Simulation yield of maize based on scenarios of climate change in Fars province

Simulation yield of maize based on scenarios of climate change in Fars province .Maize is a very important and fruitful production that is effect by the climate in its yield the purpose of thesis research is the simulation of the maize function to scenario of climate change to the present and future. So to survey the region climate, daily data, maximum and minimum temperature, precipitation and radiation have been utilized during the period of (1987-2016).
In order to simulating of climate in future, firstly the date of IPCM4 model under scenario and 30’s and 50’s with downscaling LARS-WG model. Before the simulation yield of maize, APSIM model was evaluated and validated. To calculated the maize yield the out put of LARS model ,plant date and … were utilized as the cropping input model of APSIM. By variance analysis maize yield was compared in present and future. The results showed that the APSIM model validation can simulate acceptable accuracy and climate parameters change affect on the yield rate of maize.
