This study investigated the effect of various waters on rice plant hydroponics. Tap water (Kumamoto city) had a significant influence on rice plant growth. Compared with distilled water, tap water suppressed plant length. Water treated with calcium rich Granite (Tetsuta village in Okayama) for 3 days effected the number of tillers and young panicles. The treated water was pH8.3 and showed electric conductivity (EC) 30 μS/cm and Oxidation-reduction potential (ORP) 232 mV. The quantity of starch synthesis significantly differed between plants grown with distilled water and those grown with the treated water. These results suggest that changes in water quality affect photosynthesis.
