How does planter speed affect plant spacing?
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. Fifteen producers in Nebraska, were part of a 2001 research project intended to compare grain yields across different planter speeds. How would planter speed affect plant spacing uniformity? Each location had three to four replications of three planter speeds: 2, 4, and 6 mph. How was the experiment conducted? The cooperators calibrated and used their own planters and equipment and managed the plots as they normally would. They also chose their own hybrid, tillage practices, etc, and harvested the grain. Yield data were obtained from on-combine yield monitor
