The research has shown that the maximum average daily absorption of nitrogen, phosphorus, potassium was noticed at the tasseling. Applying of 120 t/ha of manure and mineral fertilizers N120P40K90 has provided the highest consumption of nitrogen 207,4 kg/ha, phosphorus 108,2 kg/ha and potassium 221,8 kg/ha. Dry mass accumulation was 130,8 c/ha and grain yield – 78,6 c/ha. Nevertheless intensive daily average absorption of nutrients at the end of vegetation was marked on a background of manure of 80 t/ha and N120P40K90. Applying of N120P40K90 increased the phosphorus absorption in 2,4 times in accordance to the control variant and in the phase of milk ripeness made 43,5 kg/ha
