Growing lotus for its rhizomes in rice paddies provides a good income.

To increase income from the same area of ​​rice land, for many years, Mr. Dinh Duc Trung, from Bung Trong hamlet, Tai Van commune, Can Tho city, has been growing lotus plants for their rhizomes in his rice fields (one rice crop / one lotus crop). Growing lotus for rhizomes has low investment costs, a stable market, and also contributes to improving the ecological environment, helping the rice plants grow well in the following season.

Mr. Dinh Duc Trung, from Bung Trong hamlet, Tai Van commune, Can Tho city, is harvesting lotus roots to prepare for sale to traders.

According to Mr. Trung, compared to lotus grown for seeds or flowers, lotus grown for rhizomes has a shorter harvesting time and can be harvested continuously for many months. By rotating lotus cultivation with rice fields, the lotus grows well, and when the lotus season ends, the rice crop is less susceptible to disease and yields a good harvest. Mr. Trung has been rotating lotus cultivation for rhizomes in his rice fields for 3 years, covering a total area of ​​2.8 hectares.

From planting to harvesting, lotus plants take 55-60 days. After the first harvest, harvesting continues every 2-3 days, with an estimated yield of over 250kg per harvest per 2.8 hectares (10-12 harvests per month).

In the first six months of the year, Can Tho City saw the establishment of 2,448 new businesses.(CT) - According to the Can Tho City Department of Finance, in the first six months of 2026, the city saw the establishment of 2,448 new businesses with a total registered capital of over 12,192 billion VND, an increase of 14.66% in number but a decrease of 5.6% in registered capital compared to the same period last year; 601 businesses resumed operations, an increase of 35.06%; 324 businesses were dissolved, an increase of 77.05% compared to the same period last year; and 1,104 businesses temporarily ceased operations, a decrease of 0.18% compared to the same period in 2025.

With 2.8 hectares dedicated to lotus cultivation for rhizomes, and selling them at prices ranging from 18,000 to 35,000 VND/kg (depending on the time of year), Mr. Trung earns an average of over 30 million VND per month, a much higher profit compared to rice cultivation. After harvesting the rhizomes for one year, the lotus plants are removed and replanted to ensure a high yield of rhizomes. Typically, after the lotus season ends, Mr. Trung plants the winter-spring rice crop, as this is a high-yielding crop with good prices. In addition to lotus for rhizomes, he also raises freshwater fish such as tilapia, carp, and catfish in the lotus fields. The fish are harvested after the lotus season, yielding an estimated 2 tons and generating over 40 million VND per year.

Over the past three years, Mr. Trung has been rotating lotus cultivation in his rice fields to reduce seasonal investment costs. He has nurtured the lotus seedlings himself, ensuring a clear origin and minimizing pest and disease attacks.

According to Mr. Trung's experience, lotus seedlings, after being transplanted from the rice paddy, should be planted in a leveled field. To prevent breakage, the seedlings should be planted at a moderate depth (avoiding shallow or deep planting); the planting distance should be 1.5m x 2m/plant, and 1.5-2m from the edge of the field. After planting, maintain a water level of 20-25cm in the lotus field to help the lotus quickly take root and gradually increase the water level as the plant grows; a water level of 40-50cm in the lotus field will help the plant grow well. Lotus grown in rice paddy does not require much fertilizer; fertilize once every two months, with an amount of about 200kg/2.8ha (using urea, phosphorus, and potassium fertilizers). In addition, spray biological pesticides on the lotus field every three months to prevent pests from attacking the lotus leaves, such as green caterpillars (leaf-eating caterpillars); thrips (sucking sap and causing leaves to curl and not unfold); and red spider mites.

According to Danh Tan Quyen, Chairman of the Farmers' Association of Tai Van commune, the model of rotating lotus cultivation for rhizomes in rice fields has been adopted by many farmers in the commune in recent years, with Mr. Dinh Duc Trung's household being a prime example. Currently, the area planted with lotus for rhizomes in the commune is estimated at 8 hectares, considered a model that opens up opportunities to increase farmers' income. If the production area is planned and consumption is linked, the lotus cultivation model will become a sustainable agricultural model, contributing to the development of the rural economy in the locality in the future. The Farmers' Association of the commune will promote and encourage members to rotate lotus cultivation for rhizomes in rice fields to help increase members' income on the same production land area and create more jobs for rural laborers.
