RESUMO:

The emerging demand for reducing dependence on mineral fertilizers and the need for sustainable agriculture development point to the use of microorganisms as a viable alternative to the producer in order to reduce mineral fertilization. The objective of this study was to evaluate the potential of nine microbial isolates to promote growth through two methods of inoculation (irrigation and immersion) in emerald grass seedlings. The experiment was carried out in a completely randomized design in a 2x8 factorial scheme, with four replications. The treatments consisted of two methods of application (Rega and Immersion) x 9 microorganisms isolated and in control combination (T1 (water / control), T2 (Pseudomonas fluorescens- BRM32111), T3 (BRM32113), T4 (R-92) , T5 (R-61), T6 (R-58), T7 (mixtures of Pseudomonas fluorescens (BRM32111) and Burkholderia pyrrocinia (BRM32113) and T8 (mixtures of Trichoderma asperellum-UFRA-T.06, UFRA-T.09 , UFRA-T.12 and UFRA-T.52) .The irrigation application method, independent of the isolate, provided a 64% increase in total biomass, whereas by immersion the increase was 35% in relation to the control. In this study, the BRM32111 and BR32113 isolates measured increases of 104% and 122%, respectively, and the root dry mass and plant height variables were sufficient to explain the highest percentage of variation in the data. of 156% and 92% in dry mass of root and height of plants, respectively, in relation to the control. The rhizobacterium BRM32113 proved to be competent in inducing the growth of the emerald grass plant and could be inserted into an ecologically sustainable nutritional management program with potential for commercial use.
