People here grow potatoes mainly in the winter-spring crop, starting from the 11th lunar month, people start planting and harvest at the beginning of the 3rd lunar month.

According to Ms. Tho, growing this sweet potato does not require much care, but mainly fertilizing, stimulating root and tuber growth, and limiting the growth of vines and leaves because experience in growing this plant shows that "good vines harm tubers".

Before planting, her family plowed the soil, sprinkled lime powder to prevent pathogens, and mixed the soil with manure to increase nutrition. When planting potatoes, they had to be mounded into ridges to ensure drainage and avoid the tubers rotting and being eaten by worms.

Currently, sweet potatoes have become a specialty because they are a healthy food, good for the body, so they are favored by consumers, so the output is also easy to sell, with the current price depending on the size of the potato, type 1 costs 15,000 VND/kg, small type from 8-12 thousand VND/kg, each sao after deducting costs also gives people an income of 5 million VND.

Next to the field, Ms. Tran Thi Sen's family is also harvesting sweet potatoes. Ms. Sen said: Her family has 1.5 sao of rice fields but cannot control the water source, so for the past 5 years, her family has switched to growing sweet potatoes.

Sweet potatoes are easy to grow and have few pests and diseases, but to make the plants produce many tubers and produce uniform tubers, during the growing process, her family is careful in every step from choosing the seeds, preparing the soil to fertilizing according to each stage of the plant's development. The difference of the sweet potato specialty in this region is that the seeds are kept by the people from one season to the next, not brought from other regions. At the end of each season, people take a small amount of seeds to plant in their home gardens. When the season comes, they cut off the tops of the seeds and plant them in the fields. About 15 days after planting, when the potatoes take root and begin to develop, they are fertilized with phosphorus, potassium and decomposed manure to help the plants grow and develop. When harvesting, in addition to choosing a sunny day, when digging, it is necessary to avoid scratching the potatoes so that they can be preserved for a long time and have a higher selling price.

Mr. Nguyen Sy Thang, Vice Chairman of the People's Committee of Phuc Son Commune, said: Previously, sweet potatoes were mainly used as animal feed, but in recent years, it has become a crop that provides the main source of income from tubers, contributing to increasing income and improving the lives of farmers.
