Constraints for potato production in the tropics
Potato tuber yields in the tropics are extremely low compared to those of temperate zones. The low yields merely reflect the inability of the current technology to overcome soil and environmental constraints. Given the various constraints affecting potato production in the tropics, few viable soil and crop management options remain. This paper reviews key constraints for potato production, assesses the impact of indigenous and/or adapted technology in managing them, and examines basic relationships describing productivity changes as management takes place. The overall intent of this paper is to outline the scientific basis for developing management strategies to sustain and improve potato production in the tropics.
