Cashew nut is one of the most nutritious and delicious tree nuts of the world and more than 27 countries are engaged in cashew nut production, processing and export. Cashew cultivation in the world is concentrated to the tropical portion of the globe and India, Brazil, Mozambique, Tanzania and Vietnam are the major producers. India is the pioneering country in production, processing and export of cashew kernels. In the recent years, cashew nut production and processing gains considerable momentum in many Asian, African and South American countries as well. Today, the global cashew area is over 3 million ha with a production of over 2 million tonnes. A large amount of information generated by research on cashew nut production and processing remains scattered and publications covering all aspects of production and processing techniques are rare. In this context, an attempt is made to bring all the available information on cashew nut production and processing in a single volume. We have made earnest efforts to integrate the science and techniques of cashew nut production, processing and marketing to benefit all persons concerned with cashews. Photographs and drawings are amply used to make the information as simple and easily understandable as possible.
