Synopsis Effective strains of rhizobia to inoculate Kura clover ( Trifolium ambiguum ) were isolated from nodules on T. spadiceum , T. ochroleucon and from nodules on T. ambiguum produced with enrichment cultures prepared with six different soil samples. These soils and the nodulated specimens were all from the same general locality in Turkey. In greenhouse sand cultures 21 strains gave yields which were significantly better than the uninoculated controls. In greenhouse soil cultures with five soils, an overall comparison of the uninoculated plants with the inoculated plants showed a highly significant increase in dry weight and nitrogen content brought about by the inoculation.
