Rows per ear
The number of rows on an ear will usually be even, assuming a normal environment. The number is even because of a split of the first kernel initials, thus forming two rows from one. A hybrid's genetics is instrumental in determining the potential number of rows per ear; environmental factors have a lesser influence. Yet, the amount of water received as well as varying plant populations will affect the number of kernels per row.
