Relative humidity (RH) has a direct impact on plant water relations and has an indirect impact on leaf growth, photosynthesis, pollination, disease occurrence, and, ultimately, economic production. Because there is less transpiration when the humidity is low, the turgor pressure is high. As a result, leaf elongation is common in humid environments. RH has an indirect effect on photosynthesis. When the relative humidity (RH) is low, transpiration rises, resulting in water deficiencies in the plant. Many crops benefit from moderately low air humidity, as long as the soil moisture supply is adequate. Insect pests and diseases are more common in high-humidity environments.
