Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …

The Relative Saponin Content Of Alfalfa Varieties In Utah As Measured By Chick Growth Depression, Morris Dean Wilding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bloat among ruminants is not new to farmers or scientists. One learns from a Roman author's description of this ailment written in 60 A. D. that the symptoms have changed little since that time. Literature also records that the treatments used today for the prevention and relief of bloat are similar to those prescribed by the early Romans (Anonymous 1954).

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The United States produces about 1.8 million tons of sugar annually. Approximately 75 per cent of this production is derived from sugar beets. The importance of the sugar beet crop in national and world economy is justification for research effort as a means to more economical production.

It is desirable that sugar beet processing be carried out in the most efficient manner. More effective utilization of the sugar beet and its by-products will add stability to the sugar beet industry.

For the past 170 years, since Achard found that sugar could be used for human consumption and that pulp might …

Bulletin No. 382 - Grass-Legume Mixtures For Irrigated Pastures For Dairy Cows, George Q. Bateman, Wesley Keller

UAES Bulletins

Pastures have been important in the agricultural economy of the Intermountain Region. But as long as nearby valley bottom or other land not well suited for cultivation was available, the pressure for better irrigated pastures remained secondary to that for improved cash crops.
Only in recent years have dairymen generally realized that a productive herd, coupled with proper management, could make a good pasture a highly profitable crop. Bateman and Packer pointed out in 1945 this concept of pastures. Bateman et al. using newer mixtures strikingly verified the concept in 1949 and 1954. The growing awareness of the value …

Bulletin No. 383 - Cooperative Nutritional Status Studies In The Western Region: I. Nutrient Intake, Ethelwyn B. Wilcox, Helen L. Gillum, Margaret M. Hard

UAES Bulletins

In 1947, a concerted study of the nutritional status of selected population groups was initiated in the western region of the United States. Previous dietary surveys had indicated that substantial portions of the country's population were consuming lower than recommended levels of essential nutrients. Deficiency diseases that may have nutritional background, such as dental caries, anemia, and rickets, existed. Investigators reported subclinical signs of malnutrition in several areas. Few studies had been made in the West, although reports of high incidence of dental caries and suspected undernutrition had come from several western states. The regional committee thought it evident that …

Bulletin No. 384 - Virus And Viruslike Diseases Of Stone Fruits In Utah: A Handbook For Their Identification And Control, B. L. Richards, L. C. Cochran

UAES Bulletins

Intensive research over the last 20 years has shown that many of the previously unexplained and seemingly mysterious disorders of stone fruit trees in Utah are infectious diseases caused by viruses. Others were shown to be the result of noninfectious genetic abnormalities or of adverse chemical and physical factors in the environment of the plant. The purpose of this handbook is to help orchardists and others recognize these diseases and disorders and understand better their etiology or cause. The handbook will also bring together basic information which will aid in their control.

The Effects Of Antibiotics Aureomycin And Terramycin On The Disease Crown Gall In Tomato Plants, Charles Raymond Anderson

Dissertations and Theses @ UNI

The disease crown gall manifests itself on various woody or herbaceous plants by the formation of tumor-like enlargements at the crown or on other parts or by extensive production of organs (roots, shoots). In both cases the abnormal development is an uncontrolled hyperplast, resulting in tumors or galls of varying sizes and form or in the production of organs, frequently out of normal position and in excessive numbers. Because of the frequent location of the galls on the stem or trunk near or at the ground level, the disease has been known as crown gall. Various other names such as …

Tannin Content Of English Walnuts : Thesis ..., Joseph G. Natoli

University of the Pacific Theses and Dissertations

Present methods for the production of leather from animal hides still depend from the most part on the use of natural tannin extracts. During the year, 1952, the amount of natural tannin extracts used by the leather industry was 560,452,119 pounds as compared to 35,793,000 pounds of synthetic tanning materials. It is not as yet possible to produce synthetic materials as economically as the natural extracts; the result being that there is still a very great demand for natural tannin extracts. The need for finding new domestic sources of tannins is apparent when the amounts of domestic and imported extracts …

Performance testing has recently been advanced as a means of identifying individuals possessing superior productive qualities and as a means of evaluating sires for transmitting these qualities to their offspring. This report gives the results of performance tests conducted with Hereford and Shorthorn calves fed over a constant time period as well as the results of a supplemental study undertaken to gain information that might add refinement to the evaluation of gains in beef cattle.

Phenotypic Variations Of Kochia Scoparia, Kenneth Malcolm Benson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Kochia scoparia (L.) Schrad. has had limited use as a forage crop during the past fifteen years in parts of the western United States, Canada, and Argentina. Erickson and Moxon (1947) reported kochia* to be a good emergency feed for sheep and cattle during dry years in South Dakota. Salguero (1946) said that this species could be utilized in Argentina as silage or pasturage if harvested before flowering. Bell, et al. (1952) in Saskatoon, Canada studied this species in a comparison with other introduced plants and reported that it seemed to have desirable nutrient characteristics for livestock roughage. Plummer …

Detection Of Coumarin In Seeds Involving Crosses Between Two Species Of Melilotus, William H. Davis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sweet clover has become increasingly important as a forage and green manure crop. The main objection in recent years to sweet clover is its coumarin content, identified by a sweet odor and bitter taste, making it less desirable to farm animals. When sweet clover hay spoils, the coumarin is converted into dicoumarol which is toxic to animals, especially to ruminants. When ingested this may cause internal and/or external hemorrhages.

Managing Farm Fishponds For Bass And Bluegills, Verne E. Davison

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A Fishpond is a delightful part of a farm or ranch. Where a good site exists for a pond, it makes good use of the land. The impounded water often has other uses too. It adds beauty to the farm and provides recreation for farmers, ranchers, and their friends.

Fishponds are profitable when they are managed well. To produce the most income and home use, they must afford good fishing year after year. Most disappointments result from mistakes in management.

This bulletin points out the importance of good sites and the necessity for erosion control, proper stocking, and weed control. …
