Acoustic emission (AE) was measured at the stem of a cherry tomato in spray culture, and the change ratio of AE before and after irrigation RD was calculated. The AE event rate highly fluctuated, and the number of detected AEs was insufficient to calculate RD at all times. However, the change in RD was negatively related to the increase and decrease in irrigation time for a short duration (less than 5 h), while the change of RD contrarily showed positive relationship with the irrigation time in a long term. Furthermore, the yield and sugar content of the fruits were related to the average value of RD. These results suggest that RD might improve the efficiency of tomato cultivation in a horticultural facility.
