Plant growth-promoting bacteria (PGPB) from drylands are promising biological resources to mitigate thenegative effects induced by water deficit. The aim of this study was evaluate the nativefrom Caatinga biome on initial growth melon plants subjected Nine (M1.1,T11.2, PH5.2, T11.1, T2.1, T1.1, M7.1, XX6.9 and XX6.6) isolated soils were tested in two varietiesof melons (Cantaloupe Yellow) cultivated under availability scenarios (50% irrigation 100%irrigation crop evapotranspiration - ETc). In control treatment, no inoculation performed. Theeffects treatments shoot length (SL), dry mass (SDM), root (RL) (RDM)were evaluated. scenario without deficit (100% ETc replacement), isolates T2.2, M7.1,XX6.9 promoted (p<0.05) biomasses Cantaloupe variety, while Yellow variety,growth promotion sporadic, with three (M1.1, M7.1 XX6.9) promoting at least one parameterevaluated. a T1.1 thetotal (SDM RDM) varieties, respectively. All stimulated RL inthe variety. Bacteria promote reduce waterdeficit thus potential inoculants enhance production early stages cultivationin semiarid regions.
