ABSTRACT

In the paper effects of two complex blended fertilizers on yield and content, as well as accumulation of macronutrients by oats are presented. From the results of three-years lasting field trial it can be concluded that application of complex blended fertilizers (under commercial names Amofosmag 4 and Amofosmag 3) did not affect oats grain and straw yields in comparison to control (straight NPK fertilizers). Content of studied macronutrients in grain appeared to be unaffected by fertilization treatments. However, significant differences of chemical composition of oats tissues were noted between seasons of studies what indicated impact of weather conditions. The highest total uptake of nitrogen and potassium by oats yield was found in Amofosmag 3 treatment whereas total uptake of phosphorus was the highest in control treatment.

Key words: oats, yield, macronutrients, complex fertilizers.
