Abstract:
Valerian (Valeriana officinalis Valeriana officinalis L.) is a prospective medicinal crop for Ukraine with stable high demand on the national and global phytopharmacological market There is a need in the improvement of the crop’s cultivation technology in order to obtain higher yields
of qualitative roots to satisfy the needs of pharmaceutical branch. The prospective way of cultivation technology improvement is in
engagement of modern modeling techniques including multiple linear regression analysis of effects of different agrotechnological
factors on valerian productivity. The study revealed that in Ukraine valerian’s reaction on different mineral fertilizers differ. The yield
of roots depends mainly on Potassium fertilizer rates, the least effect on the crop productivity was fixed for Phosphorus. The model
for valerian root yields depending on NPK fertilization provides new possibilities for planning and prediction of the crop yields based
on the rates of mineral fertilization.
