Which combination of following fertilizers should be more useful in oilseed crops?

Correct option is B

Correct Answer is : B. Urea, SSP, MOP

Detailed Solution:

Oilseed crops (groundnut, mustard, soybean, sunflower, sesame, etc.) have high requirement of sulphur (S) in addition to primary nutrients N, P, and K.

Why Option B is correct:

Urea → supplies Nitrogen (N)

SSP (Single Super Phosphate) → supplies Phosphorus (P) + Sulphur (S) + Calcium (Ca)

MOP (Muriate of Potash) → supplies Potassium (K)

Sulphur is essential for:

Oil synthesis

Enzyme activity

Improving oil content and quality

SSP is therefore highly recommended for oilseed crops because it supplies sulphur along with phosphorus.

Why other options are less suitable:

A. Urea, DAP, MOP

Supplies N, P, K but no sulphur.

DAP does not contain sulphur.

C. Mixed fertilizer (10-26-26), Urea

High P and K but generally lacks sulphur.

Nutrient balance may not suit all oilseeds.

D. DAP only

Supplies only N and P.

Deficient in K and S, both important for oilseeds.

Exam-Oriented Tip :

Oilseed crops = Sulphur-loving crops

SSP is the best phosphorus fertilizer for oilseeds
