Brief Description (Abstract):

The optimization of greenhouse climate at Maitri station in Antarctica is described. Strategies for controlling temperature, humidity, light and CO2 concentration are described. Heating load has been estimated. July was the coldest month and required most heating. Annual heating degree days at 25? C indoor temperature were 13277.3, while those for 20? C and 15? C indoor temperatures were 11452.3 and 9627.3 respectively. Annual heating loads at 25, 20 and 15? C indoor temperatures were 77038.56, 66449.04 and 55859.28 MJ respectively. Monthly heating loads varied between 4424.88 and 8993.52 MJ at 25? C indoor temperature. Annual heating loads varied in accordance with the greenhouse temperature as Hmj = 24166.57 +2114.04 *Tg Maximum PAR (Photosynthetically Active Radiation) level at the ice surface reaches upto 90000 lux. PAR levels inside the greenhouse varied between 100 and 45000 lux during polar day.

Status: Completed

Purpose: Antarctica, the most isolated continent, has only 2 of its area as free of ice. Apart from snow algae, lower species of plant kingdom viz. moss and lichens are found in these zones. Antarctic water and soil have a little amount of nutrients, so the growth of these species is poor. The severe Antarctic climate limits the number of land plants that are able to grow. Higher plants can not survive here because of extremely low temperatures although two vascular plants Colobanthus quitensis and Deschampsia antarctica have been reported to grow in Antarctic peninsula. In order to grow plants in Antarctica, protected cultivation is the only way as outlined by Joshi and Banerjee (1988) and Kononov and Kiran (1988). Intensive production of vegetables is possible in greenhouses under controlled environment. In order to study plant growth and yield of vegetable crops, a greenhouse was constructed at Maitri station during the IX Antarctic Expedition.
