This study documented the popularity, production constraints, pests and diseases, farmers’ perceptions on the severity of biotic constraints and the impact of related crop losses on household food securi...
It is increasingly becoming important to understand relationships between temperature (manifested at different altitude levels) and sweet potato insect pest characteristics in light of temperature changes as a result of global warming. Field surveys were conducted in Kabale district of Uganda alo...
