The application of biostimulants in the technology of cultivation of alfalfa changeable for the Middle Volga region

Theoretically and practically justified the use of growth regulators Mival-agro and Lignohumate in the cultivation of Lucerne varieties “Emerald” on green food. The effect of biostimulants on the growth processes of alfalfa was revealed. The productivity and quality of the green mass of alfalfa in two cuts hay crop studied. It is shown that the correctly selected growth regulators and their doses allow to increase the yield of fodder crop per unit area while improving its quality. Seed treatment and foliar feeding of crops with growth regulators Mival-agro and Lignohumate contributes to the productivity of green mass of alfalfa varieties Emerald and improve its forage qualities. The dynamics of the intensity of the growth of stems in the use of these stimulants. We found that the lack of moisture stimulating effect of the drug Mival agro less pronounced than in a satisfactory moisture supply. Lignohumate also has a pronounced auxin activity. It stimulates the growth processes and, particularly, the synthesis of carotene - provitamin of vitamin A, vitamin growth. Using the studied analogues of natural phytohormones can adjust the timing of the phytophase, optimal for creating a conveyor.
