How to prevent corn shortage

How to prevent corn shortage

Corn ear abnormalities, often referred to as "Saitama" in some regions, are primarily caused by several factors related to pollination and environmental conditions. One of the main causes is premature silking of the female ear, which results in a limited amount of viable pollen available for fertilization. Additionally, high temperatures combined with dry weather during the flowering period can reduce pollen viability and lead to poor pollination. In some cases, only a small number of silks receive proper pollination, resulting in barren or underdeveloped kernels. Another common issue is the lack of grain at the base of the ear or at the tip (known as "bald tip"). This occurs due to several reasons: First, there is a variation in silk emergence across different parts of the ear. The central silks emerge first and have more opportunities for pollination, leading to well-filled kernels. However, the basal silks tend to emerge later, often missing the window for effective pollination due to delayed pollen availability. Second, improper planting density can lead to competition for nutrients and water, especially when phosphorus levels are low, which increases the likelihood of bald tips. Third, insufficient moisture during critical growth stages also contributes to this problem. Lastly, certain corn varieties may naturally be more prone to bare tips due to their genetic characteristics. In some cases, one side of the ear develops fully while the other remains empty, forming a curved or deformed ear known as "half lamelon." This typically happens when pollination is delayed, silks become excessively long, or if there are continuous rainy days that interfere with even pollen distribution. The top of the ear may also show a lack of grains due to potassium deficiency in the soil, which disrupts the plant's ability to accumulate starch properly. This physiological blockage leads to underdeveloped kernels at the upper part of the ear. To prevent these issues, it's essential to manage irrigation and fertilization effectively. Ensuring adequate water and nutrients, especially during the flowering and filling stages, is crucial. A balanced application of nitrogen, phosphorus, and potassium should be prioritized. Planting density must be carefully managed—too dense planting can hinder proper pollination. Additionally, weak seedlings should be closely monitored and nurtured to ensure uniform growth and timely silking. If late development or unfavorable weather conditions occur, artificial pollination techniques can be used to improve kernel set. Finally, regular pest and disease control measures should be implemented to maintain overall plant health and productivity.
