The field experiment was carried out on a sandy loam soil classified as Albic Luvisols in 2002-05. Treatments included three tillage systems (conventional, simplified soil tillage and direct sowing) and four levels of nitrogen fertilization (0, 50, 100, 150 kg/ha). The purpose of the study was to determine the effect of tillage systems on effectiveness of nitrogen fertilization of winter wheat. Agronomic and physiological efficiency decreased with doses of nitrogen for all estimated tillage systems
