Short Summary

This study optimized stage-based water table depth for lettuce cultivation under subsurface evapotranspiration irrigation, demonstrating improved water use efficiency and productivity. The findings highlight the importance of integrating water table management with crop evapotranspiration-based scheduling.

Objective

• Investigate the impact of stage-based water table depth on lettuce growth performance and fresh yield under subsurface evapotranspiration irrigation

Study Configuration

• Spatial Scale: Field-scale experiment (1 ha)
• Temporal Scale: 12-week growth period, with four distinct growth stages

Methodology and Data

• Models used: None mentioned in the paper
• Data sources: Root-zone moisture monitoring using sensors and/or tensiometers, irrigation scheduling based on crop evapotranspiration (ETc = ET0×Kc)

Main Results

• Stable water table control is essential for maintaining near-optimal root-zone moisture under daily ET fluctuations.
• Vertical–horizontal moisture distribution patterns are affected by soil–sand media composition, influencing moisture uniformity and deep percolation risks.
• Lettuce growth performance and fresh yield improve under optimal moisture thresholds but decline under deficit conditions or mild waterlogging.

Contributions

• This study provides original insights into the importance of integrating stage-based water table management with ET-based scheduling for enhancing water use efficiency while sustaining productivity in lettuce cultivation.

Funding

• Not specified in the paper
