Tomato cultivation involves growing seeds for the production of tomato fruits. It is a warm-season crop that thrives at an average temperature of 21°C to 23°C. When managed properly, tomato farming can make you millions in Nigeria. You can grow tomatoes in gardens, containers, greenhouses, or open fields. Depending on the variety, harvesting takes about 60 to 80 days after sowing.
Tomato Cultivation in Nigeria
In the past, tomato farming was mainly practiced in northern Nigeria. However, due to modern irrigation systems and greenhouse technologies, tomato cultivation is now possible in southern parts of the country. This expansion has created more opportunities for farmers nationwide.
Types of Tomatoes
Tomatoes are classified into two main types: determinate and indeterminate.
1. Determinate Tomatoes
Determinate tomatoes grow to a fixed size and produce all their fruits within a short period. They do not need staking or caging, making them ideal for small gardens and container farming. These varieties are perfect for canning, sauces, and paste production.
2. Indeterminate Tomatoes
Indeterminate tomatoes grow continuously throughout the season. They produce fruits gradually and require staking for support. Because of their continuous growth, they are best suited for large gardens and commercial farming.
How to Start Tomato Farming in Nigeria
1. Select the Right Seeds
Your journey to success begins with high-quality seeds. Popular hybrid varieties include Platinum F1, Maxim F1, Cobra 26 F1, and Rio-Grande. Avoid using old or crude seed varieties as they reduce yield. Choosing quality seeds can increase productivity up to three times more than traditional methods.
2. Prepare the Nursery
Start by preparing a nursery bed where your seeds can germinate. You may grow them indoors or outdoors. Once the seedlings develop roots and leaves, transplant them to the main field.
3. Sowing and Germination
Use seedling trays or coconut husk for better results. If using soil, apply pesticides 5–6 days before planting to prevent pests and diseases. Water the seedlings regularly and ensure they are healthy before transplanting.

4. Site Selection and Soil Preparation
Choose a sunny area because tomatoes need at least six hours of sunlight daily. They grow well in slightly acidic soil with a pH between 6.0 and 7.0. Ensure the soil is well-drained and rich in organic matter. Apply manure or fertilizer 20 days before transplanting to improve soil fertility.
5. Transplanting the Seedlings
Seedlings aged 24–30 days and 8–10 inches tall are ready for transplanting. Water the soil before and after transplanting. For protection, dip the roots in a mild pesticide solution to prevent fungal diseases.
6. Watering and Irrigation
Water is essential in tomato cultivation. Relying only on rainfall is outdated. Instead, use drip irrigation, which provides steady water to the plant roots and prevents leaf diseases. It also helps conserve up to 80% of water compared to other methods.
7. Protect and Weed Regularly
Weed control and pest management are critical. Protect your plants from diseases like bacterial wilt, leaf spot, and root rot. Also, control insects such as leaf miners and thrips. Regular weeding improves air circulation and reduces disease risk.
8. Staking Tomatoes
Staking provides support for your plants. You can use single or multiple staking methods. Tie the stems gently to the stakes and prune excess leaves. Proper staking improves fruit size, quality, and air circulation.
9. Fertilizer Application
Apply fertilizers based on soil test results. Avoid excessive nitrogen, as it leads to leafy growth with few fruits. Use fertilizers rich in phosphorus, potassium, and calcium. Bone meal and organic compost are excellent for root development.
10. Harvesting
Tomatoes are ready for harvest when they turn red and firm. You can twist them gently from the stem or cut them with scissors. Some farmers harvest slightly before full ripening to prevent cracking and spoilage.
11. Pest and Disease Control
Inspect your plants daily. Remove infected leaves or plants immediately. Apply organic insecticides when necessary. Always choose disease-resistant tomato varieties to reduce losses.
12. Marketing Your Tomatoes
Plan your marketing before harvest. Identify buyers such as restaurants, food vendors, and processing companies. Visit local markets to compare prices and find profitable outlets for bulk sales.
13. Storing Tomatoes
Tomatoes are perishable, so store them carefully. Keep ripe tomatoes at 10–15°C with 85–95% humidity. Avoid refrigeration, as it can reduce flavor and texture. Use plastic crates for better air circulation during storage.
Health Benefits of Tomatoes
Tomatoes offer numerous health benefits, including:
-
They contain antioxidants that improve vision.
-
Their fiber content aids digestion.
-
The high water content prevents constipation.
-
Lycopene protects against heart disease and prostate cancer.
-
They are rich in vitamins C and A, which strengthen immunity.
Conclusion
Tomato farming is one of Nigeria’s most profitable agribusinesses. With the right knowledge and techniques, anyone can grow tomatoes and earn steady income year-round. Beyond profits, tomatoes play a vital role in a balanced diet by providing essential nutrients, minerals, and vitamins.
