This study was conducted to investigate the influence of air temperature and relative humidity on excessive drying rate of burley tobacco. In experiment 1, 4 temperatures and 1 humidity by day and air curing by night were treated from initial curing stage. In experiment 2, 15 combinations of 3 temperatures and 5 humidities were applied from the yellow stage of cure. Yellowish cured leaves resulted from overdrying at high temperature and especially, at low humidity. However, these were not produced at 75-80 % RH and under 35 deg C by day with air curing by night. The proper range of temperature and humidity for desirable color of cured leaf were the combinations of 30 deg C, 75-80 % RH or 35 deg C, 80-85 % RH. As excessive drying leaves increased, physical properties of cured leaves were proper and chemical contents were less decomposed
