How to Pollinate Corn Plant:
Increase Your Yield

Updated: October 22, 2022

Corn is a popular crop throughout the world, with over 1 billion metric tons produced annually. However, corn yield can be affected by various factors including soil quality, irrigation, and pests. One important factor that farmers often overlook is pollination. Proper pollination is essential for optimal corn yield. In this article, we will discuss how to pollinate corn plants and increase your yield.

What is Pollination?

Pollination is the transfer of pollen from the male reproductive organ (tassel) to the female reproductive organ (silks) of a flower. This process is essential for fertilization and the production of seeds. In corn plants, pollination occurs when pollen from the tassels falls onto the silks of the ears.

Why is Pollination Important in Corn Plants?

Proper pollination ensures that each kernel on the ear develops into a seed. Without pollination, kernels may not form or may be undersized, resulting in reduced yield. Poor pollination can also lead to unevenly filled ears and decreased grain quality.

How to Pollinate Corn Plants

There are two main methods of pollinating corn plants: natural and manual.

Natural Pollination

Natural pollination occurs when wind carries pollen from tassels to silks. This method is ideal for large fields where corn plants are spaced adequately apart. However, natural pollination can be unreliable in areas with low wind or for plants that are too close together.

Manual Pollination

Manual pollination involves transferring pollen from tassels to silks by hand. This method is ideal for small gardens or fields with plants that are too close together for natural pollination.

To manually pollinate your corn plants, follow these steps:

  1. Wait until the tassels have fully emerged and are shedding pollen.
  2. Collect pollen by gently shaking the tassels into a paper bag.
  3. Hold the ear of corn by the stalk and shake it to release any loose silks.
  4. Using a small paintbrush, gently brush the collected pollen onto each silk.
  5. Repeat this process for each ear of corn.

Tips for Optimal Pollination

To ensure optimal pollination in your corn plants, follow these tips:

  1. Plant corn in blocks instead of rows to increase the chances of cross-pollination.
  2. Avoid planting different varieties of corn close together as they may have different flowering times or incompatible pollen.
  3. Keep your garden or field free of weeds which can interfere with pollination by blocking wind flow or harboring pests.
  4. Water your plants regularly to prevent drought stress which can reduce pollen production and viability.

FAQ

1. What time of day is best for pollinating corn plants?

The best time to pollinate corn plants is early in the morning when the air is still and humidity is high. This is when pollen is most abundant and sticky, making it easier to transfer to silks.

2. Can you use a Q-tip for manual pollination?

Yes, a Q-tip can be used instead of a paintbrush for manual pollination.

3. How long does it take for corn to be pollinated?

Corn plants typically begin producing ears within 60 to 80 days after planting. Pollination occurs within 2-3 days after the silks emerge.

4. Can you over-pollinate corn plants?

Over-pollination is unlikely as corn plants produce an excess amount of pollen. However, excessive pollination can result in ears with many small, poorly developed kernels.

5. How can you tell if a corn plant has been pollinated?

You can tell if a corn plant has been pollinated by observing the silks. Pollinated silks will become dry and turn brown, while unpollinated silks will remain green and eventually wither away. Additionally, the ear of corn will become plump and full as the kernels develop.

In conclusion, pollination is an essential process for optimal corn yield. By following these tips and techniques for pollinating your corn plants, you can increase your yield and ensure a bountiful harvest.
