Abstract
Objective: The objective of this study was to reveal the changes that will occur as a result of different water and nitrogen applications in the drug herb yield, drug leaf yield and essential oil ratios of Tayşi 2002, Ceylan 2002 cultivars belonging to oregano (Origanum onites L.). Material and Methods: In order to meet the objective given above, a study was conducted in Bornova ecological conditions in 2012 and 2013 and the varieties (Tayşi 2002, Ceylan 2002) of the oregano (Origanum onites L.) plants developed in the Department of Field Crops, Faculty of Agriculture were used. Experiments included 4 different (S1,S2,S3,S4) irrigation applications along with the 2 different nitrogen applications 80 kg/ha nitrogen (N80) and nitrogen-free (N0). The data obtained in two years (2012-2013) were then evaluated. Conclusion: As a result, on the study it was found that nitrogen applications alone did not have an effect. It was also determined that the yield values increased with the increase in the amount of irrigation applied, but the essential oil ratios decreased.
