russe. При возделывании ячменя на дерново-подзолистой супесчаной почве оптимальной системой удобрения является применение N60+60P30K120 (азотные удобрения вносили в два приема: N60 – под культивацию, N60 – в фазе 2–3 листьев) на фоне последействия 50 т/га органических удобрений. Данная система удобрения обеспечила максимальную в опыте урожайность зерна 43,8 ц/га при содержании белка 12,0%. Удельный вынос основных элементов питания составил: азот – 20,5 кг/т, фосфор – 8,7 кг/т, калий – 22,8 кг/т.

In course of the research there was studied the effectiveness of the use of fertilizers in the cultivation of barley (Hordeum vulgare) on sod-podzolic sandy loam soil. The long-term stationary experiment was realized in the conditions of the Republic of Belarus on the experimental field of RUE ‘Grodno Zonal Institute of Plant Growing’ on a background of the aftereffect of 50 t/ha of manure to ensure maximum removal of total phosphorus - 41 kg/ha. As a result of realized research there was revealed that optimum fertilizer system of barley cultivated on sod-podzolic loamy sand soil was the application of N6CH60P30K120 (nitrogen fertilizers were applied in two steps: N60 - cultivation N60 - in the phase of 2-3 leaves) on the background of the aftereffects of 50 t/ha of organic fertilizers. This fertilizer system provided the maximum grain yield to 43.8 c/ha at the protein content of 12.0%. Specific removal of the main nutrients formed: nitrogen – 20.5 kg/t, phosphorus – 8.7 kg/t, potassium – 22.8 kg/t.
