Ec44-5-116 Christmas At Wartime, Clara M. Newleee

University of Nebraska-Lincoln Extension: Historical Materials

Should we celebrate Christmas during war times? Why not? Does it help the heartache to sit glumly in the corner and moan? Will this help one or will it help the boy or girl in the service of his or her country? In these war times with all their bad influences and horrible happenings we need to keep up at home every type of mellowing influence and to search out all the inspirational ideals available.

It's fun to make gifts. Much of the joy of Christmas comes in the anticipation and preparation. The making of gifts adds personal touch for …

Effects Of Drought, Dust, And Intensity Of Grazing On Cover And Yield Of Short-Grass Pastures, F. W. Albertson, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

The vast range lands of western Kansas occupy approximately one half of that area. They are now recovering from the terrible destruction wrought by overgrazing, drought, and dust-burial during the past decade. Since grass is man's most powerful ally in soil and water conservation, since pastures are tremendously important as the cheapest and most satisfactory feed for cattle, and since the recovery of the western range is not only an economic problem of great importance but a phenomenon of outstanding ecological interest, the redevelopment of the plant cover warrants careful investigation.

External Parasites Of Poultry And Methods For Their Control, O. S. Bare

Nebraska Agricultural Experiment Station: Historical Circulars

External parasites cause severe losses to Nebraska poultry producers each year, and in many cases may be the deciding factor between success and failure. Under present circumstances, when maximum production is essential, prompt and effective measures must be taken to hold these saboteurs in check.

Controlling Stored-Grain Pests On Nebraska Farms, H. D. Tate, D. B. Whelan

Nebraska Agricultural Experiment Station: Historical Circulars

Warfare against destructive insects is not ended when grain has been placed in the bin. Here it is subject to attack by stored-grain pests which reduce its weight, feeding quality, and value for seed. These losses become especially serious when large stocks of grain are held for extended periods on farms and in warehouses. This circular describes methods available for handling and storage that will prevent or suppress infestations before they reach serious proportions.

The Use Of Dried Whey And Blood Meal In The Raising Of Calves On Limited Amounts Of Milk, I. L. Hathaway, G. W. Trimberger, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The use of substitutes for milk in the raising of calves is always of interest to the progressive dairyman, since there are a number of circumstances in which it is advantageous to reduce the milk feeding period. Producers of market milk often desire to raise their calves on as little milk as possible in order to have more milk available for market. When the demand for milk is good, dairymen who usually market cream only may prefer to sell milk and raise their calves on starters or other milk substitutes. Dairy farmers may wish to use the skim milk generally …

Replacement Of True Prairie By Mixed Prairie In Eastern Nebraska And Kansas, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Destruction of a portion of one plant association and its replacement by another has just been completed. This has occurred not as the result of man's interference with the vegetation nor the effect of his grazing animals. It has been due to a dry climatic cycle and has been accomplished within a period of seven years. The scene of action was the broad area on the western edge of true prairie in central Kansas, eastern Nebraska, and eastern South Dakota. It is distinctly east of the mixed prairie in the central portion of these states. Although the phenomenon was general …

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to present the data on nitrate contents and nitrate production in tests where straw or stalk residues were left on the surface through subsurface tillage, as compared with check treatments where these residues were plowed under or were absent. Nine of these tests were at Lincoln, Nebraska, and one was at the Hastings, Nebraska, Hydrological Project. Two tests were conducted in 1939, four in 1941, and four in 1942.

Bindweed Eradication In Nebraska, N. S. Hanson, F. D. Keim, D. L. Gross

Nebraska Agricultural Experiment Station: Historical Circulars

Bindweed, which is easily recognized by its creeping, entwining habit of growth, is Nebraska's most destructive weed because of its effect on crop plants. Its total annual cost to the agricultural industry of the state is several million dollars, which ultimately affects all those citizens who depend directly or indirectly upon income from agriculture.

Fishes Of The Middle West, Rachel L. Carson

United States Fish and Wildlife Service: Publications

The waters of the Mississippi River and the Great Lakes are a potential source of several hundred million pounds of food in the form of tasty lake and river fishes. This rich resource of the inland waters is important to a nation at war. Because of the growing meat shortage, people will eat more fish than in pre-war years. In the interior of the country, people will eat more fresh-water fish than before, because fish are good and nutritious and because, in the coming months, the shipments of rosefish, halibut, shrimp, and other seafoods that come to them from the …

The Outlook For Waxy Sorghum In Nebraska, R. L. Cushing

Nebraska Agricultural Experiment Station: Historical Circulars

This circular reports on the present situation regarding the use of waxy sorghum grain for the manufacture of special starches. In the spring of 1942, a publication from this Station (Experiment Station Circular 69) suggested the possibility of a market for the waxy grain of Nebraska-grown Leoti sorgo. Since then there have been many developments which may interest those who have grown or who may contemplate growing Leoti in Nebraska.

