Abstract

The limited resources in Iran's agricultural sector (especially the lack of land and water) make it necessary to prioritize the production of products in different regions. On the other hand, Iran has suitable capacities for the production of medicinal plants, but this capacity is not the same in different provinces of the country, and it is necessary to identify the appropriate provinces for the cultivation of these products for each medicinal plant. Therefore, the main goal of this research is to prioritize the appropriate provinces for the cultivation of Nigella Sativa production (as a high-consumption medicinal plants) using relative advantage index. The reason for choosing Nigella Sativa is that so far, there has been rarely a study on the comparative advantage of these products. In this research, in order to measure the regional relative advantage of Iran's provinces, spatial coefficient (LQ) and symmetrical spatial coefficient (SLQ) indexes have been calculated with the data of year 2022 and for three different production baskets. The results showed that the provinces of Golestan, Chaharmahal and Bakhtiari, Fars and Lorestan in the production of nigella sativa.
