The present study is a compilation of results obtained at the Vegetable Research and Development Station Bacau regarding the influence of the culture system on the quantitative and qualitative yield of tomatoes. The present study provides comparative information regarding yield achievements of tomato genotypes cultivated in two different culture systems (conventional and organic), in order to highlight the suitability of the cultivation system. The best yield results were obtained at a density of 30,000 plants per hectare in both culture systems. All studied genotypes resulted in quantitatively superior yield in the conventional system as opposed to the organic system. Another purpose of this study was to determine the difference in antioxidant activity of tomato genotypes cultivated in the ecological and the conventional culture systems. The results indicate the suitability of the tomato to organic cultivation, highlighting the potential of the tomato species to be utilized as a significant source of natural antioxidants, and also the influence of cultivation systems on the accumulation of antioxidant compounds.