Conception Rate In Dairy Cattle By Artificial Insemination At Various Stages Of Estrus, George W. Trimberger, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A breeding experiment with 295 dairy cows and heifers of the Jersey, Guernsey, Ayrshire, and Holstein breeds was conducted in the University of Nebraska dairy herd. The females were given artificial services at various stages of estrus to determine the effect of time of service upon conception. The results obtained indicate the potential benefits in higher percentage of conception in females bred during the middle of estrus, toward the end of estrus, and those bred in full heat and rebred in 24 hours. The latter is usually not very practical, especially in artificial breeding rings, but there are occasions when …

Cockroach Control, H. D. Tate, E. C. Klostermeyer

Nebraska Agricultural Experiment Station: Historical Circulars

Cockroaches are among the most annoying and objectionable of household pests. They are a menace to sanitation, and their filthy habits result in the destruction and pollution of food. Not only may they become numerous in homes, but also in restaurants, hotels, grocery stores, dairies and other places where food is prepared or stored. Since they are active mostly at night, large numbers may develop in a building before they are known to exist.

Food From The Sea: Fish And Shellfish Of New England, Rachel L. Carson

United States Fish and Wildlife Service: Publications

Millions of Americans are developing new wartime food habits, trying foods they once neglected, turning to alternates for long familiar products. For everyone of the ten fish or shellfish that make up mere than four-fifths of New England's catch there are seven species little known or utilized, many of which could provide tasty and nutritious foods. Turning to these under-utilized species will conserve food resources by lifting the burden of over-exploitation from such fishes as cod and haddock and will augment dwindling supplies of protein foods. Exploring the seafood markets for unfamiliar species rewards the housewife and her family with …

Effect Of Manganese And Iodine Additions In A Specific Ration For Laying Hens, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

This preliminary experiment does not answer all of the questions that are presented about manganese and iodine requirements. It can only be taken to indicate that for a typical situation with a typical ration of the type that many poultry producers use, there was no satisfactory evidence that egg production, hatchability and the viability of the hens was limited by manganese and iodine in the ration.

Increases In Aphid Populations On Potato Plants Sprayed With Zinc Arsenite In Western Nebraska, Roscoe E. Hill, H. Douglas Tate

Department of Entomology: Faculty Publications

During the 1941 growing season, field observations in western Nebraska indicated that aphids, Myzus persicae (Sulz.), were becoming abundant in experimental potato plots that had been treated with zinc arsenite-lime sulfur spray for controlling potato flea beetles, Epitrix cucumeris (Harr.), and the potato psyllid, Paratrioza cockerelli (Sulc.). Detailed examinations of leaves showed that significantly greater populations were present on the sprayed than on the untreated plants. Evidence of slight increases also was noted on plants dusted with a barium fluosilicate and sulfur mixture.

Nebraska Cattle Grub Survey, Lewis T. Graham, H. Douglas Tate

Department of Entomology: Faculty Publications

The scarcity of data on the actual extent of cattle grub infestation in Nebraska became evident during the winter of 1942--43 when a control program was being organized. Although there were some cattlemen who were acutely aware of the losses occasioned by this pest, there were many others who had given the problem little thought or who believed that infestation resulted largely from the importation of feeder cattle. More detailed information was obviously desirable in order to present an accurate and convincing account of the problem to the cattle growers.

The Occurence Of The Potato Tuber Worm In Nebraska, H. Douglas Tate

Department of Entomology: Faculty Publications

A sample of potatoes showing tuber worm injury was submitted to the Entomology Department by a farmer of Elmwood (Cass County), Nebraska in September 1939. A few days later the farm was visited and a bin of about 125 bushels of potatoes was found to be heavily infested with the potato tuber worm. In compliance with instructions, the grower either used or destroyed the entire crop during the early part of the ensuing winter. Potato fields in the same vicinity were examined the following year, but no specimens or evidence of injury by this pest could be found. Apparently, this …

Studies On Restaurant Sanitation And The Effect Of Sodium Azide On The Physiology Of Streptococcus Salivarius, Kenneth D. Rose

Open Access Master's Theses (through 2010)

Whether restaurant eating utensils serve as vectors in the transmission of respiratory and related diseases is still a matter for question, in spite of the overwhelming evidence in support of this contention.This is due to largely to the lack of epidemiological evidence, the tracing of an outbreak of a disease directly and unquestionably to contaminated eating utensils.The very nature of the vectors concerned obviates any possibility of obtaining this epidemiological evidence, since the contaminating agent exists as such only momentarily at the best. This research problem was undertaken with the hope that a technique designed to demonstrate the appearance of …

