Sažetak
The aim of this study was to determine the influence of Rivergreen® on the growth and development of lettuce and endive in controlled conditions. Rivergreen® is a product obtained by milling and tribomechanical activation of river rocks originating from the river Drava. The research was conducted in a Laboratory for vegetables, floriculture and medicinal herbs at the Faculty of Agrobiotechnical Sciences Osijek. Two cultivars of lettuce (‘Majska kraljica’ and ‘Ljubljanska ledenka’) and two cultivars of endive (‘Eskariol žuta’ and ‘Eskariol zelena’) were used. The lettuce and endive seeds were sown in the polystyrene containers filled with substrate which was either conditioned with Rivergreen® or not. Also, Rivergreen® was applied by watering the transplants with an aqueous solution at a concentration of 0.30%. The experiment was set up as a mono-factorial by a split-plot scheme in 5 repetitions per variant. After data processing, statistically significant influence of Rivergreen® treatment on the transplants growth and development of lettuce and endive was observed. In some investigated cultivars significant increase in aboveground fresh and dry weight was recorded. There was also a significant increase in the number and width of leaves while the treatment did not significantly affect the leaf length in none of the investigated species and varieties in this study. Finally, based on the results of this study, it can be concluded that Rivergreen® has a positive effect on the growth and development of lettuce and endive transplants, but the plant response to Rivergreen® application depends on specie and cultivar grown.
