It was established that during the growing seasons of soybeans of the GTK, humidity and heat supply (0.16 in 2024 and 0.42 in 2025) corresponded to severe drought conditions; The TVP of soybeans of the Siverka variety was 94-97 days with an extension of three days for direct sowing. Against the background of traditional plowing and surface treatment, the highest and highest indicators of linear growth of plants - 63.8-73.9 cm and stand density - 61.0-63.0 pcs./m2 were formed. The most optimal conditions for the density of podzolized chernozem in a layer of 0-30 cm: against the background of long-term plowing - 1.22-1.25 g/cm3, long-term surface treatment - 1.23-1.27 g/cm3 with a total porosity of 49.82-55.54% and 47.52-58.21% and aeration gaps - 24.43-47.15% and 22.91-50.28%. The most effective option according to the set of indicators of the crop structure, on average, was surface long-term cultivation with the application of fertilizers in a dose of N60P60K60, which provided the highest indicators: individual productivity - 7.01 g/plant, number of beans - 22.8 pcs./plant. and seeds - 43.7 pcs./plant, weight of 1000 grains - 166.7 g and the maximum productivity level - 2.04 t/ha with an increase in additional yield of 0.50 t/ha (32.5%), yield of protein per unit area - 0.84 t/ha, oil 0.43 t/ha. Under arid conditions, the appropriate system from an economic point of view is long-term surface tillage and the optimal dose of N45P45K45 fertilizers, which provided the maximum level of profitability - 126.9% at the lowest cost - 5.07 thousand UAH / t and conditional net profit indicators - 17.18 thousand UAH / ha, with a yield of 1.92 t/ha.
