ResumoIn addition to essential macronutrients and micronutrients, bioregulators, biostimulants or bioactivators are being increasingly used on agricultural crops with important outcomes. Therefore, improved knowledge on the functioning of these chemicals on plants is needed. Based on the assumption that foliar fertilizers applied at specific times promote soybean growth, development and yield, the aim of the present study was to evaluate the biometric, biomass, physiological, nutritional and grain yield parameters to increase knowledge about specific fertilizers applied alone or in combination and at different stages of soybean growth and development. The present study was performed in partnership between the Goiano Federal Institute (Instituto Federal Goiano), Campus Rio Verde, state of Goiás (GO), Brazil, and the company Tecno Nutricao Vegetal e Biotecnologia Ltda. A randomized block experimental design was used with four replicates. The biometric, physiological, nutritional and yield data were subjected to analysis of variance followed by Tukey’s test when significant differences were found at p 0.05 using the SISVAR software. In the emergency and early use of Tonik combined with Nodumax and PreventCoMo, in the vegetative phase, the Lumix combined with Vivat or VivatMn in the reproductive stage of flowering, 2 application Tripper combined with VivatB at a dose of 500 ml·ha-1 and reproductive phase of grain filling, 2 application Apport at a dose of 500 g·ha-1 gave the best results.
