Circular No. 48 - Rural Credits In Utah, E. B. Brossard

UAES Circulars

The subject of rural credits is of interest to farmers, bankers, investors, and all others concerned about public welfare. This circular is written for the purpose of giving general information about agricultural credit conditions existing at the present time, with special reference to mortgage credit in Utah and the Federal Farm Loan System as now amended. The passage of the Federal Intermediate Credits Act, approved March 4, 1923 makes this an opportune time to check up on the situation.

Bulletin No. 186 - Irrigation Experiments With Sugar Beets, F. S. Harris, D. W. Pittman

UAES Bulletins

A previous bulletin of this station gives the results of an experiment on the irrigation of sugar-beets continuing for five years. Since this experiment was deemed of sufficient importance to merit our best attention and since the climatic conditions which largely determine what is the best irrigation practice may not for so short a period properly represent the average of the community, it was thought advisable to continue the experiment, with certain modifications, for an additional five years. This bulletin reports the results of these last 5-years' work together with such general conclusions as can be drawn from the entire …

Bulletin No. 187 - Irrigation Experiments With Potatoes, F. S. Harris, D. W. Pittman

UAES Bulletins

In a previous bulletin of this station are given the results of an experiment on different irrigation treatments of potatoes continued for five years. In view of the importance of the potato crop and of the importance of having it properly irrigated it was considered advisable to continue the experiment, with certain modifications based on experience, for a further period of five years. This total period of ten years should include most of the climatic variations which are common in this locality, and by eliminating the more unsatisfactory irrigation systems a closer approximation to the best system should be found. …

The Abortion Problem In Farm Live Stock, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

This casting out of a dead or at least abnormal fetus we call abortion. It constitutes the culminating accident in a process set into motion by disease or injury. To the breeder it is its most conspicuous feature, and it's more or less constant occurrence among live stock warrants us to speak of the abortion problem. It is the purpose of this publication to lay before our Nebraska breeders such information on the subject as can be gathered from the more recent literature and from observations in the field and the laboratory.

A Founder Of American Parasitology, Joseph Leidy, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

A biographical overview of American parasitologist Joseph Leidy and his work. bron September 9, 1823, Philadelphia, Pennsylvania, USA - died 1891.

Conclusion

A detailed study of his writing justifies the statement that no one has yet adequately presented or fully elucidated Leidy's contributions to helminthology and his writing will furnish rich lead to many future workers in this field. How monumental the task of preparing a record of the full life work of this extraordinary man who in the same breath as it were, in a single letter records discoveries of far reaching import on bacteria, amoebae, worms, and fossil …

Propagation And Renewal Of Strawberries, A. L. Ford

SDSU Extension Circulars

During the month of August there usually is a dull period for the strawberry club member. At this time there is nothing new coming up and because of this we feel that this month would be an excellent time to go into the propagation of strawberries and the renewal of strawberry beds. Every club member who intends to grow a few strawberries every year surely will find good use for this information.

Rammed Earth Walls For Buildings, U.S. Department Of Agriculture

Rammed Earth Collection (1923 - 1959)

Earth has been used for building dwellings from time immemorial. One method of use, superior to others, and which was known to the Romans has been preserved by tradition .t o modern times. This method consists of ramming slightly moist, specially selected earth, without the addition of straw or other material, between movable forms, and is known by itsFrench name, " pise de terre," which means "rammed earth." Pise de terre is a reliable building material when properly handled and is admirably adapted to structures on farms distant from transport routes. Little information has been published on rammed earth in …

Bulletin No. 185 - The Influence Of Nitrogen In Soil On Azofication, J. E. Greaves, D. H. Nelson

UAES Bulletins

Many soils of the arid west have a rich active azofying flora. This is due in no small measure to their composition. They are high in calcium and magnesium carbonate and contain a good supply of available phosphorus and potassium but have a low nitrogen content. They are poor in organic carbon; hence, their native supply of energy is limited. It is well-known that a liberal supply of rapidly decaying organic matter is beneficial, and this is being supplied to some soils in the form of manures. This will increase the nitrogen content of the soil. What effect will this …

The Plains False Wireworm And Its Control, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Circulars

The last three crops of winter wheat, and especially the crop of 1922-23, have been seriously injured in southwestern Nebraska and especially on the dry land farms of Cheyenne, Kimball, Banner, Morrill, Garden, Deuel , Keith, Perkins, and Hitchcock Counties, by an abundance of hard-bodied, cylindrical, shining waxy yellow, soil-infesting larvae. These greatly resemble wireworms and are often mistaken for them, but they differ conspicuously in being more active and having well-developed, club-shaped antennae, long and stout front legs, and a less flattened body with a distinctly upturned tip. These larvae destroy the planted seed in the fall and eat …

Picking, Marketing And Canning Of Strawberries, A. L. Ford

SDSU Extension Circulars

Some may believe that strawberry picking is not a subject to be taken up for July but let us tell you why we are taking it up at this time. Club members who are planting spring bearing varieties will not get a crop until next June, but those who have planted everbearing varieties should get a fair crop this fall if it is not too dry. We are giving the first year members this information now so that they can use it for their everbearing varieties. This information should be filed away carefully so you can turn to it again …

