Potato (Solanum tuberosum L.) is known for its efficiency in converting resources into high-quality food, which can aid in poverty reduction. However, the potato yield in Rwanda has been declining, leading to farmer dissatisfaction with trading terms and a reliance on low prices in the value chain. Moreover, the use of good agricultural practices (GAPs) has not been adopted wholly, and their contribution to yield has still not been established. Correspondingly, the driving force in the adoption scenario of GAPs and the effects of adoption have remained unclear.
