Laboratory Applications Of Present Day Knowledge Of The Hormone Of The Anterior Lobe Of The Pituitary Gland, Herman F. Geske

Bachelors’ Theses

The history of a pregnancy diagnosis is an old one. In the report of Dr. S. Ashheim is a note which bears this out. The women of ancient Egypt used a rather crude method. Whether it was an efficient test the records do not state. Considering the fact that pregnancy and germination and growth are correlative, these women of the Nile probably were not so far wrong theoretically, whatever the practical results may have been. Their method was to put barley and wheat grains in a pot. These grains were wettened with urine from a woman who thought herself pregnant.

Circular No. 85 - Chlorosis Yellowing Of Plants: Cause And Control, F. B. Wann

UAES Circulars

Chlorosis is a disease of plants, the characteristic symptom of which is the yellowing of the leaves. The disease is of sporadic but widespread distribution in Utah and the aggregate losses caused by it are undoubtedly greater than those of any other one disease. Not only are many plants killed, or weakened to such an extent that only inferior crops are produced, but many areas of land which might otherwise support profitable orchards have been abandoned or planted to other crops because of the disease.

The Symptoms Of Spindle Tuber And Unmottled Curly Dwarf Of The Potato, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The differentiation of the virus diseases of the potato on the basis of symptoms is an important but difficult phase of the virus problem. A knowledge of the variation in symptoms due to environmental factors is necessary both in investigational work and in the practical application of our knowledge to the control of these diseases in the field. A fairly comprehensive knowledge of the masking effect of certain environmental factors upon the symptoms of the mosaic group has been obtained through the work of various investigators. Considerably less information is available concerning the effect of environment upon the symptoms of …

A Study Of Preprations From Buckwheat Hulls, Rudolf A. Zivnuska

Bachelors’ Theses

Industry is trying to make use of all possible material. In an age of great manufacturing plants, efficiency Is decreased and costs mount rapidly whenever a waste product tends to be formed in a process. The problem resolves itself into selling someone else the waste products in a modified form, if necessary. At the present time, waste products support industries to which they were formerly a liability. In the Ford wood waste distillation plant in 1929, over $2,100,000 worth of benzol was sold. This is in addition to gas, charcoal, methanol and power gotten from the exothermic action from the …

Principles Of Irrigation Farming As Developed By American Field Experiments, Prabh Dyall Sikka

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Irrigation is "the artificial application of water to the soil for the purpose of getting large and steady crop yields". It is supplementary to rainfall and the quantity of water applied and the time of application, therefore, must be determined by the character of the rainfall. Irrigation is usually practiced in those regions which have low rainfall as natural precipitation at such places is insufficient to meet the full water requirements of crops.

A Study Of Bull Associations, Arthur J. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

"A cooperative bull association", according to the United States Department of Agri culture, is "a farmers' organization formed for the purpose of joint ownership, use, and exchange of high class, purebred dairy bulls."

The members of the association are divided into three or more groups of neighboring farmers, each group being known as a block. A block may consist of one herd or several herds and contains from 40 to 60 cows. One bull is used in each block, and in order to prevent inbreeding, each bull is moved to another block every two years. If all the bulls live …

A Research Study Of Lamb Feeding In Winter Dry Lots At Monroe, Utah, 1928-29, George R. Henderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

By reason of the topography of the land, Utah is and probably will remain a livestock grazing state. As far as agriculture is concerned over 90 percent of the area is suitable for grazing only. This grazing range is used by cattle and sheep.

The Use Of Chlorates For The Eradication Of Certain Perennial Weeds In Utah, Lionel Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Perennial weeds have retarded agricultural progress, since their first appearance in cultivated fields. They have grown and survived the destructive efforts of the farmer and agricultural scientist, over a great period of time. Many farmers have become discouraged and much valuable land has lain idle because of this wasteful weed persistence.

These dismal consequences have stimulated constant effort at experimental stations to discover more effective methods of battling the pest. The use of chemicals has been one of the most prominent weapons and, of the most recent chemicals tried, the chlorates are the most promising.

