INFLUENCE OF FERTILIZER SYSTEM ON QUALITY OF WINTER TRITICALE GRAIN GROWN ON LUVISOL LOAMY SAND SOIL
It was found that 3-term nitrogen introduction in doses of 150 kg ha-1 (N90 at the beginning of vegetation + N30 at 31 Zaddoks stage + N30 at 47 Zaddoks stage) at the background of Р40К80 and aftereffect of 40 t ha-1 FYM for winter triticale cultivation after clover on Luvisol loamy sand soil resulted in grain yield 72.6 c ha-1, output 98.7 c ha-1 f.u. At applied fertilizer system the content and output of raw protein were equal to 12.2% and 768 kg ha-1 respectively, mass of 1000 seeds - 45.69 g, critical amino acid sum 7.27 g kg-1 (grain) and 70.50 mg g-1 (protein), biological value of protein - 101,4% (irreplaceable amino acid, FAO/WHO).
