Emerging leaves appear scorched and distorted and may cup downwards because the leaf margins have failed to expand fully.  Mature and older leaves are generally unaffected.  With a severe deficiency, flowers can abort, and the growing point may die.  Fruits from calcium-deficient plants are smaller and tasteless, and may fail to develop normally at the blossom end.  Injury from calcium deficiency can be reduced by regular foliar sprays of calcium nitrate (800 g/100 L).

Application of gypsum / foliar spray of CaSo4 2%.
