The effect of multi-PGP trait root-bacterial endophytes on root growth of sorghum (genotype R-16) seedlings under drought stress condition (a). Effect of multi-trait PGP rhizobacterial endophytes on root surface area (b) and free proline accumulation in leaves (c) relative water content or RWC (d) and membrane stability index or MSI (e) of the sorghum grown in soilrite mix under watered and drought stress conditions. Based on Duncan’s multiple-range test (DMRT), the bars in graph with the same alphabet letter indicate non-significance at P ≥ 0.05
