Spraying Tree Fruits, C. C. Wiggans, E. H. Hoppert

Nebraska Agricultural Experiment Station: Historical Circulars

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Ec28-234 Nebraska System For Tattooing Hogs For Identification After Slaughter, G.R. Boomer, O.O. Waggener

University of Nebraska-Lincoln Extension: Historical Materials

A plan to identify the individual farm upon which hogs reaching markets are produced has been developed in connection with the efforts toward eradicating tuberculosis among farm animals. While primarily intended as a means of tracing back to determine sources of disease infection, the system of tattooing which is being developed has other significant possibilities. With the growing emphasis on quality products in the market, it is only fair that the producers of high quality commodities receive the premiums paid by processors and consumers. Health of farm animals is a quality factor. The producer of healthy hogs should be rewarded. …

Ec28-36 Spraying Tree Fruits (Revised March 1932), C.C. Wiggans, E.H. Hoppert

University of Nebraska-Lincoln Extension: Historical Materials

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Spray materials, equipment, management, schedules, insect pests and orchard diseases are discussed in this 1928 extension circular.

Rb28-229 Fattening Steers Of Various Ages, H.J. Gramlich

University of Nebraska-Lincoln Extension: Historical Materials

During recent years the beef industry has undergone vast changes. These have been made necessary in part by economic conditions and in part by changes in the demands of the American people. The tendency has been toward earlier marketing of steers, so that instead of going to the block as mature individuals at from 3 to 5 years of age, they are now reaching the market at a much younger age. In consuming centers where only heavy carcasses of beef were demanded formerly there is a call today for carcasses of the yearling and long yearling class.

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 …

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 …

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

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.

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 …

The Immediate Effect Of Gametic Relationship And Of Parental Type Upon The Kernel Weight Of Corn, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This investigation to determine the relation of the kernel weight of corn to the source of pollen with which it was fertilized has been made to answer several questions of both practical and technical interest: (1) To what extent is kernel weight affected in the current crop by the "breadth of breeding" or the gametic relationship? (2) What is the relation of the diversity of parental type to the immediate effect of foreign pollen upon the kernel weight of corn? (3) Is the immediate effect of cross-fertilization upon the kernel weight of sufficient importance to justify the annual mixing of …

The Differential Reaction Of Strains Within A Variety Of Wheat To Physiologic Forms Of Puccinia Graminis Tritici, T. A. Kiesselbach, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Black stem rust of wheat (Puccinia graminis tritici (Pers.) Erikss. & Henn.), which occurs in Nebraska and thruout most of the wheat producing regions of the world, is of a composite nature, in that it consists of a number of physiologic forms which can be determined by their action on different varieties of Triticum species, as shown by Stakman and Levine. The ordinary commercial variety of wheat may likewise be regarded as a mixture, in that it consists of numerous strains, which differ in some more or less important characteristics, as has been frequently indicated in the literature concerning …

Nutrient Requirements Of Growing Chicks, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of our experimental work was to establish if possible certain principles of poultry nutrition, permitting later a better combination of natural feedstuffs with the highest growth efficiency.

Alfalfa Investigations, T. A. Kiesselbach, Arthur Anderson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of these alfalfa investigations has been to determine the relation of variety, source of seed, and cultural practice to the yield and quality of hay produced. Due to the high initial cost of seeding, the inconvenience and wastefulness of losing a stand prematurely, and the superiority of properly-made hay, an understanding of these relationships is very important.

