Corn (Zea mays L.) is a crop of world importance, however, one of the problems present during its development is the lack of nutrients or the presence of these in a form not available to the plant. Because of this, the objective of this review article is to gather information on the influence of different dosages of mycorrhiza and diazotroph biofertilizers on the corn crop. A meticulous bibliographic research was carried out, detailing the methods used by various authors; Among the most repetitive and significant factors are the use of mycorrhizae and nitrogen-fixing bacteria plus fertilization with P, the following treatment stands out: 200 gr ha−1 (using mycorrhizae and nitrogen-fixing bacteria); the common response variable of the authors mentioned in methodology was grain yield. The results obtained by the majority of authors show that grain yield improves significantly in the interaction of mycorrhizae and diazotrophs plus chemical fertilization; As a result of the aforementioned treatment, the yield of corn kg ha−1 was increased by 37%, by virtue of these results it is concluded that the most appropriate thing would be to take it into account to apply it on the corn crop. Keywords: Inoculants, Nitrogen Fixing Bacteria, Symbiotic Fungi. Resumen El maíz (Zea mays L.) es un cultivo de importancia mundial, sin embargo, uno de los problemas presentes durante su desarrollo, es la falta de nutrientes o la presencia de estos en forma no disponible para la planta. Debido a esto, el objetivo de este artículo de revisión es recopilar información sobre la influencia de las diferentes dosificaciones de biofertilizantes a base de micorriza y diazótrofos sobre el cultivo de maíz. Se realizó una minuciosa investigación bibliográfica, detallando métodos utilizados por varios autores; entre los factores más reiterativos y significativos están el empleo de micorrizas y bacterias fijadoras de nitrógeno más la fertilización con P, sobresaliendo el siguiente tratamiento: 200 gr ha−1 (usando micorrizas y bacterias fijadoras de nitrógeno); la variable respuesta en común de los autores mencionados en metodología fue el rendimiento del grano. Los resultados obtenidos por la mayoría de autores muestran que el rendimiento del grano mejora significativamente en la interacción de micorrizas y diazótrofos más la fertilización química; producto del tratamiento mencionado anteriormente, se aumentó un 37% el rendimiento del maíz kg ha−1, en virtud a estos resultados se concluye que lo más adecuado sería tomar en cuenta para aplicarla sobre el cultivo de maíz. Palabras Clave: Inoculantes, bacterias fijadoras de nitrógeno, hongos simbiontes.
