The current state of the essential oil industry in Ukraine requires the expansion of areas
for essential oil crops. Nowadays, the demand for natural vegetable raw materials and lavender
essential oil is growing. Therefore, the aim of the research was to study the morpho-biological
features and productivity of lavender plants by treatment with plant growth regulators Radostim
and Stimpo during the third-fifth years of the growing season in the Southern Steppe of Ukraine.
The research was conducted during 2018–2020. The material for the research work was lavender
plants such as Lavandula angustifolia Mill., the varieties of Sinieva and Vdala. The field
experiment was done with the method of split randomized blocks. The research was accompanied
by phenological, biometric, structural and laboratory observations in accordance with generally
accepted methods. Treatment with the growth regulator Stimpo has the greatest stimulating effect
on the processes of growth and productivity in lavender plants. Using this method, the highest
yield was formed in all years of vegetation from 6.70 to 7.90 t ha-1 at standard humidity, which
is by 14.8–21.1% more than in the control. The mass fraction of essential oil in vegetable raw
materials is quite high (1.85–2.32%), it differs in lavender varieties and does not depend on
treatment with plant growth regulators. The largest harvest of essential oil in all years of
vegetation was obtained by treating plants with the growth regulator Stimpo from 137.30 up to
147.36 kg ha-1
, which is by 15.9–16.7% more than in the control.
