Conteúdo: 	The study was conducted to evaluate the potential of a mixture of five diazotrophic bacteria applied as an inoculant to mitigate the negative effects of the water deficit on the physiological and on the biometrics aspects of the growth of five varieties of sugarcane subjected to water stress. The RB867515, RB966928, RB106814, RB106818, and RB106819 varieties were used for study. These were treated with and without the use of a mixture of five strains of diazotrophic bacteria, under adequate irrigation conditions and under total water restriction. Each plot was represented by a sugarcane plant, in four replicates; via a randomized blocks design, in a split plot scheme. Compared to the uninoculated control, inoculation resulted in an increase in net carbon assimilation (15%), chlorophyll content (30%), and osmotic potential (28%) in the plants, besides of a dry mass yield increase. In addition, inoculated plants were able to maintain higher stomatal conductance and relative water content in the leaf, whereas decreasing 6% leaf transpiration rate of plants. The presence of these bacteria mixture improves the morpho-physiological characteristics, helping to mitigate the effects of water deficit in sugarcane plants, regardless of the used sugarcane varieties. Results also highlight that the plant restored an adequate growth performance by maintaining its gas exchange parameters integrity.
