Abstract The article found that the highest yield of lentil seeds was obtained by combining the application of mineral fertilizers and inoculation (variantР30К40+N60+Mo). The combination of seed inoculation with the application of mineral fertilizers activates the growth and development of plants and contributes to an increase in productivity by 0,25–0,92 t/ha, respectively, up to the control option without fertilizing. Due to the introduction of phosphorus and potassium fertilizers in a dose of P30K40, on average over the years of research without inoculation, the yield increase to the control is 0,2 t/ha or 10 %, and during inoculation – 0,25 t/ha or 11 %. As a result of improving the conditions of mineral nutrition due to the introduction of nitrogen fertilizers on a phosphorus-potassium background without inoculation at doses of 30 and 60 kg/ha d. obtained in accordance with the increase of 0,30 and 0,43 t/ha or 14 and 19 %, and during inoculation – 0,72 and 0,79 t/ha or 35 and 36 %. Inoculation of the studied strain of nodule bacteria in the variant with 30 kg/ha d. nitrogen fertilizers and ammonium molybdate against a phosphorus-potassium background formed a yield increase of 0,63 t/ha, respectively, or 29 % more in control. During inoculation, the replacement of ammonium nitrate with ammonium sulfate with the addition of ammonium molybdate (variantР30К40+N30S34+Mo) increases the yield of lentils by 0,83 t/ha, or by 37 % compared to the version without fertilizers. Inoculation of lentil seeds with nitrogen-fixing bacteria preparations should be mandatory agrotechnological approach on podzolized chernozem. It is rational to use Rizostim against phosphorus, potassium and molybdenum fertilizers when applying 60 kg/ha of nitrogen fertilizers under pre-sowing cultivation.
