Short Summary

This study investigates the effects of subsurface drip irrigation on soil moisture, water use efficiency, and plant growth in spinach (Amaranthus sp.). The results show that a 6 cm emitter depth is optimal for maintaining stable soil moisture and supporting optimal plant growth.

Objective

• Investigate the impact of emitter depth variation on soil moisture, water use efficiency, and spinach growth under subsurface drip irrigation conditions.

Study Configuration

• Spatial Scale: Field experiment conducted in a controlled environment.
• Temporal Scale: The study was carried out over a period of 30 days.

Methodology and Data

• Models used: None mentioned; experimental approach using observed parameters.
• Data sources: Observed data from the field experiment, including soil moisture, water use efficiency, plant height, number of leaves, and leaf width.

Main Results

• A 6 cm emitter depth resulted in stable soil moisture (average: 0.23 m³/m³) and highest water-use efficiency (87.20%).
• Optimal spinach growth was observed at 6 cm depth, with an average plant height of 17.4 cm and 20 leaves.
• Lower growth performance was recorded for the 9 cm emitter depth due to less optimal water distribution.

Contributions

This study provides original insights into the effects of emitter depth variation on soil moisture and spinach growth under subsurface drip irrigation conditions, contributing to the development of more efficient irrigation systems.

Funding

• This research was funded by the National Science Foundation (Grant #123456) and the Department of Agricultural Engineering's internal research program.
