Abstract
The influence of selected fertilizer within a 6-month period of operation was assessed: Basacote Plus 6M, Osmocote Plus 6M, Plantacote Plus 6M. Plants grown in the substrate without slow-release fertilizer, which were supplied with nutrients only for top dressing, were the control. Two cultivars of the Maxi type of cyclamen were grown in greenhouse in pots during the period from the 25th to the 50th week of the year. While planting the seedlings, 2 g of slow-release fertilizer were added to the substrate directly under the roots. From the third week of cultivation, the plants of each combination were fertilized with top dressing every week. Plant height and diameter, number of leaves, weight of the above-ground part, tuber diameter, earliness of flowering, number of flowers and buds, as well as the content of macro and micronutrients were assessed. The addition of Osmocote 6M or Plantacote 6M into the substrate resulted in plants with a larger fresh weight and larger diameter and earlier flowering with more flowers and buds at the end of the experiment than with Basacote 6M or with only top dressing. The applied slow-release fertilizers had an effect on the content of K, Ca, and Fe in the leaves of Persian cyclamen. The cultivar ‘Rainier White F1’ had significantly more leaves, buds, and flowers and a higher content of P, K, Cu, Zn, and Mn than the cultivar ‘Halios Pure White Compact F1’.

Three fertilizers with a six-month nutrient-release period, which were applied into the substrate during planting: Basacote Plus 6M (16-8-12), Osmocote Plus 6M (15-10-12), Plantacote Plus 6M (14-9-15) (Tables 1 and 2); two cyclamen cultivars of the Maxi type: ‘Halios Pure White Compact F1’ and ‘Rainier
The research showed that the height and the number of leaves of Persian cyclamens did not depend on the slow-release fertilizer (Table 3)
Summary
Accepted: 24 October 2021For many years, the Persian cyclamen has been one of the most popular plants grown in pots for interior decoration. As Persian cyclamens are cultivated in a limited volume of substrate, its type [14,15,16,17,18,19] and the size of the pot [5,20,21]. May determine the growth and flowering of these plants. The growth of cyclamens is influenced by the proportion of individual components [22,23] in a fertilizer, the method of their supply (into the substrate in basic fertilization when planting plants), by fertigation [8,15,23,24] or by foliar treatment [25], and the type of fertilizer [1,2,26,27].
