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 |
