Planter speed affect on plant spacing

Encyclopedia Article

How critical is plant to plant spacing for corn? Past research has shown variable results, with some results showing that for every 1 inch in variation from the targeted spacing, yields were reduced 2.5 bushels per acre. Other researchers report even higher losses, while others report less. National yield contest winners often state that slow planter speeds improve plant spacing uniformity and are part of their formula for success.
