Systematic plowing provided a slightly lower (by 0.02-0.07 t/ha) yield level - 2, 27-3.15 t/ha, which did not have a significant difference between treatments (according to NIR05 for factor A – 0.07 t/ha, for factor B – 0.06 t/ha). A significantly lower yield was obtained in the first year of No-till cultivation: 2.18-2.92 t/ha against the background of plowing, which is less by 0.09-0.23 t/ha (4.0-7.3%) and 2.17-2.94 t/ha against the background of unchanged surface cultivation, which is 0.10-0.21 t/ha (4.4-6.7%) less compared to the control (systematic plowing). The background application of mineral fertilizers (N45P45K45) provided a yield of 2.58-2.76 t/ha with a significant increase of 0.40-0.47 t/ha (18.3-20.5%) compared to the control. Variants with additional two-time foliar fertilizing with potassium humate in the background provided the maximum level of yield of 2.92-3.22 t/ha and an additional yield increase of 0.74-0.93 t/ha (33.9-40.6%). To obtain highly productive agrocenoses of soybeans, the technology was more effective against the background of unchanged surface cultivation and systematic plowing with the background application of N45P45K45 in a complex with two-time foliar fertilizing with potassium humate in the phase of leaf formation and the beginning of flowering with a consumption rate of 2.0 l/ha, which ensured a significant increase in seed yield and economic advantages in increasing the profitability and profitability of production: conditionally net profit – 28,949 and 27,539 UAH/ha for the lowest production cost – 4,010 and 4,257 UAH/t and profitability levels – 224.2 and 205.3%.
