Tomatoes were experimented in perlite bags for various irrigation control methods to elucidate the efficient method for nutrient solution management. The irrigation control methods were for 3 different types such as control by drainage level sensor (PROBE), control by integrated solar radiation (ISR), and control by time clock (Timer). The substrate weight was maintained stably in the proper range in PROBE treatment, regardless of daily solar radiations or growth stages. The bed weights in the treatments of ISR and Timer were changed largely. Growth as well as total yield was the highest in PROBE treatment.
