In recent years, cereals have been increasingly grown in simplified crop rotations. The aim of the study was to determine the grain yield of winter triticale cultivars Cerber, Alekto and Fredro under plow or plowless tillage systems and different crop rotations. A three-year study was conducted at the Experimental Station of Soil Science and Plant Cultivation State Research Institute in Puławy, Poland. The yield of winter triticale depended on the weather conditions, crop rotations, method of tillage, and genetic factor. Under optimal rainfall, higher yields of winter triticale grain were obtained under ploughing. The grain yield was higher by 15 % compared to the simplified cultivation. In the crop rotation with a small percentage of cereals, the highest level of triticale yields was recorded, while lower triticale yields were obtained in the crop rotation with a large percentage of cereals. In plough cultivation conditions cvs. Cerber and Alekto showed higher yields (8.31 and 6.78 t·ha-1), whereas in simplified cultivation lower grain yield was (6.09 t·ha-1) cv.Fredro. Grain monoculture contributed to lowering the level of winter triticale yield.
