FODDER PRODUCTIVITY OF HERBS BASED ON UPRIGHT BROME WITH THE APPLICATION OF GROWTH STIMULATORS WHEN HARVESTING FOR FORAGE

Abstract

The article presents data on the productivity of grass mixtures with smooth and upright brome, as well as with garden burnet when using stimulants Growth Matrix and Gumi-20M. The studied mixtures also included sand sainfoin, bastard alfalfa, and bird's-foot trefoil. The study covers fruiting stage, during which the yield and chemical composition were monitored (the content of protein, fat, fiber, ash and carotene was recorded), as well as an analysis of fodder merits was carried out (such parameters as the collection of digestible protein and metabolic energy were assessed), the proportion of components in mixtures and the nature of shoots at the beginning of the regrowth of grasses in spring. Four-component grass stands with sand sainfoin and bastard alfalfa showed maximum productivity. The growth of the indicator, as the legume component was added to the mixture, was not always manifested. The best yield indicators, as a rule, were recorded in variants where the crops were treated and in mixtures with the legume component. Studies have shown that in the herbage, the grass component prevailed over legumes. The smallest proportion of the component was formed by bird's-foot trefoil and garden burnet. The dependence of the percentage of the components on the treatment variant was not revealed.
