Farming & Cultivation Guide — Tomato Seeds – Katrina
Complete step-by-step agronomic guide for optimal crop management, disease resistance, and premium produce quality.
🌾 Soil Preparation & Field Prep
Proper land preparation ensures uniform seedling emergence and robust root anchorage.
🌱 Ideal Soil Type & pH
Well-drained loamy to sandy-loam soils with pH 6.0–7.0 and good organic matter content. Heavy clay soils should be avoided due to poor drainage and waterlogging susceptibility.
✨ Core Advantage
Deep, fertile, well-aerated soil ensures strong root development, uniform nutrient uptake, and healthy vegetative growth essential for continuous fruit production.
- 1
Deep summer ploughing to 25–30 cm followed by 2–3 cross-harrowings for fine tilth and weed elimination.
- 2
Field leveling and formation of drainage channels to prevent water stagnation, especially in Kharif season.
- 3
Incorporate 8–10 tonnes per acre of well-decomposed FYM or compost during final harrowing for improved soil structure and moisture retention.
- 4
Conduct soil test and amend with gypsum (50 kg/acre) in alkaline soils or sulfur (25 kg/acre) in acidic soils to maintain pH within 6.0–7.0 range.
🌱 Sowing Time & Method
Precise seed rate and spacing maximize light interception and canopy development.
| Parameter | Recommendation | Agronomic Importance |
|---|---|---|
| Sowing Window | Kharif: June–July | Rabi: October–November | Summer: February–March (under shade net/protection) | Aligns crop cycle with favorable temperature and avoids peak ToLCV pressure during extreme summer monsoon periods |
| Seed Rate | 250–300 g per Acre (Transplanted nursery method) | Ensures adequate plant population of 25,000–30,000 plants per acre with strong healthy seedlings |
| Spacing | 60 cm (row-to-row) x 45 cm (plant-to-plant) | Promotes optimal canopy development, air circulation, and sunlight penetration for disease management and fruit quality |
| Sowing / Transplanting Depth | Sow seeds at 0.5–1.0 cm depth in nursery; transplant seedlings at same depth as in nursery plug trays | Optimal depth ensures uniform germination, prevents damping-off, and promotes adventitious root development at base |
💧 Irrigation & Water Management
Adequate moisture regulation supports strong vegetative and reproductive growth.
☀️ Water Requirement Profile
Tomato is moderately sensitive to water stress, particularly during flowering and fruit set stages. Drip irrigation is highly recommended with 3–4 mm water applied per event. Maintaining soil moisture at 70–80% field capacity ensures uniform fruit development and prevents physiological disorders like blossom-end rot and sunscald.
🌦️ Soil Moisture Management
In rainfed situations, employ mulching with straw or black polyethylene film to conserve soil moisture and regulate soil temperature. Construct wide drainage channels between beds to safely evacuate excess monsoon rainfall and prevent root rot conditions.
- ✓
First irrigation immediately after transplanting (within 6 hours) to reduce seedling stress and promote rapid root establishment.
- ✓
Vegetative phase: Light irrigation at 3–4 day intervals during summer and 5–7 day intervals during Rabi/Kharif to encourage deep root growth.
- ✓
Critical stage — Flowering and Fruit Setting: Maintain consistent moisture without waterlogging; intermittent stress at this stage causes flower drop and misshapen fruits.
- ✓
Pre-harvest: Reduce irrigation frequency 7–10 days before last picking to improve fruit firmness, color development, and post-harvest shelf life.
🧪 Fertilizer & Nutrition Management
Balanced crop nutrition supports robust plant structure and premium produce quality.
| Nutrient | Recommended Dose (per Acre) | Application Method & Timing |
|---|---|---|
| Nitrogen (N) | 80–100 kg/acre (as Urea 46-0-0 @ 174–217 kg/acre) | 50% basal at transplanting; remaining 50% split into two equal top-dressings at 20 DAT and 40 DAT |
| Phosphorus (P2O5) | 50–60 kg/acre (as DAP 18-46-0 @ 109–130 kg/acre) | 100% basal application mixed thoroughly with soil during final land preparation |
| Potash (K2O) | 40–50 kg/acre (as MOP 0-0-60 @ 67–83 kg/acre) | 50% basal at transplanting; remaining 50% applied at 40 DAT to support fruit development and disease resistance |
🌿 Interculture & Weed Management
Timely weed control ensures optimal nutrient and moisture availability for crop seedlings.
-
1
First Weeding & Hoeing: Perform shallow hoeing at 10–12 DAT to control early weed flush and improve soil aeration. Avoid deep hoeing near plant base to prevent root injury. Maintain weed-free condition during first 30 days for optimal plant establishment.
-
2
Second Weeding & Earthing-Up: Carry out second weeding at 25–30 DAT along with light earthing-up around plant bases to support stems, cover adventitious roots, and improve moisture conservation during hot weather.
-
3
Staking and Suckering: Begin staking/support at 20–25 DAT using bamboo stakes or string trellis system. Remove lateral suckers below first flower cluster up to 4th cluster (single-stem training) to direct nutrition toward fruit development and improve airflow within canopy. Apply straw or black mulch between rows to suppress weeds and retain moisture.
🛡️ Pest & Disease Management
Proactive crop monitoring and integrated management ensure healthy crop development.
🐛 Insect Pest Management
- Whitefly (Bemisia tabaci): Symptoms include yellowing, curling of upper leaves and sooty mold deposition. Control: Yellow sticky traps @ 10/acre; spray Imidacloprid 17.8% SL @ 100 ml/acre or Thiamethoxam 25% WG @ 50 g/acre. Rotate with Afidopyropen 50% WG @ 100 g/acre for resistance management.
- Fruit Borer (Helicoverpa armigera): Symptoms include bore holes on fruits with frass exudation and internal feeding damage. Control: Install pheromone traps @ 10/acre for monitoring; spray Chlorantraniliprole 18.5% SC @ 70 ml/acre or Spinetoram 11.7% WS @ 60 ml/acre. Apply Bt cysts @ 250 g/acre as preventive measure.
- Leaf Miner (Liriomyza trifolii): Symptoms appear as winding whitish tunnels or mines within leaf tissue reducing photosynthetic area. Control: Spray Indoxacarb 14.5% SC @ 70 ml/acre or Cartap hydrochloride 50% WP @ 600 g/acre. Remove and destroy heavily infested leaves promptly.
🔬 Disease Control
- Tomato Leaf Curl Virus (ToLCV): Symptoms include upward curling of leaves, yellowing, stunting, and reduced flowering. Vector-borne by whiteflies. Control: Use virus-free certified seeds and resistant hybrids like Katrina. Install silver polyethylene mulch @ 40 m/acre to repel whiteflies. Spray Neem oil 3% @ 3 ml/liter at 10-day intervals. Rogue and destroy infected plants immediately.
- Bacterial Wilt (Ralstonia solanacearum): Symptoms include sudden wilting of one side of plant, brown vascular discoloration, and bacterial ooze from cut stem. Control: Practice 3-year crop rotation with non-Solanaceous crops. drench soil with Streptocycline 50 ppm @ 4 liters/plant at 15 DAT. Apply Trichoderma viride @ 5 kg/acre mixed with FYM as soil application for biocontrol.
- Early Blight (Alternaria solani): Symptoms present as concentric ring spots on lower leaves progressing upward, leading to defoliation and fruit sunscald. Control: Spray Mancozeb 75% WP @ 250 g/acre or Chlorothalonil 50% WP @ 150 g/acre at 10-day intervals starting from fruit setting stage. Ensure proper spacing and pruning for canopy airflow.
