Yield sensors are an emblematic technology for precision agriculture but few studies are available on the level of adoption of this technology in France. The purpose of this paper is to assess this level in France, to identify the main use cases and to explore the obstacles that limit adoption. A qualitative survey was designed based on key stakeholders in the yield sensor market. Out of 46 stakeholders contacted, 24 responded to semi-structured interviews (7 manufacturers, 5 service providers, and 12 end-users). The equipment usage rate for French farmers was estimated at 22%. The majority of equipped farmers used yield sensors only for real-time visualisation during the harvest. Only a few of them (<25%) are producing and using yield maps. The five main obstacles were identified involving different stakeholders of the value chain.
