An approach to agricultural management is to select and to identify susceptible regions for sowing according to the climatologic and physiographic condition of the land. Knowing this enables the farmers to farm in line with the physical and climatologic conditions of the land and to decrease the crop injuries due to the undesirable climatologic conditions. There fore, this approach can be an effective method to develop and to optimize agricultural activities. Thus in this study, with the objective of determining the propitious areas to plant potato in Kermanshah province, we tried to present the numerical map of the land physical factors (height, slope, soil depth) and climatologic elements(temperature, pre capitation, relative humidity, evaporation and day degree) using Geographical Information System (GIS) and to dedicate values to the layers with respect to the potato cultivating need. And in final with incorporation of all data, supplied final map potato plant. The result confirmed near 3/7 percent areas of Kermanshah is very suitable, 16/1 percent suitable, 32/7 percent medium and near 47/4 percent is unsuitable for potato cultivating.
