Abstract

Abstract. It is possible to increase crop yields and product quality through the use of electrophysical methods of pre-sowing seed treatment, among which pre-sowing seed treatment in a magnetic field is promising.

For successful introduction of magnetic seed treatment in production it is necessary to establish mode parameters of treatment and their optimum values. To do this, it is necessary to establish the effect of the magnetic field on the change in activation energy during pre-sowing seed treatment.

The aim of the study was to determine the change in activation energy during pre-sowing treatment of crop seeds in a magnetic field.

To determine the change in the activation energy, the change in the biopotential of the seed during its treatment in a magnetic field was experimentally investigated by the experimental planning method.

It was found that the change in seed biopotential depends on the square of the magnetic induction and the velocity of the seed in a magnetic field.

An analytical expression was obtained that relates the change in activation energy to the change in seed biopotential, which made it possible to establish the dependence of the change in activation energy on the treatment parameters.

It was found that the greatest seed biopotential and activation energy change at a magnetic induction of 0.065 T, a magnetic field gradient of 0.57 T/m and a velocity of 0.4 m/s. Under this mode of pre-sowing seed treatment of agricultural crops, the activation energy changes by 3.1 - 5.7 kJ/g-eq.

 Key words: magnetic induction, seed velocity, biopotential, activation energy, crops
