Field experiments were conducted in 2006–2008 at the Złotniki Experimental Station of Poznań University of Life Sciences. The aim of this study was to determine leaf and ear disease severity on spring triticale as affected by irrigation variant, tillage systems and nitrogen fertilization. The occurrence and severity of symptoms of diseases caused by fungal pathogens on spring triticale largely depend on weather conditions. The least conducive conditions for the development of fungal diseases occurred by the year 2008, in which there was no signs of their presence. Sprinkling irrigation increased infection of spring triticale by Blumeria graminis. Direct drilling in comparison to conventional tillage system, increased infection caused by Puccinia recondita on the flag leaf and by Cladosporium herbarum on ear, but only in a single year of study. Nitrogen fertilization significantly increased leaf area damaged by fungal diseases.
