Experiments were conducted during winter 2002–03 and 2003–04 in a semi-cylindrical greenhouse and greenhouse with shadenet of 4m x 12m sizes each for cultivation of okra at Bhubaneswar in coastal Orissa. The greenhouse and greenhouse with shadenet were evaluated in terms of their techno-economic analysis, which was carried out by using different economic indicators such as Net Present Worth (NPW), Benefit-cost ratio (BCR), Internal Rate of Return (IRR) and Pay Back Period (PBP) and compared with open field cultivation. The worth of investment made on greenhouse and greenhouse with shadenet for cultivation of okra were Rs.3,256.00 and Rs. 5,384.00 respectively as compared to Rs. 431.00 when grown in the open field. The benefit-cost ratio for greenhouse and greenhouse with shadenet were 1.15 and 1.24, respectively and 1.06 for open field cultivation. The internal rate of return for greenhouse and greenhouse with shade net were 14 and 15 per cent, respectively and 11 per cent for open field cultivation. The pay back period for okra under greenhouse and greenhouse with shadenet were 15 and 14 years, respectively. It was observed that, techno-economically; cultivation of okra in winter under greenhouse and greenhouse with shadenet will be acceptable by the farmers of Orissa.