Studies On The Ascaris Lumbricoides, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The Ascaris lumbricoides, in one phase or another, has attracted the attention of parasitologists for many years, and during the last decade this parasite has been studied by a large number of investigators. The recent observations have been, to a great extent, directed along one line, the study of its life history. These investigators have established two important points: (a) That the life history of Ascaris is more complex than was supposed, as it has been found that a vasculo-pulmonary circuit of the larvae is necessary before they settle down in the intestine, where they develop to the adult …

Studies On The Ascaris Lumbricoides, Harry Mathias Martin

University of Nebraska-Lincoln Extension: Historical Materials

The Ascaris lumbricoides [roundworm], in one phase or another, has attracted the attention of parasitologists for many years, and during the last decade this parasite has been studied by a large number of investigators. The recent observations have been, to a great extent, directed along one line, the study of its life history. These investigators have established two important points: (a) That the life history of Ascaris is more complex than was supposed, as it has been found that a vasculo-pulmonary circuit of the larvae is necessary before they settle down in the intestine, where they develop to the adult …

Turkey Production, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Whatever problems turkey production presents, lack of demand for roast turkey is not at this time one of them. Turkeys rate so high in popular esteem that very rarely indeed do prices fall below that of dressed chickens and usually the best grades are 12 to 15 cents per pound higher during the holiday season. The world of commerce has become quite complex but the consuming public still has one clear way of speaking to producers. In the language of the dollar we are apparently being asked to raise more turkeys.

The Spindle-Tuber Disease As A Factor In Seed Potato Production, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The lines of experimentation that supplied the data herein reported, stated in very general terms, were as follows: (1) Tuber-line selection studies (2) Relation of environmental conditions to seed-potato production (3) Seed-potato strain trials of certified and uncertified stock (4) Spindle-tuber transmission experiments. Most of these general lines of experimentation will not be completely discussed as a unit in any one part of the bulletin. For the sake of clarity, consecutive thought, and elimination of repetition, data will be selected from any experiment for insertion and discussion under the most logical heading in any part of the bulletin. Unless otherwise …

Ec26-129 Profitable Wheawt Production, P.H. Stewart, D.L. Gross

University of Nebraska-Lincoln Extension: Historical Materials

More profitable wheat production, rather than greater total production in Nebraska, is the object of this circular. The grower who has the largest acreage of wheat does not necessarily make the greatest profit. High yields per acre usually means a lower cost and a great profit per bushel. Wheat of high quality brings additional profits. High yield and quality are usually the combined result of good seed, disease prevention, crop rotations, a well-prepared seed bed, the proper time of seeding, and reasonable care in harvesting, threshing and storing.

A Study Of The Environmental Conditions Influencing The Development Of Stem Rust In The Absence Of An Alternate Host. Iv. Overwintering Of Urediniospores Of Puccinia Graminis Tritici. V. The Period Of Initial Infection Of Urediniospores Of Puccinia Graminis Tritici On Wheat. Vi. Influence Of Light On Infection And Subsequent Development Of Urediniospores Of Puccinia Graminis Tritici On Wheat, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

IV. In order to ascertain whether the urediniospores of Puccinia graminis tritici (Pers.) Erikss. and Henn. overwinter under the environmental conditions prevailing at Lincoln, Nebraska, a series of experiments was carried out extending over a period of 5 years. The results of this investigation are briefly presented. V. By the period of initial infection is meant the time required by a pathogen after it reaches a susceptible plant part to enter the tissues. To determine what the period of initial infection of urediniospores of Puccinia graminis tritici might be, experiments were undertaken during the season of 1923-24 using urediniospores of …

Winter Wheat Investigations, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Twenty years of wheat breeding, consisting chiefly of the isolation and testing of pure lines, has now been conducted at the Nebraska Agricultural Experiment Station. It is the purpose of this paper to report the conduct and results of this work. The resulting strains are compared with the best other wheats available from Nebraska and other sources. The effects of a number of cultural practices related to the preparation of seed, seeding, treatment of the growing crop, and harvesting are also presented. Some consideration is given to the experimental technique of the comparative tests.

Better Rations - More Eggs, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Well-bred and well-fed hens are conceded to be economical producers of a very wholesome food product, eggs, but our hens are not miracle workers and they insist on the right kind of raw material for building the egg. Nebraska poultry growers fortunately have all the natural feeds - corn, wheat, oats, barley, and dairy and packing house by-products - readily available at lower cash prices than prevail in most other states, and so our special problem is that of combining them so that eggs may be produced at the lowest cost per dozen.

