It was found that in the fourth year of vegetation in the flowering phase, the average height of millet plants in the experiment was 148.3 cm, and in the liming var-iants, the influence of the factor contributed to the formation of 3.4 cm taller plants. While the role of moisture in the vegetation process increased, plants were formed 7.6 cm taller than the control plants on the variants of application of the MaxiMarin ad-sorbent, and before harvesting, this difference even increased to 8.8 cm. Also, during this period, the effect of foliar fertilization increased. which contributed to obtaining a 9.6 cm higher height of rod-shaped millet. The effect of foliar fertilization in the late phases of plant development was consistently high, and the best height at the time of harvest was observed in crops with a combination of soil liming, 25% of the require-ment, application of MaxiMarin granulated adsorbent and foliar fertilization with hu-mates Potassium humate (Gumifield) and anti-stress AminoStar - 170 cm. Millet mil-let plants yield 57.5 kg/ha of nitrogen, 39.3 kg/ha of phosphorus and 118.7 kg/ha of potassium, and dead above-ground and underground biomass returns 25.0 kg/ha of nitrogen, 17.6 kg /ha of phosphorus and 55.8 kg/ha of potassium. And the applica-tion of additional agrotechnical measures, in general, leads to growth, both removal and return of biogenic elements. In general, rod-shaped millet crops in the fourth year of vegetation lost part of their biomass during cultivation, and in this way up to 43.6% of nitrogen, 44.7% of phosphorus and 47.0% of potassium were returned to the soil from the total removal of the crop.
The application of soil liming, 25% of the requirement (1.6 t/ha) and the in-troduction of an adsorbent (MaxiMarin granulated) 30 kg/ha served as the optimal basic option for the formation of high indicators of the leaf surface area of millet crops under foliar feeding of plants. Thus, the effect of potassium humate (Gumi-field) 50 g/ha + Antistress AminoStar, 1.0 l/ha was enhanced against the background of soil liming, 25% of the need in combination with the use of an adsorbent (Maxi-Marin granulated) and in the third year of vegetation, the leaf area in in the flowering phase was 48.8, and in the fourth - 60.4 thousand m2/ha.
It was established that the photosynthetic potential in the first year of vegeta-tion was on average 1.47 thousand m2/ha×day according to the experiment, and in the second year it increased to 3.01 thousand m2/ha×day, while in 2021 the crops formed 3 .78 thousand m2/ha×day, and in the conditions of 2022 – 4.64 thousand m2/ha×day. The best values according to the options were obtained with the com-bined foliar fertilization of plants Potassium humate (Gumifield) 50 g/ha + Antistress AminoStar, 1.0 l/ha against the background of lime and adsorbent, which corre-sponded to 1.70 thousand m2/ha×day, 3.47 thousand m2/ha×day, 4.38 thousand m2/ha×day and 5.41 thousand m2/ha×day.
Liming was most effective in the first year of vegetation, when the root sys-tem was actually in the zone of lime application, which contributed to the formation of 0.12 t/ha more dry matter. In our opinion, the systematic but insignificant increase in the impact of this agricultural measure on the fourth year of vegetation is connected with the increase in the level of moisture in the last two years. While in the first two growing seasons, 44.5 and 44.9 mm of moisture fell, in 2021 the difference was only 7.6, and in 2022 - 13.5 mm less than the annual amount. The increase in the regime of soil colloid hydration most likely increased the activity of acidity and its influence on the growth and development of millet plants.
In the fourth year of vegetation, the influence of all factors of the experiment on the formation of productivity of millet plantations significantly increased. It was determined that the yield was 6.87 t/ha on the option of soil liming and application of MaxiMarin adsorbent granulated and foliar fertilizing Potassium Humate (Gumifield) 50 g/ha + AminoStar anti-stressor, 1.0 l/ha.
It was studied that in the variants where 25% of the required amount of lime was applied to the soil, the ash content in the leaves of millet plants was 9.54%, and in the stems - 2.87%, that is, it was 1.91% and 1.41% less than on options without lim-ing. At the same time, the use of other influencing factors showed a significant de-crease in the ash content, but it was within the experimental error.
It was established that in the fourth year of cultivation, against the back-ground of the application of lime with the addition of MaxiMarin granulated adsor-bent and foliar fert
