were selected in as many counties for field studies.

Bulletin No. 267 - Muck-Soil Management And Crop-Production Studies: Sanpete County Experimental Farm 1927 To 1933, Inclusive, Le Moyne Wilson

UAES Bulletins

The muck soil area in Sanpete County, where these investigations were conducted, comprises approximately 6500 acres, 4209 of which are included in the San Pitch Drainage District. This region is located in the south end of Sanpete Valley and west of the towns of Ephraim and Manti. During part of the year the lands involved were subject to overflow by the San Pitch River. Water covered most of the area early in the winter, and during the spring months high water kept it submerged until June. Before the neighboring communities were settled by white people, this area was probably submerged …
