| Outline of Final Research Achievements |
We aimed to develop a crop cultivation technique using nitrogen-fixing bacteria (NFB) isolated from yams. In this study, 22 species of NFB of 18 genera were isolated from yams. The isolated NFB Rhizobium sp. was presumed to be a new species specialized for endogenous to yams. As a result of inoculating the isolated Agrobacterium sp. To a water yam (a kind of yam), the weight of the tuber and the nitrogen content of the leaves increased. As a result of the meta 16S analysis of the bacterium, the bacterium of the yam was mainly Proteobacteria of 5 genera. Proteobacteria is might related with yam growth. Furthermore, when upland rice was inoculated with each of the five types of bacteria, some bacteria had the effect of promoting growth.
