A field experiment on an Arenic Fluvisol WRBSR, 2006 with a three different type of tomato plants - Prekos F1, Bakini and Pink Charm is made. The influence of specific nitrogen norm 30 kg N da-1 in form of mineral and organic compost, on a PK-basis over quality characteristics of the production from the chosen variety was traced. The experiment proof that in the most cases the fruits of organic compost plants were richer on absolute dry matter compare to these from plants treated with fertilizer. The higher quantity of dry matter after the first analyse was found in variety Pink Charm treated with organic compost - 6.8%, and after the second analyse in the analogical experiment with variety Bakini - 7.74%. The fruits from the plants treated with organic compost are in general larger, with higher vitamin C quantity and mutual sugar compare to those treated with fertilizer. The coefficient of determination R2 from the equilibration describing the dependence of fruit weight and fruit number, and fruit weight and absolute dry matter, mutual sugar, lycopene and carotene are high reliable numbers.
