Abstract

The purpose of this paper is to examine the conditions of Agro climatic of wheat in Kermanshah province by using GIS in selected stations. In this study, data from meteorological stations in Kermanshah province on a daily basis and monthly and yearly Meteorological Organization’s have been investigated. The research method is descriptive statistics. Data analysis using gradients, deviation from optimal conditions, phenology index (GDD), EXCEL and SPSS statistical software in the environment of the potential heat is done and then the amount of annual rainfall, winter and spring are calculated for all stations. The calendar for wheat planting conditions in terms of temperature for all stations is October to mid-November. Wheat harvest Kermanshah station, Kangavar, Islamabad and Rawansar the early and mid of May to mid-August in Sarpolzohab station. According to the phenology of planting to germination, elongation, and reaching to plant wheat dough, respectively Sarpolzohab station starts earlier than other stations. The results show that moving from east to west province, favourable areas of wheat cultivation are observed. This process is similar to the distribution of annual rainfall in the province. Also, the adaptation layers in the process of dryland wheat in GIS, are able to identify the utility of this valuable plant for planting.
