Abstract :
Biological and chemical fertilizers have important effectiveness in growth and development of plants and consumption of this fertilizers made increasing in quantitative and qualitative production in plants. In this study, the effects of biological fertilizers such as Botamisol (A), Humic acid (B), horse manure (C), sheep manure (D), cow manure (E), poultry manure (F), vermicompost (G) and complete chemical NPK (H) with two control (water foliar application (I), and without any foliar application (J)) and three levels of drought stress (K1, K2 and K3: Field Capacity, 50% and 75% loss of gravitational water respectively on morpho-physiological characters and content/composition of essential oil of Salvia syriaca L. were investigated. This research was performed in randomized complete block design in factorial layout with 3 replication. From fifteen essential oil components, the most components were 1, 8 cineole, cis-thujone, trans- thujone, camphor (oxygenated monoterpenoides). Cis-thujone (30.3-29.5 %) had the most amount in essential oil components. Treatments of HK1, FK1 and GK1 made the most height of plant (48.8-49.4 cm), number of stem (20.1-19.5), total chlorophyll (2.42-2.55mg.g FW-1), RWC (69.2-67.8) and content of essential oil (1.4-1.55%). Compositions of sesquiterpene hydrocarbons such as caryophyllene, alpha humulene and manool increased in drought stress. Suggest to obtain the most quality of essential oil in Salvia such as important components (cis-thujone and camphor) in same condition, use the poultry manure and complete chemical fertilizers.
