The aim of the study is to develop a high–yielding variety of Dracocephalum moldavica L., suitable for cultivation in the Central region of the Russian Federation, and to study the seeding rates and sowing methods on its example. The experimental part of the work was performed in Institute of Medicinal and Aromatic Plants in 2016-2017 by field and laboratory experiments. New variety "Nezhnost" (selection № 14-99) is derived by the method of individual-family selection of the cultivated population, is significantly superior to the zoned variety Gorynych on the yield of dry herb (at LSD05=1,8 с/ha) and seed (at LSD05=0,61 с/ha), gross yield of essential oil to by 20%. The object of the study of varietal features of seeding rates and methods of sowing was a promising variety "Nezhnost", for which two-factor experiment was put: 6 variants of seeding rates and 3 variants of sowing methods. Sowing period: early spring. Harvesting: when browning 3/4 of stems. The biological potential of plants has been fully realized in wide-row crops with seeding rate of 2.0-2.5 million PCs/ha, contributing to the formation of productive architectonics, optimization of the production process and maximum realization of seed productivity. To obtain high yields of Dracocephalum moldavica L. when cultivated on seeds in the Central region, the rate of seeding (2,5 million pieces of germinating seeds per hectare) is reduced by 20% of the rate when sowing on green mass, a wide-row method of sowing is used.
