    Question

    Whiptail in cauliflower is due to the deficiency of:

    A.

    Copper

    B.

    Iron

    C.

    Molybdenum

    D.

    Calcium

    Correct option is C

    The Correct Answer is: (C) Molybdenum
    Explanation:
    Whiptail in cauliflower is a characteristic disorder caused by molybdenum deficiency. It leads to narrow, distorted, strap-like leaves, and sometimes results in the failure of curd formation. Molybdenum is essential for nitrogen metabolism and enzyme activities; its deficiency disrupts normal leaf development.
    Information Booster:
    • Application of molybdenum fertilizers like ammonium molybdate can correct the deficiency.

    • Symptoms include chlorosis of young leaves and the production of thin, irregular leaf structures.

    • Proper soil pH management (liming acidic soils) helps prevent molybdenum deficiency.

    Additional Information:

    • Copper: Deficiency leads to dieback and leaf tip wilting.

    • Iron: Deficiency causes interveinal chlorosis (yellowing between veins), especially in younger leaves.

    • Calcium: Deficiency causes disorders like tip burn in cabbage and cauliflower.
