    Lettuce is an annual, cool season, leafy vegetable crop from Asteraceae family. The aim of this study was to examine the effects of genotype and organic biostimulant on different morphological and production characteristics. Lettuce plants were grown from the seedlings in the open field, at the company Iceberg Salat Centar, from May to June. Two lettuce cultivars were examined (green oak cv. Pleasance- Bejo Zaden and red lollo rosso cv.Orville- Rijk Zwaan). Plants were grown on a density equivalent to 10 plants/m2 with application of regular growing practices. Organic biostimulant based on humic acids (Cytohumat-Agrofarmica) was applied in the soil before transplanting and two times foliar during vegetation period. The analysis of lettuce quality parameters was carried out at the end of the vegetation period, during harvest. The impact of biostimulant was statistically significant in both cultivars, especially in parameters number of leaves per plant and rosette fresh weight. The average number of leaves per plant with applied biostimulant was (43.5 Pleasance and 26.67 Orville). In control treatment this parameter was significantly lower in both cultivars (37.17 and 21.33, respectively). Rosette fresh weight in control and biostimulant treatment in Pleasance was 324.33 and 440 g, and in Orville 132.5 and 229.17g. There wasn’t significant difference between cultivars in rosette diameter but within the same cultivar application of biostimulant significantly affected this parameter. To conclude, we can recommend the usage of organic biostimulant in lettuce production.Π‘Π°Π»Π°Ρ‚Π° јС јСдногодишња врста, ΠΏΡ€ΠΎΡ…Π»Π°Π΄Π½Π΅ ΠΊΠ»ΠΈΠΌΠ΅, која ΠΏΡ€ΠΈΠΏΠ°Π΄Π° Π³Ρ€ΡƒΠΏΠΈ лиснатог ΠΏΠΎΠ²Ρ€Ρ›Π° ΠΈΠ· Ρ„Π°ΠΌΠΈΠ»ΠΈΡ˜Π΅ Asteraceae.
