Varieties And Quality Of Small Grain Seed Planted In Utah In 1958, Louis A. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

High quality seed is of first importance in efficient crop production. Seed is one of the major factors affecting yield and quality of the crop. High quality seed is of adapted varieties, has high gemination, and is free of foreign material and weed seeds. Crop seed containing weed seeds may be the means of infesting farm land with weeds. Such seed is expensive at any price.

Studies On The Relationship Of Moisture Content To Threshability And Viability Of Pea Seeds, Filixberto Roquia Y Dulalas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When in commercial practice seed peas (Pisum sativum) are harvested, the vines are cut and windrowed or bunched and allowed to cure for a week or longer, depending upon the moisture content of the crop and weather conditions. The sooner the crop can be threshed, the less is the chance of loss caused by rain and the often-necessary attendant operation of turning the windrow or bunch to facilitate drying. In general, growers wait until the vines, pods, and seeds are quite dry. To what extent this is necessary is not known.

The Effect Of Feeding Various Levels Of Fluoride To Dairy Cattle On Their Pepsin Activity, Hassan Sabeti-Rahmati

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In certain industrial areas fluorides are present in various amounts in the atmosphere. These fluorides are liberated by industrial processes at high temperature in treatment of materials containing fluoride, either as a natural impurity, or as added material for technical purposes. Equipment and procedures have been installed in many plants to reduce the output of fluorides significantly, yet forage and hay grown near the plants may contain elevated amounts of fluorides. The feeding of such material to young livestock for many months may cause fluorosis or chronic fluoride poisoning. Some springs contain a high concentration of fluorides and the continuous …

A Study Of Hot Brine Treatment In Making Cheese From Antibiotic Milk, Robert E. Howe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The cheddar cheese industry is continually confronted with the problem of manufacturing cheese from milk in which tile acid development is slow or non-existent. In recent years, many antibiotics have been used as a treatment for mastitis. Penicillin, streptomycin, and aureomycin are some of the more prominent antibiotics used for this purpose.

The Inhibitory Effects Of Tarweed Upon The Germination And Growth Of Seedlings, Glenn F. Carnahan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extensive areas of potentially productive but depleted range land in the United States are occupied by a weed commonly known aa cluster tarweed (Madia glomerata). Moat attempts at seeding these areas to useful forage plants have resulted in failure. Many of these failures have been attributed to the vigorous competitive growth of tarweed plants. More recent observations of seedings in tarweed areas and laboratory work at the University of Utah indicate that tarweed is not only a strong competitor but may also produce substances which inhibit the germination and growth of other species of plants.

Influence Of Moisture And Nitrogen Levels And Harvest Interval On Water Requirement Of Two Genotypes Of Orchardgrass, William W. Wagner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the semi-arid west, moisture is often the limiting factor in plant growth. High crop production is dependent upon rainfall and supplemental moisture supplied through irrigation. Plants for these areas, which are most efficient in use of water, other things being equal, would be more desirable.

Relationship Of Certain Environmental Factors To Benthic Fish Densities In Bear Lake, Idaho-Utah, Thomas J. Hassler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The project was initiated in June of 1958 and financed by the National Science Foundation and the Wildlife Management Department of Utah State University.

The broad aspects of the study were to determine if a relationship exists between certain physical and biological factors and benthic fish densities. The project vas divided into two parts: (l) to determine the time and extent of thermal stratification, zooplankton densities, conductivity changes within the lake and conductivity differences between the lake and its tributaries; (2) to determine it a relationship exist between benthic fish densities, temperatures, depths, conductivities and benthic zooplankton densities. The data …

Observations On The Life History Of Channel Catfish, Ictalurus Punctatus (Rafinesque) In Utah Lake, Utah, Robert E. Lawler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The channel catfish, Ictalurus punctatus (Rafinesque), was first introduced into Utah Lake in the summer of 1911, and has since been stocked in the lake on numerous occasions. It has only been in the last few years that the channel catfish has become an important game fish in Utah. As the value of the channel catfish, as a game fish, increased, it has become increasingly important to the state to maintain this species for present and future generations. This study was initiated in 1958 and completed in 1960, and was financed by the Utah State Department of Fish and Game. …

East Texas: A Timbered Empire, Edwin J. Foscue

Journal of the Graduate Research Center

The forest-covered portion of East Texas, with an area of approximately 28,000 square miles, is larger than Vermont, New Hampshire, and Massachusetts combined (Fig. 1). The timbered region, which represents about one-eighth of the total area of the state, has contributed so much to the history and economic development of Texas that it deserves to be better known.

4-H Demonstrations And Illustrated Talks, Ima Crisman

SDSU Extension Circulars

You give a demonstration to help others learn how to do something useful in their home or in the family business and how to do it the easiest and most practical way. Demonstrations help you, too. You learn to talk easily while you use your hands to show a useful practice. You find out a lot about the subject you demonstrate.

Insect Pollinators Of Carrots In Utah, George E. Bohart, William P. Nye

All PIRU Publications

IN THE course of observation at Logan, Utah, on the occurrence and pollinating activities of insects on carrots grown for seed, 334 species representing 71 families, were collected. Most numerous in species were the hymenopterous families and superfamilies Sphecidae, Apoidea, Psammocharidae, Vespidae, and Ichneumonidae, and the dipterous families Syrphidae, Tachinidae, Bombyliidae, Stratiomyidae, and Sarcophagidae. Most numerous in individuals were the dipterous families Syrphidae, Ceratopogonidae, Chloropidae, and Piophilidae and the coleopterous family Coccinellidae. Families and superfamilies represented by the most efficient pollinators were Apoidea, Sphecidae, Syrphidae, and Stratiomyidae. Abundance times efficiency was used as a pollination index for each species. On …

A Quantitative Study Of Sexual Behavior Of Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

In recent years an increased interest in the use of behavioral characteristics in evolutionary studies has developed, and this is particularly true in the case of waterfowl. The classical studies of Heinroth (1911), who was one of the first to apply knowledge of waterfowl behavior to systematics, have been elaborated on by Lorenz (1941; 1951-1953) in his important contribution toward the understanding of relationships in the Anatinae. These, and other, studies have stressed the qualitative behavioral differences occurring among different species as providing possible isolating mechanisms through their presumed function of conveying species-specific recognition signals. To the present, no extensive …
