Every year, Tam Nong farmers planted about 100 hectares of vegetable, concentrated mainly in  Phu Hiep Commune, Phu Duc, Phu Thanh B. The vegetable helps Tam Nong farmers to overcome difficulties to enrich.

However, the output of vegetables is unstable, the price is also precarious. When cultivation area is expanded, price is dropped; when narrowing area the price is higher.

Starting from this reality, Mr. Tran Minh Tan - Deputy Secretary of the Youth Union of Phu Hiep Commune, determined to find a sustainable efficiency path for Tam Nong vegetables by building Phu Hiep special vegetable pickle trademark  to sell to tourists and consumers in the city, initially achieved positive results.
