Despite
planting delays for some Corn Belt areas, still too early for
hybrid maturity switching - Pioneer Hi-Bred, university studies
show yield, profit advantage over switching hybrids |

Recent cool, wet weather has some growers across the Corn Belt
anxiously waiting to get into their fields to plant their 2009
corn crop. Planting delays can limit the number of growing days
for the crop, prompting questions about switching to earlier
hybrids.
Long-term research studies from
Pioneer Hi-Bred, a DuPont business, and several universities
show that adapted, full-season corn hybrids usually offer the
best yield and profit advantage when planting delays are not
extreme.
When wet weather significantly delays fieldwork and planting,
hybrid maturity switches can become an issue. However, Pioneer
experts say hybrid changes should be based on expected grower
returns including yield, drying costs and test weight discounts.
Switching to earlier-maturing hybrids should be used under
extreme late-plant or replant situations. But changing to
earlier products too soon may result in serious yield and profit
penalties. 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 hybrids. For additional
