Maize Growth Responses to Combined Warming, Drought, and Salinity Stress

A pot experiment investigated how warming modifies maize growth and resource-use efficiency when combined with drought or salinity. The study measured plant growth, water- and nitrogen-use efficiency, 15N fertilizer recovery, and Δ13C discrimination under three air temperature regimes and three water regimes. Findings show warming amplified the detrimental impacts of both drought and salinity on plant performance, sometimes resulting in non-additive responses.

Use Cases

• Modeling crop yield under combined climate stressors based on measured growth and resource-use efficiency.
• Analyzing non-additive stress interactions based on bootstrap-based effect size analyses described in the methods.
• Studying the impact of warming on nitrogen fertilizer recovery based on 15N tracer measurements.
• Investigating trade-offs between root and shoot growth under drought stress as described in the results.

Strengths

• Data originates from a controlled pot experiment with three distinct temperature regimes (+1.1 °C and +1.9 °C increases) and three water regimes.
• Includes specific physiological measurements such as 15N fertilizer recovery and Δ13C discrimination.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Dataset is very small at 35.2 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
