Locating suitable places for sunflower cultivation using GIS (Case study of Dez Basin)

Cultivation of agricultural products faces various constraints such as climatic constraints. In any climatic and geographical conditions for the cultivation of different crops requires a preliminary study of suitable cultivation conditions and location. The main purpose of this study is to identify areas prone to sunflower cultivation in the Dez Basin. For this purpose, after determining the study area, the effective factors in plant cultivation were determined using library resources and the opinions of experts. Then the effect of each factor on the yield of sunflower plant was determined using AHP method. In order to locate and zoning the potential points of cultivation in the study area, a ordinary kriging model was used in the ARC GIS software environment. The results of data processing showed that 29.5% of the basin lands are in a very suitable range, 69% in a suitable range and 1.5% in a suitable medium range for sunflower cultivation.
