The article presents the results of studying the effect of foliar top dressing of meadow clover tetraploid variety Kudesnik with liquid organomineral fertilizer "Agromax Boron-Molybdenum 4%" produced by Kuban Agro-Resource LLC at a dose of 1 l/ha, bioorganic preparations Milefungtm "Boron" and "Boron + Molybdenum" produced by AgroBioTech in a dose of 100 ml/ha for structural parameters, biological yield and seed quality. The use of agricultural techniques in the interphase period of «stem extension stage – bud stage» led to a reliable decrease in plant height by 2.7–14.3 cm (LSD05 = 2.6 cm) or 2.8–14.6% below the control (97.8 cm), an increase in the proportion of generative stem stand by 22.6–76.0 pcs/m2 (LSD05 = 12,4 pcs/m2) or 13.9–46.7% above the control (162.7 pcs/m2), the total number of inflorescences in the herbage by 254.6–297.3 pcs/m2 (LSD05 = 133,0 pcs/m2) or 34.7–40.5% above the control (734.7 pcs/m2), the mass fraction of set seeds in the head structure by 1.76–8.38% above the control (12.63%), which in total increased the biological yield of seeds to 3.35–4.93 c/ha (by 1.6–2.64 c/ha or 46.3–115.3% compared to the control) (2.29 c/ha). A comparative assessment of the effectiveness of the tested preparations made it possible to single out the bioorganic preparation Milefungtm "Boron + Molybdenum", the use of which made it possible to most fully realize the seed productivity potential of the meadow clover variety Kudesnik.
