    Determination of effect of plant density on oil content and composition for milk thistle (Silybum Marianum L. Gaertn.)
    (2017) Arslan, Yusuf; Katar, Duran; Subaşı, İlhan; Katar, Nimet
    The study has been carried out in Field Crops Central Research Institute, Ankara in 2010 and 2011 years for the purpose of determining the impact of different plant densities on the oil content and oil composition of the milk thistle (Silybum marianum L. Gaertn.) plant. In the experiment,a randomized complete block design with three replications were used. The seeds of milk thistle were obtained from Department of Field Crops, Faculty of Agriculture, University of Ankara. The results showed that the densities of plant and growing years didn’t have a significant effect on the oil contents. On the other hand; the years had a significant effect on the fatty acids profile, except for palmitic acid, but it showed that the densities of plant had no effect on the profile of the fatty acids

    Effect of ontogenetic and diurnal variabilities on yield and quality characteristics of summer savory (satureja hortensis l.)
    (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2021) Katar, Nimet; Katar, Duran; Subaşı, Ilhan
    This study was carried out to determine the effects of different harvest times (ontogenetic and diurnal variability) on the yield characteristics, content and composition of essential oil in summer savory (Satureja hortensis L.) in 2014 and 2015. The experiments were conducted at the experimental fields of the department of field crops, Faculty of Agriculture, Eskisehir Osmangazi University using a split-plot randomized complete block design with three replications. According to this research results, values of dry herb yield, dry leaf yield, essential oil content and essential oil yield ranged from 2.11-3.26 t ha(-1), 2.07-2.79 t ha(-1), 2, 55-3, 73% and 56.89-93.57 1 ha(-1), respectively. Carvacrol, the first main component of the essential oil, ranged from 49.71 to 54.75%, while gamma-terpinene, the second main component, changed from 28,03 to 34.58%, Considering the dry leaf, essential oil yield, content and components, the harvest in 40-60% flowering period and at 12:00 pm for the cultivation of summer savory in EskiKhir ecological conditions can be suggested.
