Information about funding sources that supported the collection of the data: This work was supported by the Program of Accompanying Research for Agricultural Innovation (PARI), which is funded by the German Federal Ministry of Economic Cooperation and Development (BMZ) (Project No. 2014.0690.9). Bibiana Betancur-Corredor is funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) with project number: BE 7694/1-1. 6. Language of the dataset: English 7. Geographic location of data collection: Not applicable B DATA & FILE OVERVIEW 1. File List: One Excel file "Romero_etal_dataset_Productivity-effects-agroecol-practices.xlsx" containing information on agroecological practices by control and treatment groups for the meta-analysis. 2. Are there multiple versions of the dataset? No 3. Relationship between files: N/A 4. Additional related data collected that was not included in the current data package: The data pertaining the systematic review is not included in the current package. C SHARING/ACCESS INFORMATION 1. Was data derived from another source?: Yes. The data was draw from peer-reviewed articles identified through a systematic review. 2.

Description of methods used for collection/generation of data: Data was extracted using Microsoft Excel and the meta-analysis was performed in R-studio. For each pair of control-treatment, a description, yield data in kg ha-1, location, management practices and soil physicochemical properties were collected when available. The Köppen Geiger classification for the climatic zone and the USDA classification for soil texture was followed. Particular attention was given to the tillage method to ensure that both, control and treatment, apply the same method. For yield data provided in graphs, a Web Plot Digitizer was used to retrieve the data. The standard deviation was estimated when data of multiple years or standard errors was provided, as done in other studies. 2. Methods for processing the data: *Average yields is the mean yield with respect to the duration of the experiment *Percentage change was estimated with the following formula:((𝑦𝑖𝑒𝑙𝑑 𝑡𝑟𝑒𝑎𝑡𝑚𝑒𝑛𝑡 −𝑦𝑖𝑒𝑙𝑑 𝑐𝑜𝑛𝑡𝑟𝑜𝑙)/(𝑦𝑖𝑒𝑙𝑑 𝑐𝑜𝑛𝑡𝑟𝑜𝑙)) * 100 *Cells in black refers to missing values. Standard deviations or standard errors were not provided or not able to be estimated *Soil amendments (or application of compost/manure) was only done in treatment groups. Therefore, no data is given for control group. This refers to columns P *Compost application include residues or stover application *For articles that indicate basal application, the application rate was combined in the fertilizer application. *Tillage_type indicate the type of tillage applied in both treatment and control 3. Instrument- and/or software-specific information needed to interpret the data: R-studio 4. People involved in sample collection, processing, analysis and/or submission: Miriam E. Romero Antonio, Amy Faye, Bibiana Betancur-Corredor 5. Describe any quality-assurance procedures performed on the data: To examine the robustness of the results, we conducted a sensitivity analysis and a publication bias test. The rank correlation test indicated funnel plot asymmetry (p<0.0001) while the regression test did not show significant asymmetry (p=0.2530). These test results indicate that the findings were not influenced by publication bias. 6. Standards and calibration information: N/A 7.
