The research was carried out at Kuskeis Research Station during the agricultural season 2019/2020, to show the effect of isolates of mycorrhizae on the growth of the black barley crop under rain-fed conditions. turf, onion, corn) and my mycorrhizal concentration was (2.5 ml, 5 ml) in addition to the control, By studying the growth indicators, it was found that the treatment (bm22) mycorrhizae type II, the second concentration, was superior among the treatments with respect to plant height, and the treatment (bm32) mycorrhizal type III, the second concentration, with respect to root length and spike length, and the results showed for plant weight and root weight the superiority of treatment (bm22). Mycorrhiza type II concentration II plant weight, And the treatment (bm12) mycorrhiza the first type, the second concentration for the weight of the root, and the superiority of the treatments of (bm22) the second type, the second concentration, in the weight of a thousand grains, the number of spikes in m2 and grain yield, as well as in the availability of phosphorous in the soil, As for potassium in soil, the treatment (bm32) of the third type outperformed the second concentration in its availability, and the superiority of treatment (bm22) in the rate of mycorrhizal infection in all stages of plant growth, this treatment was the best in the rate of infection and response to the vaccine and the reflection of that On the availability of phosphorous and plant growth by improving its productivity in rain-fed conditions

Key words: drought, barley, mycorrhiza, (Arbuscular Mycorrhiza fungi) AMF
