Tomato Yield and Stress Tolerance Data Under Deficit Irrigation

A field experiment evaluated foliar-applied melatonin's effect on tomato plants under drought stress. The dataset likely contains measurements of plant height, yield, chlorophyll content, water status, and antioxidant activity across two irrigation regimes and five melatonin concentrations. The data was authored by El-Sayed M. Desoky and uploaded to figshare in May 2026.

Use Cases

• Modeling the relationship between melatonin concentration and yield improvement based on reported yield increase percentages.
• Analyzing physiological stress markers such as electrolyte leakage and malondialdehyde content under deficit irrigation.
• Studying the upregulation of enzymatic antioxidants (SOD, POD, APX, CAT, GR) in response to biostimulant application.
• Evaluating the efficacy of different irrigation regimes (100% ETc vs. 60% ETc) on fruit production metrics.

Strengths

• The experiment employed a split-plot design with three replications, suggesting a structured experimental approach.
• Results include specific percentage changes (e.g., yield increased by 51.8% with 100 µM MT) for key physiological parameters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 249.7 KB PDF file; the underlying structured data may require extraction.
