Abstract :

To achieve proper production in agricultural products, it is necessary to find suitable cultivation areas in terms of climate, geography and other parameters involved in growth and production. In this research, the possibility of cultivation and zoning of safflower susceptible areas in Dez basin has been investigated. For this purpose, water, soil, air and physiological information of the plant through library resources and opinions of experts of Khuzestan Agricultural Jihad Organization have been used for the study classification. Then, the effect of each factor on safflower yield was determined using AHP method. In order to locate and zoning the potential points of cultivation in the study area, the ordinary kriging model in GIS software environment was used. The results of data processing showed that 3% of the basin lands are in the appropriate range and 70% are in the medium range suitable for safflower cultivation.
