A field experiment was carried out as factorial based on randomized complete blocks design (RCBD) with 10 treatments and three replications at the Faculty of Agriculture, University of Maragheh during 2021 growing season. The first factor was consisted of different planting patterns including monoculture of chickpea, monoculture of black cumin, 1 row intercropping of chickpea + 1 black cumin (1:1), 1 row chickpea+ 2 row black cumin (1:2) and 2 row chickpea+ 1 row black cumin (2:1) and the second factor was inoculation and non-inoculation with mychorrizal fungus. The results demonstrated that the seed yield of black cumin was significantly affected by different planting patterns and mychorrizal fungus. The highest seed yield of black cumin (823.3 kg ha-1) was achieved in its monoculture. Application of mychorrizal fungus increased the seed yield of black cumin by 18.59% in compared with non-application. In addition, the highest essential oil percentage (1.06) and essential oil yield (7.326 g.m-2) were achieved in the 1 row chickpea+ 2 row black cumin intercropping pattern. Generally, the planting pattern of 1 row chickpea+ 2 row black cumin (1:2) with application of mychorrizal fungus not only leading to agricultural ecosystems diversity and sustainable productivity, but also effective in enhancing economic income and land use efficiency.
