Relative Efficiency Of Roots And Tops Of Plants In Protecting . The Soil From Erosion, Joseph Kramer, J. E. Weaver

Papers of John E. Weaver (1884–1956)

An increasing realization of the importance of preventing or controlling soil erosion has resulted in numerous scientific investigations. Some of these are concerned with soil characteristics which promote or retard erosivity (Middleton, '30; Middleton et al., '34; Lutz, '34; and Bouyoucos, '35). Many have to do with engineering methods of reducing soil wastage (Bates and Zeasman, '30; Ramser, '30; Roe, '33; and Bartel, '35). But perhaps most were planned to discover the effects of plants in protecting and binding the soil, reducing runoff, and consequent loss of soil and subsoil (Sampson and Weyl, '18; Duley and Miller, '23; Lowdermilk, …

Index Numbers Of South Dakota Farm Prices, Leslie Max Brown

Electronic Theses and Dissertations

During the last generation, index numbers have gradually gone into general use among economists, statisticians, and business men. Because a farmer is a business man, it is important that he know what the trend of farm prices have been in the past and what the current trend is, so that he may anticipate changes which statistical analysis show are taking place in his particular phase of business.The Main objective of this study is to revise the existing South Dakota Farm Price Index. In order to furnish a comparable background for the presentation of these results it was found desirable (1) …

The Abortion Of Essential Organs In The Imperfect Flowers Of Benzoin Aestivale, Norris M. Paulson

Electronic Theses and Dissertations

There have been a number of investigations dealing with the abortion of essential organs in the imperfect flowers. Ulvin submitted a paper on Abortive Stamens and Carpels in Lychnis alba, Simon described stamen and carpel abortion in Cucumis stativus, Schaffner was able to control sex expression in Arisamea triphyllum and secure sex reversal in Cannabis stiva, Bessey determined the relationship of sex to the age of pollen in Cannabis sativa.

An Analysis Of Crop Production In South Dakota By Types Of Farming Areas, Warren Richards Bailey

Electronic Theses and Dissertations

Farmers choose the crops they grow for two principal users; namely, for feed production or for cash income, or for both feed and cash income. It is true that some crops are grown for cover-crops, soil building, weed competition and a multitude of other miscellaneous purposes, many of them of equal or greater importance in the individual case than the two uses of crops which are the basis for this analysis. Crop production in South Dakota has been discussed since the first records of yields were available. the usual unit for production was the legal bushel of a specified weight.

Observations On Thinning And Management Of Eastern White Pine (Pinus Strobus Linnaeus) In Southern New Hampshire, Ralph C. Hawley

Yale School of the Environment Bulletin Series

In October, 1905, several permanent sample plots were in the white pine type near Keene, New Hampshire, by the United States Forest Service in cooperation with the Faulkner and Colony Manufacturing Company on lands owned by the latter. The purpose of the investigation was to study some effects of thinnings and of partial (shelterwood) cuttings for establishing natural regeneration. The plots were remeasured in 1909 and again in 1915 by representatives of the United States Forest Service, but after the 1915 measurement they were turned over to the Yale School of Forestry.* In 1920, 1925, 1930, and 1935 the plots …

Factors Controlling Initial Establishment Of Western White Pine And Associated Species, Irvine T. Haig

Yale School of the Environment Bulletin Series

The principal object of the study was to determine the roles played by important physical factors of site, chiefly as these vary with overhead shade and hence are within the control of the silviculturist at the time of logging. No special effort was made to study the effect of biotic agents under natural conditions. Indeed, in order to insure as large a sample of seedlings as possible on which to follow losses caused by physical factors, biotic agents were discouraged wherever feasible. But as records of all mortality losses were kept by cause, some information was collected on the activity …

The Tympanis Canker Of Red Pine, John Raymond Hansbrough

Yale School of the Environment Bulletin Series

A new disease of red pine has recently been found in southern Connecticut, Rhode Island, eastern Massachusetts, western and central New York, northern New Jersey, eastern Pennsylvania, central Ohio, and southern Michigan. It is of serious consequence only on plantation-grown red pine, but it also occurs occasionally on eastern white pine. On the former host it is characterized by axially elongated, annual main-stem cankers which are always centered at the nodes. Infection takes place through adhering lateral dead branches and the growth of the fungus after it gains entrance to the stem.is usually very rapid-Le., cankers up to three feet …

