Optimized irrigation methods led to significant improvements in water use efficiency, increasing it by 18.7%.
Drip and micro-sprinkler systems reduced irrigation water and nitrogen inputs by 35.1% and 7.2% without reducing yields.
Moderate deficit irrigation optimized productivity while maintaining stable yields despite varying soil conditions.
Climatic factors negatively correlated with irrigation benefits, indicating efficiency gains are better under drier conditions.
