The possibilities of increasing the productivity of soybeans grown on irrigation after application of mineral fertilizers and biological nitrogen in the steppe zone of the Central Ciscaucasia have been studied. It was found that, on average, over 3 years of research, the highest yield in the experiment was when growing the mid-season variety Selecta 302 with the introduction of ammophos in doses of N12P52 and N24P104 in combination with pre-sowing inoculation of seeds with rhizotorfin - 2.68 –2.74 t / ha, which is more than in standard variant (Vilana variety) by 0.11-0.12 t / ha. Compared to the control (without fertilizers and rhizotorfin), the increase was 0.21–0.27 t / ha, or 8.5–10.9%. It is economically feasible to grow the soybean variety Select 302 on irrigation with the application of mineral fertilizers at a dose of N12P52 and pre-sowing inoculation of seeds with rhizotorfin. The profitability was 68.8%.
