Quantifying the Impact of Varied Nitrogen Fertilizer Dosages on Maize (Zea mays L.) Crop Growth and Yield

Abstract

This research investigates the influence of diverse nitrogen fertilizer dosages on the growth and yield of maize (Zea mays L.). Employing nitrogen application rates of 60, 80, 100, 120, and 150 kg ha⁻¹, we conducted a comprehensive field study to quantify the impact of varying nutrient levels on key agronomic parameters. The experiment aimed to elucidate the optimal nitrogen dosage for enhancing maize crop productivity while minimizing environmental impact. Results revealed distinct responses in terms of plant height, leaf area, biomass accumulation, and grain yield across the different nitrogen treatments. Additionally, the study assessed nitrogen use efficiency and potential environmental implications associated with the varied dosages. The findings contribute valuable insights into the nuanced relationship between nitrogen fertilization and maize crop performance, providing a foundation for informed agricultural practices that balance yield optimization and sustainable resource management.
