Cashew is a tropical tree crop valued for its kidney-shaped nuts and the juicy cashew apple. Native to Brazil, it thrives in Kerala’s coastal and laterite soil regions due to the warm climate and moderate rainfall. Cashew is rich in healthy fats, proteins, and essential minerals, making it highly nutritious and in demand globally.

Modern high-density farming techniques have transformed cashew cultivation, allowing farmers to plant up to 500 trees per hectare instead of the traditional 150–200. This method improves land use, boosts early yield, and simplifies orchard management. Dwarf and semi-dwarf grafted varieties are ideal for high-density plantations, offering uniform growth and easier harvesting.

Cashew starts yielding commercially in 3–4 years and peaks by 7–10 years. With rising demand in domestic and export markets, especially for processed nuts, high-density cashew farming in Kerala presents a profitable, low-maintenance, and long-term agri business opportunity for progressive farmers
