The aim of the pot experiment was to determine the impact of timing of nitrogen application in the form of ammonium nitrate enriched with the 15N isotope, on the uptake of 15N by spring barley plant and its distribution in grain, awns, leaves, straw, and roots. 1.21 g of N per pot containing 10 kg of the soil was applied at two doses: 2/3 before the sowing, and 1/3 at the tillering phase or at the stalk-shooting phase. The distribution of the applied nitrogen, assumed as 100%, was the highest in grain (61.5%), and the lowest in roots (4%). The mean nitrogen utilisation coefficient value (%) measured with the difference method was 86.9 %, and that for the isotope dilution method – 61.0%. Postponing the time of nitrogen application from the tillering to the stalk-shooting phase differentiated the nitrogen utilisation coefficient value, which was higher for the difference method than for the isotope dilution method and it amounted to +32.3% at the tillering.
