The study evaluated yield, quality parameters and biological value of the yield of selected leaf parsley cultivars. The investigated material included marketable yield (entire leaves), and chemical analyses of fresh leaves included the determination of dry weight, total acidity, the content of L-ascorbic acid, chlorophyll a and b and total chlorophyll, total carotenoids, total polyphenols and antioxidant activity measured as the inhibition of DPPH radicals. The aim was investigate a few cultivars of leaf parsley, including ones with curly and with plain leaves. The variety with plain leaves called Plain Leaf produced significantly higher yield of 166.52 t ha-1 in 2015 and 97.31 t ha-1 in 2016. The cultivars Gigante d’Italia, Plain Leaf and Lisette achieved the highest percentage share of leaf blades in their yield. The cultivars Lisette and Neapolitan parsley showed the highest content of pigments. A comprehensive analysis identified cv. Neapolitan as the most valuable cultivar – the richest in polyphenols and L-ascorbic acid and with the highest antioxidant activity measured by the inhibition of DPPH radicals. With the mean content of calcium at 40007.5 mg kg-1 DM and magnesium at 3208.25 mg kg-1 DM in 2016, the leaves of cv. Titan were the richest in elements building bones, teeth, skin and hair. The leaves of cv. Plan Leaf contained high levels of sodium, magnesium, copper, iron, cadmium and manganese. The growing conditions, including soil type, fertilization, moisture content and insolation, may have had influence on yield and biological value of parsley leaf.
