The 2010 Variety
Report Card has been mailed
out to our producers. The
choices for cotton varieties
are many and there are at
least a dozen varieties that
are available and fit well
in our region. Generally,
the varieties that I have
listed as favorable for our
region range from very early
and fast in maturity to
about a mid-season type
variety.
2009 reminded us why it is
important to limit the
acreage of a full season
type variety and to be sure
and plant the varieties that
take longer to mature first.
For
Virginia, the idea of
planting the early varieties
first and the full season
varieties last to spread out
the harvest season does not
work well like it does for
corn. A couple of reasons
for this is that we
typically start planting on
light soils which are more
drought sensitive and early
varieties are generally the
shorter and more determinant
varieties and as a result,
will have a high risk of
premature cutout when
planted early on light
soils. Likewise we move to
the heavier and stronger
land as the soils warm up
more in May and these are
the soils that typically
produce taller and later
cotton. The full season
varieties planted late on
these stronger soils are at
greater risk of not reaching
full maturity and growing
too large.
Two top varieties that fit
these two extremes for us
are FM 1740 for the example
of an early variety that is
short, and Dynagrow 2570 is
an example of a taller
variety that is more of a
medium type maturity. My
recommendation is to
start planting a medium to
medium full variety like DG
2570 and try to
finish planting this variety
around the 10th of May. FM
1740 which is short and very
early will be a top yielder
when planted in May on a
soil that typically produces
good vegetative growth. The
early varieties are
definitely preferred as we
get in mid to late May or
for replanting.
