Abstract
In order to investigate the effect of mycorrhizal fungus on the characteristics of herbaceous plant under stress
conditions, a factorial experiment was carried out in a randomized complete block design with three
replications at the Agricultural Research Farm of Urmia University in 2012-2013. Irrigation at three levels;
irrigation after 50 (control), 100 (medium stress) and 150 mm evaporation from class A evaporation pan
(severe stress) as the first factor and association of fungi (control and glomus intraradices) as a second factor
was considered. The results showed that with increasing irrigation levels from 50 to 150 mm (evaporation from
pan), seed number per pod, 1000 seed weight and essential oil yield of Fenugreek decreased significantly. The
highest percentage of essential oil was obtained from 100 mm irrigation water evaporation from the pan. Also,
at each level of irrigation (50, 100, 150 mm evaporation), the maximum total chlorophyll content, relative
water content of leaves, biological yield and grain yield of Fenugreek were obtained was obtained from
treatment of mycorrhizal fungi.
