Description

There are fundamental management decisions that give the best opportunity to maintain high yield. Understanding how a soybean plant develops through the season will provide insight into selection of management decisions that should lead to maintaining the soybean genetic yield potential. Row spacing is the third most important variable for maximizing soybean yield after variety selection and planting date. Most research from the Midwest documents that narrows (less than 30 inch) yield greater than wide rows (30 inch or greater). Despite this, the majority of the acres in Iowa are still planted in wide rows. Why7 There are many reasons to this but probably the biggest one is that very little research on row spacing has been conducted in Iowa over the last two decades. Research was therefore initiated in 2004 to investigate if we were loosing yield in Iowa using predominately wide row spacing in our current production system.
