In order to evaluate the effect of Azospirillum brasilense and mycorrhizal fungi in the soil on the nutrition of the yacon crop (Smallanthus sonchifolius [(Poeppig & Endlicher) H. Robinson]), determinations of agronomic parameters and the health status of the plants were carried out, under field conditions. The tests were carried out, at the time of the implantation of the culture: the propagules were inoculated with A. brasilense and with native mycorrhizal fungi, generating four treatments including the control and the co-inoculation of the consortium of the microorganisms under study (T0: control without inoculation; T1: inoculation with native A. brasilense; T2: inoculation with native mycorrhizal fungi and T3: joint inoculation with A. brasilense and native mycorrhizal fungi). The results indicate that co-inoculation with A. brasilense and with native mycorrhizal fungi, increased significantly the growth of plants in height, leaf area, biomass, dry matter and yields, in field production. It was determined that the application of the selected microorganisms has a promoting effect of plant growth, increasing growth and productivity of the cultivation of yacon.