Bulletin No. 216 - Notes On Miscellaneous Insects Of Utah, Herbert J. Pack

UAES Bulletins

Doctor Pack, as station entomologist, was studying many problems, all of which could not receive constant attention. Consequently, much of the information recorded is far from complete but has value as a record of occurrence or as it bears on phases of the life history of forms present in this area. The following bulletin consists of notes on the various species of insects in Utah.

It has been the object of the author to present in this thesis the chemical composition of the eggs of the duck and the goose, the chemical composition of the abdominal adipose connective tissue, the fat constants of the visceral fat of the goose, the egg-yolk fat of the goose and duck, and the subcutaneous fat of the goose.

Bulletin No. 215 - Cost Reduction In Dry-Farming In Utah, P. V. Cardon

UAES Bulletins

Major economic influences, known to be affecting farming generally throughout the United states, are forcing the adoption of cost-reduction methods in dry-farming practice in Utah.

The methods of cost reduction that are being adopted include (a) cultural methods involving the control of weeds, preparation of the seedbed, the treatment of seed for the control of smut, and the use of superior strains or varieties of wheat, all of which are expected to reduce the cost per bushel by increasing the acre-yield; and (b) the more economical use of labor and equipment on the area farmed. The area farmed may be …

Swine Sanitation, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

From the very beginning of Nebraska's agricultural development its farmers have recognized that the production of swine must of necessity accompany the growing of corn. The latter, one of the state's most important staples, cannot be marketed in a more economical manner than after having been transformed into pork, bacon, and lard. As a result the state has for many years maintained a rather dense swine population mainly divided into large herds kept on relatively small areas of land. This density of population, as well as certain practices in management and selective breeding, has brought about conditions favorable for the …

Common Fossil Pollen Of The Erie Basin, Paul B. Sears

Papers in Ecology

This paper is intended chiefly to assist in the identification of common and significant pollen found embalmed in bog deposits in north-central United States. Before proceeding with the actual key and description, a brief explanation seems to be in order.

For a number of years European botanists have been counting the various species of pollen found at different levels in bogs. Such statistics have been used to trace the course of plant succession and the climatic changes of which it is held to be the expression. Stark (9) has prepared a concise summary on the subject up to about 1924; …

Circular No. 84 - Building Young Deciduous Fruit Trees, Francis M. Coe

UAES Circulars

The modern fruit tree in a commercial orchard, to survive in present-day competition, must bear heavy crops. The mechanical strength which determines whether it can hold its heavy load successfully or whether it will be broken down and become a liability to its owner is determined to a large extent by the training it has received the first two or three years after planting.

Seed Corn Treatments At The North Platte Substation, L. L. Zook, N. E. Jodon

Nebraska Agricultural Experiment Station: Historical Circulars

For the past several years, much publicity has been given to the matter of seed corn treatments. Various commercial compounds have been widely and extravagantly advertised for general farm use as seed corn disinfectants. The effectiveness of many of these compounds in controlling certain seed-borne diseases has been demonstrated in some of the more humid areas of the corn belt. Very little is known of the distribution of these diseases and the extent to which they affect the germination and productiveness of seed corn in the drier or semiarid sections.

The Effect Of Soil Moisture On The Establishment Of Spruce Reproduction In British Columbia, Percy Munson Barr

Yale School of the Environment Bulletin Series

Most of the field work has been conducted at the Aleza Lake Forest Experiment Station, in the valley of the Upper Fraser River, near the city of Prince George [British Columbia].

I. A series of twelve permanent plots (numbers 1 to 12) was established for the purpose of studying the occurrence of natural reproduction on various types of seed bed, under different densities of overwood and on northern and southern aspects. 2. A second series of four plots (numbers 17 to 20) was laid out in logged-off land for the purpose of studying the survival and growth of advance reproduction …

Diameter Distribution Series In Evenaged Forest Stands, Walter H. Meyer

Yale School of the Environment Bulletin Series

BOTH in natural and in planted forest stands trees vary greatly in diameter, form, and height, even when the trees are all of the same age. For example, in a natural forest stand of Douglas fir, aged seventy years and located on a poor growing site, the trees may range from 5 to 18 inches in diameter at breast height (4.5 feet above the ground). The numbers of trees in the range of diameter .classes are not equal, but are small in classes at the extremes of the range and large in the central classes. If these numbers were plotted …
