There was tested an influence of three biostymulants Atonik SL, Biochikol 020 PC and Tytanit on yield and fruits quality of three fruiting repeating Polish raspberry cultivars: Pokusa, Polka and Poranna Rosa during years of 2005–2006. These agents had a positive influence on fruits quality and yielding to all tested cultivars. The fruits with exception of Tytanit treated fruit especially in the beginning of harvest, were characterized by better firmness and were bigger. However, Tytanit treatment increased soluble solids content in fruits and reduced in Polka cv. nitrates concentration. Among tested cultivars, cv. Polka was characterized by the highest yield, that was of c. a. 50% greater that of cv. Pokusa, which was characterized by the gratest fruits sizes. The ‘Poranna Rosa’ shawed the least soluble solids and vitamin C content and had the highest acidity.
