This experiment was conducted to investigate the effects of diurnal altermation of nutrient solution salinity on growth and fruit quality of tomatoes (Lycoperisicon esculentum cv. 'House momotaro') hydroponically grown in root intercept bag-NFT(RIB-NFT) system. Plant height was the lowest in the high concentration during daytime (6/1 dSㆍm-¹, day/night). Yield was very high in the concentration of 1/1 dSㆍm-¹, it decreased with increasing the concentration of nutrient Yield was higher at low concentration (4/1 dSㆍm-¹) at nighttime compared to the same concentration (4/4 dSㆍm-¹) at daytime and nighttime, and the reverse (1/4 dSㆍm-¹) was similar to the control (perlite culture).
