Ensuring Vietnamese Tomatoes Success through Sustainable Farming Practices.

Updated: Aug 30, 2023

Vietnamese tomatoes hold a prominent position in the global agricultural and culinary scene, being one of the most widely cultivated and consumed fruits worldwide. Choose tomato varieties that are well-adapted to the local climate and growing conditions. Consider factors like disease resistance, fruit size, and growth habit to ensure optimal performance. Promote sustainable farming practices among farmers and the community through education and awareness programs. Encourage knowledge sharing and collaboration to foster a sustainable agricultural ecosystem.

Vietnamese Tomatoes Planting Seasons.


Tomatoes are a seasonal crop in Vietnam, and understanding the appropriate planting times is crucial to ensure optimal growth and development under favorable weather conditions, resulting in high yields and minimal pest impact.


Tomato Planting Seasons in Vietnam.

In Vietnam, there are three planting seasons for tomatoes:

  • Winter-Spring Season: Tomato seeds are sown from October to November in the Gregorian calendar, and the harvest time is approximately three months from the sowing date. Therefore, for the winter-spring season, tomatoes can be harvested around January to February.

  • Spring-Summer Season: Tomato seeds are sown from December to January in the Gregorian calendar.

  • Summer-Autumn Season: Seeds are sown in June and July in the Gregorian calendar, and the harvest can be expected around September to October.


Soil Preparation:


Choose a planting location far from industrial areas, hospitals, and factories to avoid water and air pollution. Opt for well-draining, loose, and fertile soil with a thick top layer and good water drainage.


Clean the planting area, remove plant residues from the previous season, and apply lime to the soil before tilling to control some soil-borne diseases.


Allow the soil to rest and dry for 7-10 days before planting. In the dry season, create planting rows 15-20 cm high and 30 cm apart, with a wide surface of 1.2 meters for double-row planting.


In the rainy season, create planting rows 25-30 cm high and 30 cm apart, with a wide surface of 90 cm for single-row planting. Use agricultural covering films to retain moisture, prevent nutrient leaching, control weeds, and minimize pests and diseases. By following these techniques and appropriate planting times, Vietnamese farmers can achieve successful tomato cultivation, ensuring healthy and bountiful tomato crops throughout the year.


Planting and Care Techniques for Tomatoes.


Planting Technique: Plant tomatoes in the cool afternoon, gently placing the seedlings without compacting the soil too tightly. After planting, water the seedlings immediately to maintain moisture. Reserve 5% of the seedlings of the right age for later planting between rows, making it convenient for subsequent care. Check and replant any dead seedlings 7-10 days after the initial planting.


Weed Control: Employ early weed prevention methods and maintain weed control until the tomato plants can effectively compete with weeds. Weed control should be implemented before flowering. Use mechanical and chemical methods to manage weed growth.

Watering: From planting until the seedlings are well-established, water 1-2 times per day. Afterward, adjust watering based on weather conditions and soil moisture, ensuring the soil remains about 60-70% moist. During flowering, tomatoes require more water, maintaining soil moisture at around 70-80%. During the rainy season, ensure proper drainage to avoid water logging in tomato fields.


Planting and Care Techniques for Tomatoes.

Hilling: 7-10 days after planting, perform hilling to create mounds around the plants. Around 20-25 days after planting, apply fertilizer and hill up the soil to prevent water stagnation between rows, promoting better root development. Remove diseased plants, diseased fruits, and pests. During the rainy season, prune lower leaves and older yellow leaves to improve air circulation and dispose of diseased leaves away from the planting area.


Supporting the Plants: When the tomato plants reach a height of 40-60 cm, create support structures (trellises) to evenly distribute the plants on the mounds. This makes it easier to care for and protect the plants from pests and diseases.


Pruning the Shoots: Timely prune new shoots that have grown to 3-5 cm to allow nutrients to concentrate on fruit development. Regularly remove ineffective side shoots. Break off the shoots by hand rather than using nails or scissors, as this may cause infections through wounds.


Leaf Pruning: Prune lower leaves and older yellow leaves to improve air circulation in the garden, especially in dense plantings prone to disease during the rainy season. However, during the dry season, leave lower leaves intact to provide shade and prevent sunscald.


Fruit Pruning: Limit each fruit cluster to 4-6 fruits, removing excess fruit to concentrate nutrients for larger and uniformly sized fruits with higher commercial value.


Topping: For tomato varieties with a long growth period and tall plants, topping (removing the tip of the main stem) can be done near the end of the harvest to encourage uniform fruit growth and concentrate the harvest.


Planting and Care Techniques for Tomatoes.
Sustainable farming practices play a crucial role in ensuring the success of tomato cultivation, promoting environmental conservation, and enhancing long-term agricultural viability. By incorporating these sustainable farming practices, tomato growers in Vietnam can achieve not only successful tomato yields but also contribute to a healthier environment, reduced ecological footprint, and long-term agricultural prosperity. Sustainable tomato cultivation ensures the well-being of both farmers and the ecosystem, fostering a more resilient and sustainable agricultural future.
