Among the alternative agricultural systems that have been developed, organic agriculture has deserved increasing interest. This fact is due to the demand of a certain segment of consumers for products with taste, the aspect not being a determining factor for the acquisition. The study aimed to assess whether the application of fertilizers with algae and protein hydrolysate affects the quality of tomato fruits, Siriana cultivar. The applied fertilizers contained substances that are allowed to be used in organic agriculture. The research has been conducted in vegetation pots and quality indicators (chlorophyll pigments, total phenolic content, titratable acidity, soluble solid content, organoleptic characteristics) and production (mean weight per fruit and number of fruits) indicators have been evaluated. The results obtained showed that both organic substances (algae and hydrolyzed proteins) improve the quality of tomato fruits, and production indices were higher by about 5.4% for variant B_AN, respectively by 5.8% for variant B_HP compared to variant control (without organic substances).
