Abstract
The field experiment, concerning the effect of fertilization with ammonium nitrate with the addition of microelements on the oat grain protein, was realized in 1999–2001 at the ATR Research Station at Wierzchucinek near Bydgoszcz, on a good rye type soil. Oat of the Komes variety was fertilized with ammonium nitrate, the Magmol (i.e. ammonium nitrate enriched with magnesium and molybdenum), and with ammonium nitrate with the addition of the Sonata — a multi-component microelement fertilizer, in doses: 3 kgha-1 and 6 kgha-1. Fertilization with ammonium nitrate only resulted in a distinct decrease in quality of the oat grain protein, measured with the value of the essential amino acid index, lower by 13.21% with reference to the control object. The value of essential amino acid index in the objects with microelements supplementation was lower only by 7.96% on average, in comparison to the control. The application of microelements with ammonium nitrate significantly decreased the negative effect of nitrogen fertilization on the protein quality of the tested plant.
