Bac Ha district in Vietnam has successfully cultivated kale in highland communes like Lung Phinh, finding it to be a high-value crop. The district has encouraged farmers to convert inefficient arable land to kale cultivation, offering support and promising profits of nearly 200 million VND per hectare. The kale model has proven effective, with significant additional income for local farmers. The government and Agricultural Service Center are providing seedlings and technical guidance, while farmers cover costs and labor. Kale is sold to agricultural extension officers and traders at a stable price of 20,000 VND/kg, offering a higher selling price compared to other vegetables and grains.
