Before
This randomized control trial (RCT) will compare the impact of Farmer Field School (FFS) to a control condition that receives no intervention. After listing and screening by the implementing partner, the research team made a randomized allocation on the farmer level to the treatment or control condition and selected a sample for inclusion in the survey component. The survey treatment and control sub-samples were intended to be balanced between arms on gender.
Baseline process: The sampling lists for the survey were sent to the survey team for a field survey without disclosure of the treatment allocation. During the field survey, farmers consented with recorded verbal or written documentation. At the end of the field survey in each area, lists of the farmers to be treated in each area will bewere sent to the implementation organization in order to begin intervention activities. Due to delays in receipt of the sampling lists, an in-person baseline survey was not conducted in 3 out of the initially 4 planned sites in Anosy. Due to further delays in implementation in these 3 areas, these were dropped from evaluation, resulting in a reduced sample size and the evaluation taking place in 10 FFS sites (see details below). Our primary outcomes will be based on intention to treat analysis with key baseline covariates included to improve precision.
Due to the reported absence of an intervention in at least one area, we will undertake a per protocol analysis using the randomization as an instrumental variable as recommended for pragmatic trials with incomplete adherence. Per protocol is defined as attending any session at the farmer field school.

Due to the reported absence of an intervention on the day prior to field work in at least one area, we will undertake a per protocol analysis using the randomization assignment as an instrumental variable as recommended for pragmatic trials with incomplete adherence. Per protocol is defined as attending any session at the farmer field school.
