Abstract:
This paper aims to show the influence that nitrogen fertilizer has on the quality of wheat. Research has been carried out
at Lovrin Agricultural Development Research Center, introducing a long-lasting fertilizer experience between 2015 and
2016 on Ciprian's wheat variety. The applied nitrogen fertilizers had the following graduations: 0, 30, 60, 90, 120 kg
nitrogen active substance/ha. Speaking about the quality of wheat, it is inappropriate to refer only to the percentage of
protein and wet gluten. The gluten structure is important for a high quality raw material in the milling and bakery
industry. Chemical nitrogen fertilizers do not only influence the amount of wet gluten but also that of gliadins,
glutenins, the accumulation of high molecular weight glutenin subunits and gliadin - glutenin ratio. Between the doses
of nitrogen applied, the amount of glutenin and the proportion of HMW units of glutenin there is a significant positive
correlation, statistically assured at α = 5% (r = 0.95 * for glutenin, r = 0.90 * for HMW subunits).
