Abstract: The aim of this study is to determine the optimum quantity of nitrogen applied in corn production at which maximum profit is achieved. Optimal nitrogen application is important for two main reasons: first for achieving maximum profitability in the production of maize and other is to avoid environmental pollution as the nitrogen is one of the main polluters. In the three-year period (2005 - 2007) were performed research on the effects of nitrogen quantity (control - without fertilization, PKNfon, PKN60, PKN120 and PKN180) and hybrids of different vegetation length (ZPSC 434 ZPSC ZPSC 578 and 677) on yield and profitability. Increasing application of nitrogen tended to raise grain yield by 9.9 - 13.5%. The lowest average corn grain yield (9.49 t ha-1) was registered with the hybrid ZP 434. It was somewhat higher (9.75 t ha-1) with the hybrid ZP 578 and the highest corn grain yield (10.03 t ha-1) with ZP 677. Study shows that highest yield is not always most profitable. In production year with good water supply (2005) highest profit is achieved with moderate use of nitrogen (60 kg ha-1). In drought production years (2006 and 2007) highest profit was achieved with application of 60 to 120 kg ha-1.
