| description | The objective of this study was to evaluate the effects of inoculation and co-inoculation with Bacillus subtilis and Pseudomonas fluorescens on carrots with reduced nitrogen use. 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 P. fluorescens 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 P. fluorescens 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, Pseudomonas fluorescens can be recommended as a plant growth-promoting microorganism in carrot cultivation. |

El objetivo de este estudio fue evaluar los efectos de inoculación y co-inoculación de Bacillus subtilis y Pseudomonas fluorescens en plantas de zanahoria con uso reducido de nitrógeno. Se realizó un experimento de campo, con cinco tratamientos y cinco repeticiones, evaluando las respuestas de crecimiento y rendimiento de la zanahoria a la inoculación. Las respuestas sobre la altura se observaron solo dos semanas antes de la cosecha, pero el número de hojas se vio afectado principalmente desde el comienzo hasta la mitad del ciclo de cultivo. Aunque la masa de brotes frescos se vio afectada negativamente por los tratamientos de inoculación, la masa de brotes secos no respondió a las rizobacterias. La longitud de las raíces inoculadas con P. fluorescens o co-inoculadas con ambas bacterias aumentó de 21 cm, sin inoculación, a 25 cm. Los valores del volumen de la raíz y la masa seca fueron los mismos en todos los tratamientos. Sin embargo, la masa de raíces frescas mejoró entre 70 y 81.8% por P. fluorescens y co-inoculación, respectivamente. La mayoría de las respuestas positivas a la inoculación se observaron con niveles reducidos de nitrógeno, lo que sugiere el potencial de estas cepas de rizobacterias para ser utilizadas en prácticas agrícolas de insumos reducidos. Además, nuestros hallazgos respaldan la recomendación de Pseudomonas fluorescens como microorganismo promotor del crecimiento de las plantas utilizado para el cultivo de zanahorias.
