| description | Azospirillum spp. and Pseudomonas spp. are plant growth promoting rizobacteria that enhance crop growth and productivity. The aim of this article was to compare the effects of Azospirillum brasilense and Pseudomonas psychrophila over early wheat growth in contrasted fertility conditions. This research was carried out under controlled growth conditions combining inoculation and fertility with P and K in sterile substrate. Root length 10 days after sowing (DAS) and above ground and root biomass accumulation after 10 and 40 DAS were evaluated. 10 DAS, when inoculated, radicle length increased on average 8 %, while total biomass increased 6.3 % when inoculated with A. brasilense and 4.9 % when inoculated with P. psychrophila. 40 DAS, both rizobacteria increased root growthin 21 %. 10 DAS and 40 DAS, biomass accumulation was independent from substrate fertility, suggesting that the presence of A. brasilense and P. psychrophila are relevant during implantation and early crop growth. |

Azospirillum spp. y Pseudomonas spp. son rizobacterias promotoras del crecimiento vegetal que mejoran el crecimiento y la productividad de los cultivos. El objetivo de este trabajo fue comparar los efectos de Azospirillum brasilense y de Pseudomonas psychrophila sobre el crecimiento inicial de trigo según condiciones contrastantes de fertilidad. El estudio se realizó en condiciones controladas de crecimiento combinando la inoculación con la fertilización con P y K en un sustrato estéril. Se evaluó el largo de raíces a los 10 días después de la siembra (DDS) y la acumulación de biomasa aérea y radicular a los 10 y a los 40 DDS. A los 10 DDS los tratamientos inoculados presentaron en promedio un aumento del 8 % en el largo de las radículas, mientras que la biomasa total aumentó 6,3 % al inocular con A. brasilense y 4,9 % al inocular con P. psychrophila. A los 40 DDS, ambas rizobacterias aumentaron el crecimiento de las raíces en 21 %. En ambos momentos de evaluación, la acumulación de biomasa fue independiente de la fertilidad del sustrato, lo que sugiere que la presencia de A. brasilense y de P. psychrophila fue relevante durante la implantación y el crecimiento inicial del cultivo.
