IMPACT OF FOLIAR FERTILIZERS ON SUNFLOWER PRODUCTIVITY IN THE SOUTHERN STEPPE OF UKRAINE

The article is devoted to the results of scientific research on peculiarities productivity formation sunflower hybrids Darius, NK Kamen, Tutti, depending foliar top-dressing micronutrients in soil and climatic conditions Mykolaiv region. There a direct dependence crop growth its optimal combination weather nutrients crops. cover experimental field represented by chernozem southern low-humus dusty-heavy loam brownish-pile forest-like loams. According content mobile elements, characterized an average nitrogen phosphorus very high potassium. In experiment, cultivation techniques were generally accepted for area, except variants studied according scheme. where microfertilizers studied, feeding hybrid plants was performed two-factor experiment during 2020-2021, yield seed quality high-oleic timing studied. are included State Register Plant Varieties Ukraine recommended Steppe zone. study showed that fertilization with affects performance individual productivity, particular when applying Quantum phase 6-8 leaves crops Kamen husk 21.1%, which less than control (without microfertilizers) 0, 8%, weight 1000 seeds 2.6% larger, accordingly diameter basket increased 1.2 cm. effect also different: over years highest formed drug leaves, was: Darius 2.26 t / ha, − 2.55 ha Tutti 2.41 ha; Foliar significantly affected fat, particular, oil obtained – at 13.4 kg more 2.2 smallest use Rostock amounted 10.5 h ha. results, it carry out sowing rotations as best option under condition Kvantum microfertilizer working fluid consumption rate 4 l/ha culture leaves.
