Circular No. 91 - Establishing Snow Courses And Making Snow Surveys, George D. Clyde Dec 1930

Circular No. 91 - Establishing Snow Courses And Making Snow Surveys, George D. Clyde

UAES Circulars

The major portion of the annual precipitation in the semi-arid west falls as snow. It piles up in the mountains and forms the main source of the water in the creeks and rivers draining the mountainous areas. Some of these streams flow the year around while others and intermittent, flowing only as long as the snow in the mountains lasts. The water-supply for irrigation, power development, and municipal purposes is derived largely from winter snows. A knowledge of the extent of the snow cover and its water content is, therefore, necessary for the proper utilization of this great natural resource. …


Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick Dec 1930

Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick

UAES Bulletins

For a number of years many tons of sprayed or dusted hay have been fed successfully to livestock by stockmen interested in controlling the alfalfa weevil; nevertheless. the supposed cases of poisoning that have been reported naturally have caused concern among feeders.

Further confusion on this question has resulted from reports on studies designed to determine the effect of lead arsenate instead of calcium arsenate.

Whether the lead in lead arsenate has been a more injurious agent than the arsenic, of course, is difficult to state. Most of the experiments performed in the feeding of sprayed or dusted hay have …


Breeding Winter Wheat For Resistance To Stinking Smut (Tilletia Levis And Tilletia Tritici), T. A. Kiesselbach, Arthur Anderson Dec 1930

Breeding Winter Wheat For Resistance To Stinking Smut (Tilletia Levis And Tilletia Tritici), T. A. Kiesselbach, Arthur Anderson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Several productive lines of hard red winter wheat which are highly resistant to both species of stinking smut (Tilletia levis and T. tritici) have been isolated from the Turkey variety. Artificial-smut and stem-rust epidemics and controlled freezing have been found useful supplements to field-performance tests. Differential reactions of the new Turkey selections and a number of hybrid selections and established resistant varieties to collections of bunt from a number of states give definite evidence of the occurrence of mild and virulent physiologic forms of both species. Certain selections have proved very resistant to some of the smut collections and …

Bulletin No. 222 - A Quarter Century Of Dry-Farm Experiments At Nephi, Utah, A. F. Bracken, George Stewart Nov 1930

Bulletin No. 222 - A Quarter Century Of Dry-Farm Experiments At Nephi, Utah, A. F. Bracken, George Stewart

UAES Bulletins

Utah is naturally an arid state with precipitation varying from 3.71 inches at Wendover, located in the vast desert region on the western border, to more than 40 inches on some of the mountain ranges. Desert and mountain areas and other untillable land combined total about 95 per cent of Utah's land area. The remaining 5 per cent constitutes all the land which will yield to cultivation either by irrigation or by dry-farming.

Durinog the 76 years that dry-farming has been practiced in Utah, many change in tillage practices, cropping systems, crops, and crop varieties have taken place in keeping …


Circular No. 90 - Swine Production In Utah, Harry H. Smith Nov 1930

Circular No. 90 - Swine Production In Utah, Harry H. Smith

UAES Circulars

During the last 20 years there has been a marked change in the type of hogs from the short-legged, wide-bodied or "hot-blood" type to a longer, somewhat more narrow-bodied, "leggier" type. For development of size in hogs they must have (1) length and depth of body, (2) length of leg, and (3) large but not coarse bones. The long-bodied rather "leggy" pig grows rapidly and makes the larger hog. While the modern hog is still a lard hog, it is not as thick and broad as were its predecessors. It is logical to assume that the hog of the future …


The Food Habits Of The Ring-Necked Pheasant In Central Nebraska, M. H. Swenk Nov 1930

The Food Habits Of The Ring-Necked Pheasant In Central Nebraska, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Pheasants, including the Chinese and the so-called English pheasants, with their hybrid the ring-necked pheasant, have been introduced and established in a large area in the northern United States during the past 50 years. During the past 15 years continued importations of these birds into Nebraska, together with the rapid increase of those already established, have built up a large pheasant population in the state, estimated at more than a million birds. They have especially thrived in a block of 16 counties in east-central Nebraska. Protection was afforded them until 1927, when short open seasons were permitted in the fall …

Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack Aug 1930

Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack

UAES Bulletins

For 17 years the late Dr. Herbert J. Pack, former Station Entomologist, made a study of the reptiles and amphibians of Utah. His original idea was to publish a comprehensive treatment of the snakes and lizards of his state, and whenever opportunity was afforded collected data on their distribution, habits, and economic importance. At the time of his death, on January 5, 1930, many notes and drawings of lizards were left; a manuscript on snakes, presented for his master's thesis to the Utah State Agricultural College in 1923, was also in his possession. Bulletin 221 contains essentially the information presented …


