• Abstract:

  The use of electric motors in seeders aims to increase the efficiency of the dosing mechanisms by eliminating the mechanical transmission, reducing the interference of the set in the productive potential of the crop. With the application of this technology, it is possible to add functions capable of determining the correct application, in quantities and location, of inputs in accordance with the precepts of Precision Agriculture. The use of electric motors provided a reduction in the Coefficient of Variation, failures, in addition to an increase in the number of acceptable plants for the variables, with an average increase in productivity of 335 kg ha^-1. In addition, with the electric motors, the curve compensation function was evaluated, this feature ensures that all lines of the seeder apply the seeds at the same distance, stabilizing productivity in the same sowing pass. The survey showed a productivity increase of around 13.3% greater than not using the function. The results of the analyzes indicated, on average, an increase in productivity of 276.5 kg ha-¹ for electric motors, converted into R$ 829.50 per hectare.
