Evaluation of adoption potential of modern technologies in potato value chain by smallholder farmers in Kenya: Nyandarua County pilot case study.

In Kenya, smallholder potato farmers endeavor to increase their production through various approaches, most commonly by expanding areas under production and repeatedly planting potato on the same site, with the latter resulting in build-up of diseases. Compounded with limited access to options to improve productivity, these farmers yield less than 10 t ha, much below realistic yields of 20 to 30 t ha. In an attempt to address these constraints, a study in the framework of the pilot project Potato Initiative Africa lead by International Potato Center (CIP) evaluated modern interventions to improve yields and reduce harvest and post-harvest losses along the production chain.
