Field Establishment

Soil requirement

Land preparation

Crop Management

Cultural practices

Weed control

Fertilizer application

Irrigation

Diseases and insect pest control

Diseases/ Pest	Symptoms	Control
Early leaf spot Cercospora arachidicola	Leaf spots with yellow rings	Use recommended fungicides
Late leaf spot Cercosporidium personatum	Black colour leaf spots
Rust Puccinia arachidis	Orange colour pustules can be seen on lower surface of the leaves
Stem rot (Southern blight, Root rot, Sclerotium rot, Sclerotium wilt) Sclerotium rolfsii	- Sudden wilting of a branch which is completely or partially in contact with the soil - Leaves turn brown and wilt - White coating of fungus myceliyum is formed near the soil level - Sclerotia of mustard seed size appear on the infected areas - The entire plant may killed later	- It is needed to treat soils and seeds chemically - Crop rotation
Bud Necrosis Disease (BND) (Tomato spotted wilt vires)	- Necrosis of the terminal bud - Plants stunt - Leaves formed on the axillary shoots show wild range of symptoms, reduction in size, distortion of limina, mottling, chlorosis	- Plant time is important. Late planting may be a cause for disease - Vector control is needed
- Leaf eating caterpillars - Termites - Thrips		Use recommended pesticides

Harvesting

Harvesting period can be decided by,

- According to the age of the variety
- When the foliage turns to yellow colour
- 75-80% pods of a plant are matured
- When the internal surface of the pod is brown in colour
