Abstract

For obtaining the maximum productivity of roots and rhizomes of common valerian (46,4 centners/hectare) and the biggest quantity of extractive substances from the unit of area (13, 1 centners/hectare) it is necessary to carry out not root additional fertilizing by microelements in 3 terms, in the third decade of June, in the third decade of July and in the third decade of August.
