Boron Deficiency in Sugar Beet

Boron deficiency characteristically causes the death of the growing point and the development of a black heart rot. Before the deficiency has reached this stage, the leaves, which may have cracked petioles, will have become progressively smaller and somewhat misshapen. After the death of the growing point, small bunches of leaves develop in the older leaf axils and the crown is very liable to become hollow and rot.
