[Trivia] A Quiz to Deepen Your Corn Knowledge (1–10)
What time of day is best to harvest corn for maximum sweetness?
- evening
- daytime
- morning
See the answer
morning
Corn converts starch into sugars through photosynthesis, but when the sun sets, that process stops and the sugars begin reverting back into starch. Therefore, even within a single day, corn harvested early in the morning retains more sweetness and tastes sweeter. If it’s harvested during the day, sunlight causes the sugars to start turning back into starch, so morning is best for preserving sweetness.
How many days after sowing can corn be harvested?
- about 45 days
- about 60 days
- about 90 days
See the answer
about 90 days
In general corn cultivation, you can harvest about 90 days after sowing. However, this is an average figure and may vary depending on the growing conditions and the variety. During that period, sufficient watering and fertilizer are necessary, and with proper care you can harvest high-quality corn.

What do you call corn silk?

silk thread
Corn silk is called “silk threads.” Each silk thread functions as a pollen tube, a necessary pathway through which pollen travels to form seeds (kernels). The healthier the silk threads are, the more kernels you can expect to develop.
How many corn silks are there?
- the same as real numbers
- twice the real number
- half of the real number
See the answer
the same as real numbers
The number of corn silks matches the number of kernels, and each individual silk delivers nutrients to its corresponding kernel. This structure contributes to the uniform seed formation of corn.

Corn (tōmorokoshi) came to be called “tōmorokoshi” in Japan when it was introduced from China, being named as a ‘Tang (Chinese) plant’ called ‘morokoshi.’ In ancient Japan, ‘Tang’ (Tō) referred to China, and many items were given names prefixed with ‘Tang,’ so this followed that convention. The name also derives from the appearance of many kernels attached like beans.
