Irrigation

Irrigation - 3-4 days interval to maintain soil moisture at field capacity. In summer once in 2-3 days interval. Rainy and Rabi – 4-5 days interval. Method of irrigation – Furrow / Drip irrigation, Avoid sprinkler irrigation.

Weed Control

Manual weeding: 2-3 times during crop cycle

Special Crop Practices

Nipping of the apical meristem @ 30-35 days after transplanting promotes growth of side shoots. This operation increases the yield.

Diseases

Name of the Disease	Symptoms & Management
Pin Rot	Fungal Spots on leaves looks target board appearance, at high rain fall infection spread to curd cause pin rot and completing rotting of curds. Control: Fluxapyroxad 250 G/L + Pyraclostrobin 250 G/L SC 0.3 ml/L
Soft Rot	Its bacterial disease characterised by rotting of curds at excess moisture. Control: Avoid water logging, prophylactic spray of Copper Oxy Chloride 50% Wp + K Cycline (2.5g + 0.5g/L)
Black Rot	Its bacterial disease characterised by yellowish spots on leaf margin looks V shape , gradually spreads cause burning of leaves. Control: Spray of Copper Oxy Chloride 50% Wp + K Cycline (2.5g + 0.5g/L)
Down Mildew	Small brownish spots on leaves, on lower surface whitish powdery mass observed at cloudy weather, cause defoliation Spray: Fenamidone 10% + mancozeb 505 WG (2.5g/L) Metiram 55% + Pyraclostrobn 5% WG (2g/L)

Pests

Name of the Pest	Symptoms & Management
DBM	DBM causes damages to leaves by making wholes on leaves cause severe damage Control: Chlorantraniliprole 18.5% SC (0.3ml/L) Spinosad 45% SC (0.15ml/L)
Loopers	Veracious eaters on leaf Control: Chlorphyriphs 50% + Cypermethrin 5% w/w (2ml/L), Emamectin Benzoate 5% SG (1g/L)
Aphids	Suck the sap from leaves cause leaf distortion Control: Acephate 20 SP% (1g/L)

Harvesting

Harvesting starts from 60- 65 days after transplanting. Carefully cut the single inflorescence along with 8- 10 cm of pedicle length with pencil thickness. Stem broccoli is a multi-harvest crop and we can harvest 10-15 times in the crop duration.

Yield

8-10 t/ha

Parameter	Description
Zoning	Alternate dark and light colour rings are formed on the beet root. Zoning occurs due to high temperature or irregular supply of moisture.
Anthocyanin	Pigmentation in green broccoli disfigures the curd due to high temperature. Controlled by tolerant hybrids.
Bracting	Unwanted leafy growth on curds within broccoli due to high temperature and low moisture. Controlled by tolerant hybrids.
Hollow Stem	Presence of cavities within the stem of broccoli. Controlled by avoiding excess irrigation and nitrogenous fertilizer. Apply boron @ 25 kg/ha.
Cat Eye	Some of the florets on the curd prematurely break into yellow or green flower buds, resulting in curds with uneven bead size and colour. Cat’s eye occurs due to fluctuation of temperature and irrigation. Controlled by avoiding excess irrigation.
Brown Beads	Brown, small, undeveloped flower buds or "beads" on the broccoli head due to high temperature, excess moisture, and calcium deficiency. Controlled by avoiding excess irrigation. Apply Calcium Nitrate (CN) @ 50 kg/ha.
