- •
Optimal coupling combinations between irrigation rate and glycinebetaine level for improving yield and WUE of drip-irrigated maize were examined.
- •
Different drip irrigation rates and glycinebetaine levels were tested.
- •
Effects of glycinebetaine depended on the level of glycinebetaine within the same irrigation rate.
- •
A threshold level of GB is required for a positive effect.
