The Vitamin A And The Vitamin E Content Of Field-Cured And Artificially Cured Alfalfa Hay, I. L. Hathaway, H. P. Davis, R. R. Graves

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A comparative study of the vitamin A content of field-cured and artificially cured alfalfa was made by comparing the growth produced by 124 rats receiving alfalfa hay as their source of vitamin A. From the results of this study, in which the experiments were duplicated, it is concluded that under the conditions of these experiments the artificially cured alfalfa was twice as potent in vitamin A as was the field-cured alfalfa. The comparative study of the vitamin E content of these hays was made by comparing the number of litters produced by groups of female rats which received graded quantities …

The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Alfalfa wilt was first discovered in 1924 in southern Wisconsin and northern Illinois. The causal organism, Aplanobacter insidiosum, was later described by McCulloch. Since that time wilt has been reported from most of the alfalfa-growing sections of the United States and in some states it has been responsible for a rapid decrease in the acreage of alfalfa. During the past three years a number of investigators have found that certain alfalfas are somewhat resistant to wilt, whereas others are very susceptible. At the Nebraska station the results to date indicate that all common and most variegated alfalfas are very …

Root System Of Quercus Macrocarpa In Relation To The Invasion Of Prairie, J. E. Weaver, Joseph Cramer

Department of Agronomy and Horticulture: Faculty Publications

Invasion of trees into grassland is primarily a phenomenon of plant competition. It involves the relation of the invaded and the invader to light and other atmospheric factors of the habitat, both physical and biotic. But perhaps even to a greater degree the edaphic factors, and especially water in dry climates, are concerned. Consequently to understand the reasons for plant distribution and the changes resulting from natural successions, a knowledge of the parts of the plants underground and of the interrelations of the root systems is of fundamental importance.

The great tension zone or ecotone between the deciduous forest formation …

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- …

Sporogenesis In Riccia Natans L., Mary Fortunata

Bachelors’ Theses

Until comparatively recent years little, comprehensive Cytological work had been done on the lower forms of plant life including the Liverworts. Cavers (1903) stated that Micheli in 1729 named a species "Hepaticae fontana" because of the supposed resemblance between the branched thallus and the lobes of the liver, and although this species was later named "Fegatella conica", the name "Hepaticae" has, since then, been applied to the whole group of Liverworts. Between 1850 and 1862 Hofmeister demonstrated "Alternation of Generations" in this group, and it was this characteristic that distin­guished them permanently …

The Reaction Of Salts On The Regional Muscular Activity Of The Earthworm, Ernest D. Habeger

Electronic Theses & Dissertations

Though a great amount of work has been done concerning the effects of salts upon the organic constituents of all muscular tissues of the earthworm, very little has actually been accomplished showing the effect of salts on the rhythmic contractions of that animal. However, the normal peristaltic activity of the muscles of the earthworm has been shown to represent a characteristic behavior from its anterior to its posterior extremity.

It is the purpose of this investigation to demonstrate the effects of various concentrations of salts on this normal rhythmic activity of the various regions of the earthworm.

A Study Of Some Species Of Pediastrum And Scenedesmus, Irene Cull

Bachelors’ Theses

Although regarded by the untrained observer as slime, filth and scum, algae are fascinating to the botanist who has become interested in them. Algae are found everywhere; they are our commonest water plants. Among the green algae we have some of the most beautiful and fascinating forms in the plant kingdom and undoubtedly Pediastrum and Scenedesmus, the two genera studied, are among the most beautiful of all.

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 …

Tuber Development In Triumph Potatoes As Influenced By Time Of Planting On Dry Land In Northwestern Nebraska, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Triumph potatoes were planted on four different dates during six years in order to determine the best planting date on dry land in northwestern Nebraska, where this variety is grown primarily for seed. Features considered in comparing the merits of these planting dates were: stand of plants; vine growth; disease prevalence; time of plant maturity; number, size, and shape of tubers; cracking at harvest time; prevalence and severity of common scab; total yields and yields of various grades of potatoes from various harvesting dates; weight loss in storage; and duration of the dormant period. The experimental aspects dealing with the …

The Pituitary, Thyroid, And Adrenal Glands Of The Opossum, Max F. Drozewski

Bachelors’ Theses

In recent years a great deal has been written on the endocrine glands. However most of the articles deal with the physiological function of the various ductless glands only. Very little of this literature deals with the anatomical structure of the organs themselves. In this thesis we shall discuss the anatomical structure of the endocrine glands namely, the Pituitary(hypophysis), Thyroid and the Adrenal of a marsupial. The work has been done on the opossum of the virginia species, Didelphis virginiana. Only two specimens were available for dissection.

General Morphology And Physiology Of The Urogenital System Of The Opossum, Robert Schuster

Bachelors’ Theses

From the very first, I wish the state that the title, "General Morphology and Physiology of the Urogenital System of the Opossum," is not entirely descriptive of the text which is to follow. However it is as nearly descriptive as I could hope to make it.

It seems that during the history of biological research the workers have done comparatively little work on the Opossum. This neglect was probably due to its inaccessibility, since it is found only in Australia and in the semitropic regions of North America. In the nineteenth century the eminent authority on anatomy, Sir Richard Owen, …

Fertilizer Studies As Conducted On The Carbon County Experimental Farm With Special Reference To Treble-Superphosphate, Delos Zobell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1927 an experimental farm was established in Carbon County, Utah. The farm is on a new irrigation tract south of the Price River and about four miles south of Price. The agricultural problems of the Carbon County Experimental Farm and the locality which it serves are distinctly different from those of most of the farming sections in Utah. The soil of this region is of a sandy, silty nature apparently with deflocculated colloids which make it somewhat difficult to manage. There is a low percentage of organic matter in this soil, and because of this and its impervious condition …

Fertilizer Studies As Conducted On Muck Soil In Sanpete County, Utah, Lemoyne Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The reclamation of muck soil is a new development in the state of Utah. Knowledge concerning the various properties and requirements of the newly-drained area in Sanpete County, Utah, is extremely limited. A need for fundamental information concerning this type of soil was the basis for the establishment of an experimental farm in this region. The fact that most organic soils respond to mineral fertilizers soon after they have been reclaimed was an important reason for starting fertilizer work on this soil as soon as it was possible to do so. This thesis reports some of the fertilizer work being …

Alfalfa Seed Production In Millard County, Utah As Related To Soil Type, George Whornham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa has a wide range of adaptability as a forage plant, but the areas in which it will produce seed successfully are extremely limited. These sections are confined almost exclusively to the arid or semi-arid regions of the world. In all other areas it is primarily a question of seasonal fitness. The extreme localization may be further emphasized by the fact that within the highest producing counties there are appreciable areas of land not suitable for seed production.
