1. Hill distances of Japanese radish in single seed sowing method were 4, 6 and 8cm for controlling vacant hill and adjusting to 24cm which is standard distance by thinning.2. Vacant hill rate in single seed sowing method was about 5%, and was about 2% in three seed sowing (control).3. Thinning operation time of single seed sowing method for adjusting hill distance to 24cm was about 85% of the control.4. Growth of the radish indicated smaller depend on the decrease of hill distance, and was smallest in the control.5. In the thinning of the radish from 8cm to 24cm distance, the distance was adjusted to 16cm at the vacant hill happened, however growth difference was not significant.6. These results indicate that one seed sowing of 8cm distance is the most advantageous on the yield of radish and on the labor saving for the thinning.
