Oh, about 10 - 14 days.  You probably wanted an answer in feet, 
right?  It's a whole lot of feet but I don't remember how many.

I'm fond of separating different varieties by flowering date.  I've 
used days to maturity and found that  if I plant varieties so that 
they should mature approximately 2 weeks apart then everything is 
fine.  That means that I might plant two varieties on the same day if 
there's a big difference in days to maturity or I might plant a 
second variety a week later if there's little difference in how long 
it takes each variety to mature.  

Sometimes this method is a tad tricky, particularly in years such as 
last year when we have flushes of hot then cold weather.  Usually 
there's no problem at all -- that the corn doesn't all come in at the 
same time is a bonus, too.
