Evaluation of endophytic growth promoting bacteria in quinoa cultivation
subject: Bacillus sp, bacteria interaction, evaluation, in vitro compatibility, viability
description: The present research aims to evalúate the interaction of simple and combined endophytic bacteria, to develop new bioinoculants formulations, over the agronomic variables of the quinoa cultivation, to genérate viable alternatives for the Andean farmers. A powder product was obtained by mixing a bioinoculants formulation developed with three single and combined strains of Bacillus sp. and an inert substrate, to be compared in a greenhouse/in vitro environment with a commercial product (TRICOBAL) as a positive control group and normal soil (without inoculants) as a negative control group. The following treatments were identified: Bacillus pumilus (Bp), interaction between Bacillus pumilus and Paenihacillus polymyxa (Bp + Bv54) and the combination of Bacillus pumilus, Bacillus suhtilis and Paenihacillus polymyxa (Bp + Bs + Bv54) with prominent results on: plant height (104.14 cm), panicle height (34.32 cm), roots weight (5 grs.) and grain performance; demonstrating that these native strains significantly promote the growth of quinoa plants in relation to the commercial product (TRICOBAL). In addition, it was determined that in an in vitro environment the three used strains of Bacillus can coexist.
