Integrated and ecological arable farming systems were established on brown clay loamy soil in the fall of 1991 near Nitra, in South Slovakia region. The altitude of experimental field is 178 m, average year temperature is 9.6 oC and annual precipitation is 523 mm. In the 2003-2006 the effect of two different farming systems (ecological and integrated) and two levels of fertilization on qualitative parameters of spring barley and winter wheat were observed. System of farming and fertilization did influenced content of protein and extract of spring barley. Falling number of winter wheat was significantly influenced by all observation factors. Gluten index and wet gluten were depended on climatic conditions but gluten index was not statistically influenced by system of farming.