Resurvey Of Grasses, Forbs, And Underground Plant Parts At The End Of The Great Drought, J. E. Weaver, F. W. Albertson

Department of Agronomy and Horticulture: Faculty Publications

Eight years have now passed since the fateful spring of 1934. The almost rainless March and April, the unusually high winds, and the great clouds of dust following two summers of decreasing precipitation, portended disaster. The intensity and duration of the drought and its appalling destruction have been studied from the beginning (Weaver, Stoddart, and Noll 1935) and several reports have recorded changes wrought in the native grass cover (Savage 1937; Weaver and Albertson 1936, 1939, 1940, 1940a). Drought began in great intensity a year earlier in the mixed prairie westward and south-westward. But previous to 1933, intensive studies had …

Use Milk - An Essential Food, University Of Nebraska - Lincoln

Nebraska Agricultural Experiment Station: Historical Circulars

The purpose of this publication is to furnish the housewife with information on ways to utilize more milk in the home, especially in the farm home where milk is readily available and an economical source of vitality and greater health for all the family.

Relative Drought Resistance Of Seedlings Of Dominant Prairie Grasses, Irene Mueller, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Recent study of the severe damage to native midwestern grasslands resulting from the great drought was fundamentally an investigation of drought resistance of the various species of dominant grasses and accompanying forbs (Weaver and Albertson, '39, '40). Studies extending throughout the entire eight- or nine-year period of drought, especially those concerned with recharting permanent plots, have resulted in an accumulation of evidence regarding relative drought resistance of the various species (Albertson and Weaver, '42). Extensive field studies on the role of seedlings in recovery of midwestern ranges from drought have added much information on this subject (Weaver and Mueller, '42). …

Swine Erysipelas Infection In Man, L. Van Es

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The preceding decade witnessed the introduction and spread within this state of a hitherto uncommon disease of swine. This disorder, swine erysipelas, has gradually become disseminated throughout Nebraska's swine population until it has developed into a major problem of preventive veterinary medicine. Its appearance, furthermore, added another to our list of animal maladies which are communicable to man. The latter consideration may serve as warrant to review what is known about the part played by swine erysipelas as a human disease, to describe its more salient features and to examine them from epidemiological, clinical, pathological and prophylactic viewpoints.

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead

Conservation and Survey Division: Faculty and Staff Publications

Agricultural practices in the Great Plains of North America are now in a period of adjustment from a traditional agriculture initiated by pioneer farmers to a grazing economy based upon potentialities of climate and soil. The attainment of a proper system of land use has been retarded in many localities by the lack of definite information concerning the vegetation and its indicator significance. In this study of the vegetation of Cherry County, Nebraska, the interrelations between the plants and their environments are discussed, the dominant species are described, and changes in grasslands caused by seasons, grazing, and climatic cycles are …

Role Of Seedlings In Recovery Of Midwestern Ranges From Drought, J. E. Weaver, Irene Mueller

Department of Agronomy and Horticulture: Faculty Publications

An extensive survey of the degree of deterioration of midwestern ranges was made in 1939 (Weaver and Albertson, '40). Decreases in the basal cover of the grasses from extreme drought, overstocking, and damage by dust were appalling. Basal cover of the native grass had decreased to 1 percent in one-fourth of the ranges examined and it was 21 percent or more in only 16 percent. Little, if any, improvement occurred during the following year; instead certain large areas suffered distinct losses as a result of severe late summer drought. The perennial grasses over large areas in southwestern Kansas, for example, …

Forest Sequences In The North Central State, Paul B. Sears

Papers in Ecology

This paper presents fifteen pollen profiles from as many peat deposits in Illinois, Indiana, Michigan, and Ohio, only two of which--Bucyrus and Mud Lake (Ohio)--have been previously published. These profiles have been prepared to show only the relative fluctuations of eight forest genera and one family, Betulaceae.

Alfalfa Breeding, H. M. Tysdal, T. A. Kiesselbach, H. M. Westover

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Interest in the principles of alfalfa breeding has increased greatly with the growing "forage consciousness" of the country at large and the more specific interest developed through cooperation in the Alfalfa Improvement Conference. As is true of many other forage crops, information on the breeding behavior of alfalfa is meager. During the past few years, however, the genetics and principles of reproduction of this crop have come to be better understood and it is the purpose of this paper to bring together the available information pertaining to the improvement of alfalfa and to add certain suggestions with respect to future …
