Bulletin No. 344 - The Nutritive Value Of Range Forage As Affected By Vegetation Type, Site, And State Of Maturity, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Native ranges of Utah are extremely heterogeneous. Pronounced variations exist in soil, seasonal rainfall, temperatures, and altitude on most grazing areas. Rough topography and micro-climates on even individual grazing allotments present variable vegetation types and site conditions. Such variations account for the comparatively large number of species and variable nutritive content found in range forage.


Progressive Development And Seasonal Variations Of The Corn Crop, T. A. Kiesselbach Dec 1950

Progressive Development And Seasonal Variations Of The Corn Crop, T. A. Kiesselbach

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The chief purpose of these studies has been to determine the normal growth changes that occur in the corn plant at successive intervals when growing in the field, and to observe annual yield variations in relation to prevailing weather conditions. Aside from supplying information regarding the physiology of this crop, the data are of interest to the corn grower because they indicate comparative yields, shelling percentages, moisture contents, and feed constituents at various stages of development. Some data also are presented concerning the effects of frost, drouth, day length, and the economic value of tillers and seminal roots.

Bulletin No. 341 - Rambouillet And Columbia-Rambouillet Lambs On The Range And In The Feed Lot, T. Donald Bell, Milton A. Madsen, James A. Bennett, Louis L. Madsen, D. Clarence Schmultz Sep 1950

Bulletin No. 341 - Rambouillet And Columbia-Rambouillet Lambs On The Range And In The Feed Lot, T. Donald Bell, Milton A. Madsen, James A. Bennett, Louis L. Madsen, D. Clarence Schmultz

UAES Bulletins

Sheep of predominately Rambouillet breeding have been most popular on southern Utah ranges because of their hardiness and wool-producing ability. In the early years of sheep production in Utah a major portion of the income was derived from the sale of wool. This situation has gradually changed over the past years and now income from the sale of lambs is greater than that from fleeces. Rambouillet rams with improved mutton qualities have been used by some range operators to increase the mutton producing abilities of their ewes. Other operators have used Corriedale, Panama, Columbia, and other white faced crossbred-type rams …

Aircraft In Agriculture, N. E. Shafer, J. D. Furrer, J. W. Lomax

Nebraska Agricultural Experiment Station: Historical Circulars

Airplanes were first used in agriculture shortly after the close of World War I. They proved valuable for locating mosquito breeding areas, for forest fire patrol work, as an aid in locating outlaw cotton fields in the campaign against pink bollworm, and for surveying damage caused in large forested areas by the spruce budworm.

The Growth-Promoting Properties Of Quinic Acid, Malcom Gordon, Francis A. Haskins, Herschel Mitchell Aug 1950

The Growth-Promoting Properties Of Quinic Acid, Malcom Gordon, Francis A. Haskins, Herschel Mitchell

Department of Agronomy and Horticulture: Faculty Publications

Evidence is accumulating that there is a common metabolic precursor to many of the benzene ring derivatives found in living organisms. Recent work by Davis and Tatum indicates that one such precursor is the naturally occurring shikimic acid (Fig. 1) since this compound serves as a growth factor for certain mutants of Escherichia coli and Neurospora which otherwise require a combination of tyrosine, phenylalanine, tryptophan and p-aminobenzoic acid for growth. These mutants cannot utilize the closely related, naturally occurring quinic acid (Fig. 1) as a substitute for any of their requirements.

The Influence Of Crop Plants On Those Which Follow V, Theodore Eugene Odland, Robert Smith Bell, John B. Smith Aug 1950

The Influence Of Crop Plants On Those Which Follow V, Theodore Eugene Odland, Robert Smith Bell, John B. Smith

Special Collections (Miscellaneous)

This is a study of the effect which crop plants have on the growth and yields of those crops which follow. The study began in 1907; this bulletin reports the results from 1930 to 1942. Millet, mangels and rutabagas generally seem to be harmful to crops which follow them. Carrots, mangels and millet were least favorable of all crops to mangels. Potatoes did poorest when following potatoes, rutabagas, or millet. Rutabagas yielded low following rutabagas, mangels and millet. Onions were unfavorably affect by preceding crops of mangels, cabbage, or rutabagas. There is no simple explanation for the effect of crops …


Bulletin No. 340 - Adult Honey Bee Losses In Utah As Related To Arsenic Poisoning, G. F. Knowlton, A. P. Sturtevant, C. J. Sorenson Aug 1950

Bulletin No. 340 - Adult Honey Bee Losses In Utah As Related To Arsenic Poisoning, G. F. Knowlton, A. P. Sturtevant, C. J. Sorenson

UAES Bulletins

During 1947 the 55,000 colonies of honey bees in Utah produced approximately $545,000 worth of marketable honey and beeswax. In addition they pollinated most of the fruit, alfalfa seed, various vegetable and other seed crops. By 1949 the price of honey had declined to where the crop of honey and beeswax was worth $253,000, produced by 49,000 colonies of bees. The value of bees in Utah as pollinating agents to fruit and seed crops greatly exceeds the income received by beekeepers from bee products sold. Because agriculture receives such great benefit from bees, it seems reasonable that farmers who are …

Bulletin No. 339 - Consumer Demand For Peaches Of Varying Stages Of Maturity Jun 1950

Bulletin No. 339 - Consumer Demand For Peaches Of Varying Stages Of Maturity

UAES Bulletins

Studies of consumer demand for peaches of varying maturities were conducted in Kansas City, Oklahoma City, Minneapolis, and Milwaukee during the 1949 peach marketing season. In these tests standard Elberta peaches from Colorado and Utah were used primarily but occasionally when they were not available Elbertas from Idaho and Michigan were used. No Early Elbertas were used.

This study is designed to promote the orderly marketing of peaches and to expand their consumption, that returns to growers may be maintained or increased. The study is primarily concerned with consumer demand for degree of maturity of Colorado and Utah Elberta peaches. …
