This experiment was carried out using a split factorial based randomized complete block design with 4 replications. The factors studied included two levels of drought stress, application and non-application of mycorrhiza ( Glomus hoi) and 0, 35 and 70 kg ha-1 phosphorus applications. The results showed that drought stress had significant effect on essential oil yield, biological yield, shoot P content, root yield, seed yield and harvest index and the highest upon plant characteristics were achieved under without drought stress condition. Also, mycorrhiza and phosphorus application had significant effects on essential oil yield, biological yield, shoot P content, root yield and seed yield. Highest of this characteristics were achieved under application of mycorrhiza and 70 kg ha-1 phosphorus.The findings indicated that AMF inoculation of coriander contributes to improved water and phosphorous uptake for the production of below-ground organs and helps maintain accumulation of dry matter.
