Abstract The article covers the issues of humidity of plants of the miscanthus depending on the MaxiMarin absorbent use during the period of rhyzome seeding. t was established that the absorbent introduction into the soil before planting with rhyzome contributed to a better supply of plants with moisture. In all phases of growth and development of plants, soil moisture in the variant using an absorbent was significantly higher than control - without the use of absorbent for both seasons. There was no significant difference in soil moisture, depending on the type of absorbent, but it was advisable to note that the soil moisture content was significantly higher compared to the control with absorbent granules, and soaking with rhyzomein the gel did not provide a reliable increase in moisture content compared with the control, there was only a tendency to increase it. Over the research years and the stages of growth and development of the miscanthus, the "absorbent" factor has a different effect on soil moisture. But due to the lack of moisture in the phase of the release of the tube in 2017, the impact of this factor was the largest - 61%. During the second planting season, when the average daily air temperature was 10 ° C or more, the soil was well warmed, and the moisture content was lower than during the first period of planting, the effectiveness of the absorbent improved. In all stages of the growth and development of the Miscanthus, the moisture content of the soil was significantly higher than the second seeding period, compared to the first period. The introduction of the MaxiMarin absorbent into the soil before planting with rhyzome contributed to a better supply of plants with moisture not only in the first year of vegetation, but also in the second. In all phases of growth and development of plants, soil moisture content for the application of absorbent granules into the soil and the joint use of granules and gels of absorbent soil moisture was significantly higher than control - without the use of absorbent for both seasons.
