Circular No. 6 - Measurement And Distribution Of Irrigation Water, L. M. Winsor

UAES Circulars

This circular has been prepared to meet the more urgent and immediate needs of the water user. The complications which usually arise in water measurement have been eliminated to such an extent that anyone who will follow the few simple instructions outlined in the following pages can learn to measure the flow of irrigation streams under ordinary conditions.

A Comparative Study Of The Structure And Origin Of The Yolk Nucleus, John P. Munson

Biology Faculty Scholarship

The question as to the comparative structure and origin of the yolk nucleus involves several other problems:

1. Is the yolk nucleus a normal element of the egg cytoplasm, or is it associated with pathological states of the egg, or is it an artefact due to reagents?

2. Is there a necessary connection between one form and another such that one can be derived from the other?

3. Is it an amorphous chemical substance or does it possess anything suggesting permanence of structure?

4. Does it arise de novo or is it a modification of something similar existing in the …

Spraying As An Essential Part Of Profitable Apple Orcharding, R. A. Emerson, R. F. Howard, V. V. Westgate

University of Nebraska Historical Extension: Bulletin

It was therefore planned from the start not merely to demonstrate the possibility of controlling apple insects and diseases but also to determine whether they could be controlled profitably. To accomplish this it was necessary to know: exactly what it cost to spray, what sprayed fruit yielded, and what it was worth in comparison with unsprayed fruit from the same orchards. In every spraying demonstration the time spent in mixing and applying the materials and the quantity of material used were recorded. The cost of labor of men and teams per hour was taken at the orchard owners' estimates and …

Present Methods Of Teaching Entomology At The University Of Nebraska, Lawrence Bruner

Department of Entomology: Faculty Publications

'When our Secretary sent out his preliminary notification of this meeting and asked me to take part in a discussion of "present methods of teaching Entomology," the matter at first seemed of little importance so far, at least, as the speaker was concerned. However, after giving the subject some thought I have decided that it might be well at least to take the time and trouble to attempt to explain briefly a few of the methods by which the student in Nebraska is enabled to absorb some entomological information. In order to do this with an unbiased feeling it might …

Discussion And Correspondence Coupling Vs. Random Segregation, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

To the editor of science: The suggestion offered by Morgan, in SCIENCE of September 22, to account for the coupling and repulsion of factors for various characters in inheritance in such forms as Abraxas, Drosophila, fowls, sweet peas, etc., incites this note.

Briefly Morgan's hypothesis is (1) that the materials representing factors that couple are "near together in a linear series" in the chromosomes; (2) that, when pairs of parental chromosomes conjugate, "like regions stand opposed "; (3) that "homologous chromosomes twist around each other," but that the separation of chromosomes is in a single "plane"; (4) that, thereby the …

New Elementary Agriculture, Charles E. Bessey, Lawrence Bruner, Goodwin D. Swezey

School of Biological Sciences: Faculty Publications

This is an agricultural nation. The products of the soil are the basis of her industries and her prosperity. The children of our great Commonwealths should be familiar with our crops, our grains and grasses, our flowers and fruits, our trees and shrubs and weeds, our domestic animals and birds and insects. Our children should have a practical knowledge of the management of a farm, of the composition of the soil, and of the adaptability of the farm and its soil for the cultivation of certain plants and the counter effect of such plant growth upon the soil. They should …

UAES Bulletins

The effect of cultivation and the growth of crops upon the nitrogen and humus content of soils has been studied by various investigators, both in America and Europe. In general, the results of the various investigations indicate that cropping and cultivation are very destructive of the organic. matter and the nitrogen of the surface soil.

Bulletin No. 107 - Improvement Of Utah Horses, John T. Caine Iii, H. J. Frederick

UAES Bulletins

Horse breeding in Utah, with some exceptions, has been carried on in a hap-hazard manner, and unsound horses of doubtful breeding have been purchased at high prices and have proven of little value. Where good blood has been introduced the temporary improvement has been marked, but as this work has not been followed up with care, results have not been lasting.

In spite of bad breeding, however, the standard of Utah horses has been advancing so that in western markets they command high pries. The climate, soil, feed and general conditions throughout the state make it an ideal place for …

Bulletin No. 105 - Factors Influencing Evaporation And Transpiration, John A. Widtsoe

UAES Bulletins

The irrigation investigations conducted by the Utah Experiment Station, some of the results of which form this *report, were undertaken for the purpose of adding to our knowledge of the natural laws upon which the art of irrigation may be safely built. The work has had for its dirrect object the study of the mutual relations of plants, soils and water, as these relations may indicate the most economic use of water for plant production. In pursuit of the investigations it became necessary not only to follow the movement of water in soils under irrigation conditions, but to determine also …

Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe

UAES Bulletins

It has been found that the production of one pound of dry plant substance on soils of average fertility, requires in humid districts not more than five hundred pounds of water, and in arid districts like Utah about seven hundred and fifty pounds. This indicates that the average rainfall of Utah, which is about twelve inches, if properly conserved in the soil, is sufficient to produce annually, without irrigation, from thirty to forty-five bushels of wheat to the acre, or corresponding yields of other crops. The realization of this truth has changed greatly our views of irrigation practices. The beginning …
