Ilex paraguariensis plantations cover more than 160.000 ha in Misiones. Actually, plantations have  good  production,  but  more  degraded  plantations  are  arising  caused  by  monoculture  and inadequate soil management practices. Plant growth promoting bacteria (PGPB) isolated from I. paraguariensis roots and rhizosphere are a promising alternative to mitigate that problem. We inoculated 6 and 50-year-old plantations with native PGPB strains and evaluated changes due to inoculation  in  solar  radiation  interception  and  chlorophylls  concentrations.  Solar  radiation interception was  greater  in inoculated plants in 6-yeard-old plantations while no changes were observer in 50-year-old one. No changes were observer in chlorophylls concentrations.
