The biological material used consisted of the cultivar “Asteroid 204”. Three foliar treatments were applied, from fruit setting, with calcium nitrate alone or in combination with three seaweed-based biostimulants (Agrocean B, E-Dalgin and Kelpak), two based on microorganism inoculum (Triptolemus HV and Albit), and three mixed bistimulants (Sprintene, Kinactiv Fruit and Rerum). The mass of a fruit, the number of fruits per plant and the yield were determined, and for the assessment of quality - the firmness and thickness of the pulp, the total dry matter content, the total soluble solids, and the level of titratable acidity. The combined use of calcium nitrate with various biostimulants, such as Kelpak, Sprintene, Kinactiv Fruit or Rerum, increases production and improves some quality traits.Englishbiostimulatoricalitatea fructelorCapsicum annuumproducțieArticle2069-8275
