For farmers in the country’s breadbasket, it’s always more
important to get the corn crop planted and underway before anything else, and
that includes soybeans… Corn has been
off to a slow start this year due to the drought conditions, and then the
floods that have inundated the Mississippi River and its tributaries this
spring. When the ground is too wet, as
well as too dry, it makes it very hard to get seeds planted under optimum
growing conditions.
Early planting of soybean crops helps improve yield potential
and is definitely preferred, but corn loses yield faster than soybean so it’s
important to take care of that crop first and get it planted. The period from mid-April to the first week
of May provides the best chance for higher yields for both crops. If waiting
until the end of May to plant soybeans, there is a loss in potential
corresponding to about 15$. However, for
corn crops, that loss in potential rises to 25% for planting that late in the
season.
In cases of high drought conditions early in the season with
adequate rain in July and August, early planting can actually decrease
potential yields since extended stress through flowering causes the plant to lose
its ability to respond favorably to improved conditions once they appear. On the other hand, an early wet season
followed by dry weather actually benefits early planting and the yields
expected.
Hopefully this season will be much wetter than the last year
or two, and so far it’s definitely an improvement! However, it may take quite some time to
overcome the incredibly dry stretch we’ve had to deal with in many states in
the U.S. recently. “Normal” conditions
may require a new definition and new reality for many North American farmers.
