Maize Physiology and Yield Data Under Drought Priming and Nitrogen Fertilizer Treatments

A 13.1 KB document by Jinhui Xie, uploaded to figshare on 2026-04-13, details an agronomic study on summer maize. The research explores how nitrogen fertilizer modulates the effect of drought priming on photosynthesis, antioxidant defense, nitrogen metabolism, and yield. Results include specific percentage increases in physiological metrics like net photosynthetic rate and grain yield.

Use Cases

• Modeling the relationship between nitrogen application and drought tolerance in maize based on described physiological metrics.
• Analyzing the synergistic effects of drought priming and fertilizer on crop yield components as detailed in the results.
• Training models to predict photosynthetic efficiency (Fv/Fm, ΦPSII, Pn) under combined water and nutrient stress.
• Studying root architecture development (root length density, surface area) in response to agronomic treatments.

Strengths

• Study reports specific, quantified results such as a 16.2% grain yield advantage and 28.9%-57.1% increases in antioxidant enzyme activities.
• Data is openly licensed under CC-BY-4.0, facilitating reuse and analysis.
• Research focuses on a clearly defined experimental setup comparing single drought treatment with combined priming and nitrogen application.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The primary data file is a 13.1 KB DOCX document, suggesting the dataset is very small and likely contains summarized results rather than raw observational data.
