Field experiments were conducted at the Brody Experimental Station of Poznan University of Life Sciences in 2009–2010. The aim of this study was to determine leaf and stem base and root diseases severity on spring barley as an effect of different tillage systems (conventional, reduced and direct drilling). Fusarium spp. and Gaeumannomyces graminis occurring on stem bases and roots were the main pathogens identified on spring barley. The intensity of occurrence of stem base and root diseases increased under reduced tillage and direct drilling systems as compared with phloughing system. A higher infection with Pyrenophora teres was observed on barley leaves under reduce tillage system and direct drilling comparing to conventional tillage system. The occurrence of Puccinia hordei and Rhynchosporium secalis was lower under ploughless tillage systems.
