Question

The recommended seed rate for late sown wheat is:

• A. 75--100 kg/ha
• B. 100--105 kg/ha
• C. 125--150 kg/ha
• D. 150--180 kg/ha

Hint:

Late sown wheat requires higher seed rate because cold weather reduces tillering capacity.

Answer 1

The Correct Option is D

Step 1: Understanding seed rate.
Seed rate is the amount of seed required per unit area for optimum plant population.
It depends on sowing time, method of sowing, and seed size.
Step 2: Normal vs late sowing.
- For timely sown wheat (in November), the recommended seed rate is around 100--125 kg/ha.
- For late sown wheat (December onwards), the crop duration is shorter, and plant tillering is poor due to low temperature.
- To compensate for poor tillering, higher seed rate is required.
Step 3: Analysis of options.
- (A) 75--100 kg/ha: Too low, suitable only for irrigated timely sown wheat.
- (B) 100--105 kg/ha: This is for normal sowing, not late sowing.
- (C) 125--150 kg/ha: Slightly higher but still insufficient for late sowing.
- (D) 150--180 kg/ha: Correct, as late sown wheat needs more seeds to achieve optimum plant stand.
Step 4: Conclusion.
Thus, the recommended seed rate for late sown wheat is 150--180 kg/ha.
