Abstract:

Ensuring food security and agricultural livelihood requires a comprehensive and systematic approach with the aim of sustainable use and management of natural resources through the development and adaptation of agricultural technology. Sesame is one of the most important oil seeds. Due to its strategic importance, determining suitable areas by considering climatic and soil parameters is considered one of the best solutions in sustainable production. Therefore, the aim of this study is to zonate the agricultural ecological potential of 6 cities (Hirmand, Zabul, Zahedan, Zahk, Hamon and Nimroz) in the north and center of Sistan and Baluchestan province for sesame cultivation using climatic and soil parameters. In this study, for the zoning of sesame cultivation, a total of 16 spatial criteria (optimal temperature, temperature set, minimum temperature, maximum temperature, precipitation, slope, elevation, organic matter, soil salinity, pH and amount of nutrients It contains nitrogen, phosphorus, potassium, iron and zinc in the soil. Analytical Hierarchy Process (AHP) method, Boolean logic to classify criteria into suitable and unsuitable classes, and Weighted Linear Combination (WLC) method to obtain a zoning map have been used to obtain the weights of the criteria. . The results showed that among the selected criteria for preparing the sesame cultivation map, average rainfall and minimum temperature have the highest and lowest weight, respectively. The results of the final suitability map for sesame cultivation in the studied area showed that the highest percentage of the area belongs to the very unsuitable class (0.616) and the lowest percentage belongs to the very suitable class (0.016). Also, the results of the area percentage of different classes separately for each city for sesame cultivation showed that among the studied cities, Zahedan city has more area in the very suitable class than other cities. The functional results of sesame in the studied areas were consistent with the results of the research.
