Implication

Simulation reveals deficit irrigation boosts irrigation water use efficiency in grain sorghum, suggesting sustainable practices for the Texas High Plains.

Key Points

Implementing growth-stage-based deficit irrigation strategies significantly improves irrigation water use efficiency and yields.
The boot to early grain filling stage is identified as the most sensitive period to water stress for grain sorghum.
A strategy conserving 30% of evapotranspiration in the first stage while using 90% in the later stages proves ideal for yield.
Results indicate water savings of 12.2% with minimal yield loss compared to traditional full irrigation methods.
