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
• 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

🔹 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

CAULIFLOWER (Brassica oleracea var. botrytis)

Basic Information

• Botanical Name: Brassica oleracea var. botrytis
• Family: Cruciferae (Brassicaceae)
• Origin: Mediterranean region
• Group: Cole crop
• Chromosome Number: 2n = 18
• Introduced in India by: Dr. Jenson from London in 1822

Climatic and Soil Requirements

• Thermo-sensitive crop

Temperature-sensitive growth stages:

• Yield: Early types: 12–15 t/ha. Mid & late types: 20–30 t/ha
• 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

🔹 Varieties

 Introduced Varieties; Improved Japanese

Selection Varieties

1. Pusa Himjyoti – Self-blanching; grown from April to July in hills
2. Pusa Snowball K-1 – Black rot tolerant
3. Pusa Ketki
4. Pusa Aghani
5. Pusa Deepali

Hybrid Varieties

1. Pusa Shubhra – Disease resistant
2. Pusa Deepali
3. Pusa Aghani

Season-wise Varieties

• Scooping = flower stalk initiation
• Blanching = white curd protection
• Pusa Himjyoti = Only variety suitable from April–July in hills
• Snowball group = Self-blanching habit
• Pusa Shubhra = Triple disease resistance
• Dr. Jenson = Introduced cauliflower to India (1822)
