Vapour pressure deficit (VPD) is considered as an important environmental factor that affect transpiration rate (TR) in plants. In this study, transpiration rate were observed in Pepper (Capsicum capsaularis) in 3 different soil conditions (organic, sand and mineral) subjected to low (0.10-1.5) and high VPD (2.50-3.90). The highest transpiration rate noted in mineral soil (2.08) but organic one showed more exponential results under high VPD (3.29), comparing lower leaf area to other soil conditions. The lowest TR indicated in sands (0.17) with lower VPD level and large leaf area. The results showed that sand has the lowest transpiration rate and organic soil has the highest transpiration rate. Adding more substrate will be better to compare the transpiration
