1. What variety is the yellow-fleshed sweet potato?

Yellow-fleshed sweet potatoes in Vietnam are commonly referred to as “Japanese sweet potatoes”, as the variety originally comes from Japan. However, thanks to the favorable climate and soil conditions in the Central Highlands of Vietnam, this variety thrives exceptionally well, delivering high yields and, notably, a better taste compared to other growing regions.

This sweet potato variety has a growth cycle of 4 to 7 months, depending on the specific cultivation area and the farming practices used by local growers.

Identifying characteristics of this sweet potato variety:

• The skin of the tuber is pink to light red, while the flesh inside is yellow.

• This variety is typically divided into two types: “Sình” and “Đồi”.

“Sình” type:

• Grown in areas with high moisture and heavy, compact soil (clay-like).

• The flesh texture is more dense and moist, similar to the soil where it grows.

“Đồi” type:

• Cultivated in dry, red basalt soil in upland or hilly areas.

• The tubers are more well-ventilated, with a slightly different skin color compared to the “Sình” type.

2.Which region in Vietnam produces the best yellow-fleshed sweet potatoes?

In Vietnam, sweet potatoes from almost every region have great taste, but each growing area offers its own unique flavor profile.

Currently, international buyers frequently place orders for export-grade yellow-fleshed sweet potatoes from Vietnam. Among the various regions, the Central Highlands is particularly favored — especially Lam Dong Province, which stands out as the strongest producer.

Sweet potatoes from this area are known for their superior taste, and the region also offers high yields, making it well-suited to meet the demands of global markets.

Key factors why international partners choose the Central Highlands – especially Lam Dong – as a sourcing region for yellow-fleshed sweet potatoes:

• Large land availability ensures high production capacity and stable supply.

• Fertile basalt soil is ideal for growing sweet potatoes with excellent quality.

• The region has a suitable climate, which contributes to better tuber quality and longer shelf life.

• Experienced local farmers with strong expertise in sweet potato cultivation.
