| Outline of Final Research Achievements |
Two bacteria of high IAA production activity had been isolated from soybean rhizosphere. One was identified as Microbacterium genus, the other was identified as Cronobacter genus. These two bacteria suspension coated (soaked for 5 minutes) to the seed just before the soybean two variety seeds (Enrei and Sachiyutaka), there were sown in the field.
Both bacteria were confirmed that not give bad influence to the emergence rate.The yield of soybean coated with Microbacterium genus as compared to the control, increased 46% in Enrei and 16% in Sachiyutaka , respectively. On the other hand, the yield of soybean coated with Cronobacter genus were reduced. It is a simple method of coating the microorganisms to the seed, but it was revealed that the effect of increasing the yield of soybean.
