Question

The delay of flowering will result due to combine deficiency of

• A. $N,K,S,Mo$
• B. $Mg,Fe,S$
• C. $N,S,Mo$
• D. $Ca,Fe,Mg$

Answer 1

The correct option is C $N,S,Mo$

Sulphur is a structural component and is required for the production of chlorophyll. Sulphur deficiency causes yellowing of leaves and delay in flowering.

Nitrogen deficiency causes yellowing of older leaves (chlorosis). Deficiency of nitrogen also causes late flowering.

Molybdenum is a structural component of the enzyme involved in nitrogen metabolism. Flower formation is inhibited by deficiency of molybdenum.

Hence, N, S, Mo delay flowering if there is deficiency.
