Effect of nitrogen fertilization of wheat (Triticum spp.) on chemical and biochemical composition and performance of seeds

Creator:: Garay, Adriel Edgardo, 1945-
Abstract:: High protein wheat seeds frequently perform better than low protein seeds of the same variety. Protein content of seeds can be increased by management practices, the most important of which is rate and timing of N applications. The purpose of this study was to determine the chemical, biochemical and physiological...

A study to determine the need for mathematics inservice training for untrained and trained teachers in K-7 rural schools in Manicaland, Zimbabwe

Creator:: Makande, Tendekai Don
Abstract:: The purpose of this study was to determine the need for mathematics inservice training for untrained and trained teachers in K-7 rural schools in Manicaland, Zimbabwe. The auxiliary teachers do not have any professional preparation before entry into the teaching profession. The study sought to determine the mathematics areas needed...

Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...

Nutritional factors associated with the presence and growth of Klebsiella in redwood environments

Creator:: Talbot, Henry Wilkinson
Abstract:: Bacteria of the genus Klebsiella have been found to be associated with redwood water storage reservoirs, redwood chips, and liquid expressed from within living redwood. A 1,000 gallon experimental redwood reservoir was employed to determine how to control the presence of Klebsiella and Enterobacter in drinking water stored in these...

Traditional ecological knowledge of Siletz tribal members

Creator:: Hatfield, Samantha Chisholm
Abstract:: This research effort examined Traditional Ecological Knowledge (TEK) of Siletz tribal members of the environment they live and/or lived in, and how both Western societal beliefs and land reduction to the initially established reservation location affected and altered how the area TEK has been maintained and passed down. The theory...

Cytokinin production by Agrobacterium tumefaciens

Creator:: Kaiss-Chapman, Richard Wilkinson
Abstract:: Certain plant-associated prokaryotes such as Corynebacteriurn fascians and Agrobacterium tumefaciens are known to produce substantial levels of cytokinins. In view of the fragmentary and presumptive evidence available on the quantitative and qualitative levels of cytokinins produced by A. tumefaciens, it was decided to conduct a study of the cytokinins produced...

Spring establishment of orchardgrass and tall fescue seed crops with cereal companion crops

Creator:: Chastain, Thomas G.
Abstract:: Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to...

Effect of sheep grazing on subterranean clover (Trifolium subterraneum L.) seed production

Creator:: Steiner, Jeffrey John
Abstract:: Subterranean clover (Trifolium subterraneum L.) seed production practices in Oregon are different from those in Australia. There, seed is produced on fields which are managed primarily for forage. In Oregon, seed fields are managed for seed as the primary product and forage is of secondary concern. Some sheep grazing is...

Developing a basis for characterizing precision of estimates produced from non-probability samples on continuous domains

Creator:: Cooper, Cynthia
Abstract:: This research addresses sample process variance estimation on continuous domains and for non-probability samples in particular. The motivation for the research is a scenario in which a program has collected non-probability samples for which there is interest in characterizing how much an extrapolation to the domain would vary given similarly...

Effect of moisture stress on yield and quality of winter wheat seed

Creator:: Assuncao, Marcos Vinicius
Abstract:: Two experiments were conducted to determine the effects of moisture stress on physiological changes that occur during the vegetative and reproductive stages of the wheat (Triticum aestivum L.) plant, and to relate these effects to seed yield, quality and performance. In a field experiment, different levels of moisture stress were...
