The field experiment was carried out at the Mochelek Experiment Station of the Faculty of Agriculture, University of Technology and Agriculture over 1984-94. Its aim was to define an effect of nitrogen fertilization on the amino acid composition in winter barley grain protein. Four levels of nitrogen fertilization: 0, 60, 120 and 180 kg N/ha were investigated. Applying 120 kg N/ha results in a lowered content of most amino acids, the exogenous ones especially, as compared with the control. The total sum of amino acids in the winter barley grain protein decreased from 893.2 g/kg in the control to 846.1 g/kg in the object treated with 180 kg N/ha
