Bulletin No. 300 - A Study Of Farm Organization By Type Of Farm In Sanpete And Sevier Counties, W. Preston Thomas, George T. Blanch, Edith Hayball

UAES Bulletins

This study is one of a series being conducted by the Department of Agricultural Economics which are designed to furnish a general description and a detailed analysis of the type of farming in various parts of Utah. The specific purpose of the general state-wide study is to: (1) locate and delineate the major type-of-farming areas of the state; (2) analyze and describe the major and some minor types of farming within each area; and (3) indicate the fundamental reasons for the principal differences which exist within and among these type-of-farming areas.

Upon the completion of the first part of the …

Bulletin No. 298 - Wool Scouring Tests In Utah, Alma C. Esplin, Ralph W. Phillips, Milton A. Madsen

UAES Bulletins

Wool, as it is shorn from the sheep, is known as grease wool. The first step in the manufacturing of wool is scouring, or removal of all grease and foreign matter. Within any given grade, as determined by length of staple and fineness of fiber, the yield of clean wool is the primary factor in determining the value of the original grease wool. The price of scoured or clean wool is multiplied by the percentage yield of clean wool to determine the value of the grease wool.

Bulletin No. 297 - Pale Western Cutworm, C. J. Sorenson, H. F. Thornley

UAES Bulletins

THE PALE WESTERN CUTWORM ( Agrotis orthogonia Morr.) has caused periodic damage to dry-farm grains in Utah during the past 25 years. In the spring of 1916, entomologists of the Utah Agricultural Experiment Station were asked to determine the cause of large bare spots occurring in fields of fall-planted wheat in the Indianola district of Sanpete County. A moderately severe infestation of pale western cutworm was found to be the causative agent. Pack reported that during the spring of 1929 this insect had inflicted serious damage to fall wheat at Fairview, Sanpete County.

Bulletin No. 299 - Control Of Chlorisis In American Grapes, F. B. Wann

UAES Bulletins

The production of grapes is not a major agricultural industry in Utah, but in some areas of the state the crop is an important adjunct to the general fruit farm. This is particularly true in Washington County where European (vinifera) varieties are grown with considerable success, and in the north central counties where American (labrusca) varieties, especially Concord, are grown for the local markets. In this latter area the nutritional disease, chlorosis, is probably the most serious difficulty encountered in the development of a successful vineyard.

Bulletin No. 296 - Uton: A New High-Yield White Oat Resistant To Loose And Covered Smuts, D. C. Tingey, R. W. Woodward, T. R. Stanton

UAES Bulletins

Oats have been among the five or six leading crops in acreage grown in Utah since its settlement. For many years Swedish Select has been by far the most predominant variety. This variety is well adapted to Utah conditions, but because of its high susceptibility to loose and covered smut, it is not the most desirable.

In 1934, after extensive trials, the variety, Markton, which is resistant to loose and covered smuts, was introduced into the state to replace Swedish Select. In those trials, Markton averaged 13 percent higher in acre yield than Swedish Select. Markton possessed one drawback in …

Bulletin No. 295 - Comparison Of Two Methods Of Determining Wool Density, Milton A. Madsen, Ralph W. Phillips, John V. Christensen, Roy L. Henrie

UAES Bulletins

Density of the fleece is one of the primary factors determining the wool-producing capacity of the sheep. Sheepmen have attempted to evaluate density by handling the fleece. This method is not sufficiently refined for use in experimental work, and may be subject to errors and misinterpretations. For example, if two fleeces are alike in density and diameter of fibers, yet differ in length, the longer fleece will feel less dense. If, on this basis, the sheep with the fleece that appeared most dense were selected for breeding, selection would be away from the longer fleece. Any method that can be …
