The objective of this study was to evaluate the use of rooters in corn using hybrid cultivar MG545PWU (Power Core Ultra). The experiment was installed on a Farm “Chácara Santa Luzia” in the municipality of Rio Verde, Goiás, Brasil, between April and June 2022. The experiment was carried out in pots with a 2:1:1 ratio, with a mixture containing 2 kg of substrate, 1kg of local soil and 1kg of medium-textured sand. The experiment was carried out in a randomized block design with five replications and four treatments. The Treatment was called a control, without adding rooters; Treatment 2 rooting A with addition of 4 mL; Treatment 3 rooting B with addition of 4 mL and Treatment 4 rooting C with addition of 2 mL. Three seeds of corn cultivar MG545PWU were sown in a three-cm depth pot. During the conduct of the experiment, the treatments were irrigated every 3 days after implantation. After 15 days of emergence, thinning was performed, leaving only one germinated plant with greater vigor in each pot. After 30 days with plants in V8, the stem diameter, root length (cm), plant height and fresh and dry mass of the aerial part (g) were measured. As a positive effect, it was observed that rooter B exhibited good results for the variables analyzed in the hybrid cultivar MG545PWU (Power Core Ultra) when compared to rooters A and C and control.
