Field experiments demonstrate enhanced grain yield and water use efficiency in winter wheat through optimal nitrogen application rates.

This research aims to identify optimal nitrogen application rates for maximizing winter wheat yield and water efficiency.
Conducted field experiments with varying nitrogen application rates (0 to 300 kg ha⁻¹)
Measured growth parameters, nitrogen absorption, yield, and protein content
Analyzed soil water consumption and water use efficiency
Nitrogen application significantly improved growth parameters
N210 and N240 treatments optimized nitrogen accumulation and yield components
Highest water use efficiency observed in N240 treatment
Grain yield was maximized under N210 and N240 conditions

Qu et al. (2025) studied this question.
