Abstract:: Agronomic and microbiological studies were conducted on "Anchor" alfalfa (Medicago sativa L.) established from uninoculated seed on three Aridisols in central Oregon. Significant responses to 230 Kg N per ha (NH₄NO₃), which was applied in mid-April and after each first and second harvests, were observed in yield parameters of the...

Abstract:: This thesis presents novel findings regarding symbiotic, physiological, and antigenic characteristics of representatives from an indigenous soil-borne population of Rhizobium meliloti. Nodules were sampled from 'Vernal', 'Anchor', and 'Saranac' alfalfa, and the isolates analyzed serologically. Rhizobium meliloti serogroup 31 was identified as a dominant nodule occupant, with a greater and...

Abstract:: Complementary methods of strain identification were sought to delineate the composition of the population of Rhizobium trifolii found in nodules of Trifolium subterraneum L. when exposed to an Abiqua silty clay loam (Cumulic Ultic Haploxeroll) containing a resident population of R. trifolii. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDSPAGE) was...

Abstract:: Previous research had identified four serogroups of Rhizobium trifolii indigenous to Abiqua soil (fine, mixed, mesic, Cumulic Ultic Haploxerolls). Nodulation of subterranean clover (Trifolium, subterraneum L.) by two of the serogroups, 6 and 36, was influenced by the application of CaC0₃ to the soil. The studies described in this thesis...
