The objective of this study is to assess a GIS-based model for barley production potential in Damghan plain of Iran. The assessment of Land Production Potential for barley, Using Geographic Information System method was used on the crop requirements, climatic and soil properties which will allow the prediction of crop yield. Integrating a crop growth model with GIS allowed studying the variability of barley production potential in different conditions at a regional scale. Regarding to FAO model, the estimated LPP values for the studied area varied between 353 to 5278 kg.ha-1 respectively. This study shows that the average farmers' yield was higher than the calculated LPP values by GIS method. The computed values of net biomass production and yield showed that the barley production potential was almost suitable in Damghan plain. One notable limitation for this method is that it requires an accurate assessment of effective parameters on crop yield.
