The article provides data on the impact of high-voltage current of electric spark discharges on the culture of gummosis located on the surface of a cotton seed, special electrodes were made to determine electrical resistance, a method for conducting research experiments was developed, the liquid was from the outside of the peel, an electronic megohmmeter was used for measurement, for conducting experiments have drawn up a block diagram of the research methodology. The analysis of the works shows the absence of any data on the electrophysical parameters of the moistened pubescent seeds before sowing. Therefore, the study of the electrophysical characteristics of sown moistened pubescent cotton seeds is of scientific and practical importance for substantiating the operating parameters of electric spark treatment. Before sowing, pubescent cotton seeds are sorted (low-quality seeds are separated up to 10-15%), then moistened. The morphology and the mechanism of wetting cotton seeds are reflected in the analyzed works, and in the sectional view of the cotton seed. In the process of moistening, the main site of moisture absorption at the initial stage of moistening after backfilling is chalaza. Together with moisture, oxygen also enters the crumpled cotyledons, after which the root makes its way through the micropile. The peel protects the seed core from excessive oxygen supply. At the same time, the skin of the seed prevents the rapid flow of moisture into the seed. An electrical circuit is presented that ensures the completeness of seed treatment. And also the materials are given regarding the “electric hardening” of the water being humidified. Preconditions have been made for the automation of the seed moistening process.
