Question

The ideal temperature for the growth of mustard is ________________.
A. 15°C - 25°C
B. 20°C - 25°C
C. 20°C - 30°C
D. 30°C - 40°C

Answer 1

Hint: Mustard is a rabi crop and is sown from the month of October till December. The duration for harvesting is generally 80-95 days, depending on the variety of seeds sown.

Complete Answer: Mustard is a rabi crop that can be cultivated in a short growing season. The yellow mustard variety usually matures within 80 - 85 days while the brown and oriental types of seed require 90 to 95 days to grow. The ideal temperature for the growth of mustard is 15°C - 25°C while the germination temperature is a bit high 28°C. An annual rainfall more than 6000-1000 metre is sufficient for the cultivation of seed but heavy rainfall hampers the growth of the plant by weakening it during flowering.

Now let us examine the options
Option A - 15°C - 25°C is considered suitable for the growth of mustard as it helps in containing the oil content of the seed. Heavy rainfall or harsh sunlight leads to a high reduction in yield.
Option B - 20°C - 25°C is suitable for growing but the temperature below 20°C is more preferable for growing.
Option C - The temperature required for germination is 28°C more than that would result in a high reduction in yield.
Option D - High summer temperatures, 30°C - 40°C reduce growth and also decreases the quality of the seed.

Thus, the correct answer is option (A).

Note: Mustard can be raised on different soil types with a great drainage system yet is best adapted to well-drained, fertile, loamy soil. Soils inclined to crust before seedling development can cause issues. This yield would not endure waterlogged soils since development will be hindered. Dry sand and dry, sandy loamy soils ought to likewise be evaded.
