Rezumat: The measured data of N2O emissions were used to test the DNDC model from cropland during the growing season of spring barley (April-July in 2012) in Slovakia. There wasn’t found a good agreement with seasonal N2O emissions. The relative deviation between observed and simulated total seasonal N2O emissions (kg N ha-1) from two treatments were 91% and 281% for treatment without and with N fertilizer (N0 and N1), respectively. Also some discrepancies were found between observed and simulated emissions when evaluating the daily N2O emissions, especially when looking at the magnitude of N2O emissions peaks. The correlation between observed and simulated daily N2O emissions was r = 0.72 (n = 18, P < 0.01) and r = 0.56 (n = 18, P < 0.05) for N0 and N1 treatment, respectively.
