Abstract

Saffron (Crocus sativus L.) is a valuable crop and medicinal plant, including with respect to withstand drought significant role in Iran's non-oil exports. Climate is one of the most important in environmental variables. In addition, accurate knowledge of the agricultural products characteristics in every area is the basis of agricultural development. Identification of potential areas for cultivation sets the stage for essential planning for expansion of this crop is essential operation. In this study tried to zone potential areas for saffron crop in Semnan city by assessing climatic conditions so, four weather stations were selected in a statistical 10- year period (during 2004-2014). Modeling and data analysis were performed by using Arc GIS software. According to climatic conditions, suitable for each stage of saffron growth cycle, information layers were classified and weighted. Analytical Hierarchy Process (AHP) and Analytic Network Process (ANP) were used for integrating information layers. Finally, climatic zoning map of cultivation saffron in Semnan city was drawn. At this study, AHP and ANP techniques were compared. AHP results showed about 59.5, 34.5 and 6 percent of the city were best, average and weak for saffron cultivation, respectively. But in ANP method 32, 48 and 20 percent of the city were best, average and weak for the crop cultivation, respectively.
