Abstract
A greenhouse experiment was conducted to evaluate the effects of nitrogen source and level on growth characteristics, volatile oil percentage and oil yield of garden thyme in Shahin Shahr, Isfahan province, Iran. The pots were treated using 50 or 100 mg N/kg (100 or 200 kg N/ha) by two sources of nitrogen, ammonium nitrate (33% N) and urea (46% N), and compared to control (without using nitrogen). The experiment was carried out using a Completely Randomized Design (CRD) with three replications. The results indicated that the source and level of nitrogen fertilizer altered growth characteristics, oil percentage and oil yield of garden thyme significantly. The highest value of shoot dry weight (15.04 g/plant) was obtained at 100 mg N/kg of ammonium nitrate which was significantly different when compared to other treatments. The maximum of volatile oil percentage (0.80%) was obtained at 100 mg N/kg of ammonium nitrate which was not significantly different when compared to 50 mg N/kg of ammonium nitrate. The highest value of volatile oil yield (120.26 mg/plant) was achieved on 100 mg N/kg of ammonium nitrate which was significantly different when compared to other treatments.
