Eggplant (Solanum melongena L., cv. Senryounigou) plug transplants were grown for 17 days in a closed-type transplant production system at photosynthetic photon flux on the tray surface of 0, 100 and 350μmol m^<-2> s^<-1> on days 0-3, 4-6 and 7-16, respectively, air temperature of 30/20℃, (photoperiod/dark period) CO_2 concentration of 1000μmol mol^<-1> (photoperiod), relative humidity of 80/100% (photoperiod/dark period) and photoperiod of 16 h d^<-1>. The electric energy consumption per transplant was 0.35MJ (0.1kWh) and its cost was 1.4-1.5 Japanese Yen. The period required for transplant production was about 2 weeks shorter in the closed-type transplant production system than in the open-type transplant production system (i. e. the greenhouse). The amount of consumed water per tray area in the closed-type transplant production system would be reduced from 65.8 to 12.3 kg m^<-2> by reusing dehumidified water for irrigation. These results show that the closed-type transplant production system is feasible for commercialization.
