The effects of arbuscular mycorrhizae on water use efficiency and some growth characteristics of maize were studied at three water regimes. An farm experiment was carried out using a split plot based randomized complete block design with 3 replications. Main plot was under water deficit condition (100%FC, 66%FC, 33%FC) and sub plot included application of two species of mycorrhizae, M1:Glomus mosseae , M2:Glomus intraradices and M0: no application of mycorrhizae. The results showed that the interaction effects of water deficit condition and application of mycorrhizae on water use efficiency, root colonization percentage, harvest index, LAI, CGR, statistically was significant. The highest of water use efficiency was detected under water deficit condition (33%FC) and Glomus mosseae and the least allocated to non application of mycorrhizae under without water deficit condition (2.34 Kg/m3, 1.23 Kg/m3, respectively). The results revealed a high correlation among root colonization percentage and water use efficiency under water deficit condition (33%FC) and application of mycorrhizae.
