Description

Scientific name

Raphanus sativus

Hybrid

F1 Shiro 0027

Soil

Being a root crop, radish requires loose and friable soil, rich in organic matter.

Land Preparation

Ploughing the soils with 2-3 times, make fine tilth with rotavator and apply recommended FYM at time of ploughing.

Spacing

15*10 cm

Climate

Ideal temperature for growth and development of quality roots in radish is 10-15.5°C. Though it can tolerate high temperature, roots develop pungency under hot weather.

Season

Rainy

Seed Rate

7.5 kg/ha

Fertilizers & Manures

Type	Quantity	Notes
FYM	10-15 t/ha
Nitrogen (N)	50 Kg/ha
Phosphorus (P₂O₅)	100 Kg/ha
Potassium (K₂O)	50 Kg/ha
Any special cases: No

Irrigation

Radish requires plenty of water from sowing to harvest. For rapid germination and subsequent production of roots, soil should be moist and loose. So irrigate immediately after sowing. If irrigation is restricted, roots will be tougher and pungent, making it unfit for marketing.

Weed Control

Manual weeding required at 20 DAS

Any special crop practices

Diseases

Name of the diseases	Symptoms & management
Alternaria blight	Causes dark yellow to black spots with concentric rings on foliage, potentially leading to a shot-hole appearance. Control : Hexaconozole 5% EC (2ml/L), Azoxystrobin 23%SC (1ml/L), Mancozeb 63% + Carbendizim 12% WP (2g/L)
Downy mildew	Appears as purplish-brown spots on the underside of leaves, with yellowing above. Control : Metalaxyl 4% + Mancozeb 64% WP (2g/L), Mancozeb 63% + Carbendizim 12% WP (2g/L)
White rust	Appears as white, raised pustules on leaves and stems. Control : Metalaxyl 4% + Mancozeb 64% WP (2g/L), Mancozeb 63% + Carbendizim 12% WP (2g/L)
Bacterial leaf spot	Appears as leaf spots often black and in severe cases several spots coalesce together forming a bigger spots which leads to reduce leaf area. Control : Streptocyclin @0.2 -0.5 gm/ltr, Copper based fungicide COC -2 gm/ltr

Pests

Name of the pests	Symptoms & management
Aphids	These sap-sucking insects can be controlled by hand-picking, spraying with a strong water jet, or introducing natural predators like ladybugs. Control : Acepahte 75 % SP (1.5 g/L), Imidacloprid 30.5 % SC @ 0.25 ml / ltr
Flea beetle	Scrap the chlorophyll content of the leaf and skeletonize the leaf. Control : Spinosad 45% SC (0.15ml/L), Bifenthrin 10 % EC @ 1.5 ml/ltr
Cut Worms	These larvae can damage seedlings by feeding on the foliage. Control : Chlorpyriphos 50% + Cypermethrin 5% w/w (2ml/L)
Darkling beetle or Rove Beetle	Eat the leaves of plant causing leaf damage. Control : Klingocide elite 50 EC @ 0.5 ML / ltr, Quinalphos 25 % EC @ 2 ml / ltr
Root Knot Nematode	Formation of nodule in the roots and affects root formation. Control : Fluensulfon 2 % G @ 5 Kg / Ha Method of application : Broad casting

Harvesting

Roots will be ready for harvest in 27-32 days after sowing. Harvesting is done manu

Parameter	Description
Forking	Radish roots may develop multiple, branching shapes, which can be caused by uneven soil compaction or excessive moisture. Control : Soil should be loose and friable, avoid clods.
Pithiness / Sponginess	This disorder manifests as a hollow or spongy texture within the radish root, often due to excessive root growth compared to the plant’s ability to assimilate nutrients. Control : Avoid calcareous soils which inhibit nutrient uptake.
Cracking / Splitting	Cracks or splits can occur in the radish root, especially if watering is uneven or if the roots are left in the ground for too long. Control : Irrigation management and timely harvesting.
Internal Browning (Brown Heart)	This is characterized by reddish-brown discoloration in the central part of the root and is linked to boron deficiency. Control : Nutrient management.
