Abstract

In order to study the different levels of Nitrogen and different Nitrate: Ammonium ratios in saline and non-saline conditions on the content of chlorophyll, the amount of nutrients and essential oil of denaii thyme, a factorial experiment was conducted in a randomized complete block design with 30 treatments and 3 replications. Nitrogen in three levels (5, 10 and 15 mM), Nitrate: Ammonium ratios in five levels (100: 0, 75: 25, 50: 50, 25: 75, 0: 100) and Salinity in two levels (0 and 50 mM Sodium Chloride) were treated. Results showed that the concentration of nutrients, chlorophyll content and essential oil yield were increased by increasing in Nitrogen amount. In terms of different Nitrate: Ammonium ratios, the concentration of potassium, sodium and chlorophyll content in plant were increased by increasing Nitrate ratio, whereas the concentration of Nitrogen, phosphorus, iron, copper and zinc in plant tissues were increased by increasing Ammonium ratio. Salinity reduced the concentration of nutrients, chlorophyll content and essential oil percentage and increased sodium concentration in plant tissues. The highest percentage and yield of essential oil were obtained from the 75: 25 ratio in non-saline conditions and from 50: 50 ratio in saline conditions.
