Nutritional deficiencies

Blossom-end rot, caused by Calcium deficiency during fruit development, is probably the most common nutritional problem of tomato crops. The appearance of this physiopathy is related with low Calcium soil contents, drought or high temperature stress or high humidity. In the fruit symptoms show mostly at the blossom end of the fruit in form of a circular necrotic marks that may spread over the entire diameter of the tomato causing deformations. Due the lack of mobility of Calcium inside the plant, severe deficiency of the plants is first seen at the growth points of the plant.

Microelements are vital for providing appropriate nutrition to tomato crops. Deficiencies of Iron, Manganese, Boron and Zinc appear frequently in the intensive production systems if these elements are not applied regularly.

Iron and Manganese deficiencies are common in crops grown in limy soils and both cause chlorosis of the youngest leaves. Iron deficiency starts with yellowing at he base of the leaves and then extends over the rest of the leaf, whereas a Manganese deficiency can be identified by the appearance of pale green areas around the nerves and irregular pale green stains.

Boron deficiency appears on the youngest leaves as terminal chlorosis. Chlorotic stains appear at the edges of the leaves and in more serious cases the tips of the leaves may turn brown and necrotic. Boron deficiency during flowering causes flowers abortion and fruit deformations. Production decreases and the fruit may crack or be hollow due to lack of setting and do not ripen uniformly.
