ارزیابی عملکرد کمی، عملکرد اسانس و محتوای عناصر غذایی آویشن در پاسخ به منابع کودی و رژیم های مختلف آبیاری

One of the most important goals of cultivating medicinal plants is to improve their essential oil content, which will be affected by environmental factors such as water deficit stress and nutritional stress conditions. In this regard, a three-year split plot study has been done as a randomized complete block design with three replications in Urmia University at the ۲۰۱۴-۲۰۱۷ cropping years. The main factors include irrigation regimes in three levels (normal irrigation, supplementary irrigation, and rainfed conditions), and the sub-factor at six levels include fertilizer resources {biofertilizer (Azotobaror ۱ + Phosphate-Barvar ۲), complete chemical fertilizer and complete Nano fertilizer with and without vermicompost. Sampling and analysis of traits are performed in the cropping year ۲۰۱۶-۲۰۱۷ (third year of planting). Compared to normal irrigation, the results show that supplementary irrigation and rainfed treatments while reducing the concentration of nitrogen (۱۴.۹۴% and ۷.۷۲%), phosphorus (۳۱.۲۰% and ۳۷.۷۱%), potassium (۱۱.۵۸% and ۹.۱۴%), copper (۱۴.۲۷% and ۲۸.۹۶%), and total dry weight (۳۳.۲۲% and ۵۶.۱۴%), increase the concentration of iron (۸.۰۸% and ۶۶.۰۵%), zinc (۱۶.۸۲% and ۷.۱۶%), and essential oil yield (۲۵.۳۲% and ۳۷.۱۱%) of thyme, respectively. Combined application of nano fertilizer with vermicompost under normal irrigation conditions, and application of nano fertilizer in supplementary and rainfed irrigation conditions has improved essential oil yield by ۲.۷%, ۳.۳۹%, and ۳.۷۸%, respectively. In general, the improvement of essential oil yield in water deficit stress, during the application of nano fertilizer, indicates the efficiency of this fertilizer in providing nutrients and achieving sustainable agricultural goals.
