Popcorn plants were growing real well, They look healthy and they have
started to grow their ears and have sprouted their tassels on top. the
ears appear to be about half size, they are long but only an inch or so in
diameter. Started noticing about a week ago that they that they seem to
have stalled.....I fertilized when they first started to tassel which was
about 3 weeks ago. Have 4 rows, about a dozen each row and they get full
sun. I have never grown corn before, so not sure if this is a problem.

Popcorn ears are typically smaller than sweetcorn ears. You'll get better
pollination if you plant your 48 plants in a 6x8 block instead of a 4x12.

You may not get good fill anyhow -- corn pollen is very heat sensitive at an
early stage of development (field, sweet, and I presume popcorn too) --
temps in the high 90s can produce sterile pollen.
