This type of vegetable only grows underground and is effective for livestock farming.

Every year, right after harvesting the summer-autumn rice crop, Ms. Nguyen Thi Luu's family in Hamlet 7, Quynh Yen Commune quickly plants more than 1 sao of winter-spring water spinach. Ms. Luu said that the water spinach is cut into short pieces, spread evenly across the field, and lightly pounded with thin wooden boards so that the stems cling to the soil so they can quickly take root and germinate.

This is a type of vegetable that likes moisture, suitable for cold weather, so after about 45 - 50 days from planting, the first harvest is ready, then nitrogen and phosphorus fertilization is applied to help the vegetables continue to grow. Each crop, Ms. Luu harvests 2 batches, bringing in an income of 2.5 - 3 million VND/sao.

For Ms. Ho Thi Lien in Hamlet 6, water spinach is the family’s main crop in the winter. Every year, she regularly grows more than 3 sao of water spinach. This vegetable has a high germination rate in the stem and grows at a fairly high density.

Thanks to her many years of experience, Ms. Lien's vegetable growing area has always been growing well. Currently in the harvest season, every day she cuts nearly 100 bunches of vegetables to sell at the markets at a price of 2,000 - 2,500 VND/bunch, earning about 200,000 VND/day.

This winter crop, Quynh Yen commune planted 20 hectares of water spinach, mainly concentrated in hamlets 5, 6, 7, 8 and hamlet 9. Water spinach is a soft, spongy plant, chosen by many farmers as daily green food for livestock and poultry. Therefore, farmers sell all the harvest.

For good vegetable fields with high productivity, growers can earn about 4 million VND/sao.
