Abstract

The aim of the article is to define hyssop (Hyssopus officinalis) ‘Markiz’ cultivar capacity parameters aimed at recultivating degraded soils, alkali soils, sloping lands, local landscaping of technologically polluted areas, which will promote improvement of anthropogenically transformed ecosystems. To implement such practical measures comprehensive approach should be used while selecting agronomic measures for growing crops by applying fertilizers (N₆₀P₆₀ broadcast, N₃₀P₃₀ broadcast + N₃₀P₃₀ with irrigation water during boot stage) and retaining soil moister per 30–40 cm depth on the level of 80–70–70% MHC. In these circumstances, stable agrophytocenosis is formed with optimal plants capacity parameters and crops of dry floral materials at the level of 52.6–53.7 c/ha. After the first mowing at the end of June, shoots are growing and flowering during the last August decade and beginning of September. However, phytomass yield is twice lower compared to the first mowing.
