LOVAISA, N.C. et al. Effect of inoculation with plant growth promotingbacteria in corn plants (Zea mays L.). Rev. agron. noroeste arg. [online]. 2018, vol.38, n.1, pp.33-38. ISSN 0080-2069.
Although there are numerous studies of the interaction between corn plants (Zea mays) with Azospirillum brasilense, reports about the interaction with Gluconacetobacter diazotrophicus are scarce. The aim of this work was to evaluate the effect of inoculation with microorganisms that promote plant growth corresponding to the bacterial species of A. brasilense REC3 and G. diazotrophicus PAL5 on the development of maize plants. Trials were carried out in which the microorganisms were inoculated individually or in combination in corn plants of the variety Leales 25, which were sowed in two soils with different degrees of fertility. Variables measured in plants were relative values of Soil Plant Analysis Development (SPAD) and length and root surface. Results revealed that A. brasilense REC3 and G. diazotrophicus PAL5 had superior effects than the control. Only A. brasilense REC3 generated a significant increment in biomass of corn plants compared to other treatments in both types of soils.
