Abstract: 
Evidence indicated that climate change in arid and semi-arid areas through reduction of rainfall and an increase in temperature and also potential evapotranspiration, reduces growth and hence yield of wheat. The aim of the present investigation was to evaluate the effects of temperature and rainfall changes on growth rate and yield of rainfed wheat (Sardari cultivar) under future climatic condition of Iran. For this purpose WOFOST model for the the present climatic conditions and the years 2025 and 2050, on the basis of UKMO General Circulation Model was used and changes on growth and yield were compared. Results of growth simulation showed that growth rate of rainfed wheat will be reduced by 20-30% for the years 2025 and 2050, respectively. Furthermore despite and increase in CO2 concentration, yield of wheat will not increase in the eastern parts of the country compared to the Western parts. Average reduction in yield will be 20.6% for the year 2025 and 28.8% for the year 2050.
