Sweet pepper (Capsicum annuum L.) is an annual herbaceous plant of the Solanaceae family, which is one of the most important agricultural crops due to its exceptional economic importance, the nutritional value of its fruits and its confirmed antioxidant activity. The aim of this work was to determine the influence of the application of calcite-based biostimulants during the growing season on the germination of sweet pepper seeds. In the 2019 growing season, the calcite-based biostimulants Eco Green and Zeogreen+P were foliar applied on two sweet pepper cultivars (bell fruit type – ‘Šorokšari’ and capia fruit type – ‘Kurtovska kapija’). At the end of the growing season, 300 seeds from each cultivar were collected (100 seeds from plants treated with each of the two biostimulants and 100 seeds from plants that had not been treated during the growing season - control) and placed for germination under controlled conditions at a constant temperature of 25 oC and a light regime of 16/8 h day/night. At the end of the experimental period, the seed germination parameters were calculated. It was found that the application of the calcite-based biostimulant Eco Green had a statistically significant positive effect on the germinability (G, %), mean germination rate (MR), the uncertainty of the germination process (U) and germination index (GI) in both cultivars and on mean germination time (MGT, day) in the cultivar ‘Kurtovska kapija’. The calcite-based biostimulant Zeogreen had no statistically significant positive effect on the germination parameters, except for the germinability (G, %) in the cultivar ‘Kurtovska kapija’.Paprika (Capsicum annuum L.) je jednogodišnja zeljasta biljka iz porodice Solanaceae, koja se zbog svoje iznimne gospodarske važnosti, nutritivne vrijednosti plodova i antioksidativnog djelovanja ubraja u najznačajnije poljoprivredne kulture. Cilj ovog rada bio je utvrditi utjecaj primjene biostimulatora na bazi kalcita tijekom vegetacije na klijavost sjemena paprike. Tijekom vegetacije 2019. dvije sorte paprike (babura - Šorokšari i rog - Kurtovska kapija) tretirane su biostimulatorima na bazi kalcita Eco Green i Zeogreen+P. Na kraju vegetacije sakupljeno je po 300 sjemenki od svake sorte (100 sjemenki s biljaka tretiranih svakim od dva biostimulatora i 100 sjemenki s biljaka koje nisu bile tretirane tijekom vegetacije – kontrola) i stavljeno na klijanje u kontrolirane uvjete pri konstantnoj temperaturi od 25 oC i svjetlosnom režimu od 16/8 h dan/noć. Na kraju pokusnog razdoblja izračunati su parametri klijavosti sjemena. Utvrđeno je da primjena biostimulatora na bazi kalcita Eco Green ima statistički značajan pozitivan učinak na klijavost (G, %), srednju stopu klijavosti (MR), pouzdanost procesa klijanja (U) i indeks klijavosti (GI) kod obje sorte te na prosječno vrijeme klijanja (MGT, dan) kod sorte ‘Kurtovska kapija‘. Biostimulator na bazi kalcita Zeogreen+P nije imao statistički značajan pozitivan učinak na parametre klijavosti, osim na klijavost (G, %) kod sorte ‘Kurtovska kapija‘
