The Mo- narda didyma L. and Monarda fistulosa L. species were first imported to Ukraine from Europe and America in the middle of the twentieth century, and today they are successfully cultivated as decorative, spicy-aromatic and me- dicinal plants. The purpose of this study was to determine the morphobiological features, valuable economic and selective traits of Monarda didyma, Monarda fistulosa andMonarda × hybrida hort., developed for the arid condi- tions of the southern steppe of Ukraine at the Institute of Rice of the NAAS. The experimental part of the study was performed in 2016–2018 on southern sandy and medium loam black soils (chernozem) in the state enterprise (SE) “Research farm “Novokakhovske”. The experiment was conducted using field, laboratory, mathematical and statistical methods in accordance with the generally accepted methods and guidelines in Ukraine. The plants of de- veloped varieties undergo a full cycle of development under arid conditions of the southern steppe of Ukraine and are characterised by an increased decorativeness, goodeconomic value, high drought and winter tolerance as well as the resistance to pest damage. Yield, mass fraction and content of essential oil in the aboveground mass of plants were determined. Maximal plant height (120 cm), yield of aboveground mass (18 t/ha), concentration of essential oil (0.8% of crude mass) and thymol content (78.3%) are typical of the variety of Monarda fistulosa, Premiera. The variety of Monarda fistulosa, Fortuna, and variety of Monarda × hybrida hort., Tonya, were inferior to Premiera in all of the above-mentioned indicators but demonstrated increased decorativeness and greater resistance to the fungi causing powdery mildew (Erysiphe monardae, Golovinomyces biocellatus). Therefore, they can be recommended for region-wide cultivation in the agricultural enterprises of the southern steppe of Ukraine as promising essential oil, spice-aromatic and decorative crops. The yield of essential oil from raw materials of Monarda didyma variety, Nizhnist, was lower by 32.9% and 26.8%, while its concentration was lower by 37.5% and 28.6%, compared to the Monarda fistulosa varieties Premiera and Fortuna, respectively.

For comparison, the total arable area of cally synthesized oils, is rich in natural aromatic essential oil plants in Ukraine was 18.5 thousand compounds, organic acids, phenols, alcohols, hectares in 2013 but decreased nearly 4 times, to aldehydes and more. This renders essential oils 4.9 thousand hectares, in 2018 [Statistical bulle- expensive on the world market and underscores tins 2010–2018]. Thus, the current agro-industrial 99 Journal of Ecological Engineering Vol. 21(8), 2020 complex of Ukraine is facing two challenges: the activity of essential oil, rendering it unusable in introduction of valuable essential oil crops in the perfume and cosmetic industries [Mastelic et other regions of the country, since it is known al. 2008, Mehdi et al. 2011].
