Abstract: Purpose. To establish the influence of bacterial-mineral fertilizer on the formation of symbiotic productivity of soybeans in the conditions of the Right-Bank Forest-Steppe of Ukraine and to study the agroecological principles of the application of these methods. Methods. The research was conducted at the "Salyvonkivske" enterprise on typical low-humus chernozem, utilizing early-maturing 'Vilshanka' and midmaturing 'Suzirya' soybeans. P60K60 fertilizers were applied during primary tillage, alongside split nitrogen applications pre-sowing and at budding. Seeds were inoculated pre-sowing with 'Phosphonitragin', a preparation containing nodule and phosphate-mobilizing bacteria. Results. It was found that the starting doses of nitrogen (N15-30) increased the number of nodules by 89.3–164.2%, while the rate of N45 had a less pronounced effect (24.7–27.3%). Bacterization itself provided an increase in the number of active nodules by 174.1–210.1%. The most favorable conditions for soybean-rhizobial symbiosis were created by the combined action of inoculation and the retail application of N30Р60К60 + N15. Under such conditions, the increase in active symbiotic potential reached 82.9–90.2%, and the accumulation of biological nitrogen was 118.8–130.3 kg/ha, which exceeded the control indicators by 71.3–75.6%. Conclusions. It was established that in the conditions of the Right-Bank Forest-Steppe of Ukraine, the highest productivity in terms of fixed nitrogen accumulation is formed by the early-ripening variety Vilshanka (124.2 kg/ha) and the mid-ripening variety Suzir’ya (130.3 kg/ha). This level is ensured by the use of fertilizer N30P60K60 with top dressing N15 in the budding phase and seed inoculation. The obtained data allow us to significantly improve varietal technologies for soybean cultivation through the integrated use of biological products and the retail application of nitrogen fertilizers.
