Harvesting Maize - Quality Control

Finding our way through the maize crop... I didn't manage to get lost.

When sweet corn is ready to harvest, the husk will still be wrapped tightly around the ear; the silks will be brown.

 Is the maize ready to harvest???  Maize is like corn, however has a lot starch and therefore does not taste as sweet as sweet corn.  Also maize is harvested when the cob is a lot drier than sweet corn.Also the kernels on maize are a bright yellow and a lighter yellow on sweet corn.

To tell whether the maize is ready to harvest and the dry matter is between 30-38%.  The milk line technique is used.  This is where on one kernel a sharp object (ball point pen tip) is pushed in and  run the length of the kernel and note when the pen goes from solid starch to milk (liquid) starch.  It should do this 2/3 of the way down the kernel if it ready for harvest.
