Development of Low-cost Detachable Roof Greenhouse for Round the Year Cultivation of Tomato and Capsicum

Abstract

Greenhouse is a well-established technology for crop cultivation or nursery growing under controlled, or partially controlled, condition. The major hindrance in its widespread adoption is construction cost and environment management. A low-cost detachable roof greenhouse was developed for round-the-year cultivation of tomato/capsicum. The temperature under the greenhouse during winter season (November-February) was 1-3 0C higher than at open field condition due to greenhouse effect. The temperature during summer season (March-June) in the greenhouse was between 5-46 0C, and was lower than the temperature (6-49 0C) under open field condition. During rainy season (July-October), the temperature recorded were 9-38 0C and 12-41 0C, respectively, under greenhouse and open field condition. The light intensity and relative humidity in the greenhouse varied between 0.7-53.2 klux and 14-96 %, respectively.
