Planting dates can have a significant impact on corn yields. In some cases, a higher seeding rate could help negate some of the negative impacts of a later planting date on yield. To compare the interrelationship of seeding rate to planting date to corn yield, this one-year study in Tifton, GA included four seeding rates of 24,000, 32,000, 40,000 and 48,000 seeds per acre in a Randomized Complete Block Design across three spring planting dates of March 15, March 31, and April 12 (n=48). Final grain yield and yield components were determined, including kernels per row, kernel rows per ear, ear length, and 100-seed weight. The greatest grain yield was found in the March 31 planting date, while across the planting dates 24,000 seeds per acre consistently yielded less than the 32,000, 40,000, and 48,000 seeds per acre. Results of this one-year study indicate that as planting date is delayed from mid-March to mid-April, an increase in seeding rate from 32,000 to 48,000 seeds per acre is necessary to stabilize yield. Complete results will be presented at the 2024 ASA Southern Branch Meeting.
