Abstract :The effect of different water and nitrogen applications on some yield parameters and antioxidant activity on sage insert ignore into journalissuearticles values(Salvia officinalis L. var. Extrakta); was investigated. A field trial was arranged in the split plot design with four replications under the Bornova ecological conditions in 2012 and 2013. The following water regimes were used as main plots: S1 insert ignore into journalissuearticles values(irrigated when it’s needed);, S2 insert ignore into journalissuearticles values(20 days dry before harvesting); and S3 insert ignore into journalissuearticles values(40 days dry before harvesting); and nitrogen applications were used as sub-plots such as 0 kg ha-1 and 60 kg ha -1 . The following plant characteristics such as plant height insert ignore into journalissuearticles values(cm);, fresh herbage yield insert ignore into journalissuearticles values(kg ha −1 );, drug herbage yield insert ignore into journalissuearticles values(kg ha −1 );, drug leaf yield insert ignore into journalissuearticles values(kg ha −1 );, essential oil ratio insert ignore into journalissuearticles values(%);, essential oil yield, essential oil content insert ignore into journalissuearticles values(%);, antioxidant capacity insert ignore into journalissuearticles values(μmol FRAPgDM); were recorded. The highest essential oil ratio was obtained from the S3 water dose such as 2.07%. The main component in the essential oils recovered by both experiments were α+β thujone showing a large variation. Considering the N fertilization combined with the S2 irrigation had positive effect on the characteristics measured. It could be concluded that the antioxidant activity tended to increase as the soil moisture decreased.
