The study evaluates the impact of a pilot farmer‑field‑school program on potato farmers’ knowledge of integrated pest management practices in Peru. Using survey data, the authors employ regression analysis and propensity score matching to compare participants with a comparable non‑participant group. Results show that participants have significantly greater IPM knowledge and suggest that this knowledge can substantially increase potato productivity.
Using survey data from Peru, this article evaluates the impact of a pilot farmer‐field‐school (FFS) program on farmers' knowledge of integrated pest management (IPM) practices related to potato cultivation. We use both regression analysis controlling for participation and a propensity score matching approach to create a comparison group similar to the FFS participants in observable characteristics. Results are robust across the two approaches as well as with different matching methods. We find that farmers who participate in the program have significantly more knowledge about IPM practices than those in the nonparticipant comparison group. We also find suggestive evidence that improved knowledge about IPM practices has the potential to significantly improve productivity in potato production.
