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.