A Study Of The Tissues Of Leaves Of Certain Angiosperms, Amybelle Halbert Brady

Bachelors’ Theses

The leaves used for the study of the tissues were those of the Oleander, Ficus, Ivy, Cyperus and the Aristolochia. Portions of the leaves used were cut into rectangular pieces, about one centimeter long and one half centimeter wide, each piece including a portion of a large vein and its subsidiary veinlets. The material was placed into chrome acetic acid solution. After twenty four hours it was a shed in running water for twelve hours and then dehydrated by means of alcohol, and was then imbedded in paraffin. The sections used for the study were cut from 12 to 15 …

Farm Sanitation, G. S. Weaver

SDSU Extension Circulars

Sanitation means to keep things clean, to be hygienic. Farm sanitation helps to preserve the health of domestic animals and, indirectly, the health of the people that live on the farm. Cleanliness, sunlight, fresh air, and disinfectants are the important factors in sanitation.

Vestigial Pleometrosis In The North American Polistes Pallipes Lepeletier, Joseph Bequaert

Ba

In the October-December, 1919, issue of this BULLETIN my esteemed friend, Mr. Wm. T. Davis, has published some observations of the common American social wasps, a most welcome addition to the scanty literature of the subject in America. Among other interesting points, he relates several cases in which two, three, or four queens of the common Eastern Polistes pallipes Lepeletier ( = metrica Say; variatus Say) had worked together in establishing a new colony, though in this as in other species of Polistes each queen as a rule starts her nest alone.

Bulletin No. 184 - A Farm-Management Study Of The Great Salt Lake Valley, George Stewart

UAES Bulletins

This survey had for its purpose the study of farm organization in Great Salt Lake Valley. It is hoped that some conclusions may have been reached as to how to improve farming conditions. The records were taken during the summer of 1915 and consequently represent the farm business for 1914. Ordinarily the period of time that has elapsed since the records were taken would be too long to justify their being published. In view of the fact, however, that the World War began in 1914 and that its effects on the prices of farm products lasted until 1921, it is …

Improvement Of Small Grains By Pure Line Selection, Dilworth Walker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present economic status of grain farming in the United States calls for adjustments in various ways. Legislation, such as price fixing, can do very little. Adjustment of acreage along with improved methods of marketing can do much. But improvement of the grains grown through breeding processes to increase the yields per acre and improve the milling quality, will render a service of permanent value, since all of the results appear in the profit column.

Hybridization Of Wheat, Floyd M. Beach

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to set forth the purpose of wheat hybridization. To do this properly it is necessary to know the history of hybridization of plants. Also to know some of the workers in this field and the hybrids produced by them. In the work at the Experiment Stations the various experimenters have discovered many interesting facts which it is necessary to know and understand. To thoroughly comprehend the work it is also necessary to do the actual processes of the work and to carry the hybrid through several generations and eventually to the goal for which …

Mendelian Inheritance In Wheat Hybrids, J. Leo Mortensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Until the beginning of the present centry the general opinion was that Egypt and Mesopotamia were the earliest homes of cultivated plants. Recent translations of the old Chinese records, however, reveal the fact that many of our cultivated plants were grown by the ancient peoples of China prior to the time of the Egyptians.

Dettweiler (11) (1914) writes: "Today it is admitted--except by a few--that the original home of the primitive European population, the Indo-Germans, is not Asia but northern Europe, that they developed their culture there in the late stone age, and that they then dispersed in their wanderings …

Effect Of Root-Rot Upon Sugar-Beet Seed Production, Louis F. Nuffer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to considerable loss through root-rot of mother beets while in storage during the winter of 1918-1919 the Amalgamated Sugar Company asked advice in regard to planting beets which had decay lesions on them. Would the beets yield seed if planted? How much seed would these beets yield as compared with healthy beets? Would the seed produced be injured by having been grown on decayed beets? It was felt that an experiment carried out with the above questions in view would bring out many facts upon which to base conclusions in answering the questions of the Sugar Company.

A Study Of The Flowering And Fruiting Habits Of The Delicious Apple, Emery R. Ranker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the most disagreeable and at the same time the most unprofitable features of commercial apple production is the tendency of most apple varieties to "take a rest" every other year in order to regain the strength given to the production of a very heavy crop the previous year, and thus be able to repeat the process of heavy production the following year. This process is referred to as "off-year" or alternate bearing. Various causal relationships have been suggested , from time to time, by the different workers in the field but the suggestion now most generally accepted, and …

The Common Intestinal Roundworm Of Swine, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Circulars

The large intestinal roundworm of pigs is a very common parasite, and is probably present in every hog raising district of Nebraska. Up until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.

Relation Of Environment And Other Factors To Potato Wilt Caused By Fusarium Oxysporum, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present work was undertaken to determine the influence of some environmental factors on the infection and progress of the disease potato wilt. The work has not progressed to the point of determining the exact relation of each of these factors. However, the results thus far obtained are presented here in order to direct attention to the nature and distribution of the disease in relation to the environmental conditions under which certain types of infection take place.
