Techno-economic Evaluation of Naturally Ventilated Greenhouse for Capsicum Cultivation in Coastal Odisha

An experiment was conducted during October 2007 in a semi-cylindrical naturally ventilated greenhouse of 20 m x 5 m size for cultivation of capsicum at Bhubaneswar in coastal Odisha. The greenhouse was evaluated in terms of its techno-economic analysis, which was carried out by using different economic indicators such as net present worth (NPW), benefits-cost ratio (BCR), internal rate of return (IRR) and pay back period (PBP) and compared with open field cultivation. The net present worth of investment made on greenhouse for cultivation of capsicum was Rs. 1, 41, 633/- as compared to Rs. 22, 464/-when grown in open field. The benefit-cost ratio for greenhouse was 2.92 and 1.88 for open field cultivation. The internal rate of return for greenhouse cultivation was 47 per cent and 39 per cent for open field cultivation. The pay back period for capsicum under greenhouse was 5 years. It was observed that, techno-economically, cultivation of capsicum under naturally ventilated greenhouse will be viable and acceptable by the farmers of coastal Odisha.
