Early planting hasn't historically increased yields at the NWIARDC


In 2009 and 2010, agronomists at the University of Illinois led by Dr. Emerson Nafziger studied the effect of planting date on yield at the Northwestern Illinois Agricultural Research and Demonstration Center (NIARDC). Seeds were planted in early and mid-April and in May. They found that there was no yield boost with early planting (Figure). On average, the earlier planted corn yielded close to 7 bushels per acre less than the corn planted later in April.

Dr. Nafziger, U of I agronomist, wrote a column about early planting on March 22nd titled, "Does it make sense to plant corn so early?" for the Department of Crop Sciences online journal, the Bulletin (http://bulletin.ipm.illinois.edu/article.php?id=1594).
