Abstract
This research was conducted to investigate difference of internal temperature, humidity, and plant growth according to covering materials in sweet pepper's greenhouse. For growing period, daily mean internal temperature was not different between glass (GH) and plastic film house (PH), but the changed volume was more PH than GH. Internal humidity deficit was more PH than GH as that was 4.3 $g{\cdot}m^{-2}$ and 5.6 $g{\cdot}m^{-2}$, respectively. In change of internal temperature effected by different intensity of external light, that of PH was fasted twice that of GH, and that's tendency was effected by difference of internal temperature for several hours after sunrise. Leaf growth and photosynthetic product were more GH than PH, productivity of GH was better 80 percents than PH. As results, To improve productivity in PH compared with productivity in GH need to be the detailed managements of internal environmental factors in early period after sunrise.
