The effect of preplant nitrogen fertilization and soil temperature on biological nitrogen fixation and yield of alfalfa (Medicago sativa L.)

Creator:: Shuler, Philip E.
Abstract:: The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa...

The China Connection : A Glimpse of Collaborative Research Between China and Oregon State University

Creator:: Kenny, Kimberly
Abstract:: China’s global influence in the realm of science and technology (S&T) has increased dramatically in recent times. China and the United States are now each other’s main partner in scientific collaboration. As a major research university, OSU is one of the institutions with a large stake in this international collaboration....

Selection for Persistence in Red Clover through Improved Tolerance to Northern Anthracnose [NA; Kabatiella caulivora (Kirch.) Karak.] and Drought

Creator:: Sahin, Muhammet
Abstract:: Twenty-three red clover cultivars and accessions were grown in Boyd, KY, and Philomath, OR to evaluate their tolerance of northern anthracnose [NA; Kabatiella caulivora (Kirch.) Karak.] and drought, dry matter (DM) production, and their agro-morphological characteristics. The key research questions of this study were the influence of NA on yield...

Nitrogen nutrition of seedling alfalfa (Medicago sativa L.)

Creator:: Eardly, Bertrand D.
Abstract:: Nitrogen fertilization of seedling legumes is a controversial practice intended to provide N to the plant during periods when seed N, soil N, and N₂ fixation may not meet plant requirements; eg. prenodulation, postharvest, or in the event of an inoculation failure. Field experiments were conducted in 3 consecutive years...

Improving the Forage Species Selection Process through Research and Teaching Projects

Creator:: Randow, Brianna Lyn
Abstract:: Species selection is a complex process that forage producers and land managers face. Accurate tools and educational materials are needed to help make the decision process easier. Crop simulation models are one tool that could be utilized to predict yield and potential financial return of various species. Two crop simulation...

Evaluation of Rhizobium strains with three Mediterranean forage legumes for biological nitrogen fixation

Creator:: Streeter, Donald J.
Abstract:: Centuries of continuous grain cropping in northern Africa have reduced N levels in soils to a degree such that agricultural production is now largely dependent upon nitrogen fertilizer. Through the identification of highly effective legume and Rhizobium strain combinations, the production of protein-rich livestock forage and green manure can be...

Evaluation of a Rhizobium meliloti transconjugant for increased nodulation and biological nitrogen fixation in alfalfa

Creator:: Mao, Meiyu
Abstract:: Agrobacterium rhizogenes has been shown to cause root proliferation and increased water use efficiency in certain woody dicots. Root proliferation may be desirable in herbaceous legumes as a means of increasing potential sites for infection by Rhizobium species and subsequent nodulation and nitrogen fixation. Thus, A. rhizogenes was used to...

Effect of sulfur on dinitrogen fixation of alfalfa (Medicago sativa L.)

Creator:: Lopez-Jurado, Gerardo
Abstract:: Field experiments were established in 1982 and 1983 on a Woodburn silt loam soil (Aquultic Argixeroll) to examine the effect of S fertilizer on dinitrogen fixation and dry matter yield of 10 week-old seedling alfalfa (Medicago sativa L. cv. 'Apollo'). Six levels of S fertilizer (0 to 67.2 kg S/ha)...

Breeding for Improved Forage Yield Potential and Digestibility in Tall Fescue (Schedonorus arundinaceus (Schreb.) Dumort.)

Creator:: Sahin, Elif
Abstract:: Tall fescue is a perennial forage grass widely used in areas not well-suited to perennial ryegrass due to climatic or edaphic stressors including drought and low or high pH. Although tall fescue has many agronomic attributes that make it well suited to a wide range of environments, it is lower...
