In recent years cereals, including triticale, have been more often grown in simplified crop rotations. This study aimed to determine the effect of zero tillage and ploughing on the yield level of winter triticale cultivars Pizarro and Pigmej under conditions of 50, 75 and 100% of cereals in the structure of cropland. The study was conducted in 2010/2011 and 2013/2014 at SD IUNG – PIB in Osiny in the soil classified as the good wheat complex. Yield of winter triticale depended mainly on the course of the weather conditions and the winter triticale cultivar. Tillage systems did not exert the explicit effect on yield of winter triticale. The cultivar Pigmej gave higher yields than cv. Pizarro. At moderate rainfall deficit, plants cultivated with simplified tillage managed better, whereas at the optimal rainfalls, ploughing ensured higher grain yields of winter triticale. The highest yields of winter triticale were obtained at 50% of cereals in the structure of cropland, and the lowest under conditions of cereal monoculture.
