Zusammenfassung:In order to know the response of soybean var. Vernal to the effectiveness of microbial inoculants, studies were conducted in the greenhouse, field and validation. Greenhouse eight microorganisms in sterile soil, where increased stem diameter, root biomass and pod number was obtained with the independent or combined inoculation rhizobacteria Bradyrhizobium japonicum [Cell-Tech® (CT)] and the mycorrhizal fungus Rhizophagus intraradices [mycorrhiza INIFAP (MI)]. In a field experiment CT, MI, CT+MI, CT+MI+18-46-00, and absolute control were evaluated. The highest number of nodules per plant was recorded with co-inoculation of CT+MI. CT+MI with or without inorganic fertilization the highest biomass, number of pods per plant grain weight and grain yield was also obtained. In the validation study with additional mechanized planting CT, MI, CT+ MI and control in fertilized soil (18-46-00) or not measured. The results indicated that the highest yields were recorded with CT+MI co-inoculation with or without inorganic fertilization. Although economic analysis showed that the higher profitability of soybean production was coinoculation with non-fertilized soil. The synergistic effect of co-inoculation with CT+MI represents a biotechnological alternative that serves a need for sustainable management of soybeans Con el propósito de conocer la respuesta de la soya var. Vernal a la efectividad de inoculantes microbianos, se realizaron estudios en condiciones de invernadero, campo, así como de validación. En invernadero se compararon ocho microorganismos en suelo estéril, donde se obtuvo mayor diámetro de tallo, biomasa radical y número de vainas con la inoculación independiente o combinada de la rizobacteria Bradyrhizobium japonicum [Cell-Tech® (CT)] y el hongo micorrizógeno Rhizophagus intraradices [micorriza INIFAP (MI)]. En un experimento de campo se evaluaron CT, MI, CT+MI, CT+MI+18-46-00, y testigo absoluto. El mayor número de nódulos por planta se registró con la coinoculación de CT+MI. CT+MI con o sin fertilización inorgánica también se obtuvo la mayor biomasa, número de vainas, peso de grano por planta y rendimiento de grano. En el estudio adicional de validación con siembra mecanizada se midieron CT, MI, CT+MI y testigo en suelo fertilizado (18-46-00) o no. Los resultados indicaron que los mayores rendimientos se registraron con la coinoculación CT+MI, con o sin la fertilización inorgánica. Aunque el análisis económico mostró que la mayor rentabilidad de la produ
