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

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.

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

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

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

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 …

Bulletin No. 142 - Irrigation Of Peaches, L. D. Batchelor

UAES Bulletins

The writer took up the study of the irrigation of peaches in the spring of 1913 after being connected in a co-operative way with a similar problem during the years 1911 and 1912. The results which follow are primarily from notes taken during 1913 and 1914. Free access has been made, however, to notes taken on the similar problem noted above, when the author was associated with Prof. Walter McLaughlin in connection with a co-operative irrigation problem. Some of the results of 1913 were materially influenced by the treatment of the orchard in 1912.

Circular No. 21 - Dry-Farming In Utah, F. S. Harris, A. D. Ellison

UAES Circulars

It was only a few years after the settlement of Utah in 1847 that occasional attempts were made to raise crops without the use of irrigation water, but these first attempts usually resulted in failure. Not until in the sixties could any degree of success be claimed. About this time, farmers in the valley of the Great Salt Lake and in Cache Valley began raising crops regularly on land located above the canal. From then to the present time a measure of success has been enjoyed by the better dry-farmer in some sections, and hardly a year of complete failure …

The Effect Of Climate And Soil Upon Agriculture, Russell R. Spafford

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

Field studies in farm management are at present almost whclly confined to measu ring the profitableness of a farm business and analyzing the effect of those factors which fall largely within the control of the farm operator. While factors beyond individual control have always been recognized in field work, very little attempt has thus far 'been made to measure their influence upon farming; It is true that with present weather, soil, botanical, census, and farm management data only preliminary measurements can be made, but nevertheless such measurements do much toward correlating what at present are disconnected facts in agricultural science. …

On A New Subspecies Of Porcupine From Nebraska, Myron H. Swenk

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

Publication NO.2 of the Nebraska State Biological Survey.

Nebraska porcupines all belong to the yellow-haired species (Erethizon epixanthum) , and these animals have never been abundant in the state. Formerly, however, they were much more numerous than today, and enjoyed a more extended range in the state than they do at the present time. Up to about 1885 these animals occurred across the northern portion of Nebraska east at least to Pierce and Madison counties, there being records of four specimens secured along the small streams tributary to the Elkhorn river in these two counties between 1870 and 1885. Also, …

Bulletin No. 141 - Variation In Minimum Temperatures Due To The Topography Of A Mountain Valley In Its Relation To Fruit Growing, L. D. Batchelor, F. L. West

UAES Bulletins

The most destructive weather enemy in all fruit growing sections is the late spring frost which frequently occurs after warm weather has caused the fruit blossoms to become fully developed. The variation in severity of such frosts in mountain valleys is a phenomenon well known to the practical orchardist. The actual extent of this variation and the contributing causes have claimed only a very little attention from scientific workers in the mountainous regions. The present publcation is a preliminary report of investigations which were planned to measure the extent of such temperature variations, and acertain if possible some of the …

Bulletin No. 140 - The Summer Pruning Of A Young Bearing Apple Orchard, L. D. Batchelor, W. E. Goodspeed

UAES Bulletins

The majority of horticultural writers seem to favor the summer pruning of apple trees. The practice, and the arguments made in its favor vary widely and in some instances seem almost contradictory. On the other hand some experimenters and practical workers have obtained negative results by summer pruning from the view-point of crop production and tree growth. Dickens(1) caused unproductive ten year old apple trees in Kansas to bear satisfactorily during the fourth year of summer pruning. The Gardners' Chronicle(2) compiled the opinions of more than one hundrend eighty-five fruit growers who practiced summer pruning, and about 82% of these …

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 …

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 …
