The influence of biological preparations presowing seed treatment on the spring soft wheat yield formation in conditions of Altai Krai Ob region

Abstract

The article presents the results of studying the effect of growth-stimulating preparations on the spring wheat yield: humates and obtained by explosive autohydrolysis from vegetable raw materials (pine needles, oat chaff, sunflower husks, high-moor peat). The experiment was carried out in the Ob region forest-steppe conditions. It is shown that the highest yields are formed when seeds are treated with the preparations based on pine needles and Lignohumate. The coefficient of variability of the attribute “Yield” over the years did not exceed 10%, which shows the stability of it formation by the experimental variants.
