Corn planting often encounters issues such as barren ears and empty kernels due to various environmental and management factors. In some cases, entire ears may lack kernels from the base to the top, with the ear bending toward the missing side, forming what is commonly known as "banana ears." Some ears have no grains at the top, while others are completely bald. Others may have only a few scattered kernels or even be entirely empty, significantly impacting corn yield. The main causes include:
1. **Inadequate Nutrient Supply**: During the critical growth stage of ear development, insufficient nutrients can lead to poor kernel formation and empty ears.
2. **Unfavorable Temperature Conditions**: High temperatures above 35°C before and after tasseling can kill pollen, reducing fertilization and causing poor kernel development. Conversely, low temperatures below 16°C during the grain-filling stage can hinder dry matter accumulation, resulting in underdeveloped kernels.
3. **Water Imbalance**: Corn requires significant water during the period from the boot stage to flowering. Drought during this time, known as "neck drought," can delay tassel emergence or cause tassels to die, leading to reduced pollen production and male-female flower mismatch. Prolonged dry weather around tasseling can also disrupt the timing of pollination, further affecting kernel set.
4. **Rainy Weather Affecting Pollination**: Heavy rain during flowering can prevent tassels from blooming properly. Pollen may swell, rupture, or clump together, losing its viability and impairing the pollination process.
5. **Overcrowded Planting**: Excessive plant density reduces air circulation and light penetration, leading to poor growth and incomplete ear development, which results in fewer kernels.
6. **Pest and Disease Infestations**: Corn is vulnerable to pests like corn borers, aphids, and armyworms, as well as diseases such as leaf spot and smut. These threats can cause premature aging of leaves, reducing photosynthesis and increasing the occurrence of empty ears.
By addressing these factors through proper nutrient management, temperature control, irrigation, pest control, and optimal planting density, farmers can significantly reduce the incidence of barren and empty ears, thereby improving overall corn yield and quality.
