High turnover among Tanzania's agro-dealers linked to farmer fertilizer adoption, study finds
A new study in the American Journal of Agricultural Economics examined Tanzania's agro-dealer sector and found that frequent turnover affects farmer perceptions of product quality, with implications for market functioning.
Smallholder farmers in sub-Saharan Africa adopt agricultural inputs like fertilizer at low rates, contributing to low productivity. Previous research points to insufficient information and distrust in product quality as reasons. The new study, from University of Illinois Urbana-Champaign researchers, looked at the agricultural marketplace in Tanzania. It found that frequent turnover among local agro-dealers affects how farmers perceive product quality and has broader market implications. The evidence summary does not detail the size of the effect or the study's methods.
