The present study was conducted with the aim of assessing the feasibility of changing the cultivation pattern from crops to the medicinal plant black seed in the villages of Borujen County. In the first stage, using the farmers' perspective and considering the agronomic criteria and compatibility with the conditions of the region, black seed was selected as the selected option for further investigation. This study was of a descriptive-survey type and data were collected from 145 farmer farmers using a researcher-made questionnaire based on Rogers's theory of diffusion of innovation. The reliability of the research tool was confirmed by calculating Cronbach's alpha coefficient (for all constructs higher than 0.7). For data analysis, one-sample t-test and Spearman's rank correlation coefficient were used in SPSS software. The results of the t-test showed that the observability construct was at the highest level with a mean of 3.42, and the adaptability and complexity constructs were also evaluated above the average, but the relative advantage did not differ significantly from the theoretical mean. Also, the results of Spearman's correlation showed that agricultural experience had a negative and significant relationship with testability. The findings indicate that the acceptance of black seed requires resolving economic ambiguities through guaranteed purchase contracts and strengthening observability by creating model farms, and the priority of extension programs should be focused on younger and educated groups.
