Sustainable Seedlings Raising and Vegetable Cultivation in a Greenhouse Integrated with Solar Photovoltaic and Earth Air Heat Exchanger System
The suitability of a low-tech naturally ventilated greenhouse integrated with earth air heat exchanger (EAHE) and solar photovoltaic (SPV) module was evaluated for off-season and on-season cultivation of capsicum (variety California Wonder) in warm and humid climate i.e., in coastal Odisha, Bhubaneswar, Odisha, India because of its high demand throughout the year. The cultivation of this vegetable was tried in two seasons, one from September to December (on-season) and the second one from January to April (off-season) during the year 2010–11 and nursery raising of high valued seedlings i.e., acacia mangium was done two times during rest of the period for year round use of the experimental greenhouse. The benefit cost ratio for capsicum cultivation in the greenhouse was 7:1 whereas it was 1.84:1 in case of open field condition. The payback period of the system was estimated to be only 2.20 years.
