ELEMENTS OF NUTRITION OF HYSSOP OFFICINALIS ON DRIP IRRIGATION IN THE SOUTH OF UKRAINE

Purpose. The article is devoted to highlighting the results of scientific research conducted during 2020–2021, purpose which was establish influence ecological and agrotechnical growing conditions on productivity medicinal hyssop (Hyssopus officinalis L.) culture under drip irrigation black soil southern Steppe Ukraine, as well development, justification implementation methods their cultivation for region Ukraine. Methods: general (dialectical – observation dynamics growth development culture; method hypotheses scheme research; analysis study object synthesis formation conclusions, recommendations production; abstraction theoretical generalization calculation establishment economic energy efficiency measures) special (field relationship with biotic abiotic factors in specific area; laboratory methods: morphophysiological biometric parameters plants; chemical composition grain soil; physical seed indicators; statistical comparative-calculation technologies. Statistical, were used generalize process experimental data: dispersion, correlation regression analyses. Research results. In arid climate Mykolaiv temperature fluctuations over years, an important direction introducing increasing essential oil crops use nutrition elements. Thus, treatment plantings biologics creates optimal Hyssopus L. most developed plants common recorded background N90P90 phases branching budding Combi Helafite. this variant, largest number stems per plant counted (59 PCs. height 71.4 cm, diameter Bush 66 water consumption a unit yield flower mass lowest (584 m3/t). best option 7.92 t/ha, 95.04 kg/ha, profitability reached 224.3% conditionally net profit 72,304 thousand UAH/ha at cost 1 kg 339 UAH. Conclusions. According research, it recommended production dripirrigated Marquis variety chernozems steppes order increase productivity, quality indicators, mineral fertilizers dose carry out two foliar feedings drug Helafit combi phase culture.