Bulletin No. 258 - Alfalfa-Seed Investigations In Utah, John W. Carlson

UAES Bulletins

For many years alfalfa-seed production problems have engaged the attention of investigators in various parts of the world. Those factors which are regarded as of greatest importance in seed-setting are general climate, current weather, air humidity, soil moisture, and insect relationships within the various alfalfa-seed districts. Some attention in research has been given to pollen fertility and ovule sterility, as well as to general flower dynamics in relation to environmental conditions. Efforts have been made to develop strains of alfalfa having pollen that is resistant to injury by moisture or having self-tripping flowers or autogamous strains of alfalfa whose flowers …

Bulletin No. 263 - Relative Produciton Of Feed Grain From Spring-Grown Cereals In Utah, R. W. Woodward, D. C. Tingey

UAES Bulletins

Nearly one-third of the cropped acreage of Utah is devoted to cereals. Except for wheat, most of these crops are fed locally. In addition to this, an average of over a million bushels of corn, barley, and oats is shipped into the state each year to be used in various livestock and poultry industries.

The purpose of this publication is to show the comparative amount of feed produced by the different crops--wheat, oats, barley, and corn--under similar conditions as determined for the specified four years by acre-yields obtained in various agricultural regions of the state. One should bear clearly in …

Bulletin No. 260 - Oat Varietal Tests In Utah, R. W. Woodward, D. C. Tingey

UAES Bulletins

The United States Census Report for 1930 shows that approximately 25 per cent of Utah farmers were growing oats at that time. Leading counties in oat production were Sanpete, Utah, Emery, Cache, and Weber, each of which produced over 100,000 bushels. Sanpete County produced over 200,000 bushels, whereas Boxelder, Sevier, Duchesne, and Salt Lake Counties produced slightly less than 100,000 bushels each.

Bulletin No. 261 - Barley Varietal Tests In Utah, R. W. Woodward, D. C. Tingey

UAES Bulletins

In 1929 approximately one-fourth of the farmers of Utah were growing barley, with an average of 6.3 acres to the farm. Cache, Sanpete, Sevier, and Utah Counties each produced over 100,000 bushels. According to the United States Fifteenth Census Report (1930), Davis, Millard, Morgan, Rich, Salt Lake, and Weber Counties each produced from 40,000 to 70,000 bushels.

Bulletin No. 262 - Comparative Yields Of Spring Wheat Varieties In Utah, D. C. Tingey, R. W. Woodward

UAES Bulletins

Wheat was one of the first crops grown by early Utah settlers. It has since occupied an important place in the agriculture of the state. While wheat is almost the only crop grown successfully on dry-lands, it is also important under irrigation. Thirty per cent of the wheat acreage of Utah in 1929 was spring-sown, which produced 44 per cent of the state's production. Eighty-seven per cent of the spring wheat acreage was grown under irrigation, this acreage producing 92.3 per cent of the total spring wheat crop. Thirty-eight per cent of Utah farmers were growing spring wheat in 1929; …

Bulletin No. 264 - Relief Wheat, D. C. Tingey, R. W. Woodward

UAES Bulletins

Relief, a new variety of hard red winter wheat resistant to most forms of covered smut occurring in Utah, was bred by the Department of Agronomy, Utah Agricultural Experiment Station. Produced by hybridization, it resulted from a response to an urgent need for some more effective means of controlling the serious disease of wheat known as covered smut or bunt. In addition to being resistant to forms of covered smut which have caused such heavy losses to wheat farmers of central and northern Utah and southern Idaho, experiments have also shown that it appears equal in all other respects (such …

Bulletin No. 259 - Drainage Of Land Overlying An Artesian Groudwater Reservoir: Final Report, O. W. Israelsen, W. W. Mclaughlin

UAES Bulletins

This bulletin constitutes a final report of some phases of cooperative drainage studies in Cache Valley, Utah. The drainage problem in Cache Valley is typical, in many respects, of drainage problems in other irrigated valleys of Utah and the West in general. Application of the principles indicated by the problems will doubtless add materially to the productivity of the land in the several communities concerned and will also contribute to the advancement of public welfare in the general improvement of health, economic, and social conditions. Alkali and water-logging affecting large areas are causes not only of low productivity of the …
