Abstract

In this study, with goal the estimation of yield production potential in 30 provinces center in Iran, firstly using factor and cluster analysis and with nine climate factors, the stations were classified. According to the percentage of variance and special values of effective factors, KMO value was equal to 0.598 that four climatic parameters including mean temperature, relative humidity, wind speed and precipitation were selected in grouping process. As a result, regionalism method based cropped ecology in arid low precipitation regions of the country could not estimate potential production of wheat yield. In region with semi-arid- semi humid climate, the lowest and highest yield vacuity percent with 30.9 and 53.5 is in the Ardebil and Ilam stations, respectively. Also results showed that model from between the climatic factors, has the greatest sensitivity to average temperature. This has caused that the lowest yield vacuum be in regions with low precipitation and dry climates with 15 and 27.5 percent, respectively. Conciliation of results represented that regionalism method based cropped ecology is one of the appropriate method for predicting wheat yield and determining yield vacuity in different climatic regions
