The aim of this research was to obtain the influence of fertilization level and sowing density on changes in the grain yield of the winter triticale cv. Woltario. The experiment was conducted in micro plots (square m) at the Institute of Soil Science and Plant Cultivation - State Research Institute (PIB) in Pulawy, Poland over 1999-2002. The factors were: NPK fertilization level: 160, 260 and 360 kg/ha and sowing density (100, 200, 300 grains/square m). It was found that the biggest grain yield was obtained under a density of 200 plants/square m and a fertilization level of 260 kg NPK/ha. Further increase in plant density and nitrogen fertilization did not influence yield level. Variability of the grain yield depending on the studied factors was related mainly to differentiation in the number of ears per area unit
