Many farmers in the Mekong Delta are expanding their fields to cultivate Japanese purple sweet potato because of enormous increase in demand for export.
Huynh Van Quan, Deputy Director of Tan Thanh Cooperative in Vinh Long Province, said that for days the price of Japanese purple sweet potato has continued to rise.
The agricultural produce fetches around VND800,000 (US$38) per quintal which brings high profits for farmers.
Floods in some districts in the Mekong Delta have caused decrease in cultivation but there is still an increase in export demand.
