RESPONSE OF MAIZE AND WHEAT TO INCREASING RATES OF NPK-FERTILIZATION
The stationary field experiment with increasing rates of NPK 8:26:26 fertilization was conducted on acid soil. Three steps of NPK-fertilization were applied (kg ha-1) as follows: F-1 = 103 N + 52 P2O5 + 52 K2O, F-2 = 133 N + 182 P2O5+ 182 K2O and F-3 = 183 N + 312 P2O5+ 312 K2O. Six hybrids of maize...

| Summary: | The stationary field experiment with increasing rates of NPK 8:26:26 fertilization was conducted on acid soil. Three steps of NPK-fertilization were applied (kg ha-1) as follows: F-1 = 103 N + 52 P2O5 + 52 K2O, F-2 = 133 N + 182 P2O5+ 182 K2O and F-3 = 183 N + 312 P2O5+ 312 K2O. Six hybrids of maize (the growing seasons 2008-2010) and winter wheat (2010/2011) cultivar Renata were grown in crop rotation. In our study, considerable subsequent effects of applied fertilization on wheat yields were found as follows: 7.44 t ha-1 (F-1), 8.74 t ha-1 (F-2) and 8.43 t ha-1 (F-3). However, maize responded by yield decreases up to 7% (3-year means: 10.76, 10,50 and 10.02 t ha-1, for F-1, F-2 and F-3, respectively). |
