Overview

Field experiments demonstrate improved maize yields with nitrogen fertilizer and supplementary irrigation, highlighting sustainable farming practices.

Key Points

  • Grain yield improved by 356% with 69 kg N ha −1 and 75% crop evapotranspiration irrigation compared to rain-fed conditions.
  • Optimum maize yield reached 9.10 t ha −1 when applying specific nitrogen and irrigation levels.
  • Split-plot factorial experiments conducted in 2019 and 2020 focused on different nitrogen and irrigation rates.
  • Findings suggest sustainable management practices to enhance maize productivity under moisture stress conditions.
