Key Features of Cauliflower Cultivation

Climate and Soil Requirements

• Cool-season crop; optimum temperature: 15–20°C.
• High temperatures cause poor curd formation.
• Sensitive to extreme heat and frost damage.
• Best soil type: loamy soil rich in organic matter.
• Soil pH between 6.0 to 7.0 suitable.
• Requires well-drained soil to avoid root rots.
• Excess saline and alkaline soils are not suitable.
• Adequate moisture is essential for good curd growth.
• Early varieties need slightly higher temperatures than late ones.
• Uniform climate helps in compact white curd formation.

Land Preparation

• The field should be ploughed 3–4 times for fine tilth.
• Remove weeds, stones, and stubbles from the field.
• Prepare raised beds or ridges for good drainage.
• Incorporate farmyard manure or compost before sowing.
• Level the land for uniform irrigation.
• Deep ploughing ensures removal of soil pests.
• Add lime or gypsum if soil is too acidic/alkaline.
• Proper leveling prevents waterlogging.
• Prepare a nursery bed for seed raising.
• Mulching helps conserve soil moisture.

High-Yielding and Hybrid Seed Selection

• Choose certified and disease-free seeds.
• Hybrid seeds ensure higher yield and uniform curds.
• Select variety as per season (early, mid, late).
• Improved varieties: Pusa Snowball, Pant Gobhi, Hazipur Local.
• Hybrid types suitable for export purposes.
• Seeds should be selected based on climatic suitability.
• Late varieties have better storage quality.
• Early types mature in 60–80 days.
• Late varieties take 120–150 days.
• Seed cost is higher for hybrids but ensures more profit.

Seed Treatment

• Treat seeds with fungicide (Captan/Thiram @ 2g/kg).
• Bio-fungicides like Trichoderma for eco-safe protection.
• Treat with hot water at 50°C for 30 minutes.
• Seed priming helps in faster germination.
• Prevents seed-borne diseases like damping off.
• Use Rhizobacteria for improved soil health.
• Neem seed extract for bio-protection.
• Seed coating with micronutrients enhances vigor.
• Store treated seeds in cool and dry places.
• Always test germination percentage before sowing.

Sowing and Planting Methods

• Seeds are sown in nursery beds first.
• Transplant seedlings after 3–4 weeks.
• Maintain spacing: 45 x 45 cm for early, 60 x 60 cm for late varieties.
• Line sowing ensures better intercultural operations.
• Planting depth: cover seed lightly with soil.
• Water lightly after sowing.
• Staggered sowing helps in continuous supply.
• Direct sowing is not common, but possible in some regions.
• Avoid overcrowding to reduce disease spread.
• Proper spacing ensures good curd development.

Nutrient and Fertilizer Management

• Requires heavy manuring for healthy growth.
• Apply FYM @ 20–25 tons/ha during land prep.
• Apply N: P: K @ 120:80:60 kg/ha.
• Calcium is important for white curd formation.
• Apply Nitrogen in split doses for best effect.
• Foliar spray of micronutrients improves yield.
• Boron deficiency causes hollow stem; apply accordingly.
• Use bio-fertilizers to maintain soil fertility.
• Avoid excess nitrogen to prevent loose curds.
• Balanced nutrition ensures better quality produce.

Irrigation and Water Management

• Provide light irrigation immediately after sowing.
• Subsequent irrigation every 7–10 days.
• Critical stages: curd initiation and development.
• Avoid flood irrigation to prevent root decay.
• Use drip irrigation for water saving.
• Furrow irrigation is also suitable.
• Excessive moisture spoils crop quality.
• Protect from waterlogging during the rainy season.
• Ensure uniform supply of moisture.
• Mulching reduces evaporation losses.

Intercultural Operations

• Regular weeding and hoeing required.
• Mulching to conserve moisture and suppress weeds.
• Earthing-up around the plant base prevents lodging.
• Gap filling of missing seedlings required.
• Hand weeding at 20–25 days after planting.
• Hoeing improves soil aeration.
• Use pre-emergence herbicides like Pendimethalin for weed control.
• Remove diseased plants immediately.
• Maintain plant spacing.
• Keep nursery weed-free for healthy seedlings.

Pest Management

• Common pests: aphids, diamondback moth, cutworms, cabbage butterfly.
• Spray neem oil for eco-friendly pest control.
• Use pheromone traps for moth insects.
• Release biocontrol agents like Trichogramma.
• Spray insecticides at recommended doses.
• Avoid indiscriminate use of chemicals.
• Intercropping with onion/garlic helps deter pests.
• Handpicking of caterpillars is effective at an early stage.
• Regular field inspection needed.
• Rotation with non-cruciferous crops lowers infestation.

Disease Management

• Common diseases: damping off, black rot, downy mildew, club root.
• Use disease-resistant varieties.
• Apply Trichoderma in the soil for fungal protection.
• Copper oxychloride spray against downy mildew.
• Seed treatment essential to prevent seed-borne pathogens.
• Destroy crop residues to stop re-infection.
• Maintain field sanitation.
• Ensure proper drainage to avoid club root.
• Crop rotation breaks disease cycles.
• Biological fungicides are safer than chemicals.

Harvesting and Post-Harvest Management

• Harvest when curds are compact, white, and firm.
• Early varieties ready in 60–80 days; late ones in 120–150 days.
• Harvest before curds turn yellowish/loose.
• Cut with a sharp knife along with 2–3 leaves for protection.
• Handle carefully to avoid bruising.
• Pack in bamboo baskets or crates.
• Store at 0–4°C with 90–95% humidity for longer shelf life.
• Can be stored for 2–3 weeks in cold storage.
• Sort and grade before marketing.
• Transport carefully to avoid damage.
