This study was conducted to investigate how electrostatic field water treatment influences the growth and yield of tomatoes during hydroponic cultivation using a coir substrate. Electrostatic field water treatment is a method that achieves sterilizing and disinfecting effects by weakening the hydrogen bonding force through high voltage. The focus was laid on the tomato variety ‘Dandani’, which was cultivated for about 10 weeks. Arrangements of the test plots were divided into various treatments such as electrostatic field water treatment and general hydroponic cultivation. Inorganic ion content during growth, fruit supply, and drainage and the ion content of each plant organ were analyzed. The results show an increase in the leaf length of treated plants by 9.54% and the leaf area by about 24.3% compared to the control group. No difference was observed in the fruit set rate nor in the fruit characteristics, but the navel rot was reduced by 1/3 (11.56% in the control group and 3.52% in the treatment group). This was confirmed by the difference between drainage content and liquid supply. This study suggests, that using electrostatic field water treatment in tomato circulation type hydroponic cultivation potentially reduces calcium deficiency during the rainy season.
