anglais. In course of the research there was studied the dependence of yield and quality of roots and rhizomes of Valeriana officinalis from the use of micronutrients, entered at different dates by foliar application. The field experiments were realized in the conditions of the Republic of Belarus in 2011-2012 in the Grodno region on sod-podzolic sandy loam soil. As a result of realized research there were revealed that For obtaining the maximum productivity of roots and rhizomes of common valerian (46.4 c/ha) and the biggest quantity of extractive substances from the unit of area (13.1 c/ha) it was 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. It was recommended to bring 3 microelements -B100Cu100Zn100 in chelate forms with every additional fertilizing.

Для получения максимальной урожайности корней и корневищ валерианы лекарственной (46,4 ц/га) и наибольшего сбора экстрактивных веществ с единицы площади (13,1 ц/га) необходимо проводить некорневые подкормки микроэлементами в 3 срока: в 3 декаде июня, в 3 декаде июля и в 3 декаде августа. В каждую подкормку рекомендуется вносить 3 микроэлемента – B100Cu100Zn100 в хелатных формах.
