Wheat and Weed Competition Data with Nitrogen Fertilization and Trait Measurements

A competition experiment involving 2490 individuals of wheat and two weed species (Avena fatua and Echinochloa crus-galli) grown in a response-surface design. The dataset, created by weiqiang liu and last updated in June 2026, includes measurements of individual seed production and functional traits like plant height, leaf area, and root traits under nitrogen-fertilized and unfertilized conditions.

Use Cases

• Modeling crop-weed competitive outcomes based on parametrized population models from seed production data.
• Analyzing the effect of nitrogen addition on plant functional traits such as root area and specific leaf area.
• Investigating species-specific mechanisms of coexistence through calculated niche and fitness differences.
• Informing the selection of wheat varieties for sustainable agriculture based on trait plasticity data.

Strengths

• Includes data from 2490 individual plants, providing a substantial sample for analysis.
• Measures multiple functional traits at the individual level, including plant height, leaf traits, and five root traits.
• Experimental design includes both nitrogen-fertilized and control conditions, allowing for direct comparison.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 314.0 KB, indicating a limited scope.
