The wind is the most important climatic elements on corn yield. The Kermanshah province and Sarpolezahab County are major corn cultivation zones in Iran and province. The SAM wind is a limited factor on Autumn corn production. For doing this research, The climatic elements including daily Temperature, relative humidity and wind speed during 12 years ( 1374-1385 ) are taken from meteorological institute, Then The critical climatic Thresholds for corn were Analyzed. Because of coincide between these thresholds with SAM wind time, These thresholds were used as the beginning of SAM wind. The correlation among climatic elements with corn yield were achieved. The results indicate a significant correlation among climatic elements with corn yield. In this research, The best optimum planting date for corn is determined semi-ordibehesht( semi-may).
