The cultivation of ornamental plants and cut flowers is widespread in the economies of the whole world. Every year, new methods of production are introduced that enable the increase of the market and instigate human interest in various plant species. The cultivation of calla, of the species Zantedeschia aethiopica, is not common and widespread in such a system, and this thesis is designed in order to establish whether it can be realized. This research took place on an experimental agricultural experiment site owned by the Secondary school Bedekovčina, more precisely in a greenhouse with the possibility of hydroponic cultivation. 67 plants were used for this experiment. Of these, 31 plants were placed in the substrate in containers with a diameter of 20 cm, and 36 in the hydroponic system, which were rooted in rock wool through containers with a 15 cm diameter. They were watered with the same nutrient solution throughout the entire period of the experiment from 9th March until 12th June. The results show oscillations in the size of the leaf mass and occurrences of leaf yellowing in both systems, but in different time periods. Due to the larger space for root growth, calla in hydroponics eventually showed better generative and vegetative growth.
