Cashew is one of the following fruits that is grown in the semi-wild form in the wasteland of peninsular India but is one of the largest foreign exchange-earners.
Commercial cultivation of cashew is taken up in eight states of our country mainly on the west and eastern coast viz., Andhra Pradesh, Goa, Karnataka, Kerala, Maharashtra, Orissa, Tamil Nadu and West Bengal.
Cashew farming is reasonably profitable but farmers could take it a step ahead to increase profit by over 200% with effort. The Cashew industry in India exports cashew kernels to more than 60 countries in the world.
