Soybean School: 15" versus 30" rows — the great debate

Should growers plant soybeans in narrower 15-inch rows or should they go wide and plant at 30 inches?

Ontario Ministry of Agriculture, Food and Rural Affairs soybean specialist Horst Bohner has been listening to the debate for years, and rather than taking sides, he likes to focus on the fact that growers can choose an option that's best for their farm.

On this episode the RealAgriculture Soybean School, Bohner notes that Ontario row-width research conducted over the years does show narrow rows typically outyield wide rows by about four bushels per acre. But research also indicates that the yield gap closes when growers "do things right" when managing 30-inch rows. That includes feeding the crop, choosing the right variety, planting early and selecting good soil types and yield environments.

Bohner admits growers will have to invest in feeding the crop to eliminate the yield gap but they also need to consider the benefits of wide rows in areas of high white mould pressure.
