Abstract
The Effect Of Nitrogen Fertilizations On The Yield And Quality Of Sage (Salvia Officinalis L.)
This study was conducted to find out the effect of different nitrogen (0,50,100 and 150 kg/ha) fertilizations on drug yields, essential oil content and quality of sage (Salvia officinalis L.). The study was realised at Faculty of Agriculture, University of Gaziosmanpaşa in the experimental areas, in 1998 and 1999.
Experiments was realised on Randomised Split Desing at 3 replications. Row spaces were 40 cm, plant spaces were 25 cm. İt was harvested 2 times in a year.
According to the results, at the increasing nitrogen fertilizations, fresh herba yield, drug herba yield and drug leaf yield increased as regularly and continously. The highest essential oil content was obtained at the first harvesting and 5 kg/da N dose. However, the variation limits of combinations, for plant hight varied from 31.53 to 51.70 cm, for fresh herba yield from 15691,5 to 35982.2 kg/ha, drug herba yield from 3617,2 to 7348.5 kg/ha, drug leaf yield from 2606.2 to 4470.3 kg/ha and essentia] oil content from 0.88 tol.21%.
