Abstract

The research objective is to identify the manifestation features of the productivity potential of Salvia officinalis L. in the conditions of the Crimea Foothills. The study was carried out in 2017-2019 on the Kubanets variety (selection of All-Russian Scientific Research Institute of Medicinal and Aromatic Plants) and the population of the Institute of Essential Oil and Medicinal Plants (IELR) in the scientific crop rotation of the Research Institute of Agriculture of Crimea (Belogorsky district). The analysis of samples for a complex of features was performed according to the method, including statistical data processing. The yield of the green mass of the Kubanets variety and the IELR population was, on average, 24.2±1.6 and 26.5±2.1 t/ha, the crop of essential oil was 29.5±3.7 and 34.2±4.2 kg/ha, respectively. In the conditions of extreme drought and high temperature conditions in 2018, the advantage of the IELR population in terms of raw materials content and essential oil collection was revealed, which indicates that it is more adapted to the conditions of the region. When air-dry raw material without stems stored for up to 12 months, the content of essential oil does not decrease and is 1.00-1.10% in the Kubanets variety and 1.05-1.15% in the IELR population. The component composition of the essential oil samples meets the requirements of ISO 9909:1997.
