Permanent damage to the environment, has led a broad social and political movement to combat this phenomenon which is due among other excesses occurred in the agricultural system also to applied chemical treatments. Due to importance of environment protection and also market request for qualitative products, researchers from over the world try to find solutions in these directions. Tomato is one of the most valuable fruit vegetable grown in conventional and in organic system, in open field and also in protected area. The present study provides information on yield achievements of six tomatoes genotypes cultivated in two different systems culture (conventional and organic) at three densities, in order to highlight the suitability to cultivation system. The best yield results were obtained at density of 30000 plants per hectare in both system cultures. All studied genotypes obtained quantitative superior yield in conventional system comparing organic system. Despite the better results from conventional system, the organic system was more profitable.
