Fresh Waxy Maize Yield Data from a Two-Year Field Experiment in Shanxi, China

Experimental data from a two-year field study investigating the effects of nitrogen application rate and planting density on fresh waxy maize yield. The dataset likely contains measurements of fresh ear yield, weight per ear, and dry matter and nitrogen accumulation. It was authored by Chunxia Jiang and last updated on 2026-05-22.

Use Cases

• Modeling the relationship between nitrogen application rate and fresh ear yield based on the described experimental treatments.
• Analyzing the trade-off between planting density and individual plant performance based on dry matter accumulation metrics.
• Identifying optimal agronomic management strategies for waxy maize based on the combination of nitrogen and density factors.
• Training models to predict crop yield under different nitrogen and density scenarios in rain-fed agriculture.

Strengths

• Data is derived from a controlled field experiment with a split-plot design and three replicates, suggesting a structured methodology.
• The study explicitly tests four nitrogen application rates (0, 120, 180, and 240 kg ha⁻¹) and two planting densities (45,000 and 60,000 plants ha⁻¹).
• Results identify a specific optimal combination (180 kg N ha⁻¹ and 60,000 plants ha⁻¹) for maximizing fresh ear yield.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The geographic scope is limited to a study area in Shanxi province, China, which may affect generalizability.
