What causes corn to fail to produce ears?
Corn encounters many, many problems during its growth process. The most common problem many farmer friends encounter during planting is that corn does not tassel, which leads to corn not producing ears. So why does corn fail to produce ears? Today, the editor will explain to everyone the reasons why corn does not produce 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 density will affect the ventilation and light exposure of the corn. The corn plants will compete with each other for nutrients and cannot carry out photosynthesis, thus causing the corn not to produce ears. In fact, too small a density will not only cause corn not to produce ears, but 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 tassels 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 coincide, so ears cannot form. Therefore, in the process of planting corn, irrigation is an important step. When drought occurs, irrigate frequently to avoid corn failing to produce ears later.
3. Damage from diseases and insect pests
Although damage from diseases and insect pests is not the direct cause of corn failing to produce ears, diseases and insects will affect the growth condition of corn, thus indirectly leading to problems with ear formation in the later stage of corn. Corn has relatively more pests than other crops, such as corn borer, armyworm, and so on. When these pests are found, the right remedy should be applied promptly.

4. Seed problems
Many reasons for not producing ears are because, at sowing time, the seeds selected were seeds that do not bear fruit. This kind of seed is called “male corn.” This kind of seed will grow frantically but will not tassel, so it cannot produce ears. The reason this kind of seed appears is that the seed's metabolism is out of balance, and the transport mechanism is hindered, causing nutrients to be unable to be transported. Lacking nutrients, it does not develop. Therefore, when choosing seeds, everyone should choose seeds with plump kernels and bright, glossy seed coats, so as to avoid this situation.
The above four points are the four common reasons for corn not producing 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, these can all be well controlled through irrigation and fertilization!
