Stem Blight Of Alfalfa In Utah: A Complex Of Two Distinct Diseases, William E. Rader

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1908, Sackett described for the first time what appeared to be a new bacterial disease of alfalfa in Colorado. To this particular disease he applied the name “stem blight" and attributed the cause to a bacterium, Pseudomonas medicaginis n. sp. For some two decades or more Sackett's work on this disease was accepted. During this time stem blight, which was first thought to be indigenous to the western United State, was reported from nine states east of the Rocky Mountains. In 1933, Johnson and Valleau described a disease of alfalfa, characterized by stem lesions very similar in appearance to …

Bulletin No. 306 - Report Of The Agricultural Experiment Station Utah State Agricultural College, Logan, R. H. Walker

UAES Bulletins

The agricultural experiment stations have contributed in a very material way to the progress of agriculture in the United States not only by the development of better crops and livestock and production practices, but, through basic research on the many and varied problems of agriculture, they have furnished an understanding of those principles upon which progress must depend.

The permanent value of these research centers to the progress of agriculture is no better illustrated than in the present emergency. The ability of farmers to meet the tremendous additional contributions to defense in the way of increased food supplies is dependent …

The Isolation Of Some Nonsymbiotic Nitrogen Fixing Organisms Occurring In Some Utah Soils, Richard B. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plants require ten elements in appreciable quantity and several others in smaller amount for their continued and normal growth. Three of these necessary elements, nitrogen, phosphorus, and potassium are most important because they occur in the soil in quantities which are usually small in proportion to that needed by the plants. Of these three, nitrogen is in most cases the limiting factor because of the ease with which it may be leached from the soil and comparatively large amount assimilated by plants. These factors coupled with the inhibiting high cost of artificially replacing it in the form of commercial fertilizers, …

Sexuality And Related Subjects In Ustilaginales (Smuts), William Vance Wright

Biology

The Ustilaginales represent a group of fungi which are all parasitic upon the higher flowering plants. The mycelium is hyaline, somewhate septate, mostly intercellular, branched, and practically restricted to the interior of the host. At maturity the mycelium often disappears, partially, at least, through gelatinization. The fertile mycelia becomes compacted into the masses which give rise to numerous chlamydospores. That is, the chamydospores develop directly from the mycelia. Upon germination, each chlamydospore sends out a short tube called a promycelium. From the promycelium are budded off sporidia, generally four. If the sporidia find logment on suitable host tissue, they germinate …

A Study Of The Library Facilities And Personnel Of Five Selected High Schools Of Northern Utah, Clyde H. Morris

Life History Of The Pale Western Cutworm Agrotis Orthogonia Morrison, Heber F. Thornley

Biology

The pale western cutworm Agrotis orthogonia Morr. Is a native insect of the arid-lands of western United States and Canada. Devastation of dry-land grains has marked the insect as the most destructive cutworm in the west. Because of the underground feeding habits of this insect the usual methods of control, so effective with the army cutworm and other cutworm species, have all failed.

Physiological Investigations Of Two Strawberry Root Rot Fungi, Fusarium Orthoceras Ap. And Wr., And Cylindrocarpon Obtusisporum (Cke. And Hark.) Wr., Herbert B. Currier

Biology

During recent years strawberry growers in widespread areas have been concerned with losses attributed to a root disease commonly termed "Black Root Rot of Strawberries". This malady is especially severe in Utah. Richards and McKay (18)¹ report that losses are such as to render commercial strawberry growing unprofitable in certain areas. These investigators found, in isolation studies of diseased strawberry roots, that the disease is evidently not due to the attack of a single pathogene, but that several fungi, each apparently capable in itself of producing infection, may act collectively in producing a "disease complex".

Circular No. 80 - Domestic Slaughtering, Cutting, And Curing Of Pork, Harry H. Smith

UAES Circulars

The practice of slaughtering hogs on the farm is being followed rather extensively by the farmers of this state. It is an economic practice and should be more generally followed because by this practice a supply of meat is available throughout the year. In all ages meat has been the principal article of diet of the ruling races. It is a natural and necessary part of man's diet. The races of people who have not included meat in their diet are today numbered among the weaker and more backward nations.

The Effect Of Sulfur On The Microflora Of The Soil, J. M. Fife

Biology

Sulfur is one of the required elements for all plants and animals. Does the Greenville soil contain sufficient sulfur for the maximum bacterial activities when it contains only .0068 per cent?(7) It is the object of this paper to present data which has been obtained in trying to answer this question. The Greenville soil is an ideal media in which to study the effect of sulfur on the soil microflora due to the abundance of all the required elements with the exception of sulfur, and its most interesting microflora (6) (7).

A Contribution To Our Knowledge Of The Aphididae Of Utah, George Knowlton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are many groups of insects in Utah that have not been touched in a systematic way up to the present time, and to the knowledge of the author no systematic work has been done on the homopterous family Aphididae.

Due to the very common occurrence of the aphids, or plant lice, and the need for a simple key that would aid in the determination of these insects, this work was commenced in June 1923, continuous work being carried on in collecting, determining, drawing and describing, up to the present time.

Viability Of Bacillus Typhosus In Media Of Various Kinds In Relation To The Hydrogen Ion Concentration, Barrett Elmer

Biology

A careful study of the literature on the viability of the typhoid organism reveals a startling lack of agreement. Potter, in a series of experiments, comes to the conclusion that if a repressing effect occurs on B. typhosus because of the acidity of milk due to souring, it is so small as to be negligible and as a consequence such acidity cannot be depended upon to eliminate the organism. Baker, after experimenting on milk and butter, isolated the typhoid organism after 45 days from milk and after 151 days from butter. Frankel and Kister find the typhoid organism perishing in …

Bulletin No. 185 - The Influence Of Nitrogen In Soil On Azofication, J. E. Greaves, D. H. Nelson

UAES Bulletins

Many soils of the arid west have a rich active azofying flora. This is due in no small measure to their composition. They are high in calcium and magnesium carbonate and contain a good supply of available phosphorus and potassium but have a low nitrogen content. They are poor in organic carbon; hence, their native supply of energy is limited. It is well-known that a liberal supply of rapidly decaying organic matter is beneficial, and this is being supplied to some soils in the form of manures. This will increase the nitrogen content of the soil. What effect will this …

The Movement Of Ground Water And Its Relation To The Drainage Of Irrigated Lands, Ernest O. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One needs but to review the history of the irrigated projects of the West to see clearly the importance of drainage. Since the passing of the Reclamation Act in 1902, the construction of drainage work by the United States Reclamation Service on seventeen projects located in thirteen western states represents about 12 percent of the expenditures from the Reclamation Fund. The portion for drainage has been spent during the last few years. This work has required an annual expenditure of about $1,000,000 or a total of $8,000,000 to July, 1922⁽¹⁾. The work completed is estimated to have reclaimed …
