干旱区生态环境知识资源中心

Ladakh, being cold, arid, high altitude region of India has a very harsh climate and a short agriculture season. Due to extreme long winter, the agriculture season is short, which extends from May-September in general, and in case of particular location, it depends upon altitude. Although the greenhouse technology is more than 200 years old but with the advent of plastics during the World War-II, a new phase in the greenhouse technology has emerged. The Defence Institute of High Altitude Research (DIHAR), one of the DRDO laboratories, is providing adequate support and technological help to set various types of green houses, both for the Army Units deployed in the far-flung areas and for the local farmers in the Ladakh. Till date, there were 65 greenhouses being established by DINAR in most of the Army Units deployed in the ’L’ sector with the average vegetable production of around 2000 kg/greenhouse/year. At present, the much needed vegetables are being grown throughout the year in these hostile climates under protective cultivation, which not only gives them the fresh food but also the nutritional security of the troops deployed.
