“…Enough experience of successful application in the pre-sowing treatment of seeds of agricultural plants with electromagnetic fields of various frequencies, a corona discharge field, an electrostatic field of alternating voltage, and electric pulse fields has been accumulated [10][11][12]. The undoubted advantages of these methods, of course, is the cheapness of processing, but there are also disadvantages that are a deterrent to industrial implementation, one of which is the need to conduct experiments and establish optimal parameters (intensity, time, frequency, pulse repetition period) for each crop, depending on physiological characteristics, these parameters may be different [13,14]. Incorrectly selected electrophysical parameters can lead not only to the plant inhibition in development and a decrease in yield, but also to complete death.…”

The article reflects the results of scientific studies of responsiveness to germination and germination energy of sunflower hybrid seeds to the electrophysical effect of a pulsed electric field with different intensity and exposure time. Seeds of sunflower hybrids NK Neoma and ES Petunia were taken for research. During the experiments, pulse field intensity of 2, 4, 8, 10 kV/cm, pulse duration of 40 microseconds, electric field exposure time of 15, 30, 60, 90, 105 seconds were taken. Optimal modes for processing sunflower seeds with a pulsed electric field have been experimentally established to increase the conditioned qualities – seed treatment for 90 seconds at a field intensity of 6 kV/cm or treatment at a field intensity of 8 kV/cm for 60 seconds.