A Study Of The Environmental Conditions Influencing The Development Of Stem Rust In The Absence Of An Alternate Host. Iii. Further Studies Of The Viability Of Urediniospores Of Puccinia Graminis Tritici, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The influence of relative humidity and temperature on the viability of the urediniospores of two Physiologic Forms of Puccinia graminis tritici has been determined. 2. The same general relation between the viability of the urediniospores and the relative humidity and temperature was found, namely, that the lower the temperature the longer the spores retained their viability at all relative humidities, while at any stated temperature the spores were viable the longest at the medium humidities. 3. Urediniospores of Physiologic Form XXI held at 49.0 per cent relative humidity and maintained at a temperature of 5° C. when tested for …

Hardy Alfalfa For Nebraska, T. A. Kiesselbach, A. Anderson

Nebraska Agricultural Experiment Station: Historical Circulars

Comparative tests of varieties and regional strains of common alfalfa at the Nebraska Experiment Station have clearly indicated that winter hardiness is an important factor to be considered when purchasing alfalfa seed. Much of the seed sold in the United States has proved inferior in this regard for Nebraska conditions. The use of southern-grown domestic seed or seed imported from countries with a much milder climate than that of Nebraska should be avoided in this state. On the other hand, reliance may be placed on the seed of hardy varieties or hardy regional strains of common alfalfa grown in Nebraska …

Selection, Breeding, Methods Means More Milk, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Milk good cows. It pays if you know how. Good dairy cows will always make money. Scrub, poor, or common cows never bring a good profit and usually cause a loss. Why waste feed and labor on inefficient producers, the kind that never make a satisfactory profit? Join a cow testing association. Let the tester keep books on your cows and let the milk scale and the milk sheet point out the money makers. Improvement comes only from selection and breeding.

Feeding The Dairy Cow, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Cows produce milk from feed and water only. Therefore feed in proper quantity and quality is usually the limiting factor governing a cow's production up to the limit of her capacity.

Dairy Calf Care And Management, H. P. Davis, R. F. Morgan

Nebraska Agricultural Experiment Station: Historical Circulars

Calf raising begins before the calf is born. A cow that is healthy and in good physical condition will, in all probability, drop a strong, vigorous calf. The feeding and care of the cow before calving is therefore of the greatest importance for the future development of the calf.

The Chinch Bug And Its Control, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Circulars

During the last half century there have been five separated and well-marked chinch bug outbreaks, or periods of serious damage, in Nebraska, and we are now approaching the climax of a sixth such period. As to just how serious this present outbreak will be in 1925 no one can now say, because no one can exactly forecast the weather conditions of the summer, but the present situation is sufficiently menacing to make advisable the issuing of this circular, which aims to give the essential information concerning the chinch bug as a Nebraska pest, and the locally applicable means of control.

Tuberculosis Of Swine, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

The tuberculosis of swine constitutes a definite and very interesting section of the general problem of the tuberculoses of warm-blooded animals. No one section of this general tuberculosis problem can be adequately solved without regard to all the other sections into which it may be divided. The disease in swine is perhaps the most outstanding example which illustrates this point. This animal, extremely susceptible to tuberculous disease, but without a type of infection specifically its own, derives its infection by contact with any of the types of tuberculosis of warm-blooded animals.

Ec25-228 Farm Slaughter Of Hogs, Wm. J. Loeffel

University of Nebraska-Lincoln Extension: Historical Materials

Slaughtering hogs and curing the meat on the farm is a common practice which makes available a palatable and nutritious food. It utilizes labor at a season of the year when usually there is no great rush of work.

As a general rule, farm slaughter is not to be recommended until cold weather is a certainty, for warm weather is apt to cause heavy spoilage. Meat is a highly perishable food product, therefore absolute cleanliness should prevail in its handling. Contamination of meat by soiled hands, clothing, tools, or containers is not only insanitary but actually lowers the keeping quality …
