| ABSTRACT Agricultural intensification to improve wheat yield has increased the demand for nitrogen fertilizers. This study aimed to investigate the wheat response in succession to soybean due to application of nitrogen rates and sources in top dressing, as well as to determine the N rates of maximum technical yield (MTY) and maximum economic yield (MEY). A field experiment was carried out in Ponta Grossa, Paraná State, Brazil, on a clayey Typic Hapludox (Oxisol) under a continuous no-till. A randomized block design was used, with 3 replications in a 4 × 3 complete factorial arrangement. The treatments consisted of a control and 3 N rates at 40; 80 and 120 kg∙ha−1 as calcium nitrate (CN), ammonium sulfate (AS), and urea (UR) in top dressing at tillering of... |
