Efficiency of of organic and mineral fertilizers application under winter tritikale on sod-podzolic soils

Abstract

At winter triticale cultivation on sod-podzolic soils the maximal productivity is received in variants with N70+30Р60К120 application on a background of 2-nd year aftereffect of growing dozes of manure. On light loam soil the grain productivity in these variants has made 77,0-79,9 c/ha at a recoupment of mineral fertilizers of 1 kg on the average 9,0 kg of grain, 1 t manure - 8,8 kg. The net profit has made 111-146 thousand roubles at profitability of 17-26%. Application of mineral fertilizers on a background of 20-60 т/га manure aftereffect on loose sandy loam soil has provided formation of productivity of a grain winter tritiсale at a level 68,5-72,9 ц/га. Each kg NРК thus paid off by 9,1 kg of grain tritiсale, 1 t manure - 24,4 kg. The net profit has made 155-165 thousand roubles at profitability 23-29%. Specific output of nutrients with crop yield of winter tritiсale has made on the average 17,8 kg of nitrogen, 9,7 kg of phosphorus, 15,3 kg of potassium, 1,3 kg of calcium and 1,9 kg of magnesium.
