A field experiment was conducted at to study the effect of cyclic and fertigation on off-season production of capsicum (Capsicum annuum L.) under protected environment. The treatment consists of two irrigation levels (100 and 75 % of water requirement) and three cycles' level (One cycle per day, three cycles per day and six cycles per day) and two level of Fertigation in naturally ventilated polyhouse (NVPH) (normal and split fertigation) and only split Fertigation in environmentally controlled polyhouse (ECPH). The results revealed that the plant height was higher in NVPH where as the number of primary and secondary branches, canopy perimeter, yield, and yield attributes were higher in ECPH than NVPH. The irrigation treatment with three cycles per day under split fertigation (10.97, 10.10) has higher yield than six cycles (10.57, 9.33) and one cycle (7.59, 9.33) under split fertigation in ECPH and NVPH respectively. The water use efficiency was higher under treatment of three cycles per day with combination of 75 per cent of water requirement under split Fertigation in both polyhouse. The cyclic irrigation increased the water-use efficiency.
