{Daucus carota var. sativa}

Boron Deficiency in Carrot

In the field, boron deficiency typically causes a superficial pinhead-sized discoloration just under the skin of the carrot. The greyish irregularly shaped areas are ordinarily only seen after steam peeling of the carrots and are usually removed by normal domestic peeling. Severe boron deficiency causes further symptoms to develop. The tap roots frequently split and are often brittle. Leaves may ultimately be affected, turning a red or yellow color and later, just before the growing point dies, very small leaves are formed.
