Sampling Studies In Morning Glory Roots, Lowell W. Rasmussen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Farmers and agriculturalists have in recent years become more conscious of the seriousness of the weed problems. The solution of this problem is obviously the development of more efficient and less costly methods of eradication. Most pernicious weeds are propagated vegetatively by means of underground parts in which reserve food is stored as a source of energy in tiding the plant over winter and initiating spring growth each year. In order to get at the behavior of these perennial parts, it is necessary to resort to a study of root reserves. This involves information not only on the composition of …

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 …

Control Of The Chinch Bug In Nebraska, M. H. Swenk, H. D. Tate

Nebraska Agricultural Experiment Station: Historical Circulars

The chinch bug, Blissus leucopterus (Say), is one of the most injurious insect pests of cereal crops in the United States. Although some damage by it has occurred over a wide area in the United States, the greatest injury has been in the Corn Belt. The years in which the chinch bug appears in destructive abundance come irregularly in cycles of varying duration, and the length of these cycles is largely controlled by the direct or indirect effects of weather upon the bugs. Continued dry weather favors them, while very wet weather brings about their destruction. During the last seven …

Grain Prices Received By Farmers Fob Chamberlain, South Dakota, Weber Peterson

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

The series of grain prices here presented are calculated from records of terminal market prices by deducting freight charges. In the absence of actual historical local price data this will serve many of the same purposes, subject to the limitations discussed on the inside back cover page. People interested in agriculture and efficient farming are very much concerned about prices. Unlike producers of branded products, farmers have been unable individually to control market prices through control of production. Since individual farmers have found that, in general, prices have been determined by forces beyond their control they have attempted to increase …
