Apple’s Boron Deficiency (B)

It is responsible for the formation of flowers, development of fruits, growth of trees. 

Deficiency – Characterized by yellowing from the center to the tips of the youngest leaves. Evolving towards the pointers that present less development and the leaves show dark spots between the veins and the margins. Some newer leaves may be curved down and rough to the touch.

Boron deficiency often causes cracking and external cork symptoms in the fruit. This can occur although the foliage does not show symptoms, such as rosettes of thick brittle leaves and dieback of growing points. Boron deficiency causes premature fruit drop and fruit quality can be severely impacted by cork formation. If the inner cork develops too soon, the affected fruit will be severely deformed.
