How Tall Does a Corn Plant Grow

Updated: April 22, 2022

Corn is one of the most widely grown crops in the world, and it is an important source of food, feed, and fuel. Corn plants are known for their impressive height, which can vary depending on a number of factors. In this article, we will explore how tall a corn plant can grow and what factors affect its growth.

Factors that Affect Corn Plant Height

Several factors can affect the height of a corn plant. These include:

Variety

Different varieties of corn have different growth patterns, including their maximum height. Some varieties are bred to be shorter, while others are bred to be taller.

Soil Type

The type of soil in which corn is grown can also affect its height. Corn plants grow best in well-drained soils that are rich in organic matter and nutrients.

Moisture

Water is essential for the growth of corn plants, and too little or too much can affect their height. Corn plants require consistent moisture throughout the growing season to reach their maximum potential height.

Temperature

Temperature is another important factor that affects corn plant growth. Corn plants grow best in warm temperatures, with an average temperature range between 60 and 95 degrees Fahrenheit.

How Tall Can a Corn Plant Grow?

On average, a corn plant can grow to be between 7 and 12 feet tall, but some varieties can reach heights of up to 20 feet. The height of a corn plant is determined by its genetics, environmental conditions, and management practices.

Corn plants grow in stages, with the vegetative stage being the period of rapid growth before tasseling and silking. During this period, a corn plant can grow as much as an inch per day. Once the plant reaches maturity, it will stop growing and begin to focus on producing ears.

Management Practices that Affect Corn Plant Height

Farmers can take various management practices to influence the height of corn plants. These practices include:

Plant Density

The number of corn plants per acre can affect their height. Higher plant densities can result in shorter plants, while lower densities can lead to taller plants.

Fertilizer Application

Fertilizer application can also affect the height of corn plants. Nitrogen is particularly important for corn plant growth and can increase plant height if applied at the right time and rate.

Weed Control

Weeds can compete with corn plants for resources and affect their growth. Effective weed control can help corn plants reach their maximum potential height.

FAQ Section

What is the tallest recorded corn plant?

The tallest recorded corn plant was grown in Norway and measured 30 feet and 1 inch tall.

Can corn plants grow too tall?

Yes, corn plants can grow too tall, which can make them more susceptible to lodging (falling over) during severe weather events.

How long does it take for a corn plant to reach maturity?

Corn plants typically take between 90 and 120 days to reach maturity, depending on the variety and environmental conditions.

Why do some farmers cut the tops off of their corn plants?

Some farmers cut the tops off of their corn plants to prevent them from growing too tall and falling over during severe weather events. This practice is called “topping” or “clipping.”

In conclusion, the height of a corn plant is determined by a variety of factors, including genetics, environmental conditions, and management practices. Corn plants can grow to be between 7 and 12 feet tall on average, but some varieties can reach heights of up to 20 feet. By taking appropriate management measures, farmers can help their corn plants reach their maximum potential height and yield.
