The Effect of Biological and Chemical Fertilizer on Quantity And Quality of Essential oil Of Satureja hortensis in Khuzestan Provience

Satureja hortensis is one of valuable and aromatic medicinal plant whose essential oil is widely used in different industries. Investigation by using the different treatments of nitroxin biofertilizer combined with chemical fertilizer urea on percentage and compostion of essential oil of savory was conducted based randomized complete block design with three replication. Analysis variance of data showed that the percentage and yield of essential oil were significantly affected by experimental treatments. The highest essential oil percentage (۱.۹۷%) and yield was in plants grown on ۱۰۰% biofertilizer seed treatment in comparision with control. The highest of main components were carvacrol, γ- terpenin, α- terpenin, p- cymen in all treatments. Combination of chemical and biological fertilizer by irrigation method increased the main effective compounds such as, α- terpenin and γ- terpenin with compared to other measured treatments. The highest content of carvacrol (۵۳.۵۷%) was in chemical fertilizer treatment while lowest content of γ-terpenin (۳۴.۵۲%) in control. The amount of hydrocarbon containing monoterpenes of essential oil increased in ۱۰۰% biofertilizer seed treatment and ۵۰% chemical fertilizer+ ۵۰% biofertilizer seed treatment in comparision with samples of control and without the use of bio fertilizer. Result of this study showed that the use of biofertilizer alone or combined with chemical fertilzer have a positive effects on content of essential oil percentage and effective composition of satureja hortensis.Our result are consistent with the studies of other scientists
