The aim of the conducted study was to determine to what extent the cultivation of sweet pepper lowers the phytotoxicity of a substrate. The examined material was a highly phytotoxic substrate due to repeated cucumber growing on it. This substrate was a mixture of pine and beech bark, low peat and sawdust. Five sweet pepper cultivars: Amador, Bell Boy, Culinar, Poznańska Słodka and WSE 2/82 were planted. During vegetation of the sweet pepper phytotoxicity and phenolics levels were determined in the substrate. It was found that cultivation of sweet pepper had a significant effect on lowering phytotoxicity and phenolics content in the substrate. Among the five tested cultivars, the highest detoxicating ability was exhibited by Amador, Culinar and WSE 2/82 while the Poznańska Słodka did not show such abilities.
