Effect of Different Nitrogen Supply on Maize Emergence Dynamics, Evaluation of Yield Parameters of Different Hybrids in Long-Term Field Experiments

This paper aims to examine the effect of various nitrogen (N) supply treatments on date emergence maize hybrids classified in different age groups. The study site was at University Debrecen’s Látókép Experiment Station Hungary. tested monitored under control (0 kg N ha−1), 120 ha−1 + PK, and 300 PK nutrient levels a long-term field experiment. In 2020, (H1 = FAO 490; H2: 420–440; H3 420; H4 H5 320–340; H6 350–370) growing natural precipitation conditions without irrigation were included study. During days emergence, moisture, protein, oil, starch, yield production observed, according variance analysis. diverse hybrids, increasing or decreasing fertilizer treatment resulted productivity metrics. Regression analysis revealed that day had greater impact oil content than fertilizer; however, influenced by fertilization, rather emergence. Regarding parameters, this suggests H1 has best until fourth
