Abstract

 For assessment of NITROGEN, PHOSPHORUS, POTASSIUM, CALCIUM and MAGNESIUM uptake inMatricaria chamomilla L. under different irrigation regimes a factorial experiment carried out based on randomized complete block design with four levels of irrigation regimes (100, 85, 70 and 55 % of field capacity) with five replications at the experimental greenhouse of Faculty of Agriculture of Urmia University. Results showed that irrigation regimes did not have any significant effect on the percentage of leaf NITROGEN and POTASSIUM.However, the percentage of leaf PHOSPHORUS, CALCIUM and MAGNESIUM were significantly affected by irrigation regimes. The maximum percentage of leaf PHOSPHORUS (0.60 %) was obtained at 100% field capacity, consequently decreased by increasing WATER STRESS, but non-significant difference between was observed in 70 and 55 % field capacity. The minimum percentage of leaf CALCIUM (1.06 %) was obtained at 100% field capacity, although there was no significant difference between other irrigation regimes. The maximum percentage of leaf MAGNESIUM (0.73 %) was obtained at 70% field capacity, and any changes in water supply led to reduction its percentage. The minimum percentage of leaf MAGNESIUM was recorded at 55% field capacity.
