Bulletin No. 159 - Soil Moisture Studies Under Irrigation, F. S. Harris, A. F. Brakcen

UAES Bulletins

Under normal precipitation the variety of crops which can be successfully grown in the West is limited. Of necessity, irrigation was practised and with it came many complex problems. The water requirements of different crops, the water-holding capacity of soils, the movement of soil moisture, and numerous other related problems have given themselves up for investigational work.

Measuring Silage And Capacity Of Silos, L. W. Chase

Nebraska Agricultural Experiment Station: Historical Circulars

The condition of the corn at filling time, the rate of filling, and the length of time settling has taken place before measuring the depth of the silage, all tend to cause variations in the weight per cubic foot of the silage and in the tonnage that can be placed in a silo. The greatest variation comes when very green corn or very ripe corn is used, and because of this it is possible that a cubic foot of green silage, which may weigh fifty pounds, holds no more dry matter than a cubic foot of overripe silage which weighs …

Bulletin No. 153 - Selecting Dairy Bulls By Performance, W. E. Carroll

UAES Bulletins

Success in any system of breeding requires that each generation approach more nearly the object in view than has all preceding generations. Such progress is possible only when proper judgment is exercised and the best methods employed. In cattle breeding, for economic reasons, the bull is usually expected to contribute more to this general improvement than is the cow. To make this possible, the bull must therefore have been subjected to more rigid selection than the cow in order to eliminate more of his undesirable characters. If he contains few undesirable characters, from the breeding standpoint, he must of necessity …

Spraying Experiments In Nebraska, J. Ralph Cooper

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The more important questions which were considered during the three years covered by the present report were as follows: 1. How many summer sprays are required and when should they be applied? 2. What is the difference in efficiency between various brands of arsenate of lead? 3. What are the relative values of lime sulphur and Bordeaux as fungicides for spraying apples? 4. Is it possible to lessen or prevent Bordeaux injury and at the same time control fungous diseases? 5. Is it possible to interchange Bordeaux and lime sulphur in a spray schedule in such a manner as to …

New Hymenoptera, J. C. Crawford

Co

Professor Cockerell has recently (Psyche, XXIII, 176- 178, 1916) published on the synonymy of this group, and at present it seems best to treat Zacesta and Panurgomyia as synomyms of this genus. Z. rufipes is very similar to the genotype of Hesperapis and is probably the male of a very closely allied species. Panurgomyia fuchsi belongs to the group of H. eumorpha and (Panur-gus) H. regularis Cress. and is very close to regularis. The type of fuchsi is in bad condition and the identification is, therefore, somewhat' uncertain.

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.

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 …

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. …

Evaporation And Plant Zones In The Cedar Point Marsh, Paul B. Sears

Papers in Ecology

Yapp in trying to account for the xerophytic structure of marsh plants by means of evaporation studies has shown a definite correlation to exist between the strata of marsh vegetation and rates of evaporation at corresponding levels. The following studies were made in an attempt to discover what additional correlations, if any, exist between distribution of marsh plants and the evaporational power of the air at different portions of the habitat. While the exact quantitative significance of such work as the following may be brought into question, as it often is, the striking results obtained by Transeau, Livingston, Fuller, Weaver, …

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 …

Notes On The Trematode Genus Telorchis With Descriptions Of A New Species, Horace Wesley Stunkard

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

The study of abundant material, both adult and immature forms from the trematode genus Telorchis, including four species new to science and others from new hosts and localities, has given data for the first general discussion of the genus yet made. The sub-genera Telorchis and Cercorchis proposed by Lühe intergrade and can not be retained. T. augustus and T. leptus if correctly described should be removed to an independent genus. The new and some older species are discussed in detail.

A Brief Sketch Of The Life And Work Of Charles Edwin Bessey, Raymond J. Pool

Papers in Systematics and Biological Diversity

Charles Edwin Bessey, professor of botany and head of the department of botany in the University of Nebraska since 1884 and a conspicuous figure in American science and education, passed away at his home in Lincoln on February 25, 1915, after a critical illness of four weeks.

The Bessey family is of French extraction, the original form of the name being Besse. The tradition is that the early members of the family, who were Huguenots, were compelled on account of religious persecution to flee to England from the old home near Strassburg in Alsace. This exodus occurred in the latter …

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 …

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 …
