# Corn and Soybean Yield Potential Keeps Rising. What's Holding Fields Back?

> An Iowa State University agronomist says crop genetics have far more yield potential than farms realize, citing yield contests where corn has topped 600 bushels per acre and soybeans 200. A study of 104 Midwest experiments on hybrids released 1980–2020 found harvest index rose from about 47% to 55%, with breeding gains coming from many small traits.

## Why it matters

Rising genetic yield potential supports longer-run supply growth and bearish pressure on corn and soybean prices, though realized yields remain the actual supply driver and this is general research rather than a new market event.
