Farmers across the Corn Belt are eager to start planting corn or are in the early stages of planting their 2013 crop. If cool, wet weather continues, planting will be delayed for many growers and prompt questions about switching to earlier-season corn hybrids.

Long-term research studies from DuPont Pioneer and several universities show that adapted, full-season corn hybrids usually offer the best yield and profit advantage when planting delays are not extreme.

“The cool, wet weather this spring is causing planting delays in many areas, leaving growers questioning whether they need to make hybrid maturity switches,” says Mark Jeschke, DuPont Pioneer agronomy research manager. “It is important to weigh your decision carefully. If you switch to a shorter-season hybrid too soon, you are giving up higher yield potential and profits.”

According to Jeschke, hybrid changes should be based on expected grower returns including yield, drying costs and test weight discounts. Early hybrids should be used under extreme late-plant or replant situations.

Full-season hybrids typically make full use of a growing season. Even when planted late, these hybrids often outperform early-maturing hybrids, adjusting their growth and development to reach maturity in a shortened growing season.

Long-term studies by both Pioneer and universities, which included a range of hybrid maturities across planting dates extending from April through June, have shown a clear yield and profit advantage for full-season corn hybrids.

“If growers have questions about switching, including replacement hybrid availability, they should consult their Pioneer sales professional,” says Jeschke.
