Calendula officinalis L. from the Compositae family as an important ornamental and medicinal plant used in landscape design and homeopathic methods [1]. This investigation is planned for the desirable effect of bio-stimulants foliar application on phytochemical traits of plants. The experiment with randomized complete blocks design was conducted in 10 treatments with 3 replicates. Experimental treatments included bio-stimulants with commercial formulations of Aminolforte, Kadostim, Fosnutren, Humiforte (0.75 and 1.5 L.ha-1) and chemical fertilizer N, P, K (70 kg.ha-1 before sowing) and control treatment (without foliar application). Results showed that the effect of these treatments was significant (P < 0.01) on phytoochemical traits. The highest amount of total carbohydrates in leaves (0.244 mg.g -1 DW) was observed in Kadostim 1.5 L.ha-1. The content of macroelements of N, P, K and micronutrients of Fe, Zn, Cu, Mn and Ca increased with foliar application of bioactive amino acid compounds. In general, Fosnutren, Aminolforte and Kadostim 1.5 L.ha-1 were the best treatments for phytochemical characters which can be due to existence of amino acid compounds and macro-nutrients such as nitrogen, phosphorous and potassium in their formulations.
