Methodological Guide for Agricultural Experiments on Small Farms

Conducting agricultural experiments on small plots requires clear methodology, control groups, and replication. This 2022 guide by Bio de PACA and partners supports market gardeners in designing reproducible, autonomous trials using data from 46 experiments (2018–2020) across 18 farms in Provence-Alpes-Côte d'Azur. It outlines an 8-step process: defining objectives, preparing the trial, selecting protocols, organizing data collection, implementing the trial with consistent varieties and ITK, documenting interventions, analyzing results against the control, and repeating over multiple years. Key success factors include using a control group, maintaining identical varieties, ensuring replication (2–3 repeats), and accounting for climatic and management variations. The guide emphasizes technical knowledge, proper tools, and long-term validation to ensure reliable outcomes.