The Incidence Of Avian Tuberculosis In Mammals Other Than Swine, L. Van Es, H. M. Martin Aug 1930

The Incidence Of Avian Tuberculosis In Mammals Other Than Swine, L. Van Es, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The recognition of a very widespread and intense distribution of avian tuberculosis on the farms of a wide area of the United States, as well as the involvement of a mammalian species also, brought to the foreground the question whether or not the great prevalence of poultry tuberculosis could be of importance also from a public health point of view. This phase of the problem not only pertains to the people on the farms but likewise is of fundamental importance to the consumers of poultry produce. European authors had already identified the avian tubercle bacillus in human lesions while in …


The Use Of A Small Electric Motor In Silo Filling, E. E. Brackett, E. B. Lewis Aug 1930

The Use Of A Small Electric Motor In Silo Filling, E. E. Brackett, E. B. Lewis

Nebraska Agricultural Experiment Station: Historical Circulars

Filling a silo 30 feet or more in height with a motor as small as five horsepower has been looked upon in general by Nebraska farmers as an impractical, if not impossible, procedure. The practice is not unheard of in other states, and certainly the possibility of avoiding the large tractor-driven cutters and the large crews will be welcomed by those who have available service from power lines.

A Record Of Post-Glacial Climate In Northern Ohio, Paul B. Sears Jul 1930

A Record Of Post-Glacial Climate In Northern Ohio, Paul B. Sears

Papers in Ecology

This paper reports the probable course of post-glacial forest succession in northern Ohio, as indicated by a study of fossil pollen deposited in the Bucyrus Bog. The object of the study has been to trace in greater detail than has yet been possible the course of climatic change since the end of the Wisconsin glaciation.

The principle employed is one which has been used in numerous European studies since 1915. It consists of a tabulation of the percentages of pollen grains of each species found in successive levels of bog deposits, and deduction of the prevailing forest composition at each …


Underground Plant Development In Its Relation To Grazing, J. E. Weaver Jul 1930

Underground Plant Development In Its Relation To Grazing, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Grasslands or grazing lands are relatively dry lands. Drought, at least in the surface soil, is always imminent. The necessity for the seedling to make immediate and extensive contact with deeper, moister soil is apparent. The water relation is usually controlling, and the success or failure of the seedling largely depends upon its ability to develop an absorbing system adequate in extent and activity to furnish the necessary supply.


Circular No. 86 - Coccidiosis Of Chicken, D. E. Madsen Jun 1930

Circular No. 86 - Coccidiosis Of Chicken, D. E. Madsen

UAES Circulars

Coccidiosis is a highly contagious disease of chickens and other fowls which is widespread and destructive, especially to half-grown chickens. The heaviest losses occur in chicks from 2 to 10 weeks of age. Just prior to and during their first laying season, pullets sometimes become affected with the disease in a chronic form. The cause is a microscopic protozoan parasite, the oocyst form of which is present in the droppings of diseased birds in large numbers. At least three species of the parasite have been recognized in fowls. The severity of the outbreak is thought to be determined by the …

Bulletin No. 219 - Twenty-Eight Years Of Irrigation Experiments Near Logan, Utah: 1902-29, Inclusive, D. W. Pittman, George Stewart

UAES Bulletins

Since 1902 irrigation experiments have been a major part of the research activity on the Greenville (Central) Experimental Farm near Logan, Utah. The experiments have been concerned mainly with the effects of different quantities of irrigation water, the minimum water requirement of crops, and the effects of different seasonal distribution of the water. This publication aims to give a brief summary of this work as it relates to crop yields as well as the more recent results up to and including 1929.

Bulletin No. 218 - The Alfalfa-Seed Chalcis-Fly In Utah: 1926-29, Inclusive, Charles J. Sorenson Jun 1930

Bulletin No. 218 - The Alfalfa-Seed Chalcis-Fly In Utah: 1926-29, Inclusive, Charles J. Sorenson

UAES Bulletins

During the past 10 or 15 years alfalfa-seed has constituted the major crop in western Millard County and in most of that portion of the Uintah Basin which is situated in Utah. In these sections of the state various natural conditions generally have been favorable for seed production. Within the last five years seed growers have thought that one of the principal limiting factors of the industry has been the alfalfa-seed chalcis-fly. Accordingly, a preliminary survey in the seed districts of the state was made in the fall of 1925 by the Utah Agricultural Experiment Station.

The greater part of …
