“…Rate and composition of the essential oil the effect of nitrogen application on the rate of essential oil has been investigated for different medicinal plants. higher amounts of nitrogen lead to a decrease of the essential oil rate of Origanum vulgare L. (3), whereas no variation was detected in Artemisia annual l. (27) and Artemisia absinthium l. (20).…”

“…Accordingly, a decrease in the amounts of total nitrogen, amino acids, chlorophyll and carotenoids is reported for the nitrogen deficient-plants of Achillea collina Becker ex Rchb., whereas the amount of phenolics and antioxidant capacity are higher in leaves and roots (14,15). Furthermore, improved nitrogen nutrition leads to higher values for leaf size, number of flowering stalks (27), fresh and dry weight of shoots (15,25).…”

Artemisia dracunculus L. (tarragon), known as "tarkhun" in Iran, is a perennial herb in the Asteraceae family, which has a long history of use in culinary traditions. A factorial experiment based on the Randomized Completely Block Design with three replications was used. The treatments were performed at four level of foliar applications of Ca(NO 3 ) 2 and KNO 3 fertilizers (including control (sprayed with water), 1.5, 3 and 6 gl -1 ). This experiment was conducted at field conditions in a farm in "Ray" in 2010. The results showed that Ca(NO 3 ) 2 application significantly increased plant height, fresh and dry matter yield by an average of 10.1, 35.8 and 33.5%, respectively. Essential oil content was not significantly affected with Ca(NO 3 ) 2 fertilization. Nevertheless, Ca(NO 3 ) 2 application increased essential oil content by an average of 64.4% compared with the control. Ca (NO 3 ) 2 foliar application increased N and Ca content of leaf tissues. The concentrations of P, K, Mg, Fe, Mn, Zn and Cu significantly affected by Ca(NO 3 ) 2 levels. Plant height, fresh and dry matter yield, essential oil content and yield significantly increased with KNO 3 foliar application by an average of 4.4, 60.5, 50.4, 42.5 and 119.6%, respectively compared with the control. The KNO 3 application significantly increased N, K, Fe, Mn and Zn concentrations compared with the control. Also, leaf P, Ca, Mg and Cu contents were influenced by KNO 3 fertilization. The interaction between Ca(NO 3 ) 2 and KNO 3 treatments was significant in leaf N, K, Mg, Fe, Mn, Zn and Cu contents.

“…This element (K) is involved in the growth of meristematic tissue and is indispensable for the maintenance of cell turgor pressure, which is required for cell expansion (Rogalski, 1994;Özgüven et al, 2008). The use of K is especially important when high yield is expected (Defan et al, 1999).…”

This experiment was designed to evaluate the effects of organic (liquid humic acid) and inorganic (potassium sulphate) on phytochemical and morphological attributes of St. John's Wort (Hypericum perforatum). Thus, a research was conducted in a factorial experiment (3×3) based on completely randomized design with three replications. Treatments consisted of potassium sulphate (Kx) at three concentrations (0, 60 and 100 Kg. ) which were fertigated four times of 15-days intervals. Results showed that the plant stem height, number of flowering stems and number of flowers were significantly affected by simple effect of each fertilizers (p<0.01), while their interaction effect was not significant for the plants height. The highest contents of fresh and dry weight were achieved under the highest amounts of fertilizers (K100 and H40). The highest stem height, number of flowers and number of flowering stems also belonged to these treatments. Increment of applied fertilizers led to increase of obtained essential oils, so that application of these fertilizers simultaneously increased the essential oil content up to 6-fold. Regarding the antioxidant activity, applied fertilizers at their high levels showed significant effects on decrease of EC50, which means the increment of antioxidant activity of H. perforatum.
