Abstract:A GIS has been used to match the suitability for barley crop based on the requirements of the crop and the quality and characteristics of land. The methodology used for the physical land suitability analysis for barley is a multi-criteria evaluation approach within GIS context. This study, land suitability evaluation based on FAO has been determined for barley irrigated area about 5400 ha the south of plains Damghan. The study was carried out by overlapping all individual maps (soil map units, soil depth map, slope map, texture soil map, and soil fertility) with GIS techniques for physical land suitability classification. The results show that 15.88% of the area is S2 (moderately suitable) and 26.55% S3 (marginally suitable) and 57.57% and N2 (permanently unsuitable) for barley crop. Lack of irrigation suitable water, soil salinity, insufficient rainfall and poor soil fertility are the most serious problems influencing yield and quality of barley.
