The Determination of Seed Yield, Slymarine and Components of Essential Oil of Milk Thistle (Silybum marianum) Cultivated in Konya Ecological Conditions

This research (2008) has been conducted in Medicinal - Aromatic Plants laboratory and Medicinal and Aromatic plants Experimental Farm of Field Crops Department, Agriculture Faculty, Selcuk University to determine the effect on yıeld and quality some characters of organic fertilizers applied at the different doses on milk thistle (S. marianum) grown under Konya ecolojical conditions. Experiment was designed in randomized complete plot the divided parcels design with three replications. It were applied at the three different doses sheep manure as organic fertilizer (0, 500, ve 1500kg/da). In this study; plant height, branch number, seed yield, rate of crude oil yield, composition of oil and flavonoid (silymarine) were examined. According to results of this research; plant height, branch number, seed yield, rate of crude oil yield, composition of oil and flavonoid (silymarine) varied between 75.73 - 118.66 cm, 5.06 - 21.33 pieces/per plant, 72.26 - 148,73 kg/da, % 20.2 - 27.7 and % 1.1 – 3.1, respectively. According to the results of this research; high silymarine yield, crude oil yield, fatty acid composition and drug of Milk thistle (S. marianum) cultivated in Konya ecological conditions were obtained from 1500 kg/da applied organic fertilizer and population of Konya.
