| Most of the REPLICATED wheat row spacing research from around the world clearly documents higher yields as the row spacing decreases. I have shown lots of row spacing research in previous posts (including replicated university research and our own replicated research) which can be located with a search.
The most recent row spacing research comes from Michigan State University. This replicated research came from two trial locations in 2019 (and I think they repeated in 2020), which compared 5" rows to 7.5" rows, to 10" rows and 15" rows (see below). Please watch the YouTube video below for greater clarification on the equipment used.
