Wheat is an important food crop and is by far the most popular cereal in Europe, Romania being among the six important producers. In Giurgiu County at S.C. AZOCHIM S.R.L farm it was designed a field experiment for investigation of variability of the yield components (yield, plant height, spikes/m2, number of grains per ear, thousand kernel weight TKW) and variability of quality parameters (wet gluten and crude protein contents) influenced by mineral fertilization and wheat variety. It was developed a bifactorial experiment where a factor was wheat variety (Glosa, Miranda) and b factor was fertilization. It was adopted three fertilization schemes: starter (NPK 16:16:16) (V1), starter (NPK 16:16:16) + CAN (calcium ammonium nitrate) + AN (ammonium nitrate) (V2) and starter (NPK 16:16:16) + UAN (urea ammonium nitrate) (V3). An efficient nitrogen transfer into grains was obtained by splitting nitrogen fertilization. The results indicated that three applications of liquid fertilizer UAN (V3) increased the proteins levels and produced the highest yields for both wheat varieties. The same trend was recorded for plant height, spikes/m2, number of grains per ear and for quality parameters. Concerning TKW, fertilization did not lead to significant differences, but it was observed higher values forʻMiranda in comparison with Glosa.
