Pioneer Hi-Bred launches replant calculator

A replant calculator is now being offered by Pioneer Hi-Bred to help corn growers in that difficult situation. The tool is meant to help producers decide whether to keep their current stand or replant where their crops have been impacted by weather, pests or other issues.

The calculator is available on Mobile via the tools section, which can be accessed through the main navigation menu. It takes into account the original date for planting, original stand target and resulting plant population, and the possible replanting date. Growers are asked to consider their own likely replanting seed and input costs. The calculator presents both scenarios, current stand and replant stand, and provides estimates associated with each choice.

“We want growers to get the best yields possible with our products,” says Chuck Bremer, Pioneer agronomy e-business information manager. “Although every grower tries to target the best planting date and stand, things happen that can negatively impact the crop early in the season. The replant calculator helps growers address the tough question of whether to keep their current stand or replant to achieve a new stand that more closely meets their original yield target.”

The replant calculator is based on a long-standing chart developed by Dr. Emerson Nafziger of the University of Illinois and widely used across the Corn Belt, which illustrates the effects of planting date and plant population of grain yield for the central Corn Belt. The new calculator also takes into account the current shift to higher populations, as suggested by Pioneer research and data.
