Abstract

The most effective level of application of organic and mineral fertilizers (60 t/he of manure + N120P80K160) ensures the formation of optimal indicators of the production process of valerian plants (biological mass, leaf surface area, chlorophyll content) causes the formation of the maximum yield of roots and rhizomes within 38,8– 61,6 c/he, the increase in the extractivity of raw materials in 1,21–1,46 times more than the standard, the increase in ash content and the amount of nitrates does not exceed the maximum permissible parameters.
