Correct option is C
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.
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.
