Introduction
Cole crop are mainly grown in cold weather during winter season in
India. Cole crops are grown by transplanting seedlings grown in
nurseries.
Major Cole crop vegetables are :
1. Cabbage
2. Cauliflower
3. Knol-khol
4. Broccoli
5. Brussel’s sprout

Cabbage: Nursery Management
Cabbage seeds are sown on seed beds and 4-6 weeks old seedlings
are transplanted into field. Production of seedlings for early plantation
requires protective structures while mid or late plantation do not.
Soil: Nursery soil should be in good tilth, free from diseases, pest and
weed. The seed beds are disinfected by drenching or sterilization.
Seed Rate: 200-500 g seed /ha. 1 g seeds= 100 seeds .
Nursery Area: 200-300 sq m for one ha plantation.
Sowing: Seed should be sow in rows at 1.5-2.0 cm depth.
Nutrients: FYM @ 500 kg, nitrogen @1-2 kg, phosphorus @ 2- 3
kg and potash 6- 8 kg applied for 300 square meter nursery area.
Irrigation: Optimum irrigation helps rapid and effective germination.
Mulching: Mulching of seed beds with straw or polythene or gunny
bags would help to retain moisture, prevent growth of weeds and
avoid washing away of seed with water. Mulching material should
be removed just before the emergence of the seedlings.
Optimum Temperatures: 15-200C.
Cabbage: Nursery Management
Cauliflower
Cauliflower is grown from seed. Nursery bed preparation and
raising of seedling depend on climatic factor.
Sowing Time and Seed Rate:
Seed Rate : 600gm/ha. 1 gram = 170 seeds
Seed Treatment: Soaking of seeds in water for 4-5 hours
improves germination.
Locality Type of Variety Time of sowing
Hilly Area Early April
Plains Mid Middle of June
Plains Late Middle of September

Raising Seedling: Seedling are raised on formalin sterilized raised
beds of size 120 cm long X 60 cm wide X15 cm height. Seed are thinly
sown 1.5 to 2 cm deep in lines with 5-7 cm apart. Seedlings are ready
for transplanting in 3-4 weeks. Seed beds are mulched with dry leaves
and removed after germination.
Seed Treatment: Seeds dipped in HgCl2 1 gm/lit/kg seeds for control
soft rot and black rot diseases.

Brussels Sprouts Nursery Management
Brussels Sprouts are propagated by seed sown in nursery beds.
Season of Sowing:
Early : August to September
Late : November to January
Spacing : 5X5 cm
Seed Rate : 300-400 gram. (1 gram = 100 seeds)
• Nursery seedlings are grown similar to other Cole crops.

Knol-khol: Nursery Management
Knol-khol is propagated by seed on nursery beds. 5-6 weeks old
seedling are transplanted to main field. Nursery management is
similar to other Cole crops
Season of Sowing:
Early: March-April in Northern Hills
Late: September - October in North India
Seed rate: 2.20 to 2.80 kg/ha. Knol-Khol
