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.

SUMMARYInoculatingZea mays(three cultivars),Sorghum bicolor, Panicum miliaceumandSetaria italicawith nitrogen-fixing bacteria of the genus Azospirillum in Northern Negev and Bet Shean Valley field experiments resulted in significant increases in yield of grain and foliage of commercial value. It was concluded that inoculating summer cereal crops in Israel may save valuable nitrogen fertilizer.

This research is the phenotypic characteristics and grouping of hybrid waxy corn Zea mays L. product of the top cross had been carried out in the experimental plant Indonesian Cereals Research Institute (ICERI) in Maros South Sulawesi. This research aims to determine the phenotypic characters of the hybrid of waxy corn Zea mays L. product of the top cross and grouping based on its phenotypic characteristics. This research used a randomized block design (RBD) with 17 th treatments (corn strains) and three replications. Waxy corn strains used were: URI 1 (G8), G8G1, G8G2, G8G3, G8G4, G8G5, G8G6, G8G7, Soppeng (G10), G10G1, G10G2, G10G3, G10G4, G10G5, G10G6, G10G7, and Paramitha.. All data (qualitative and quantitative) are arranged in binary tables and grouped using the NTSYST program. The observations show that the data obtained comes from 14 quantitative characters and 17 qualitative characters. Quantitative data from 14 characters were tested and the results of 10 characters were significantly different and the other 4 were not significantly different. The grouping results show that the 17 corn strains studied formed 3 groups at the similarity coefficient of 0.76. Soppeng's corn is different from the others.
