First-Year Crop Yield Response to Lime Application Rates in Rwanda

Plot-level yield measurements for maize, French beans, and potatoes from 93 on-farm trials in Rwanda. The data was generated by the GAIA project to quantify yield responses to four lime application rates in a randomized complete block design. Predicted soil properties from external datasets can be linked via a unique soil sample identifier.

Use Cases

• Modeling crop yield response functions based on lime application rates.
• Analyzing spatial variability in soil acidity management outcomes based on the 93 farm sites.
• Calibrating soil-crop simulation models using the first-year experimental yield data.
• Assessing the economic feasibility of lime investments based on initial yield gains.

Strengths

• Data from 93 farm replications provides a substantial sample for analysis.
• Experimental design follows a randomized complete block design (RCBD), a standard for field trials.
• Includes a lookup table for harmonized agronomic terminology to facilitate interoperability.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Contains only first-year yield data; multi-year response trends are not captured.
• Soil properties are predicted from external datasets and require separate download and linking.
