| Outline of Final Research Achievements |
The purpose of the present study is to clarify the effectiveness of crack fertilization that is the new technique to enhance soybean yield by the application of nodule bacteria to soybean just before flowering. In addition, we conducted at two different region of Hokkaido and main island of Japan (Shiga and Nara prefecture) to evaluate that the technique is useful in all region of Japan. In cold region of Hokkaido, soybean yield did not increase by the technique compared with the control. In the main island, however, soybean yield in an upland field and an upland field converted from a paddy increased by the application of the technique. The application of charcoal into the crack between rows just before flowering was effective to increase soybean yield in an upland, and the application with nodule bacteria below rows before sowing significantly increased soybean yield in an upland converted from a paddy.
