The Effect of Different Doses of Calcium Nitrate Applications on Some Phytonutrient Element Contents of Leafy Parsley (Petroselinum crispum (Mill.)) Plant

Leafy parsley (Petroselinum crispum (Mill)) plant is an important source of Ca for human and 100 grams of leafy parsley plant provides 200-300 grams of Ca. This research was conducted to determine the different doses of calcium nitrate application on some macro and micro phytonutrient element contents of leafy parsley (Petroselinum crispum (Mill)) plant. For this purpose, the experiment followed randomized block experimental design with three replications in greenhouse conditions. 1.5 gm-2 plant seeds sowed for each parcel. Four calcium nitrate application doses (I. dose: 0 ppm, II. dose: 15 ppm, III. dose: 30 ppm and IV. dose: 45 ppm) were applied. Parsley plants were harvested 75 days after of seed sowing. Some macro and micronutrient element (N, P, K, Ca, Mg, S, Fe, Cu, Zn and Mn) contents of plants were analyzed. According to the results, average total N contents of plant samples were determined as 3.93%, 3.96%, 4.01%, and 4.07%, respectively. Other macro elements were determined as follows: P (0.32 %, 0.33 %, 0.35 % and 0.33%), K (5.78%, 5.92%, 6.09% and 6.46%), Ca (0.67%, 0.76%, 0.78% and 0.79%), Mg (0.10%, 0.11%, 0.11% and 0.12%), and S (0.26%, 0.34%, 0.39% and 0.52%), respectively. Nevertheless, for some microelements, the contents were obtained as; Fe (59.06, 62.16, 65.01 and 72.07 mgkg-1) Cu (27.62, 32.03, 38.90 and 39.80 mgkg-1) Mn (24.70, 27.50, 29.03 and 31.87 mgkg-1), and Zn (21.97, 23.30, 29.60 and 57.17 mgkg-1), respectively. The increasing doses of calcium nitrate application resulted in increasing outcomes, which are statistically significant, for each of the nutrient elements.
