In the process of corn planting, the problem of corn seeds failing to germinate is often encountered. This is not solely due to the corn seeds themselves, but may be caused by a combination of factors. So, under normal circumstances, how many days does it typically take for corn to germinate and emerge from the soil? Let's find out below.
How many days does it take for corn to sprout and emerge from the soil?
The first stage of corn growth is water absorption and germination, which takes about a week under suitable temperature and moisture conditions.
What causes corn to fail to sprout?
1. Seed problem
The corn seeds themselves may have quality problems, such as poor germination rates or damaged embryos, which can also prevent the corn from germinating properly. Therefore, it is essential to carefully select high-quality seeds before planting.
2. Sowing too deep
The ideal sowing depth for corn is generally between 3 and 5 centimeters. If sown too deep, such as at 7-8 centimeters or even 10 centimeters, the corn may have roots but no sprouts. This is because sowing too deep results in poor soil aeration, insufficient seed nutrients, weak growth, and difficulty in breaking through the soil to germinate.
3. Improper medication
When many farmers coat corn seeds themselves, they often use too much pesticide or apply it unevenly during coating. Areas with excessive pesticide can damage the embryo or radicle, affecting normal development and preventing germination.
4. Overly wet soil
Excessive rainfall and excessive moisture in the soil can lead to insufficient soil aeration during planting, preventing corn seeds from having a proper breathing environment and causing them to fail to germinate.
5. Underground pests
Common underground pests include cutworms and seed maggots. Without proper control, these pests can easily eat away at the buds or root growth points, preventing seeds from germinating properly.
