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<sup>-1</sup> (N<sub>90</sub> at the beginning of vegetation + N<sub>30 </sub>at 31 Zaddoks stage + N<sub>30 </sub>at 47 Zaddoks stage) at the background of Р<sub>40</sub>К<sub>80</sub> and aftereffect of 40 t ha<sup>-1</sup> FYM for winter triticale cultivation after clover on Luvisol loamy sand soil resulted in grain yield 72.6 c ha<sup>-1</sup>, output 98.7 c ha<sup>-1 f.u. At applied fertilizer system the content and output of raw protein were equal to 12.2% and 768 kg ha-1</sup> respectively, mass of 1000 seeds - 45.69 g, critical amino acid sum 7.27 g kg<sup>-1</sup> (grain) and 70.50 mg g<sup>-1</sup> (protein), biological value of protein - 101,4% (irreplaceable amino acid, FAO/WHO).
