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 …

Carbon County is the greatest bituminous coal-producing district in the state and ranks as one of the largest and best in the Intermountain West. In 1934 there were twenty-six operating coal mines from which approximately 5,000,000 tons of coal were mined each year. These mines create work for hundreds of men. Many people in this section farm in the summer and mine during the winter months. In 1934 but 20,000 acres of land in this section were under cultivation, with little possibility of reclaiming additional land. Prior to 1928 crops had been somewhat restricted on account of the limited water-supply; …

The Delta Area, in which most of the alfalfa-seed investigations and crop studies reported in this bulletin were conducted, is located in Millard County which is in the west-central part of Utah. This area lies in the Sevier Desert, within the eastern boundary of the Great Basin in the northeastern part of the county.
Parts of the area, particularly the farming sections near the towns of Oasis, Deseret, and Hinckley, have been among the oldest and most consistent alfalfa-seed producing sections of the United States. The peak of alfalfa-seed production in Millard County was reached in 1925, when approximately 14,000,000 …

UAES Bulletins
In sugar-beet producing areas of the Intermountain West and Pacific Coast beet by-products constitute a most economical source of feed for fattening livestock.
In Utah there are available each year some 144,000 tons of wet beet pulp and some 20,000 tons of beet molasses; in addition, about 6500 tons of dried molasses beet pulp are available in the form of meal or pellets.
Practically all of this livestock feed supply, with a nutritive value equivalent to approximately 41,000 tons of corn or barley, has been fed, together with alfalfa hay, to cattle or sheep for maintenance or in the production …

The Tympanis Canker Of Red Pine, John Raymond Hansbrough
The Tympanis Canker Of Red Pine, John Raymond Hansbrough
Yale School of the Environment Bulletin Series
A new disease of red pine has recently been found in southern Connecticut, Rhode Island, eastern Massachusetts, western and central New York, northern New Jersey, eastern Pennsylvania, central Ohio, and southern Michigan. It is of serious consequence only on plantation-grown red pine, but it also occurs occasionally on eastern white pine. On the former host it is characterized by axially elongated, annual main-stem cankers which are always centered at the nodes. Infection takes place through adhering lateral dead branches and the growth of the fungus after it gains entrance to the stem.is usually very rapid-Le., cankers up to three feet …

Bulletin No. 258 - Alfalfa-Seed Investigations In Utah, John W. Carlson
UAES Bulletins
For many years alfalfa-seed production problems have engaged the attention of investigators in various parts of the world. Those factors which are regarded as of greatest importance in seed-setting are general climate, current weather, air humidity, soil moisture, and insect relationships within the various alfalfa-seed districts. Some attention in research has been given to pollen fertility and ovule sterility, as well as to general flower dynamics in relation to environmental conditions. Efforts have been made to develop strains of alfalfa having pollen that is resistant to injury by moisture or having self-tripping flowers or autogamous strains of alfalfa whose flowers …

Bulletin No. 263 - Relative Produciton Of Feed Grain From Spring-Grown Cereals In Utah, R. W. Woodward, D. C. Tingey
UAES Bulletins
Nearly one-third of the cropped acreage of Utah is devoted to cereals. Except for wheat, most of these crops are fed locally. In addition to this, an average of over a million bushels of corn, barley, and oats is shipped into the state each year to be used in various livestock and poultry industries.
The purpose of this publication is to show the comparative amount of feed produced by the different crops--wheat, oats, barley, and corn--under similar conditions as determined for the specified four years by acre-yields obtained in various agricultural regions of the state. One should bear clearly in …

The United States Census Report for 1930 shows that approximately 25 per cent of Utah farmers were growing oats at that time. Leading counties in oat production were Sanpete, Utah, Emery, Cache, and Weber, each of which produced over 100,000 bushels. Sanpete County produced over 200,000 bushels, whereas Boxelder, Sevier, Duchesne, and Salt Lake Counties produced slightly less than 100,000 bushels each.

UAES Bulletins
Wheat was one of the first crops grown by early Utah settlers. It has since occupied an important place in the agriculture of the state. While wheat is almost the only crop grown successfully on dry-lands, it is also important under irrigation. Thirty per cent of the wheat acreage of Utah in 1929 was spring-sown, which produced 44 per cent of the state's production. Eighty-seven per cent of the spring wheat acreage was grown under irrigation, this acreage producing 92.3 per cent of the total spring wheat crop. Thirty-eight per cent of Utah farmers were growing spring wheat in 1929; …

Relief, a new variety of hard red winter wheat resistant to most forms of covered smut occurring in Utah, was bred by the Department of Agronomy, Utah Agricultural Experiment Station. Produced by hybridization, it resulted from a response to an urgent need for some more effective means of controlling the serious disease of wheat known as covered smut or bunt. In addition to being resistant to forms of covered smut which have caused such heavy losses to wheat farmers of central and northern Utah and southern Idaho, experiments have also shown that it appears equal in all other respects (such …

UAES Bulletins
This bulletin constitutes a final report of some phases of cooperative drainage studies in Cache Valley, Utah. The drainage problem in Cache Valley is typical, in many respects, of drainage problems in other irrigated valleys of Utah and the West in general. Application of the principles indicated by the problems will doubtless add materially to the productivity of the land in the several communities concerned and will also contribute to the advancement of public welfare in the general improvement of health, economic, and social conditions. Alkali and water-logging affecting large areas are causes not only of low productivity of the …

Relative Efficiency Of Roots And Tops Of Plants In Protecting The Soil From Erosion, J. E. Weaver
Relative Efficiency Of Roots And Tops Of Plants In Protecting The Soil From Erosion, J. E. Weaver
Department of Agronomy and Horticulture: Faculty Publications
Plant cover, soil and topography are the major factors concerned in the problem of erosion. During the earlier studies, conducted largely by engineers, chief emphasis was placed upon topography. Following extensive work by pedologists, it is now generally conceded that type of soil is an equally important factor. Intensive studies on the effect of plant cover reveal the extremely important role played by plants in holding the soil against the forces of erosion. In this preliminary account of the relative effectiveness of roots as compared to tops in holding the soil in place, the results are based on extensive experiments …

Response Of The Prairie To The Great Drought Of 1934, J. E. Weaver, L. A. Stoddart, W. M. Noll
Department of Agronomy and Horticulture: Faculty Publications
Drought during the growing season of 1934 was the greatest ever recorded in the prairie region. It offered an exceptional opportunity to study the response of native plants to extremely adverse water relations. Measurements of the environmental factors of the prairie, in connection with various grassland researches, have now been completed, except for one year, for the seventeenth consecutive growing season. In a summary of findings at the end of twelve years it was stated that although periods of drought are liable to occur at any time, and especially after midsummer, yet only twice during these twelve years was the …

It is necessary only to observe groups of rural children to become convinced that too many of them are deprived of their rightful heritage of positive health.
Why children playing together, working together, under conditions which apparently vary but little, should exhibit such wide variation in health conditions, is a question of vital importance to all concerned with the care of children.
It was with the hope of finding some of the causes behind these variations that the present study was initiated. That the problem is complex and intricate was fully realized, and no hope was entertained that its solution …

Masters Theses & Specialist Projects
The campus of Western Kentucky State Teachers College was laid out in 1910 by Mr. Henry Wright, landscape architect, with the view of planting ornamental shrubs and woody and herbaceous plants indigenous to Kentucky. In more recent years the gardens on the grounds of the Kentucky Building have been planted with many species of Kentucky plants.
This study was undertaken for the purpose of making a scientific classification of the flowering plants on the campus of Western Kentucky State Teachers College.
