摘要

This study aimed to investigate the effects of different combinations of arbuscular mycorrhizal fungi (AMF) species and irrigation strategies on the growth, yield, and irrigation water use efficiency (IWUE) of black cumin (Nigella sativa). A greenhouse experiment utilized sterilized soil in pots with black cumin seeds treated (cv. Çameli) with various AMF species. The design included four AMF treatments (Control, Glomus spp. (Shubhodaya),  G. iranicum, and G. fasciculatum) and four irrigation levels (100%, 75%, 50%, and 25% of field capacity) in a randomized design with three replicates each. Results indicated that AMF inoculation significantly improved yield and IWUE compared to the control. The highest yield was observed with G. fasciculatum under optimal irrigation, yielding 0.63 g per pot, while the highest IWUE was recorded with G. fasciculatum (M3) at 0.124 g L− 1 under optimal irrigation. Reduced irrigation levels negatively impacted all growth parameters that were mitigated by AMF inoculation. Integrating AMF inoculation, especially with G. fasciculatum, and effective irrigation strategies significantly enhances the growth, yield, and IWUE of black cumin.
