MAIN DIRECTIONS AND RESULTS OF RESEARCH ON PERENNIAL GRASSES IN FIELD FODDER PRODUCTION

The main directions of research on perennial grasses in the field feed production Feed Institute are revealed. analysis was carried out grasses: clover, alfalfa, galega and grasses. In chronological order, indicating names positions researchers, a list all areas on: introduction culture is given; terms, methods sowing, norms sowing seeds single-species mixed phytocenoses; selection cover crops; effective use phosphorus, potassium nitrogen fertilizers trace elements, depending composition grass stands different years use; assessment fungicidal role molybdenum mineral fertilizers; adaptive components order to create an uninterrupted green raw material conveyor; modes that provide energy-saturated, high-protein feeds; determination size symbiotic fixation atmospheric nitrogen, varietal characteristics growing conditions; herbicides protect crops from weedy vegetation, comparative productive longevity, etc.
