Objective: To evaluate the application of microorganisms with native strains on the growth of Morus alba Linn under semi-controlled conditions. Materials and Methods: The work was carried out at the Mountain Development Center, El Salvador municipality, Guantánamo province. Stakes of M. alba, 30 cm long with five buds, were used. Fersialytic soil and organic matter (sheep manure) were used as substrate in a 3:1 ratio. Four concentrations of the microorganism with native strains were applied: 5, 10, 15 and 20 mL/L, which constituted the treatments. A control was used, with water only. A complete randomized experimental design was applied, with 20 plants per treatment. Measurements were branch number, root number, leaf number, branch length, stem diameter and root length. The data were processed from a simple classification analysis of variance. Results: There were no significant differences for the number of branches and number of leaves. Regarding the number of roots, the best treatment was T2, which differed significantly from the others. Treatments T2 and T3 tended to have the highest numerical values. As for branch length and root length, there were significant differences among treatments. No differences were found in stem diameter. The highest numerical values in all indicators were obtained with the application of 5 and 10 mL/L of the bioproduct on M. alba seedlings. Conclusions: With the application of 5 and 10 mL/L of microorganisms with native strains, the performance of branch length, number of roots and root length of M. alba seedlings was favored.
