The effect of different water and nitrogen applications on some yield parameters and antioxidant activity on
sage (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 (irrigated when it’s needed), S2 (20 days dry before harvesting) and S3 (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 (cm), fresh herbage yield (kg ha
−1
), drug herbage yield (kg
ha
−1
), drug leaf yield (kg ha
−1
), essential oil ratio (%), essential oil yield, essential oil content (%), antioxidant
capacity (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.
