Methods. Field,<br>laboratory, and statistical. Results. The maximum number and weight of active nodules on the lentil roots were<br>formed in the stage of bean filling when the plant’s need for nitrogen was the highest. Seed inoculation with<br>formulation Rizohumin contributed to a 5.3 times increase in the number of active nodules in the budding stage,<br>4.5 times in the flowering stage, and 3.8 times in the bean-filling stage compared to the control treatment. The best<br>indicators of active symbiotic potential demonstrated the treatment with seed inoculation with Rizohumin and the use<br>of phosphate-mobilizing formulation Polymixobacterin and Azohran B in combination with foliar dressing using<br>Alga 600. In the same treatments, in the flowering stage, the maximum content of leghemoglobin in the fresh<br>mass of nodules (5.58 and 5.50 mg/g) was obtained. In the flowering stage, plants formed the maximum leaf area<br>(40 300 m2<br>/ha) in the treatments with Rizohumin, Azogran B, and Alga 600. When using a combination of<br>Rizohumin, Polymixobacterin and Alga 600, 128.0 kg/ha of nitrogen, 43.4 kg/ha of phosphorus, and 60.8 kg/ha<br>of potassium was needed for yield formation. At the same time, under the joint application of Rizohumin,<br>Azorgan B and Alga 600, the need was 118.0 kg/ha, 40.0 kg/ha, and 56.0 kg/ha, respectively, which corresponded to<br>the maximum indicators of the nutrient uptake in the experiment. The use of Rizohumin + Azogran B +<br>+Alga 600 resulted in the lentil yield of 1.79 t/ha; whereas in the treatments with Rizohumin + Polymixobacterin +<br>+Alga 600, the maximum yield was obtained (1.95 t/ha).</p>}, number={4}, journal={Научный журнал «Вестник НАН РК» }, author={Prysiazhniuk O.I. and Slobodianiuk S.V. and Topchii O.V. and Sukhova H.I. and Karpuk L.M. and Kryvenko А.I. and Svystunova I.V. and Pavlichenko A.A.}, year={2020}, month={авг.}, pages={81–89} }
