Removing Suckers From Corn: A Guide for Farmers

Corn is a staple crop in many parts of the world. It is used to make various food products and serves as animal feed. However, growing corn comes with its own set of challenges. One such challenge that farmers face is removing suckers from corn plants. In this article, we will discuss what suckers are, why they need to be removed, and how to do it effectively.

What Are Suckers?

Suckers are branches that grow out of the base of the corn plant, also known as the stalk. They are called suckers because they "suck" nutrients and energy away from the main stalk, which can impact the growth and yield of the corn plant. Suckers are more commonly found in indeterminate varieties of corn, which continue to grow and produce fruit until the first frost. Determinate varieties, on the other hand, stop growing and producing fruit when they reach a certain height.

Why Remove Suckers?

Removing suckers from corn plants has several benefits. First, it helps to redirect nutrients and energy to the main stalk, which can improve the overall growth and yield of the corn plant. Second, removing suckers can help reduce the risk of disease and pest infestation. Suckers provide additional entry points for pests and diseases to attack the plant, which can lead to reduced yields or even complete crop failure. Third, removing suckers can improve the quality of the corn. When suckers are left on the plant, they can divert nutrients and water away from the ears, which can result in smaller, less flavorful corn.

When to Remove Suckers?

The best time to remove suckers from corn plants is when they are small, around 6 inches in length. At this stage, they are easier to remove and are less likely to cause damage to the main stalk. It is recommended to remove suckers once a week, starting from when the corn is knee-high (around 12-18 inches in height) until tasseling begins (when the plant produces flowers and pollen). After tasseling begins, it is no longer necessary to remove suckers as they will not affect the yield or quality of the corn.

How to Remove Suckers?

There are two ways to remove suckers from corn plants. The first method is to simply snap off the sucker with your fingers. This method is effective for small suckers but can be difficult for larger ones. To snap off a sucker, locate it at the base of the leaf and gently pull it downward and away from the main stalk until it snaps off. Be careful not to damage the main stalk in the process.

The second method involves using a sharp knife or pruning shears to cut off the sucker at its base. This method is more effective for larger suckers but requires more skill and care to avoid damaging the main stalk. To use this method, locate the sucker at the base of the leaf and make a clean cut just above the point where it joins the main stalk.

Corn Harvest

Removing suckers from corn plants is an important part of corn production. It helps to redirect nutrients and energy to the main stalk, reduces the risk of disease and pest infestation, and improves the overall quality of the corn. Remember to remove suckers once a week when they are small, and use either the snapping or cutting method depending on the size of the sucker. By following these guidelines, farmers can ensure a healthy and productive corn harvest.
