How much minimum temperature is essential for wheat germination and optimum temperature for crop growth in degree Celsius?

  1. 3.5°C-5.5°C and 20°C-22°C

  2. 5.6°C-7.5°C and 16°C-18°C

  3. 8°C-10°C and 30°C-35°C

  4. 10°C-12°C and 25°C-30°C

D Correct answer
Explanation

Wheat requires a minimum soil temperature of 10-12°C for proper germination, while the optimal temperature range for vegetative growth is 25-30°C. Below the minimum, germination is delayed or poor; above the optimum, heat stress reduces yield.
