Seedling Establishment Of Alfalfa Comparing Four Varieties, Three Fungicides And Two Inoculums, Ronald Brown Foster

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The establishment of alfalfa is expensive and good initial stands permit the farmer to secure high yields and spread establishment costs over several years, Of the factors involved: seedbed preparation, fertilization, seed viability, method of planting, and water application are controlled by the farmer, On the other hand, beneficial and detrimental microflora are not so easily controlled because practices aimed at controlling the detrimental microflora may also destroy the beneficial.

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.

A Cytological Study Of The Induced Octoploid Of An Agropyron-Hordeum Hybrid, R. Bruce Ashman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The occurrence of hybrids, both interspecific and intergeneric, is frequent in the Gramineae generally (Stebbins, 1949), and is especially common in the tribe Hordeae of which both A. trachycaulum and H. jubatum are members. Intergeneric hybrids in this tribe have been studied by Stebbins et al. (1946a, and 1946b), Stebbins and Walters (1949), and Stebbins and Singh (1950) in an effort to determine true phylogenetic relationships on which to base a taxonomic classification, and results of these studies have indicated that the current taxonomic treatment of this tribe is highly artificial. Attempts to produce a perennial wheat and improve …

The Washita Group In The Valley Of The Trinity River, Texas: A Field Guide, Bob F. Perkins, Claude C. Albritton Jr.

Fondren Science Series

Our present understanding of Washita biostratigraphy in the north Texas area is founded upon the pioneer work of W. S. Adkins, W. M. Winton and Gayle Scott. Their work was published from about 1919 to 1932, and as is inevitable many of the outcrops studied by them are no longer accessible and several new exposures have added to our knowledge of the local biostratigraphy. It is the purpose of this field guide to acquaint geologists with those localities which are now accessible and which typify Washita stratigraphy in Tarrant and southern Denton counties.

The Use Of Saline-Soluble Tissue-Proteins In Systematic Serology, William B. Stallcup

Field and Laboratory

In recent years the emphasis of taxonomic studies in many animal groups has been at or near the species level, with often little done to clarify the relationships of the higher taxonomic units. This was either because it was felt that these units needed no revision, or that there was not enough new information at hand to warrant any revision. In many cases, groups of genera have been placed in a family simply because of some superficial resemblance.

Bulletin No. 374 - Fertilizer Reuirements Of Alfalfa Hay In Utah, R. F. Nielson, J. P. Thorne, G. T. Baird

UAES Bulletins

This bulletin is a report of one phase of research in agronomy. What is agronomy? Agronomy is the science of crop production and soil management and includes a scientific study of all phases of soils and soil conservation, irrigation practices, fertilizer usage, crop rotations, plant breeding, selection and management of new crop varieties, weed control, and other practices that lead to increased production of better quality crops.

Optimization Of A Kraft Pulp Dioxirane Bleaching Stage, Eric A. Thompson

Paper Engineering Senior Theses

This research characterized and optimized the bleaching potential of dimethyldioxirane (DMD) on an -oxygen-delignified hardwood kraft pulp. The DMD wash produced in-situ using a caroate (2KHSO₅^.KHSO₄^.K₂ SO₄) acetone under controlled conditions. The studied variables included chemical concentration, consistency, temperature, reaction time, and chelation. Statistically designed experiments with response surface, methodology were used - to help locate the optimum conditions with respect to pulp brightness and strength. These conditions were located at 2.8% AO (activated-oxygen charge), 5.5% consistency, and 55^° C.

It was found that over 95% of the total brightness …

Bulletin No. 1, The Dallas Seismological Observatory, January 1-March 31, 1954, Edward L. Hazelwood, Louis V. Hull, Harriss Laramore

Field and Laboratory

Since this station is comparatively new and the personnel relatively untrained, the following system was used in preparing these data. The USCGS H times and deltas, measured on a large, inaccurate globe, were used in conjunction with Gutenberg time-charts to identify each phase. The identifications were made by Edward L. Hazelwood and are as accurate as this method will permit.
