Banana crops require higher amounts of chemical fertilizers to meet the demand of productivity international markets, which represent high costs and can be hazardous to the environment. Plant growth-promoting rhizobacteria can improve the nutrients use efficiency through their bio-chemical abilities, eventually, partially replace chemical fertilizers without reducing productiv-ity. So, this study was aimed to evaluate the agronomic efficiency of several bacterial strains, in combination with levels of N fertilization, on morphophysiological, biochemical, and nutritional characteristics related to the growth of banana seedlings, Prata Ana cultivar. The experiment was conducted in greenhouse in a 6 x 5 factorial scheme with the following factors: (1) inoculation with BR11005, BR11674, BR12137, BR12157 or BR12158, and a treatment without inoculation; and (2) doses of N (0, 50, 100, 150 or 200 mg kg-1 of substrate). Bacterial strains were character-ized with respect to genetical, biochemical and physiological aspects. Ninety days after trans-planting, plant height, pseudostem diameter, number of leaves, total leaf area, root volume, total dry mass, total content of chlorophyll, carotenoids, and proline contents, N concentrations and their use efficiency were evaluated. Only strains BR11005 (Azospirillum baldaniorum) and BR12157 (Bacillus velezensis) showed potential to improve the performance of growth-related morphophysiological traits and N use eficiency. The strains are effective for biological N fixation, potassium, and phosphate solubilization, auxin synthesis, and production of siderophores, and hydrolytic enzymes. The performance of plants treated with these strains exceeded those of fertil-ization with 200 mg kg-1 of N treatment.
