Overview

Field experiment shows enhanced crop productivity and water use efficiency with specific nitrogen treatments in maize, suggesting improved water management practices.

Key Points

  • Maximum yield achieved with 204 kg ha−1 nitrogen, showing a 32% increase over control.
  • Water use efficiency improved as nitrogen application rose during the 2021–2022 growing season.
  • Observational analysis including four nitrogen fertilization treatments and simulations retrieved with the HYDRUS-2D model.
  • These findings highlight the need for optimized nitrogen and water management in regions facing water scarcity.
