Abstract: Purpose. Substantiation of the importance of meadow clover as one of the important legume crops in agriculture, which requires improvement of the biologization of the technology of growing the new Tina variety. Methods. Field, laboratory, visual, measuring, weighing, quantitative, trial sheaf method, mathematical, statistical. Results. Innovative technologies for growing meadow clover seeds of the new high-yielding synthetic variety Tina have been developed by pre-sowing treatment of seeds with bacterial preparations Rhizobofit and Rice P with foliar feeding during the growing season with chelate microfertilizers Ecoline Bean and Ecoline Bor Premium to improve the fixation of atmospheric nitrogen by nodule bacteria and the mobilization of macro- and microelements from the soil against the background of the main fertilizer for the cover crop with mineral and limestone fertilizers. In the conditions of 2022-2025, this ensured the maximum yield of meadow clover seeds of the Tina variety - 479 kg/ha. Of the individual years of research, the most favorable for the formation of seed yield was 2025, in which the yield of meadow clover increased to 518 kg/ha. Conclusions. It was established that when growing meadow clover of the new synthetic variety Tina with high sowing and yield properties, pre-sowing seed treatment with bacterial preparations in combination with the application of chelate-based microfertilizers twice in the budding phase and the beginning of bean formation against the background of the main mineral fertilizer N30P60K60 and fast-acting limestone fertilizer Ca(OH)2 (slaked lime - fluff) - 0.5 norms for hydrolytic acidity, which contributed to an increase in seed productivity on average for 2022-2025 by 129 kg/ha or 36.7% compared to the control without seed treatment and foliar top dressing.
