In view of the common practice in Serbia to use peat as a substrate, the objective of this study was to examine the quality of tomato transplants as affected by the addition of certain mineral zeolite-based components. The trials were conducted in a transplant production greenhouse at Trbušani, Čačak (Serbia) using containers as a transplant production method. Main organic substrates used in the trial included peat and forest soil, with the addition of pure and improved zeolite, at different volumetric ratios. The examined parameters comprised the following: plant height, number of permanent leaves per plant, root length, and plant weight. The research results showed significant differences in the above quality parameters, suggesting that the lowest quality of transplants was produced on forest soil as opposed to the transplant cultivation on the peat-improved zeolite mixture being the most effective.
