A field experiment was carried on, with five treatments and five replicates, evaluating the growth and yield responses of inoculated carrots. Responses were observed in height only two weeks before harvesting, and the number of leaves was most affected from the beginning to the middle of the cultivation cycle. Although the fresh shoot mass was negatively affected by the inoculation treatments, the dry shoot mass did not respond to the rhizobacteria. The length of roots inoculated with <em>P.</em> <em>fluorescens</em> or co-inoculated with both bacteria increased from 21 cm, without inoculation, to 25 cm. The root volume and dry mass values were the same across the treatments. However, the fresh root mass was improved by between 70 and 81.8% with <em>P. fluorescens</em> and co-inoculation, respectively. More positive responses to inoculation were observed with reduced nitrogen levels, suggesting a potential in the rhizobacteria strains for use in reduced-input agricultural practices. Moreover, based on the findings, <em>Pseudomonas fluorescens</em> can be recommended as a plant growth-promoting microorganism in carrot cultivation.</p>}, number={3}, journal={Revista Colombiana de Ciencias Hortícolas}, author={França, Ana Rosa da Silva and Borcioni, Elis and Paixão, Crysttian Arantes and Araújo, Ricardo Silva and Campos, Rangel Viganó de and Cruz, Sonia Purin da}, year={2020}, month={Sep.}, pages={385–392} }
