Abstract

The objective of this examination was to determine the quality of the seedlings of Pelargonium x hortorum L. H. Bail. Hybrid “Ringo 2000 deep scarlet” by using fertilizers with different Ca (NO3)2 concentration. Easily soluble fertilizers were used as follows: NPK 9-10-34+M.E. + Ca (NO3)2. In all treatments the dosage of NPK 9-10-34+M.E. was the same (1.6 g/l), but the dosages of Ca (NO3)2 were different as follows: 1.6 g/l, 3 g/l and 4.6 g/l. The plants of the control variant were irrigated with plain water. According to the results of all examined biometrical parameters, it was determined that the nutrition with fertilizer NPK 9-10-34+M.E. + Ca (NO3)2 in dosage of 1.6 g/l had the best results compared to the control variant for about 52% more mass of stem, 76% more mass of root, 83% higher number of brunches, 30% higher number of leaves and 15% higher number of inflorescence.
