In order to study the ecological relationships between Solanum elaeagnifolium Cav. and the main biotic and abiotic factors in the irrigated arid Tadla plain (central Morocco), the theory of mutual information and corrected frequency profiles has been adopted. The main ecological factors taken into account in this study were the climate, soil, texture, salinity, irrigation, type of land use and the intensity of farming. The growth and extension of S. elaeagnifolium was found to be controlled by the arid and semi‐arid Mediterranean climate, by soil type and by technical and agronomic factors.
