The effectiveness of the use of absorbent granules for growing sugar beet seeds under conditions of unstable moisture was investigated. It was determined that the introduction of MaxiMarin absorbent granules into the soil before planting sugar beet uterine roots contributed to a better supply of moisture to the plants. In all phases of growth and development of seeds, soil moisture with the absorbent was significantly higher compared to the control variant, where it was not applied. Optimal moisture supply contributed to better use of mineral nutrients. When the absorbent was applied before planting the seeds at the end of the growing season, the content of mobile forms of phosphorus and potassium in the soil was lower by 13 and 20 mg/1 kg of soil, respectively. The positive effect of the absorbent application on the intensity of seed growth and development was studied. All phases of seed development occurred earlier compared to the control. It was determined that the application of the absorbent affected the biometric parameters of the seeds. On average, over three years, when the MaxiMarin absorbent was applied, the seed heads were 58.2 cm higher, and the number of first-order shoots on which seeds of sowing fractions were formed was 1.2 times higher. The density of fruit placement on the shoots of the seedpods was also higher. For every 10 cm of shoots, 9.0 more fruits were formed. The increase in biometric parameters due to the introduction of absorbent granules into the soil in combination with soil, climatic and agronomic conditions provided an increase in seed yield by 0.15 t/ha and an increase in germination energy and germination by 4 % (NIR0.05 = 1.7 %) compared to the control
