Investigation of the effect of a biological product based on humates and trace elements on morphometric indicators and yield data of winter wheat

The article presents the data on the study of a new biological product based on peat humates and trace elements on winter wheat Alekseich. This variety is recommended for cultivation in the Orel, Kursk, Belgorod regions and also in some southern regions. It has high cultivation ability and is responsive to micro fertilizers. Peat humates have a growth stimulating activity and peat humates treatment in critical phases of plant development can provide strong support for the plant during stressful factors as well. The content of trace elements in the biological product makes it possible to compensate for the lack of trace elements and affects the protective, growth and biochemical processes occurring in the plant. It was revealed that leaf treatment with this product during the tillering and earing phase has a positive effect on morphometric indicators and productivity of winter wheat. It is the double treatment of plants in the growing season that gives the maximum result on the productivity of winter wheat. The research took place in the fields of the Research, Educational and Production Centre “Integration” (NOPC "Integration") on dark gray forest soils. The new biological product based on peat humates and trace elements contributes to a greater accumulation of biomass, plant height in the variety “Alekseich”, root length. The mass of the root system under the influence of this new biological product increased by 7.9% compared to the control. The research team established the important fact that the average number of leaves increased by 12.9%, leaf length by 10.3%, leaf width by 9.9%, tillering node by 13.9%, sugars by 5.7%. Such indicators as a tillering coefficient, the density of the stem were found in the increase of the winter wheat yield by 9.5%. It is also associated with the increase in the mass of ears and the number of grains in the ear. The results of the study showed that in treatment with the biological product based on peat humates and trace elements, the weight of 10 ears increases by 4.7%, the average length of the ear by 4.9%, the number of grains in the ear by 5.9%. It finally affected the yield increase by 9.5% compared to the control.
