A field experiment was conducted at experimental field of Department of Irrigation and Drainage Engineering to study the response of cyclic irrigation on biometric and yield parameter of capsicum (Capsicum annum L.) in environmental controlled and naturally ventilated polyhouse. The treatment consists of two irrigation levels (100 % of water requirement and 75 % of water requirement) and three cycles' level (One cycle per day, three cycles per day and six cycles per day). The results revealed that the plant height, number of primary branches, number of secondary branches and canopy perimeter was higher in environmental controlled polyhouse than naturally ventilated polyhouse, also the yield and yield attributes was higher in environmental controlled polyhouse than naturally ventilated polyhouse. The irrigation treatment with three cycles per day performed better than six cycles and one cycle in both the polyhouses. The water use efficiency was high in treatment of three cycles per day with combination of 75 per cent of water requirement in both polyhouse. The cyclic irrigation increased the water-use efficiency.
