Management Of Irrigated Land: Report Of The Scottsbluff Experiment Substation, Mitchell, Nebraska, Fritz Knorr

University of Nebraska-Lincoln Extension: Historical Materials

SUMMARY.
Seepage may be prevented to some extent by employing proper methods of irrigation. Overirrigation may have a tendency to water-log the soil.
A small head of water, properly used, will irrigate more land and do better work than a large head gone over the land hurriedly.
The distance of irrigation ditches should be such that the water may travel between the ditches in about two hours.
If land can be irrigated in the fall with the same care that crops are irrigated in the summer, there is an advantage to fall irrigation. If water cannot be properly cared for …

A Study Of Senescence, William T. Sanger

Historical Dissertations & Theses

A complete study of senescence would involve, not only a consideration of man, but of lower organisms, animal and plant, as well as institutions, races, nations, even the cosmos itself; for assuredly the phenomena of decay are as universal and intricate as those of genesis. In the present study, however, it will be attempted merely to indicate, first, the best that has already been done upon human senescence; second, to add further findings; and third, to set more definitely a number of new problems for future investigation.

Corn Silage And Alfalfa Hay For Beef Production, Ralph K. Bliss, C. B. Lee

University of Nebraska-Lincoln Extension: Historical Materials

SUMMARY.

1. A ration of corn and alfalfa hay produced the cheapest gains of any ration used. Furthermore, the steers fed corn and alfalfa hay made as rapid gains as did the steers on any other ration.
2. Had the alfalfa hay used in the first experiment cost $20 per ton, the average profit on the three lots receiving alfalfa would have been 15 per cent greater than the profit on the best one of the three lots not receiving alfalfa.
3. Cold pressed cottonseed cake did not give as good results, as regards either rate of gain or economy …

He implies that these issues are damaging the reputation of the orange.

Raising The Dairy Calf, E. G. Woodward

University of Nebraska-Lincoln Extension: Historical Materials

There are in Nebraska more than 600,000 dairy cows. The average period of usefulness of the dairy caw is not more than eight years. This means that to maintain the dairy herds of Nebraska at their present size between 70,000 and 80,000 heifer calves must be raised each year. To mate these cows properly with dairy bred bulls will require the rearing of about 8,000 bulls yearly. Aside from the necessity of maintaining the herds at their present size, the importance of calf raising to the Nebraska dairyman lies in the fact that this is the surest and most satisfactory …

Soy Beans And Cowpeas, Theodore A. Kiesselbach

University of Nebraska-Lincoln Extension: Historical Materials

In recent years considerable interest has been manifest in Nebraska concerning soy beans and cowpeas; and numerous inquiries regarding them have come to the Experiment Station. The cowpea is regarded as a profitable crop chiefly in the cotton states, but has some importance as far north as Missouri, Illinois, Indiana, and Ohio. On the other hand, the soy bean is adapted primarily to the Northern States between the regions best suited for cowpeas in the South and Canada field peas in the North. The Central States in which they are most commonly grown are Illinois, Indiana, Ohio, and Michigan, and …

A Handbook Of Nebraska Grasses : With Illustrated Keys For Their Identification, Together With A General Account Of Their Structure And Economic Importance, E. Mead Wilcox, George K. K. Link, Venus W. Pool

University of Nebraska-Lincoln Extension: Historical Materials

The true grasses belong to the one family Poaceae, often called Gramineae, and constitute a very well defined natural group of plants. This family comprises upward of 3,000 species distributed among almost 300 genera. From the economic point of view the family is of supreme importance thru the fact that here belong the cereals, which supply a large part of the food of man, and the forage grasses which are so important as feed for our domesticated animals.

The genera and species are for the most part separated by artificial characters—a fact which renders their study and identification extremely difficult …

Otacariasis In The Bighorn, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

The ear of a mountain sheep at Estes Park, Colorado, USA, was found to be heavily infested with a Sarcoptid mite which was not the common scab mite of domesticated sheep but is new in this country.

