ABSTRACT    Drought stress conditions adversely affect the crop production, but fortunately mycorrhiza help the crops in coping with the conditions, and the impact should be determined. For the same purpose two wheat varieties were introduced to the arbuscular mycorrhizal (AM) fungus and the impacts were calculated in the form of grain production, and mineral acquisition. (Triticum aestivum L.) Cultivars that have been cultivated in the field in both well-watered and water-stressed environments. Results showed that, mycorrhizal plants had better biomass and grain yields than non-mycorrhizal plants. in comparison moderate or severe water stress treatments, mycorrhizal plants had considerably greater total dry weight and leaf chlorophyll concentrations than non-mycorrhizal plants. Throughout the experiment, plants were treated to low-level water stress and severe water stress (Mild (50%) and severe (30%) water deficit regimes). The effect of water levels on wheat Growth parameters (vegetative stage), as in control the mean value of number of leaves (6.4±1.527), plant height (23±2.6) and root length (2.67±0.57) while compared with the treated crop (Triticum aestivum L.) Number of leaves (4.33±0.577), plant height (15±1) and root length (1.66±0.577) there were clear difference that Arbuscular mycorrhizal inoculated plants were more pronounced effect than the other treatments and control. By comparison the plants having Mycorrhizal association vegetative stage the means of plant height (23.33±1.154), No of leaves (9.33±1.527), root length (4±0) was higher than non- treated plants havin plant height (20±1), No of leaves (7.66±1.15), and root length were (3.33±1.154). the identified fungal species were (Glomus spp. Acaulospora spp. Sclerocystisspp)) and root colonization were also observed root colonization was high in inoculated plants than non-inoculated plants. © 2022 Department of Agricultural Sciences, AIOU
