YIELD AND REMOVAL OF THE SUPPLY ELEMENTS WHEN SINGLE-SPECIES AND MIXED ANNUAL CROPS FORAGE CROPS, WITH THE PARTICIPATION OF AMARANTH

 The preservation and the expanded reproduction of soil fertility are possible with a full refund used by plants and unproductive lost organic part of soil and nutrients. The use of amaranth in mixed crops increased content of nitrogen, phosphorus and potassium in green mass of annual grasses. The content of nitrogen on average over three years of research was in the range of 1.32–2.57 % at ADM. The maximum amount of nitrogen was available in single crop amaranth — 2.41–2.57 %. The highest amount of phosphorus and removal with harvest observed in crops amaranth with sudan grass, corn and panic at the ratio of 40 + 60 %. In single-species crops of the highest potassium content was provided by crops amaranth and was 3.17–3.36 % on ADM. Sudan grass, corn and panic accumulated potassium in the range of 1.62–1.69 %, 1.64–1.70 % and 1.64–1.68 % in ADM. The analysis yields single-species and mixed planting annual grasses involving amaranth shows the productivity of crops at the level of 14.11–26.33 t/ha of green mass on the ground level of the planned yield and 16.21–39.11 t/ha on the second. The removal of nitrogen single-species crops on average over the three years was 13.20–25.70 kg/t of dry substance (ADM), phosphorus — 1.80–2.20 kg/t ADM, potassium — 16.10–33.70 kg/t ADM, mixed crops — 16.30–21.00, 1.80–2.20 and 17.80–23.80 kg/t ADM respectively. The use of mineral fertilizers has contributed to the increase in the content of mineral substances in green mass and takes away their harvest. The biggest take-away batteries with 1 ha observed in the variants with the ratio of components 80 + 20 and 60 + 40 %
