**6. Constraints to sweet potato production**

Farmers' low productivity in sweet potato is attributable to many constraints: abiotic, biotic, management, and socio-economic constraints.

#### **6.1 Abiotic constraints**

Low and declining soil fertility, excessive soil moisture due to poor drainage, soil salinity, poor soil aeration due to soil compaction, inadequate rainfall during the growing season, floods, drought, and high temperature [2].
