Tomatoes are a versatile and widely enjoyed fruit that can be grown in gardens or even in containers on balconies and patios. If you're eager to cultivate your delicious tomatoes, this comprehensive guide will take you through the step-by-step process, from selecting the right tomato varieties to harvesting your juicy, sun-ripened crop. Let's dive into the complete steps involved in tomato production.
Climate and Soil Requirements
Tomatoes are incredibly adaptable and can thrive in diverse soil types, including sandy to heavy clay. However, for optimal growth, it's recommended to cultivate tomatoes in well-drained soils such as sandy or red loam, enriched with ample organic matter and maintaining a pH level between 6.0 and 7.0.
Variety Selection:
Choose tomato varieties that suit your growing conditions and culinary preferences. Consider factors such as fruit size, color, taste, disease resistance, and intended use (e.g., slicing, canning, or cherry tomatoes).
Choose the best high-yield tomato seeds from Agriplex India
Start tomato seeds indoors, 6-8 weeks before the last expected frost date in your area. Fill seed trays or small pots with a well-draining seed starting mix. Plant the seeds at a depth of ¼ to ½ inch and moisten the soil. Place the trays/pots in a warm area with ample sunlight or use artificial grow lights for germination.
Transplanting
Once the tomato seedlings have developed several sets of true leaves and the risk of frost has passed, it's time to transplant them into larger containers or directly into the garden soil. Choose a sunny location with fertile, well-drained soil. If transplanting into containers, ensure they have sufficient drainage holes and are large enough to accommodate root growth.
Soil Preparation:
Prepare the soil before transplanting by removing weeds, loosening the soil, and incorporating organic matter, such as compost or well-rotted manure. Tomatoes prefer slightly acidic soil with a pH level between 6 and 7. Conduct a soil test to adjust the pH if necessary. Adequate soil preparation ensures optimal nutrient availability and drainage.
Planting and Spacing:
When planting your tomato seedlings, dig holes that are deep enough to bury the lower part of the stem, including the cotyledon leaves. Remove the lower leaves, leaving only the top few sets. Space the plants according to the specific variety's recommended spacing guidelines, typically around 18-24 inches apart. Firmly press the soil around the base of each plant for stability.
Watering and Fertilization:
Tomatoes require consistent moisture throughout their growing period. Water the plants deeply, providing about 1-1.5 inches of water per week, depending on weather conditions. Avoid overhead watering to minimize the risk of disease. Apply organic mulch around the plants to help retain moisture and reduce weed growth. Additionally, feed the tomatoes regularly with a balanced fertilizer, following package instructions, to ensure healthy growth and fruit production.
Nutrient Management in Tomato Crop
By implementing effective nutrient management practices, you can provide your tomato crops with the essential elements they need for optimal growth, health, and high yields
The nutrient requirement for hybrids is 200:250:250 kg of NPK per ha. 75 % of P (187.5 kg P which comes to 1172 kg of superphosphate) is applied as basal. The remaining quantity of 200:62.5:250 kg of NPK per ha is applied through fertigation. Every day irrigation should be given for one hour. Along with this, water-soluble fertilizers have to be given. This dose is split and given once in 3 days for the entire crop period through fertigation as detailed below.
Whitefly attack on tomatoes can result in chlorotic spots, yellowing, downward curling, drying of leaves, and serve as a vector for tomato leaf curl disease.
The borer larvae consume the inner content of the fruit by making circular holes on the surface and partially penetrating fruits to consume the inner contents.
Use Tapas Helic-O-lure with funnel trap at 6 per acre. Spray 2 ml of Plethora Insecticide mixed in 1 L of water. Spray Cigna Insecticide at 1.5 – 2 ml/L of water.
Pinworm (Tuta absoluta )
Tuta absoluta infestation in tomatoes can cause leaf and stem mining, along with the presence of pinholes on fruits.
The presence of serpentine mines on leaves and subsequent drying and dropping of leaves are common symptoms of damage caused by the Serpentine leaf miner (Liriomyza trifolii) in tomato plants.
Mealybug infestation on tomatoes causes the presence of white, cottony masses on leaves, stems, and fruit, as well as stunted growth and yellowing of leaves.
Thrips feeding on tomato plants result in crinkling and curling of leaves due to sap extraction, giving a silvery or bronze appearance. Additionally, affected flower buds become brittle and eventually drop off.
Red spider mite infestation on tomato plants leads to affected leaves turning reddish brown and bronzy. In severe cases, the presence of larvae results in silken webbing on the leaves, causing them to wither and dry. The infestation can also impact flower and fruit formation
Damping off in tomatoes occurs in two stages: pre-emergence and post-emergence. In the pre-emergence phase, seedlings are killed just before they reach the soil surface, resulting in the complete rotting of the seedlings. In the post-emergence phase, the infection targets the young tissues at the collar level, causing them to become soft, and water-soaked, and leading to seedling collapse or toppling over.
Spots on leaves, stems, and fruits Wilting of leaves and shoots, cracks and cankers with slimy bacterial ooze, and small water-soaked spots with white halos on fruits that become raised, tan-colored, and rough in the center.

Early Blight
Small, black lesions on older foliage, which enlarge and develop concentric rings in a bull's eye pattern.Yellowing of surrounding tissue and potential foliage loss in high temperature and humidity conditions.
Small, brown, water-soaked circular spots with a yellowish halo on infected leaves, potentially leading to defoliation on older plants.Water-soaked spots on green fruits that enlarge into raised, irregular, light brown lesions with a rough, scabby surface; ripe fruits are unaffected.

Bacterial Wilt
Rapid and complete wilting of mature plants, with lower leaves potentially dropping before wilting occurs. The presence of bacterial ooze appears as a white streak when infected plant parts are cut and immersed in clear water.
Veinlet clearing and leaf chlorosis, leading to wilting and death of younger leaves, progressing to complete plant wilting within days. Yellowing of lower leaves, subsequent leaf wilting, browning of the vascular system, stunted growth, and plant death.
The ideal time to harvest tomatoes varies depending on the specific variety and intended use. Tomato plants generally start producing fruits around two to three months after planting, and it takes another four to six weeks for the fruits to ripen fully.
The yielding starts after 50 to 60 days of sowing. The picking can be done every 10 to 15 days intervals from the date of first picking. A farmer can go for picking about five times until the last harvest.
