The Development Of The Gametophyte And The Apogamous Sporophyte Of Pteris Quadriaurita, Var. Argyraea, Moore, Anno Mary Sendik

Bachelors’ Theses

In 1.848 Leszczyc-Suminski reported the appearance of sporophyte tissue element in a fern gametophyte. He observed tracheids near the apical notch of a prothallium of Pteris sulcata L. Wigand (1849) described an outgrowth from the apical notch of a fern prothallium. This was no doubt the development of an apogamous embryo. However, due to the uncertainty regarding the purity of some of his cultures, this development cannot be referred to any particular fern.

Bachelors’ Theses

Picea excelsa, Link is a native of middle and southern Europe, it has been transplanted to all cool climates, it is found plentiful in western North America, and thrives best in rural districts, away from the smoke and gas of the city.

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 …

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.

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.

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.

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 …

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.

Circular No. 83 - Planning, Planting, And Caring For Young Orchard, Francis M. Coe

UAES Circulars

Fruit growing offers many advantages to the farmer of the intermountain west, chief of which is the high return possible from a relatively small farm. Few crops will give as high an acre-yield or return as a properly located and managed orchard. Acre-yields of from 500 to 800 bushels of apples, pears, or peaches are not unusual. The work is pleasant, interesting, and healthful, as well as remunerative when properly conducted. Fruit Growing Attractive, Profitable

The Anatomy Of The Germinating Bulbil Of Lilium Tigrinum, Katherine Harris Tripp

Electronic Theses and Dissertations

Apparently very little, if any, anatomical investigation has been made of the bulbil of Lilium tigrinum, though it has often been used as a propagating organ and consequently, the problem suggested attractive possibilities in an almost virgin field of investigation. Collections were made from five different plants beginning Sept. 27, 1928 until July 22, 1929. The older bulbils were removed from the axils of the foliage leaves and fixed in formalin acetic alcohol. They were gradually dehydrated by treatment with alcohol increasing the percentage 10% from 50 up to 100%. Xylol treatment in increasing percentages was then resorted to, until …

Leaflet No 256 - Climbing Cut-Worm Or Tomato Moth (Chlorodea Obsoleta), L. J. Newman

Bulletins 1 - 2999

During the past spring caterpillars of various kinds have been unusually prevalent. In some instances they have been so numerous as to constitute a plague.

The caterpillar most in evidence was the larva of the Climbing Cut-worm or Tomato Moth.

Propagation Of Aquatic Game Birds, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The propagation of aquatic game birds in the United States is a small but growing industry. Approximately 50,000 wild ducks and 5,000 wild geese constitute the present annual production. Some of these birds are bred by individual or organized sportsmen for their own use, some by fanciers because of their interest in the birds, and others by breeders for sale. The market for two species, the mallard duck and the Canada goose, demands birds for use in restocking, for decoys, and for food. Sale for food is the exception rather than the rule, and is to the better class of …

Abortive Stamens And Carpels In Lychnis Alba, Gus B. Ulvin

Electronic Theses and Dissertations

Botanists have long been interested in the manner of "sex expression" in plants. Some plant shave perfect flowers, that is, both sexes are expressed in a single flower, with no variation from this condition within the species. Other plants have flowers in which only one or the other sex is expressed, while still other plants occur in which "pure staminate or pure carpellate and all intermediate degrees" occur.

Homes For Birds, E. R. Kalmbach, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Birds appeal strongly to the interest and affection of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.

Birds feed upon practically all insect pests. They are voracious, able to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.

For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their numbers. …

Alfalfa Production In A Grassland Climate, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

The importance of root extent and activities in relation to the supply of subsoil moisture has again been clearly demonstrated. In fact, it has been shown to be the chief problem in the continued production of alfalfa in a grassland climate.

Studies extending over a period of 15 years have shown that the native species of the tall-grass prairie never exhaust the water supply below that available for plant growth, except rarely in the shallower soil. The subsoil is always moist, and plants root deeply. Of 43 species typically representative of the flora, only 14 per cent absorb almost entirely …

Relation Of Increased Water Content And Decreased Aeration To Root Development In Hydrophytes, J. E. Weaver, W. J. Himmel

Department of Agronomy and Horticulture: Faculty Publications

The dependence of root development of most plants upon aeration is clearly shown by water-logging the soil. In a few days, the usual cultivated plants turn yellow, show wilting, and may ultimately die. If the water is kept well aerated, plants may survive though submerged for weeks. Exclusion of oxygen from the roots of most plants interferes with the respiration of the protoplasm of their cells. This results in the death of the cells and consequently the roots fail to function as absorbers for the plant (22).

Seed Potato Treatment Tests For Control Of Scab And Rhizoctonia, R. W. Goss, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Potato scab annually takes a very large toll from the potato growers of Nebraska. Rhizoctonia causes considerable loss each year, particularly in the early-potato sections, where it decreases stand and yield. These losses are caused by infection from both the soil and the seed. The investigations reported in this paper deal only with the control of the infection arising from the seed. Even though potato seed treatments have been recommended for many years, the diversity of recommendations being made at present by various agencies is very confusing to the grower and research worker alike. Many of the reports from different …

Effect Of Cultural Methods And Maturity Upon The Seed Value Of Eastern Nebraska Potatoes, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Seed potatoes as good as northern stocks have been produced under a straw mulch in eastern Nebraska by experimenters and growers. Occasionally reports are heard that a lot of seed potatoes has been grown in eastern Nebraska by ordinary cultural methods for many years, apparently without loss of vigor or yielding capacity. In view of this situation it seemed advisable to investigate this problem to determine whether, and to what extent, environment and maturity as such influence the productivity of seed potatoes and also whether it is feasible to produce satisfactory seed potatoes in the southern and eastern portions of …

Circular No. 82 - Lamb Slaughtering And Cutting, Harry H. Smith

UAES Circulars

The old saying that "the shoemaker's wife goes without shoes" might be changed to read "the lamb raiser and feeder of the west does not eat lamb." About three-fourths of the population of the United states is east of the Mississippi River, and about 90 per cent of all the lamb and mutton produced in the United states is consumed east of the Mississippi. It has been observed, both on the farms and in towns, that a large percentage of people in the sheep sections of the west have tasted neither lamb nor mutton.

Circular No. 81 - Beef Slaughtering, Cutting, And Curing, Harry H. Smith

UAES Circulars

Many farmers follow the practice of occasionally slaughtering a steer, a heifer, or a calf for home use. When this practice is followed the farmer is assured of getting meat of high quality. Experience has taught him that he is not always :able to get meat at a local market which equals in quality that which he slaughters on his own farm. The butcher is not at fault as he usually handles the quality of meat his customers desire and will accept.

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.