This form is similar to a mite found in the ear of goats in the Pyrenees and in the Congo. Nevertheless there is reason to consider it a new species and it is named Psoroptes cervinae.

The complaint to which it gives rise is likely to be serious if its effects are like those of the related European form. The Bighorn …

The Habits, Life History, And Structure Of A Blood-Sucking Muscid Larva (Protocalliphora Azurea), Albert Francis Coutant

Harold W. Manter Laboratory of Parasitology: Library Materials

While studying the blood parasites Halteridium and Proteosoma, and the Filaria of the common crow (Corvus americana), my attention was attracted by an external parasite of some young nestlings which were brought into the laboratory. Observations on this parasite, which proved to be the larva of Protocalliphora azurea (Fall.), form the basis of this paper. The parasite is the immature form of one of the so-called "blue-bottle" or flesh-flies, whose larvae are generally regarded as useful scavengers. More careful observations on the life-histories of many species, however, have shown that they may be, and often are, parasites …

Bulletin No. 138 - How To Control The Grasshoppers, E. D. Ball

UAES Bulletins

There is no longer any reason why a farmer or a community of farmers should allow their crops and meadows to be destroyed by swarms of grasshoppers. Our knowledge of their habits has increased and better methods of destruction are known, so that at the present time the grasshopper takes its place in the list of crop pests that can be controlled by those who desire to do so. In the old days when countless numbers of the Rocky Mountain locusts (M. spretus) settled down on the crops of the few scattering settlers of the plains or Intermountain region, there …

Bulletin No. 137 - The Quality Of Home Grown Vs. Imported Wheat, Robert Stewart, C. T. Hirst

UAES Bulletins

In 1907 a number of new varieties of wheat were introduced into Utah and have since been grown on the Nephi Experimental Dry Farm, under strictly dry farm conditions. In view of the well-known influence of environment upon the quality of the wheat it is of importance to study the effect of climatic conditions in Utah upon this introduced seed. Wiley (1) says: "The quality and properties of wheat depend more upon the environment in which it is grown than upon the species to which it belongs. There is perhaps no other field crop in which environment, namely, conditions of …

Bulletin No. 136 - The Commercial Production Of Sugar Beet Seed In Utah, Frank S. Harris

UAES Bulletins

History of the beet sugar industry: The production of sugar from beets is a new industry when compared with the length of time that most kinds of crops have been used by man. It was only about 150 years ago that sugar was extracted from beets even in the laboratory, and at that time the percentage of sugar was so low that the expense of extracting was more than the sugar was worth. Just a little more than 100 years ago the first beet sugar factories were built, but it was nearly fifty years after this time before the industry …

The Bee Genus Holcopasites Ashmead, J. C. Crawford

Co

This genus was established by Dr. Ashmead in Trans. Amer. Ent. Soc., vol. 26, p. 82, 1899, but no species was included. The material on which he based his description is in the U. S. National Museum and bears his manuscript name H. pratti. This, however, is the species described by Robertson as Philerenius illinoiensis, which species I select as the genotype. To this genus also belong Phileremus pulchellus Cresson, P. heliopsis Robert., and Neopasites robertsoni Cwfd. as well as the new species described below.

Eine Biene, dercn Vorkomrnen in Deutschland bisher noch nicht festgestellt, und die wahrscheinlich mu verkannt wurde, ist Andrena angustior W. K. Sie ist nahe verwandt mit A. gwynana W. K., mit der sie, wie aucb ilue noch naheren Verwandten A. rufula Schmied. und A. symphyti Schmied., in der Grofse und in der Farbung des Haarkleides fast ganz ubereinstimmt. Von A. gwyana unterscheiden sich die 3 genannten Arten sofort durch das wenigstens teilweise hell behaarte Gesicht, welches bei A. gwynana schwarze Haare tragt.
