Growing Tips
CNSL (cashew nut shell liquid) is caustic and causes skin burns — use protective equipment during processing; mechanical shelling is safer than manual methods.
Use grafted high-yielding varieties rather than seedlings for commercial plantations; grafted trees bear fruit 2-3 years earlier.
A dry period of 3-4 months before flowering is essential for good nut set; irrigation during this dormant period reduces yield.
