The Influence of Mineral Fertilizers on the Maize Hybrids Yield and Grain Quality

In the study examines the influence of the form and amount of nitrogen on the morphological and productive properties of maize production. Trials were conducted during the 2024 year on a private property in Novi Kozjak and on land of the degraded chernozem type with maize hybrid P0 216. The mineral fertilizers UREA (46% N), CAN (27% N) and AN (34.4% N) were used as a form of nitrogen for feeding maize in amounts of 50 and 100 kg ha-1 of active matter. The obtained results showed a significantly greater influence of the amount of nitrogen compared to the form of nitrogen, on all parameters included in the research. With the use of a larger amount of nitrogen (100 kg ha-1), the increase in the values of the examined parameters of maize productivity varied in the interval from 2.1% to 5.8% compared to a smaller amount of N (50 kg ha-1). The highest values of morphological characteristics were determined in the treatment where AN, as a form of nitrogen, was applied. On the other hand, the highest yield of maize grains (12.81 t ha-1) was obtained on the variant where UREA was used for feeding.
