Randomized trial evaluated sorghum performance under irrigation and salinity levels, suggesting effective strategies for resilience.

This research aims to assess the impact of irrigation regimes and soil salinity on sorghum productivity using the AquaCrop model.
Field trials conducted in 2023–2024 assessed sorghum under irrigation regimes of 70-75-70%, 65-70-65%, and 60-65-60%.
Irrigation treatments were applied with and without pre-season soil salinity leaching, designated T1 through T6.
Yield measurements included sorghum biomass and water productivity across different treatments.
Under treatment T5, sorghum biomass reached 60.9 Mg ha −1 in 2023 and 59.77 Mg ha −1 in 2024, indicating superior productivity.
Plots with salt leaching (T4) yielded 58.21 Mg ha −1 in 2023 and 57.64 Mg ha −1 in 2024, showing significant decreases under T1.
Water productivity increased by 21.5–36.1% in desalinized plots compared to unleached plots, highlighting effective irrigation strategy.

Sindarov et al. (2026) studied this question.
