- •
A two-year field and modeling study was carried out to evaluate the influence of various water-saving irrigation techniques on maize response.
- •
HYDRUS-2D was capable of simulating the components of the soil water balance for both full and water-saving irrigation treatments.
- •
PRD75 treatment maintained favorable evapotranspiration rates while the DI treatments caused a considerable reduction in root water uptake.
- •
HYDRUS-2D can be successfully used to optimize various water management strategies under local water-stress conditions.
