Chinese Rainfed Maize Yields and Management Practices for Crop Model Calibration

A dataset compiled from publicly available Chinese literature documents observed maize yields, growth periods, and agricultural management practices like fertilization and irrigation. It contains 284.6 KB of data in XLSX format, created by Fangzheng Chen and last updated on June 3, 2026. The data was used to calibrate maize cultivar parameters in the APSIM crop model for a study on climate change and drought impacts.

Use Cases

• Calibrating crop model parameters based on observed yield and growth period data.
• Analyzing the relationship between management practices like irrigation and fertilization and maize yield outcomes.
• Studying the variability of rainfed maize production across different regions in China.

Strengths

• Includes complete bibliographic details for all entries to facilitate source retrieval.
• Provides detailed variable descriptions in a separate sheet named 'Information'.
• Explicitly documents agricultural management practices such as fertilization and irrigation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent from the provided metadata; field semantics must be inferred after download.
• Some source studies are hosted on CNKI, which may be geographically restricted outside mainland China.
