Influence of Substrate and Fertilization on Growth and Development of Iris adriatica

Iris adriatica is indigenous to Mediterranean part of Croatia. It is an attractive plant and has opportunities for introduction into horticulture and the ornamental plant market. Research was conducted in the experimental garden of the Faculty of Agriculture, University of Zagreb, to assess the possibility of growing this species as a pot plant. Research included 360 potted plants placed as randomized block design experiment. The goal of this research was to determine influence of chosen substrates and fertilizers, as well as to explore growth and development dynamic of the species cultivated outdoors from June till August 2010. The following characteristics were measured: plants height, number of leaves, and number of rosettes. Biometric analysis showed that the development of Iris adriatica was significantly influenced only by substrate, while fertilization and interaction of substrate and fertilization showed no significant impact on examined plants characteristics.
