Abstract
An attempt was made to divide the Suru-Zanskar Valley of Ladakh division into agro-ecological zones in order to have an understanding of the cropping system that may be suitably adopted in such a high altitude region. For delineation of the Suru-Zanskar valley into agro-ecological zones bio-physical attributes of land such as elevation, climate, moisture adequacy index, soil texture, soil temperature, soil water holding capacity, slope, vegetation and agricultural productivity have been taken into consideration. The agricultural productivity of the valley has been worked out according to Bhatia’s (1967) productivity method and moisture adequacy index has been estimated on the basis of Subrmmanyam’s (1963) model. The land use zone map has been superimposed on moisture adequacy index, soil texture and soil temperature, soil water holding capacity, slope, vegetation and agricultural productivity zones to carve out different agro-ecological boundaries. The five agro-ecological zones were obtained. Key words: Agro-ecology, Suru-Zanskar, climatic water balance, moisture index.
