What is the row spacing for corn?

In conclusion, 20-inch row spacing in corn has shown to provide a comparable yield and even a yield advantage to the typical 30-inch row spacing. If narrow row spacing is feasible, there could be benefits for both corn and soybean yields, as well as benefits for weed control and soil moisture retention.
