Abstract
We investigated the growth of tomatoes, radishes, sunny lettuce, Eustoma and gerbera in a medium containing granules made by crushing used tiles as a soil substitute, with and without chitosan.
There was no remarkable difference between control and the medium containing the used tile granules in the growth of tomatoes, Eustoma and gerbera. However, the growth of radishes and sunny lettuce was decreased compared to that of controls. When used tiles and 1% chitosan were mixed to form a culture medium, the growth of all the investigated vegetables and flowers was better than that of the controls.
Thus with tomatoes, Eustoma and gerbera it is possible to employ granules from crushed used tile as a substitute for a sandy loam soil medium. After application of 1% chitosan culture medium, the growth of all crops was better than that of the control plants.
