Abstract :

The Date is dryness is a majer Problem in South ern Portsofiran. Despite lots of damages tothis region economy,The main purposes of this study the effect of,UV, Ozon (O3) andclimatological factors including temperature and relative humidity on date dryness. The studywas done based on two models, Artificial Neurol networks well as regression model grade 3which was made by the main component. Therefore, the two models results were analyzedand compared with each other while the determination index for former model was R2 = 0.999and for the later one it was R2 = 0.92. However, it was revealed that the results of artificialNeurol networks were more exact. Consequently, it concluded that based on this study resultsthere was a direct, positive relationship between the origin of the bunch of Mozafati drynessdifficulty and the temperature, radiation and Ozon while it showed opposite relation withrelativehumidity.
