Abstract

Mahsa Daryadar *

Sweet basil’s raw material grown in the experimental modules of the newest water-stream hydroponics (cylindrical, gully, continuous) and in classical hydroponics exceeds soil culture with dry weight 2.3-4.8 times. The more intensive synthesis of essential oil is observed during the first cut (July) in cylindrical and classical hydroponics and partially in continuous hydroponics and during the second cut (August) in conditions of gully hydroponics and soil culture. Simultaneously during vegetation the maximal output of essential oil (1.3-6.4 times) was provided in cylindrical hydroponics system. High content of the essential oil’s most important ingredient methyl chavicol (43%) is observed in cylindrical hydroponics system during July and August cut.
