Re: How do I change the y-axis on an Excel chart from numbers towords. This will plot everything as zero values, since they are all text. You can fake it using one of these approaches: http://peltiertech.com/Excel/Charts/Y_CategoryAxis.html. http://peltiertech.com/Excel/Charts/DotPlot.html. - Jon.
First you must keep in mind that all ears of corn have an even number of rows, never an odd number. All average ears have between 12 and 20 rows. Still, it's difficult to tell at a glance whether an ear has 14, 16, 18, or 20 rows.
Most corn plants will yield at least 2 ears per stalk. Hybrids may yield more. To see if an ear is ready for harvest, look at the silks. They should be brown and dry with just a little fresh green at the base. Squeeze the husk to see if the ear inside feels plump, not skinny.
