Corn Seeding Rate Calculator

The Golden Harvest® Corn Seeding Rate Calculator is a data-based tool that helps farmers estimate the most economical seeding rate for individual hybrids and yield environments per acre. Calculations are based on two or more years of data per hybrid, collected at a subset of 70 or more trial locations each year, increasing the ability to predict optimal seeding rates for each hybrid.

To see the optimum seeding rate:

  • Select a hybrid from the dropdown list.
  • Adjust grain price and seed cost sliders.
  • Tap the pilot line in the graph below for detailed information.
