The photo above is very depictive of 40% of Southwestern Ontario's corn crop that was planted between May 12 and May 19th.Though silking and tassle emergence on the 30th of July is not early it does indicate the lateness of this years crop.Another 30% will not flower or pollinate until August 7th -10th.It takes roughly 60 days from pollination to reach physiological maturity.That means at least 30% of Southwestern Ontarios corn crop will need until Oct 10th to safely reach maturity. Grain moisture contents at maturity are genearlly in the 32-33% moisture range.An open October will be needed to ensure any kind of drydown.
