BECK’S Kentucky Corn Planting Date Study - 2014
Purpose:
To evaluate the performance of a mid-season and a full-season hybrid planted on several dates throughout the growing season. The long term goal of this study is to gather several years of data to help our customers find the optimum planting date range for corn.
Summary:
The ten-year average trend for optimum planting dates for corn remained the 3rd week of April through the 1st week of May for the Kentucky PFR farm and surrounding areas. The ten-year study data shows less than a 6 Bu./A. difference if planted between the dates of April 18th and May 10th. This year’s study showed that the planting dates of April 24th and May 7th averaged a yield of 226 Bu./A. while the remaining dates of May 20th, 27th, June 2nd and 14th averaged a yield of 169 Bu./A. That is a difference of 57 Bu./A. between the two planting date group averages. Overall, the 2014 data replicates the 10 year data perfectly. While there were some good yields at later planting dates, the best averages fell in the 10 year average planting date window.
