چکیده :

In order to investigate the effect of biostimulants on agronomic traits of cumin under different irrigation conditions, a two-factor experiment was conducted in a randomized complete block design in the greenhouse of Imam Khomeini International University. Experimental factors included 1- Irrigation at two levels of 100% field capacity and 50% field capacity; 2. Biostimulants at four levels included non-application of biostimulants (control), application of mycorrhizal fungi, application of seaweed, combined application of mycorrhizal fungi and seaweed. The studied traits included grain yield, yield components and essential oil percentage. The results of analysis of variance showed that the effect of irrigation and biostimulants on all studied traits was significant. The interaction effect of irrigation × biostimulant was significant for most traits except height, number of seeds per umbel, 1000-seed weight and essential oil. The highest amount of traits was observed in the treatment of simultaneous application of seaweed and mycorrhizal fungi in conditions of 100% of field capacity and the lowest amount of traits in conditions of irrigation with 50% of field capacity and no application of biostimulant. Application of mycorrhizal fungi and seaweed alone and in combination reduced the adverse effects of drought stress, but the greatest effect of these biostimulants was observed in their combined application.
