Abstract
Measurements of global, reflected and net radiation, soil surface and air temperature were made in three semi-cylindrical tunnel type greenhouses covered with transparent polyethylene sheets, cucumber (C. Sativa. Sandra) is used as green surface cover. The relative humidity inside the greenhouses in range of 35-45%, 65-75% and 90-100% respectively. The solar and thermal radiative environment inside the greenhouses were found to he strongly related to relative humidity. However, an increment in the relative humidity resulted in a significant reduction in global and reflected radiation. Also, it is observed that the maximum day-time and night-time net radiation is associated with high and low relative humidity respectively. High relative humidity caused marked increase in air temperature at day-time and sharp decrease at night-time.
