 Corn is among the main grain crops grown in Brazil, standing out for its high yield potential. The increase in productivity achieved by the crop is due to genetic improvement, correct management practices and adhesion of new technologies available in the market, among them is the use of products with biostimulant action. The objective of this study was to evaluate the effect of seed and leaf applied biostimulant packages in order to analyze the vegetative and reproductive development variables of the DKB 230 (Dekalb) corn hybrid. The experiment was conducted in the agricultural year of 2018/2019 in the experimental area of the Federal University of Santa Maria campus of Frederico Westphalen / RS. The experimental design was randomized blocks, with five biostimulant treatments, namely, Vigor S®, Potassium with algae® and Grains +®; Vigor G®, Potássio com algas® and Grãos +®; Vigor SS®, Potássio com algas® and Grãos +®; Stimulate®, Start® and Mover®; and control (without any biostimulant), with four repetitions. Plant height, stem diameter, average number of rows of grain per ear, weight of one thousand seeds and grain yield were evaluated. According to the results obtained, the biostimulant packages did not influence the evaluated variables, under the conditions of the experiment.
