Overview

Randomized trial evaluates yield and water productivity in maize with dense planting and regulated deficit irrigation, suggesting improved practices for sustainable agriculture.

Key Points

  • The study aims to improve maize grain yield and water productivity under water scarcity through high-density planting and regulated deficit irrigation.
  • Conducted a multi-region field experiment across various climates in Xinjiang, China.
  • Compared conventional practices with an optimized high-density production model using precision-regulated irrigation.
  • Implemented four deficit irrigation treatments with varying reductions in water compared to full irrigation.
  • Synergistically increased grain yield by 18.8–25.0% in comparison to conventional practices.
  • Water productivity improved by 8.7–20.0% across sites with the optimized model.
  • Achieved water savings of 11.1–50.0% by maintaining soil water storage at around 70% of field capacity.
