The book "Cashew Economy of India" presents a comprehensive exploration of the cultivation, processing, nutritional value, and economic significance of cashew as a plantation crop in India. Originally introduced from Brazil, cashew has become a major horticultural and commercial crop in India, particularly in regions like Ariyalur District of Tamil Nadu, where it supports numerous households both agriculturally and economically. This book highlights the grassroots-level involvement of families in cashew processing and marketing, including roadside sales of packed kernels. It further examines the integration of imported raw cashew nuts into domestic processing units, followed by grading and re-exporting activities. The authors aim to bridge the knowledge gap by documenting improved cultivation technologies, household-level practices, and the broader supply chain network. Emphasis is also placed on the nutritional and pharmacological importance of cashew, along with insights into its profitability and trade convenience. This book is designed to serve as a valuable resource for field practitioners, cultivators, policymakers, and technocrats engaged in the cashew industry.
