Broccoli (Brassica oleracea var. italica)
Introduction:• Family: Crucifereae or Brassicaceae• 2n=2X=18
• Broccoli (Italian word) derived from Latin word brachium meaning an arm or branch.
• In Italy, used as vegetable from early times• In USA large part of the produce goes to freezing industry• Edible part comprises unopened green flower bud clusters along with part of
fleshy stem• All the species of Brassica contains glucosinolates (goitrogenic substance)• Broccoli is very rich in:
• Vitamin-A:2500 IU• Vitamin-C: 113mg• Calcium(Ca): 103 mg• Phosphorus(P): 78 mg• Potassium(K): 382 mg
• Also rich in Sulphoraphane (having anticancer property)
Per 100 g edible portion

Origin and taxanomy:• All cole crops originated from a common parent, the wild
cabbage or ‘Colewart’, Brassica oleracea var. sylvestris somewhere along the coasts of Mediterranean sea.
• Present day varieties developed in Italy in the past 2000 years.• Till 1660 it was referred to as ‘Colliflower’ or ‘Italian asparagus’
Climate and soil:• Broccoli is a cool season crop & sensitive to high temperatures • Grown during winters in plains and in summers in high hills• Temperature requirement:
• For seed germination: 25-30°C• For growth and development: 10-20°C• Optimum for its cultivation: 15-20°C
• Sandy loam soils, rich in organic matter having good drainage with pH 5.5-6.8 are well suited.

Sowing and transplanting: Sowing time:
• Plains / low hills: August to September• Hills & dry temperate areas: from March-April
Seed rate: 500g/ha Spacing:
• Transplanting should be done in evening hours• 60X60 cm or 60X45 cm• At higher spacing, main and lateral head size is improved
Irrigation: The amount and frequency of irrigation depends upon soil
type, environmental conditions and stage of crop growth. However, irrigation is must immediately after transplanting
of seedlings. Cole crops are shallow rooted crops, therefore they requires
frequent and light irrigations.

Manures and fertilizers: FYM: 200 q/ha P2O5: 50-60 kg/ha K2O: 50-60 kg/ha N: 80-100 kg/ha
Full doses at the time of land preparation as basal dose
½ N as basal doseRemaining ½ in 2-3 splits

Weed control: Weeds create a serious problem in the cultivation of the cole
crops due to wide spacing, higher fertility and frequent irrigations
1-2 shallow hoeings in early stages should be done to remove weeds and facilitate aeration
Pre-plant soil incorporation of herbicides like Fluchloralin (0.75-1.0 kg/ha) or pre-transplant surface application of Pendimethalin (1.0 kg/ha) controls the weeds effectively
Harvesting and yield: Broccoli may take 45-90 days after transplanting depending
upon cultivar and environment The head is harvested along with about 6-8 inch long stem Removal of primary head can extend the harvest period
because of the proliferation of lateral inflorescences Yield varies from 150-250 q/ha

Post harvest handling and storage
• At temperature 0°C and >95% RH, broccoli can be stored for 21-28 days
• Broccoli should be cooled rapidly by liquid icing in the field packed cartons
• Refrigerated transport is must for long distance transportation

DiseasesDiseases Control measures
Damping off (Pythium spp., Phytophthora spp., Fusarium spp.)
•Provide good drainage•Treat the soil with Formalin (5%)•Seed teatment with Captan (2.5 g/kg seed)
Downy mildew (Peronospora parasitica) Spray Ridomil MZ @ 3g/L of water
Black Spot (Alternaria brassicicola and A.brassicae)
Follow phytosanitary practices and spray mancozeb/iprodione @ 0.25%
Black Rot (Xanthomonas campestris pv. campestris)
Use healthy seed or give a hot water treatment to seeds at 50 C for 20 minutes. Disinfecting of seed beds with formaldehyde solution (1:7) is important.
Black leg (Phoma lingum) Spray the seedling with copper oxychloride (0.3 per cent)
