Visited the nearby Pioneer Seeds research farm recently for the company's 100th year in business.
They had planted plots of corn representing different notable changes over the decades. The picture of the grass looking plants are the ancient predecessor. Next plot was a variety of Ried Yellow Dent. If you look closely you'll see a wider spacing in 2 directions. That's so a horse & cultivator could w**d in 2 directions. Yield was 24 bushel per acre back then. Today I get disappointed when yields drop below 200 bu/ac.
One thing I learned: Grandfather used to say a constant ear height was one of the first traits (other than yield) seed companies selected into their varieties. The on site plant breeders said that was more of a benefit that came along. Pre hybrid, open pollinated varieties were genetic "siblings". Hybrid seeds are genetic "clones". With siblings one can see different heights, with clones everyone is the same height.
