Abstract

Valuable leafy green vegetable kale (Brassica oleracea var. Sabellica L.), also known as a curly cabbage, was first was introduced in Armenia, and its high productivity and productivity were studied and established in water stream hydroponics experimental modules (gully, cylindrical and continuous), classical hydroponics, as well as in soil culture. In kale revived from hydroponical different systems the raw material and the output of pharmaceutical indices (vitamin C, extractive substances, flavonoids and tannins) are higher 1.5 to 1.8 times and 1.2 to 2.3 times, respectively, compared with soil culture. Water stream hydroponics is a safer radio-ecological and biotechnological method for the production of raw material than classical hydroponics and soil culture.

Keywords: Water stream hydroponics, kale, ⁹⁰Sr, ¹³⁷Cs, bio-pharmacochemical analyses.
