At what temperature does corn need soil for germination?

• A. 8°C
• B. 10°C
• C. 15°C
• D. 5°C

Answer: (B)

Corn requires a minimum soil temperature of approximately 10°C for effective germination. At this temperature, the biochemical processes necessary for seed activation and seedling development initiate, allowing for proper growth and establishment. If the soil temperature is lower than 10°C, germination may be delayed, resulting in poor seedling emergence and ultimately affecting the overall yield and health of the corn crop. Soil temperatures above 10°C generally lead to faster germination rates and healthier seedlings, as the conditions become more favorable for nutrient uptake and root development. Maintaining soil temperature within this optimal range is crucial for farmers to ensure timely planting and maximize crop productivity. Therefore, the choice of 10°C reflects the necessary conditions for corn germination in agricultural practices.
