Yield and content of essential oils in the common origanum nursery

Abstract

Common origanum is one of the most famous spices, it is popular all over the world. The purpose of this work is to conduct a comparative assessment of the yield of raw plant materials and the content of essential oils in common origanum plants. Field research was carried out in 2019-2020 at the experimental field of the Northern Trans Urals Research Institute - a branch of the Tyumen Research Center SB RAS (Moskovsky settlement of the Tyumen district). The soil of the experimental site belongs to the subtype of dark gray forest, heavy loamy according to the granulometric composition. From the studied 350 common origanum samples, 16 samples were isolated. All samples were evaluated according to the following criteria: the yield of raw plant materials and the amount of essential oil. The Khutoryanka variety is accepted as the standard. For two years of research, three samples were distinguished from the studied samples of common origanum in terms of the yield of raw plant materials compared to the standard: 12-2-2; 13-2-1; 15-2-1, the yield of these numbers was from 3.6 to 3.9 t/ha, this is (13.3, 10.0, 6.6 %) higher than the standard. From the studied samples of common origanum, two samples were distinguished by the content of essential oils in dry plant materials - 14-2-3 and 21-1-1. The harvest per hectare of these samples was, respectively, 750 and 928 ml in 2019, and in 2020, 1026 and 1120 ml/ha.
