1.This experiment was made to clear the effect of soil moisture upon the development of tillering rimordium and tillering but in rice seedlings. 2. The percentage of soil moisture used were four, 50-60%, 70-80%, 90-100% of the water capacity in the soil and flooded condition. 3. In the first tillering primordium and tillering primodium and tillering bud, the dffects of soil misture on their developments was not observed too much among the separate plots in field-condition, however, their developments in flooded plot was remarkably inferior to comparison with the separate plots in field-condition. 4. In the second tillering primordium and eillering bud, their developments in the first-stage of growing were best at 70-80% plot and were bad at flooded plot, but as the growth progresses they result in best developments at flooded plot, that is, according to increase of soil moisture the tendency of improved growth was observed clearly. 5. On the 3rd, 4th, 5th, 6th, etc, of tillering primordium and tillering bud, with increasing of soil moisture they result in best developments.
