Economically Important Part

Fruits are the most economically important part of Cashew Nut

Conditions for Cultivation

Cashew Nut is adapted to warm humid tropical conditions.

Cashew is a sun loving tree and does not tolerate excessive shade.

It can tolerate temperature of more than 36˚C for a shorter period but most favorable temperature is 24-28 ˚C.

Cashew Nuts can be grown in all types of soils from sandy to laterite and up to an elevation of 600-700m.

Cashew is best cultivated in areas with rainfall ranging from 600-4500 mm per annum.

Major Challenges

Biotic causes
- Major Pest: Cashew Weevil, Coconut Bug, Helopeltis Bugs and Tea Mosquite
- Major Diseases: Angular Leaf Spot, Anthracnose, Black Mould, Pink Disease and Damping Off .
Abiotic causes
- Internal breakdown
