Stem Rust In Nebraska. Part I. General Survey Of Sources. Part Ii. Identification Of The Physiologic Forms Of Puccinia Graminis From Various Sources, George L. Peltier, A. F. Thiel Jul 1927

Stem Rust In Nebraska. Part I. General Survey Of Sources. Part Ii. Identification Of The Physiologic Forms Of Puccinia Graminis From Various Sources, George L. Peltier, A. F. Thiel

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Part I: Since the inception of the barberry eradication campaign in 1918 in Nebraska, the question has continually been asked, "Will the eradication of the barberry in the state eliminate or materially reduce stem rust?" In order that an answer might be obtained, an investigation to determine the sources of primary infection of stem rust on cereals was inaugurated in the spring of 1921. Although these studies have been carried on for 6 years, no definite statement regarding the relative importance of the primary sources and the amount of stem rust prevalent in the state from season to season originating …

Circular No. 66 - Physical Curd Character Of Milk And Its Probably Relation To Infant Nutrition, R. L. Hill Jun 1927

Circular No. 66 - Physical Curd Character Of Milk And Its Probably Relation To Infant Nutrition, R. L. Hill

UAES Circulars

A problem which must be met by many mothers is that of obtaining for their infants an adequate substitute for breast milk. The weaning period is a very critical time in the life of every infant. Its ability to properly digest and assimilate the food supplied will largely determine its state of health, provided it is kept free from infection.

Milk formulas for the feeding of infants are often made up to conform to certain fat requirements. Some infants apparently have difficulty in properly assimilating a milk with a high fat content. This may be due to a low fat …

Circular No. 67 - Rules And Regulations For The Fourth Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

This contest is conducted on a part of the Utah Agricultural College Farm near the experimental poultry yards. It is managed by the Poultry Department with an experienced poultry raiser in direct charge of the feeding and care of the hens in the contest. The buildings, grounds, and fences were built and furnished by the Experiment Station.


Bulletin No. 202 - Some Observations On Winter Injury In Utah Peach Orchards, T. H. Abell Jun 1927

Bulletin No. 202 - Some Observations On Winter Injury In Utah Peach Orchards, T. H. Abell

UAES Bulletins

During the winter following the freeze, fruit growers in Utah were deeply concerned over the effects of the cold on their orchards, since it was observed that not only were fruit buds killed, but the tissues of the trunks, limbs, and twigs were turning brown. The question at once arose as to whether or not this browning indicated the approaching death of the trees. It was, therefore, considered important to determine, if possible, the nature and extent of the damage, to discover any factor which might have favored or lessened the injury, and finally to offer suggestions to the orchardist …

The Development Of The Gametophyte And Apogamous Sporophyte In Cheilanthes Feei, Moore, Florence Madeline Steil Jun 1927

The Development Of The Gametophyte And Apogamous Sporophyte In Cheilanthes Feei, Moore, Florence Madeline Steil

Bachelors’ Theses

Since Leszeye-Suminski's (1848) discovery of tracheids near the apical notch of the prothallium of Pteris sulcata, problems pertaining to apogamy or related phenomena have offered a wide field for botanists. Nearly all workers interested in the study of apogamous ferns, have contributed something of physiological or cytological interest


Some Methods Of Vegetative Reproduction In Nephrolepis Cordifolia, Presl, Mildred Frances Hubel Jun 1927

Some Methods Of Vegetative Reproduction In Nephrolepis Cordifolia, Presl, Mildred Frances Hubel

Bachelors’ Theses

Nephrolepis cordifolia, Presl is reproduced by means of spores, rhizomes, runners, and tubers. Little work has been done, however, on the tubers. In fact, the tubers are generally thought to be for storage only and consequently of little importance. At the Royal Palm Nurseries, Oneca, Florica where the plants for this study were obtained, the tubers were removed and thrown away. When a request was made for a large plant with the tubers, they replied: "We cannot supply the large cordifolia with the bulbs, as they were pruned off all our plants. They do not present a very attractive appearance …

Bulletin No. 200 - Maintaining Potato Yields By Hill Selection, George Stewart, D. C. Tingey May 1927

Bulletin No. 200 - Maintaining Potato Yields By Hill Selection, George Stewart, D. C. Tingey

UAES Bulletins

Utah's agriculture has passed definitely out of its pioneer period. Single-cropping, whether to wheat, to potatoes, or to sugar-beets, during the past few years has been forced from its last stronghold. The earmarks of mature agriculture are already visible. Of these, there are four important ones: (1) the production of both crops and livestock; (2) careful manuring and irrigation; (3) good crop rotations; and (4) the use of high-grade parental stock, that is, prepotent sires for livestock and strong and healthy seed for crops.


