• Abstract:

  The objective of this study was to evaluate the germination and initial establishment of the MG580PW hybrid in response to the application of fertilizers and biostimulants used in seed treatment. The experiment was conducted in the municipality of Paraúna (GO) in 2025. The seeds were treated according to manufacturers’ recommendations and grown in a substrate composed of soil, sand, and commercial material in a 3:2:1 ratio. The experimental design was a completely randomized block design, with four treatments and five replicates. The variables analyzed included germination, shoot and root length, as well as fresh and dry weight, with the data subjected to ANOVA and the Scott-Knott test at the 5% level. The seedlings showed good germination in all treatments, with rates ≥ 80% 5 days after sowing and above 90% in the remaining treatments. Regarding development, no significant difference was observed among the treatments. It is concluded that the products evaluated in this trial promoted the initial vigor and establishment of maize seedlings, highlighting the potential of fertilizers and biostimulants in seed treatment to improve the initial performance of the MG580PW hybrid.
