Formation of the phenomenon spectrum of spring soft wheat depending on the pre-sowing treatment of seeds with biological

In our study in 2019-2020, biologics for pre-sowing treatment of spring soft wheat seeds were studied. On average, over two years of research, the duration of the growing season below the control indicator - 80 days was obtained in all variants with the treatment of seed with biological preparations obtained by the VAG method. The maximum duration of the growing season is 4 days lower than the control for the HC 22 variant, 0.5%.
