What are the latest reasons why corn does not form ears?
Corn encounters many, many problems during its growth process. The most common problem that many farmer friends encounter during planting is that corn does not tassel, which leads to corn not forming ears. So why does corn not form ears? Today the editor will explain to everyone the reasons why corn does not form ears.
1. Planting too densely
When planting corn, many friends plant corn very densely in pursuit of high yield, but when the corn grows to human height, too small a spacing will affect the ventilation and light exposure of the corn. The corn plants will compete with each other for nutrients and will also be unable to carry out photosynthesis, thus causing the corn not to form ears. In fact, too small a spacing will not only cause the corn not to form ears, but will also produce many disease problems. If you want high corn yield, moderate density is best.
2. Water shortage and drought
Although corn is a crop of the north, like other crops it also greatly needs water. When corn grows under very dry conditions, its flower spikes cannot emerge or emerge very slowly. At this time, the flowering periods of the male tassel and female ear of the corn will differ and not meet, so ears cannot form. Therefore, in the process of planting corn, irrigation is an important step. When drought occurs, irrigate frequently to avoid the corn failing to form ears later.
3. Damage from pests and diseases
Although pest and disease damage is not the direct cause of corn failing to form ears, pests and diseases will affect the growth of corn and thus indirectly lead to problems with ear formation later in the corn. Corn has relatively more pests than other crops, such as corn borer, armyworm, and so on. When these pests are found, apply the right treatment promptly.

4. Seed problems
Many reasons for not forming ears are because, when sowing, the seeds chosen were seeds that do not bear fruit. This kind of seed is called “male corn.” This kind of seed will grow wildly but will not tassel, so it cannot form ears. The reason this kind of seed appears is that the seed's metabolism is out of balance and its transport mechanism is obstructed, so nutrients cannot be transported, and it lacks nutrients and does not develop. Therefore, when choosing seeds, everyone should choose seeds with plump kernels and bright, glossy outer skins. This will avoid this situation.
The above four points are the four common reasons for corn not forming ears that the editor has compiled. In fact, apart from seed problems, the other three points are all caused by improper care during the planting process. As long as you carefully observe the condition of the corn, through irrigation and fertilization, these can all be controlled very well!
