O cultivo de minirosas tem grande relevância ornamental e econômica. A fim de atender à demanda comercial por produtos de alta qualidade, é necessário o uso de tecnologias que assegurem a competitividade do produtor. A inoculação de microrganismos promotores de crescimento se apresenta como uma estratégia sustentável, que favorece o crescimento saudável das plantas, aumenta o vigor das mudas e contribui para práticas de manejo mais eficientes. O objetivo deste trabalho foi avaliar o efeito de rizobactérias sobre o crescimento e desenvolvimento de minirosas ‘Two Tone Jewel’. O experimento foi conduzido em delineamento inteiramente casualizado com seis tratamentos correspondentes aos microrganismos Azospirillum brasilense, Bacillus amyloliquefaciens, Bacillus megaterium, Bacillus pumilus, Bacillus subtilis e o controle, sem inoculação, com 4 repetições. Os parâmetros avaliados incluíram número de folhas, área foliar, altura da parte áerea, número de botões e flores abertas, massa seca da parte aérea, massa seca de raízes e massa seca total. A. brasilense apresentou os valores mais elevados na maioria dos parâmetros, juntamente com B. amyloliquefaciens que se distinguiu em área foliar e massa seca da parte aérea. A inoculação com Azospirillum brasilense e Bacillus amyloliquefaciens pode apresentar potencial para integração em estratégias sustentáveis de produção de minirosas; entretanto, não foram observados efeitos estatisticamente significativos sobre o crescimento e o florescimento nas condições avaliadas.
