Transpiration As A Factor In Crop Production, T. A. Kiesselbach Jun 1916

Transpiration As A Factor In Crop Production, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of experiments reported in this bulletin has been to determine principles according to which water is used by crops. In many agricultural districts, water is frequently a seriously limiting factor in crop production. It has been thought that some means might be devised through a correct understanding of the principles involved, whereby economy in the use of water in farm practice could be increased. In this effort there are two chief points of attack, namely, (1) adjusting the external factors to the needs of the plant, and (2) selecting plants adapted to the conditions.


The Colloidal Swelling Of Wheat Gluten In Relation To Milling And Baking, F. W. Upson, J. W. Calvin Jun 1916

The Colloidal Swelling Of Wheat Gluten In Relation To Milling And Baking, F. W. Upson, J. W. Calvin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Our experiments deal with the changes in hydration capacity of gluten under different conditions and were carried out by determining accurately the amount of water absorbed by gluten from solutions of varying concentrations of different acids, both with and without the presence of salts.

Bulletin No. 143 - Fruit Tree Root Systems: Spread And Depth, A. B. Ballantyne Apr 1916

Bulletin No. 143 - Fruit Tree Root Systems: Spread And Depth, A. B. Ballantyne

UAES Bulletins

As mentioned in Utah Station Bulletin No. 124, seepage conditions on the Southern Utah Experiment Farm were responsible for the removal of about 5 acres of vineyard in 1908, and 7 acres of mixed peach orchard in 1910, all of which were on the lower or western half of the farm.

These orchards and vineyards had always received good care, clean culture being practiced in fact as well as name. The results for a number of years were all that could be desired, when the trees and vines began to die questions arose as to the cause: since in spite …


Circular No. 20 - Capsule Method Of Breeding Mares, W. E. Carroll, J. Frederick Apr 1916

Circular No. 20 - Capsule Method Of Breeding Mares, W. E. Carroll, J. Frederick

UAES Circulars

Some inquiry has been received by the State Board of Horse Commissioners relative to the capsule method of breeding mare. With the thought that a brief statement of the instruments used and the methods employed in the so-called capsule method of breeding might be useful to stallion men in general, this little circular has been prepared.


Ecological Investigations Upon The Germination And Early Growth Of Forest Trees, Richard H. Boerker Apr 1916

Ecological Investigations Upon The Germination And Early Growth Of Forest Trees, Richard H. Boerker

University Studies (University of Nebraska) (1888–1984)

Briefly stated the purpose of the present investigation is to inquire into the effect of the more important habitat and seed factors upon the germination and early development of certain American forest trees in control cultures in the greenhouse for the purpose of obtaining data that may be used in the ~ilvicultural management of these species.

Note On An Interesting Case Of Two Generations Of A Parasite Reared From The Same Individual Host, Philip H. Timberlake Mar 1916

Note On An Interesting Case Of Two Generations Of A Parasite Reared From The Same Individual Host, Philip H. Timberlake

Th

In the course of investigations of Dinocampus americanus (Riley), a common Braconid parasite of many of the larger species of Coccinellids, conducted in relation to cereal and forage crop insects, several interesting features have developed, not the least important of which is the discovery that parasitism is not invariably fatal to the beetles.

Circular No. 19 - Licensed Stallions In Utah During The Season Of 1915, W. E. Carroll

UAES Circulars

In presenting this report of the State Board of Horse Commissioners, it is thought best to include very little which does not bear directly upon the number and distribution of licensed stallions and jacks. Other material treating different phases of the horse industry appears in other circulars from the Board.

A Genetic Study Of Plant Height In Phaseolus Vulgaris, R. A. Emerson Mar 1916

A Genetic Study Of Plant Height In Phaseolus Vulgaris, R. A. Emerson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

When pole and bush beans are crossed, 3:1 segregation results whether the pole bean is very tall or only medium in height and whether the bush bean is very short or relatively tall. To determine the interrelation of these two types of behavior by an analysis of the factors concerned in height of plants in beans and by a study of their mode of inheritance was the object of the investigations reported here.


Gongylonema In The Role Of A Human Parasite, Henry Baldwin Ward Mar 1916

Gongylonema In The Role Of A Human Parasite, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

A specimen of Gongylonema, probably G. pulchrum, has been recovered from man. This species is normally a parasite of the pig.

Infection of the human host was brought about probably by the ingestion of larvae in the infective stage which had developed in some insect. Very likely the croton bug, known by experiment to be able to serve as intermediate host for this species, was the source of the infection which might readily occur by accident.

The presence of the parasite was accompanied by clinical symptoms indicating marked digestive and nervous disturbances, associated with anemia. These symptoms …

Circular No. 18 - Better Horses For Utah, W. E. Carroll Feb 1916

Circular No. 18 - Better Horses For Utah, W. E. Carroll

UAES Circulars

The two chief factors which determine the profits realized from the horse breeding business are the cost of production and the quality of the product put on the market. As land values increase, taxes automatically become higher, and this together with the increasing cost of labor, makes the feed and care given the horse more expensive. These factors are so completely independent of the horse breeder that he has little control over the cost of production. This statement is not intended to convey the idea that no account should be taken of costs, or that costs do not vary. Quite …
