    Beauveria is known not only for its ability as a biopesticide but also for its potential to enhance plant growth and development by acting as an endophyte. It has been shown that this fungus can increase plant resistance to abiotic and biotic stress, improve nutrient absorption, and promote more vigorous growth. The present study aimed to evaluate the performance of Beauveria spp. as an endophytic fungus in maize, as well as its impact on seed germination and early seedling growth. Two types of Beauveria spp. (native and commercial) were used in this study at concentrations of 1 x 10^4, 1 x 10^6, and 1 x 10^8 conidia/mL, applied at intervals of 3, 7, and 15 days.The results of this study show that maize seeds treated with Beauveria spp., both native and commercial, at the mentioned concentrations, recorded germination rates similar to the control, suggesting that the fungus does not negatively affect the germinative capacity of the seeds. In the analysis of plant growth, conducted over a period of 42 days (6 weeks), it was demonstrated that treated plants developed more rapidly than untreated plants; however, they did not show significant differences compared to the control. This suggests that, although Beauveria spp. may have a positive effect on plant growth, the observed effect was not significant enough to be considered relevant in this study.Regarding endophytic colonization, it was found that Beauveria spp. significantly colonized maize plants when applied every 3 and 7 days at a concentration of 1 x 10^8 conidia/mL. These results indicated that the frequency of application affects the degree of endophyte colonization. It is recommended to continue researching different concentrations and application frequencies of Beauveria spp. to improve its use and support more sustainable agricultural practices.
