Sweet potato is a strategic root crop in Oceania: A synthesis of the past research and future direction

Sweet potato is an important food, industrial, and pharmaceutical crop worldwide highly adapted to adverse ranges of agroclimatic conditions, making it one the strategic crops under climate change. Despite importance, sustainable production continues be issue because pressure put on land, decline in soil fertility, buildup pests diseases, no standardized practices. Production mechanized temperate regions, whereas, tropics, still a subsistence confined farming systems. These issues are compounded by lack generically agronomically improved genotypes wider agroecological zones with adaptive tolerance existing new stresses. In recent past, significant progress has been made worldwide; however, outcomes tend locality-specific, cannot extrapolated, needing decentralization current approaches. This review points out that critical Oceania region its ability grow conditions can produce reasonable yield. The paper emphasize trends emerging modern technology used efficiently improve enhance traits agronomic importance adaptivity. addition, land use plans, systems, cultural practices need changed for production. these further strengthened pointing alternative strategies, e.g., using organic matter as relatively cheap readily available source nutrients compared inorganic fertilizers.
