On the basis of research of winter rye productivity dependence of Vlada and Tetra short cultivar from exposure of seed treatment and sowing with bioorganic nano-fertilizer Nagro in Kuznetskaya forest steppe of south-east in West Siberia (2015–2018 years), there was found out increasing of yield activity respectively to control (sowings without fertilizer) for Vlada cultivar – 15-28% and Tetra short – 4-13%. Number of falling increased for 5-23%. Wasn’t spotted correlation between hydrothermal conditions of vegetation and influence of biologics on studied productivity index.

The results of the study carried out in the northern forest-steppe foothills of the SouthEast of Western Siberia in 2014-2017 in order to assess the impact of seed treatment and winter rye crops for vegetation by bioorganic nano-fertilizer NAGRO on the grain yield and quality and to identify the most effective option are presented. Vlada and Tetra short varieties were studied, treated according to six experimental options. Two types of biofertilizers were used: bioenergetics NAGRO – for daily treatment of seeds and crops and NAGRO universal – for treatment of crops during vegetation. Control – seeding without the use of bio-fertilizer. Presowing seed treatment carried out by NAGRO bioenergetics with the norm 1 l/t, the crops by NAGRO universal with the norm 1 l/ha and by the bioenergetics – 0.2 l/ha. Working solution volume is 250 l/ha. The increase in yield on the variants of the experiment with respect to the control of Vlad varieties by 7 – 20%, Tetra short varieties by 7 – 15%. More efficient yields were the crops with the treatment options in the variety of Vlada – three (seed treatment with bioenergetics, 1st treatment on vegetation – bioenergetics in the phase of tillering in the spring, the 2nd processing – universal in the earing phase); the varieties of Tetra short - two (seed treatment with bioenergetics, 1st treatment on vegetation – universal + bioenergetics in the phase of tillering in the spring, the 2nd treatment – universal in the earing phase). The greatest number of falls was observed in Tetra short variant two, for Vlada - in variant three.
