A field experiment was conducted to study the various climatological parameters taken under the environmental controlled and naturally ventilated polyhouse during March to July 2006. Both the polyhouses were planted with capsicum (Capsicum annuum L.). The climatic parameters such as temperature, relative humidity, and solar intensity were measured at 0900 hr, 1200 hr, and 1600 hr. The comparisons were also made with the ambient conditions prevailing in outside open field. The results reveal that the temperature was high at time 1200 hr followed by 1600 hr than 0900 hr. The temperature was observed higher in naturally ventilated polyhouse followed by the open field condition than environmental controlled polyhouse. Relative humidity was high in environmental controlled polyhouse followed by naturally ventilated polyhouse than open field condition; also, relative humidity was high at 0900 hr followed by 1600 hr than 1200 hr. The solar radiation was observed high in open field followed by environmental controlled polyhouse than naturally ventilated polyhouse, also observed high at 1200 hr followed by 1600 hr than 0900 hr.
