CABBAGE (Brassica oleracea var. capitata)
  • Botanical Name: Brassica oleracea var. capitata
  • Family: Cruciferae (Brassicaceae)
  • Origin: Mediterranean region
  • Chromosome Number: 2n = 18
  • Fruit Type: Siliqua
  • India’s Status:
    • Ranks 3rd globally in production
    • Covers ~4% of total area under vegetable cultivation
    • Hybrids occupy about 30% of cabbage production area

 

Climatic and Soil Requirements

  • Climate: Cool-season crop; best suited for temperate to sub-tropical climates
  • Optimum Temperature:
    • Vegetative growth: 15–20°C
    • Head formation: 10–20°C
    • Seed production: Requires temperate regions
  • Soil: Well-drained, fertile loamy soil with pH 6.0–6.5
  • Saline soil: Increases susceptibility to black leg disease

 

Special Characteristics

  • Seed production: Occurs only in temperate areas
  • Flowering Type: Bears seed in bicarpellary pod called siliqua
  • Anticancer properties: Due to Indole-3-carbinol
  • F1 hybrid popularity: Due to self-incompatibility and cytoplasmic male sterility
  • Sauerkraut: Fermented product from white cabbage, used as anti-scurvy food

 

Growth and Development

  • Germination Temp: 20–25°C
  • Growth Arrests: Above 25°C
  • Crop Duration:
    • Early: 60–80 days
    • Late: 100–120 days
  • Seedling Raising: Thermocol plate sowing; transplanting done at 4–6 leaf stage
  • High Temp. Tolerance: Spraying CCC or SADH helps in low temp. resistance

 

🔹 Nutrient Management

  • Boron (B): Essential micronutrient. 50 ppm Boric Acid spray at flowering boosts seed yield
  • Deficiency Symptoms: Cracked stems, hollow stems, poor head formation

  • Seed rate:
    • Early: 500–600 g/ha
    • Mid/Late: 350–400 g/ha

 

Unique Features

  • Curd Development: Intermediate between vegetative and reproductive phase
  • Blanching: Done to protect curds from yellowing due to sunlight. Arrests enzymatic activity
  • Self-blanching: Present in most late (Snowball) types
  • Scooping: Removal of central curd part to promote flower stalk initiation
  • Best curds: White, compact, medium size
  • Notable Disease Resistance:
    • Pusa Snowball K-2 – Sclerotia rot resistant
    • Pusa Snowball K-1 – Tolerant to black rot
    • Pusa Shubhra – Resistant to black rot, curd and inflorescence blight
