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 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...

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...

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...

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...

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)...

The role of plastic mulch as a water conservation practice for desert oasis communities of Northern China

Creator:: Ingman, Mark Christian
Abstract:: China's Minqin Oasis once welcomed traders along the ancient Silk Road with rivers, lakes, and lush forests, yet today the region's farmland and grassland are increasingly being engulfed by the sands of the Gobi Desert. The severity of this incremental catastrophe for a declining population of 300,000 residents has brought...

Osmotic stress vigor test for wheat seed

Creator:: Currans, Sean
Abstract:: Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...
