This paper presents a one-year study (2023-2024) of 10 winter 2-rowed barley genotypes concerning the effectiveness of nitrogen fertilization on quality parameters that seeds need to accomplish for malting barley. The experiment was conducted at National Agricultural Research and Development Institute Fundulea, in Southeast Romania. The genotypes were sowed in the 2023 year in two technological sequences in 3 replications (T0 - 0 kg urea/ha and T1 - 100 kg urea/ha). It was revealed that were no significant differences in yield between the unfertilized (T0) and fertilized (T1) experience, the difference between the mean value of the experience was 635 kg/ha. The lowest value for protein content to be accepted by the malting industry was registered by the Gabriela variety (T0 - 11.47%) meanwhile the highest value of the experiment was registered by the Ileana variety (T1 - 15%) which indicates a suitable variety for animal forage. Starch content ranged between 61.2% (T0) and 63.9% (T1). A significant difference was observed in grain plumpness between the technological sequences as follows: the mean of the dataset for (T1) was 94.04% compared with 69.51% (T0).
