The use of modern and safe techniques to increase plant growth and yield is of significance. There is little data, to our knowledge, on the use of organic fertilization and ozonated water (ozone (O3) affecting tomato (Solanum lycopersicum) growth and quality. Different tomato growth and fruit quality parameters including yield, fruit number, leaf fresh and dry weight, leaf and inflorescence number, plant height and stem diameter, distance from the first inflorescence to the collar, total soluble solids, total acidity, chlorophyll a, chlorophyll b, and total were determined. O3 treatment resulted in significant affects in all tomato parameters. One of the interesting results of the present research is the increased concentration of the antioxidant ascorbic acid (vitamin C) in response to ozonation, which can also improve tomato quality. However, organic fertilization and its interaction with the O3 treatment significantly affected only some of the measured tomato parameters. Ozonated water, at proper concentrations, may improve tomato growth and fruit quality, and if combined with organic fertilization, its positive effects may increase.