Bulletin No. 199 - Mutual Irrigation Companies In Utah, Wells A. Hutchins May 1927

Bulletin No. 199 - Mutual Irrigation Companies In Utah, Wells A. Hutchins

UAES Bulletins

Cooperation has been an important factor in the development of agriculture under irrigation in Utah. The Mormon pioneers in the Great Basin were the first Anglo-Saxons to practice irrigation on an extensive scale in the United States; hence, it is significant that from the first their irrigation work was accomplished largely as a result of community effort. Private diversions of water there were, of course, even in the earliest times, but for years they were quite out of place in an environment that took quick toll of those individualists who scorned the protection of numbers and refused to cooperate. The …


Further Experiments With Poisoned Baits For Grasshoppers, M. H. Swenk May 1927

Further Experiments With Poisoned Baits For Grasshoppers, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In the summer of 1922 a series of experiments was carried on at the Scotts Bluff Experiment Substation for the purpose of finding, if possible, a formula for preparing an inexpensive and efficient poisoned bait for grasshoppers that could be recommended to the farmers of the North Platte valley, and also of learning more concerning the relative values of certain attractants and poisons commonly used in such baits, as well as the best time to scatter them to obtain the most satisfactory results. While the results were fairly conclusive from a qualitative standpoint, the time was not available in the …


A Study Of The Seasonal History Of Alfalfa Flowers As Related To Seed Production, John W. Carlson May 1927

A Study Of The Seasonal History Of Alfalfa Flowers As Related To Seed Production, John W. Carlson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A few researches have been concerned with the structure and pollination of alfalfa flowers. Others have considered the biological problems concerned in the pollination and fecundation of the flowers. In none of these studies, however, has an attempt been made to follow carefully the alfalfa flowers through various stages of development. Nor has any effort been made to determine what effect the condition and duration of these stages may have upon the resulting seed crop.

The work that follows is a study of the changes through which the alfalfa flowers pass during the season while functioning as organs of seed …


Distributional List Of The Birds In Utah, Clarence Cottam May 1927

Distributional List Of The Birds In Utah, Clarence Cottam

Theses and Dissertations

Systematic ornithology has been woefully neglected in Utah. While this state has a number of men who know her birds and who have aroused interest in them, they have produced no published record of what we have. So far as the writer knows there is no adequate, representative, or systematic collection of Utah species within the state. Utah has, however, been fortunate in having a nuraber of expert ornithologists collect and study the bird life of different sections of bar territory.


Bulletin No. 201 - Economic Insects In Some Streams Of Northern Utah, James G. Needham, Reed O. Christenson Apr 1927

Bulletin No. 201 - Economic Insects In Some Streams Of Northern Utah, James G. Needham, Reed O. Christenson

UAES Bulletins

The food of trout in our mountain streams is mainly insects. It is, in part, land insects that fall on the water and are taken as they float upon its surface, but in a much larger part it is insects that grow up in the water and are taken in their immature stages. These are the constant and dependable food-supply. They have been little studied hitherto. This bulletin is a report of a preliminary examination of some Utah streams, made for the purpose of discovering what forms of life are present in the streams and in what relative abundance. Some …

The Pine Tipmoth In The Nebraska National Forest, M. H. Swenk Apr 1927

The Pine Tipmoth In The Nebraska National Forest, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

On May 8, 1911, Mr. Smith Riley, the District Forester, with headquarters at Denver, in a letter to Acting Supervisor Pierce at Halsey, requested that the Nebraska Agricultural Experiment Station take up energetically the investigation of the pine tipmoth in the Nebraska National Forest. This request being presented to the Department by Mr. Pierce later in the month resulted in the presentation of the problem to the Experiment Station Council as a proposed Station project. The project was approved on May 31, 1911, and the expenses of the investigations of 1911 and 1912 that are reported upon in this bulletin …


Babcock Testing - Principles And Uses, L. K. Crowe, H. P. Davis Apr 1927

Babcock Testing - Principles And Uses, L. K. Crowe, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

The manufacturing of dairy products on a commercial scale began about the middle of the nineteenth century and was greatly stimulated by the development of the centrifugal cream separator in the late eighties. The invention of the Babcock test in the early nineties overcame some of the difficulties that had developed in paying for milk upon its butterfat content, since it was early recognized that milk varied widely in that respect.


Crop Production In India, J. E. Weaver Apr 1927

Crop Production In India, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

It is rarely that one finds a book on the subject of agriculture of such broad scope, fascinating interest, and so full of the applications of ecology and physiology as Howard's " Crop-production in India." In every chapter numerous problems of plant growth in relation to environment are brought before the reader in such a stimulating manner that one can scarcely conclude but that ecology will reach its greatest usefulness in the field of general agriculture. It is a book to which every student of environment should have ready access.

Ec27-811 Harvesting Wheat In Nebraska With The Combined Harvester Thresher 1926, Arthur G. George Jan 1927

Ec27-811 Harvesting Wheat In Nebraska With The Combined Harvester Thresher 1926, Arthur G. George

University of Nebraska-Lincoln Extension: Historical Materials

Frequent inquiry from wheat growers in Nebraska and others as to the relative merits of the combined harvester-thresher as an efficienct and economical harvesting machine led the Nebraska Agricultural College to make a study of this problem in the summer of 1926. The work was carried on by the Departments of Rural Economics and Agricultural Engineering, cooperating with the United States Department of Agriculture which was conducting a similar survey in different parts of the United States. Perkins county, Nebraska, was the area selected for study as it is more or less typical of those parts of the state where …
