Abstract
The data on the study of the influence of the developmental phase of meadow legumes on their symbiotic nitrogen fixation are presented. It has been experimentally proved that the mowing time significantly affects the formation of the symbiotic apparatus and the accumulation of biological nitrogen. Due to symbiotic fixation on medium-acid soils of heavy texture in the first two years of life, Carmine meadow clover cultivated from the beginning of budding phase to the beginning of flowering, about 80–90 kg of nitrogen per 1 ha was accumulated, which corresponds to 57–67% of the total removal with the harvest. Such a symbiotic apparatus provided high protein feed from the main cut for hay without additional mineral nitrogen fertilizers in the range of 4.4–5.4 tons of dry weight or 19.3–22.2.2 tons of green mass per hectare. Later mowing of the grass stand led to a significant reduction in the use of biological nitrogen. The removal of biological nitrogen decreased by 1.8 times and amounted to only 45 kg per 1 ha.
