Why is seed spacing important?
Proper spacing ensures uniform emergence, optimal sunlight interception, and consistent yield potential.
What is typical corn seed spacing?
At 32,000 plants per acre in 30-inch rows, seed spacing is approximately 6.5 inches apart.
Understanding In-Row Seed Spacing
Seed spacing determines the distance between plants within a row. Accurate spacing promotes uniform competition for nutrients, water, and sunlight. In modern corn production, most operations use 30-inch rows with spacing between 5 and 7 inches depending on population.
Adjusting spacing allows growers to fine-tune population density and maximize yield potential while minimizing stress from overcrowding.
