What is the recommended planting population range for corn?

The recommended planting population range for corn typically falls between 28,000 and 40,000 plants per acre, which is supported by research indicating optimal yields within this range. This population density allows each plant sufficient resources—such as light, nutrients, and water—to grow effectively while minimizing competition among plants. A higher population can lead to increased competition for resources, which may hamper growth and crop yield if not properly managed with adequate fertility and water.

In contrast, the lower ranges, such as 10,000 to 20,000 plants per acre, do not support efficient growth and yield potential for modern hybrid types, as they are often too sparse to maximize production. The very high ranges of 50,000 to 70,000 or 100,000 to 120,000 plants per acre are typically excessive for most corn varieties, potentially leading to overcrowding and diminishing returns on yield because of increased stress and competition among the plants. Therefore, the option of 28,000 to 40,000 plants per acre aligns with agronomic best practices and research findings, making it the most acceptable recommendation for achieving optimal corn yields.
