Boron deficiency in cashews

The first sign of boron deficiency in cashews is the swelling of the terminal section of the stem, which is followed by a stem necrosis in the same region. Necrotic spots may occur at random over the leaf surface. The youngest leaves tend to be deformed, being narrow and curled. When the deficiency is severe, the growing point dies back and axillary shoots develop.
