How to determine the sowing date of corn
Some peasant friends mistakenly believe that the sooner the corn is sown, the better the seedlings will often be. Corn seeds can usually germinate at 6°C to 7°C, but the germination is extremely slow, sowing early, and the temperature in early spring changes violently. After the seeds germinate, they are susceptible to frost damage and lose their viability and reduce the emergence rate.
In addition, sowing too early, corn seed germination time is longer, it is vulnerable to the harmful microorganisms in the soil and rotten, causing bad seedlings. This situation is particularly prominent in the seeds of weaker germinating varieties. Appropriate sowing time for corn varies from place to place, and the time is not exactly the same. It needs to be carefully controlled. Usually when the temperature of the surface of the soil is 5 to 10 centimeters, it is suitable for sowing when the temperature exceeds 10°C.
