The biofertilizer potential of native bacteria isolated from the rhizospheric soil of eight plant species of economic importance from the Bagua and Utcubamba provinces, Amazonas region, Peru, was evaluated. The selection criteria were the solubilizing capacity of phosphates, the production of indole acetic acid and the asymbiotic fixation of atmospheric nitrogen, in addition to quantifying the diazotrophic bacteria present in each plant species studied. 57 plots located between 385 to 1677 m.a.s.l. were sampled, obtaining 235 isolates of native rhizoplane bacteria from cocoa, coffee, pineapple, banana, papaya, yucca, yacon and rice plants. The sampled soils were mainly loamy-sandy and loamy-loamy, with a variable pH between 3.30 and 8.09. Sixteen bacterial cultures of four plant species with biofertilizer potential were selected, finding that the rhizosphere of coffee crops has the highest amount of asbiotic nitrogen fixing bacteria, cocoa and yacon stand out for hosting excellent producers of indole acetic acid coffee and papaya crops, excellent phosphate solubilizers were isolated. In order to replace the use of chemical fertilizers, it is important to investigate the native rhizospheric populations of these four economically important Amazonian crops in search of native bacteria with biofertilizer potential to mitigate the consequences to the environment.
