The Alkali Tolerance Of Tall Wheatgrass, David L. Carter May 1957

The Alkali Tolerance Of Tall Wheatgrass, David L. Carter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alkali land occurs adjacent to nearly every extensively irrigated area. Much of this land is too alkaline to produce profitable crops. Each year thousands of acres or land are going out of production because or increasing alkalinity. This presents one or the most acute problem which confronts irrigation agriculture today.

The Response Of Barley To Soil Moisture Tension And Fertilization, Mahmood Agah May 1955

The Response Of Barley To Soil Moisture Tension And Fertilization, Mahmood Agah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley is one of the important crops in many of the irrigated regions of the world. It is an important crop in Iran for both human consumption and livestock feed. In the United States and Europe it is used for livestock feed and beverages.

The income from this crop is moderate in comparison to that from other major agricultural products.

Barley production has a definite place in the economy of the region, because it requires only a small amount of care. It can be readily grown on poor lands. One of the factors contributing to the increased acreage of barley …

Bulletin No. 373 - Biennial Report Of The Utah Agricultural Experiment Station, 1952-1954 Dec 1954

Bulletin No. 373 - Biennial Report Of The Utah Agricultural Experiment Station, 1952-1954

UAES Bulletins

Our way of life is based on the ability of our agriculture to produce abundantly, efficiently, and at a low cost; and the position of agriculture today is largely a result of the research efforts of the state agricultural experiment stations and the United States Department of Agriculture. In the 66 years since the establishment of the Utah Agricultural Experiment Station, its scientists have found solutions to many of the problems peculiar to its location, topography, and climate. It is logical to rely on these same research forces to solve the problems of the future.

During the past biennium a …

Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss Jun 1949

Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During the summer of 1943 reports were received of rotted tubers occurring in fields of early potatoes in central Nebraska. An estimated 10 per cent of the tubers were found rotted in some fields on August 5. In November and December of the same year the late-producing area of western Nebraska reported the occurrence, at harvest and in storage, of tuber rots differing from those previously recorded for that area. Specimens appeared similar to those observed during the summer in central Nebraska. Isolations were made and pathogenicity tests were conducted both on tubers and growing plants to study the influence …


Charcoal Rot Of Corn And Sorghum, J. E. Livingston Apr 1945

Charcoal Rot Of Corn And Sorghum, J. E. Livingston

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In Nebraska, the charcoal rot caused considerable damage to the 1940 grain sorghum crop in the south central counties, and the following year it caused serious lodging and reduction of yield in both corn and sorghum in all sections of the state. Field observations indicated that some varieties of sorghum were damaged less than others; thus it appeared desirable to test thoroughly all varieties to determine whether any were sufficiently resistant to be recommended for field planting or to be used in a breeding program. It seemed desirable to study the influence of soil environment on infection and the development …

The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding Jun 1941

The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In this investigation a survey of Nebraska soils has been made in order to determine the distribution of the aerobic nonsymbiotic and symbiotic nitrogen fixers of the genera Azotobacter and Rhizobium respectively. In connection with this survey, some of the characteristics of the soils which may bring about this distribution were studied. Up to this time practically no research has been reported on the microflora of the soils of Nebraska. Hence there is little basis for predicting the activity of these organisms under environmental conditions as they exist here. It is hoped that this work will not only supply some …

Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev Aug 1937

Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present work was undertaken with the purpose of investigating the physiology of different strains of A. scabies as compared with saprophytic Actinomyces. By a comparative study of these groups, it was thought that differences in the physiology of the two might be found which would give a better understanding of the nature of this parasitism and also of the metabolism of Actinomyces in general. In addition, it was hoped that the determination of the factors influencing the parasitism of Actinomyces might establish a basis for the development of more efficient methods of controlling scab diseases. The present investigation …


The Tympanis Canker Of Red Pine, John Raymond Hansbrough Jan 1936

The Tympanis Canker Of Red Pine, John Raymond Hansbrough

Yale School of the Environment Bulletin Series

A new disease of red pine has recently been found in southern Connecticut, Rhode Island, eastern Massachusetts, western and central New York, northern New Jersey, eastern Pennsylvania, central Ohio, and southern Michigan. It is of serious consequence only on plantation-grown red pine, but it also occurs occasionally on eastern white pine. On the former host it is characterized by axially elongated, annual main-stem cankers which are always centered at the nodes. Infection takes place through adhering lateral dead branches and the growth of the fungus after it gains entrance to the stem.is usually very rapid-Le., cankers up to three feet …


A Study Of Some Species Of Pediastrum And Scenedesmus, Irene Cull Jun 1932

A Study Of Some Species Of Pediastrum And Scenedesmus, Irene Cull

Bachelors’ Theses

Although regarded by the untrained observer as slime, filth and scum, algae are fascinating to the botanist who has become interested in them. Algae are found everywhere; they are our commonest water plants. Among the green algae we have some of the most beautiful and fascinating forms in the plant kingdom and undoubtedly Pediastrum and Scenedesmus, the two genera studied, are among the most beautiful of all.

Alfalfa Investigations, T. A. Kiesselbach, Arthur Anderson Dec 1926

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.

Chapter Three: Establishment Of The Agricultural College, Robert Crawford Jan 1925

Chapter Three: Establishment Of The Agricultural College, Robert Crawford

These Fifty Years: A History of the College of Agriculture of the University of Nebraska

ESTABLISHMENT OF THE AGRICULTURAL COLLEGE

IT IS here that we draw the dividing line and proceed with the history of the Agricultural College rather than that of the University. Having seen the University established with its integral college units, it is now fitting to devote our attention primarily to the College of Agriculture, with only such references to the University as occasion demands.

It will be recalled that one of the primary purposes of the Land Grant Act of -1862 was to offer industrial education to the people, or as the Act stated, "to teach such branches of learning as …


Potato Wilt And Stem-End Rot Caused By Fusarium Eumartii, R. W. Goss Jun 1924

Potato Wilt And Stem-End Rot Caused By Fusarium Eumartii, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to obtain more information regarding the pathogenicity of Fusarium eumartii and to compare its action with F. oxysporum, in order to distinguish between and to determine the relative importance of the diseases produced by these two organisms. An effort was also made to explain the many negative results of isolation studies reported by various investigators, as well as the inconsistent results often reported in studies of the transmission of wilt by infected tubers. Investigations dealing with the effect of certain environmental conditions on the occurrence of the disease were also undertaken. All of the …


Improvement Of Small Grains By Pure Line Selection, Dilworth Walker May 1923

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.


Mendelian Inheritance In Wheat Hybrids, J. Leo Mortensen May 1923

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 …


Relation Of Environment And Other Factors To Potato Wilt Caused By Fusarium Oxysporum, R. W. Goss Mar 1923

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.
