Abstract. The aim of the research was to optimize the application of Nagro bioorganic fertilizer. The experiment was carried out on winter rye in the Kuznetsk forest-steppe (southeast of Western Siberia) in 2015–2018. The dependence of the yield and grain quality of winter rye ‘Vlada’ and ‘Tetra Short’ (“Tetra Korotkaya”) on the treatment of seeds and crops was determined. Two types of Nagro fertilizer were used: bio-energy liquid and universal bio-fertilizer. The design of the experiment included 6 options. The first variant was seed treatment with the bio-energy liquid; treatment of vegetating plants with the bio-fertilizer and the bio-energy liquid in the tillering phase. The second variant was seed treatment with the bio-energy liquid; the first treatment of vegetating plants with the bio-fertilizer and the bio-energy liquid, the second treatment of vegetating plants with the bio-fertilizer. The third variant was seed treatment with the bio-energy liquid; the first treatment of vegetating plants with the bio-energy liquid, the second treatment of vegetating plants with the bio-fertilizer. The fourth variant included treatment of vegetating plants with the bio-fertilizer and the bio-energy liquid in the tillering phase. The fifth variant was the first treatment of vegetating plants with the bio-fertilizer and the bio-energy liquid, the second treatment of vegetating plants with the bio-fertilizer. The sixth variant included the first treatment of vegetating plants with the bio-energy liquid, the second treatment of vegetating plants with the bio-fertilizer. The control was crops without the use of bio-fertilizers. The replication was three-fold; the area of the plots was 100 m2. Seeds were treated with bio-energy liquid at a dose of 1 L/t, crops were treated with universal bio-fertilizer at a dose of 1 L/ha and bio-energy liquid at a dose of 0.2 L/ha. The first treatment was carried out in the tillering phase, the second one was carried out in the earing phase. In the experimental variants, the increase in the yield was 4–28%, compared to the control. For Vlada variety the third and fourth variants were more profitable (the level of profitability was 54 and 58%); for Tetra Short variety the third and sixth variants were the best (profitability levels were 58 and 59%). The third and sixth variants of Nagro application were the most economically feasible. In these variants, the yield achieved 2.97 t/ha and 2.81 t/ha, respectively, the protein content was 10.00% and 11.04%, the level of profitability was 57% and 55%. However, the application of Nagro fertilizer on crops of the studied varieties of winter rye was not profitable, as the cost of growing of 1 ton of grain increased on average in both varieties by 5–8%, in Vlada variety by 8–14%, in Tetra Short by 6–8%, relative to the control.
