Some areas of our marketing footprint have started planting and are slowly progressing while others have not yet started field operations.
I wanted to get some information into your hands as many of you may have questions regarding delayed planting and switching hybrids. We do have some resources available on the agronomy resources tab of the website, but I have also included a link to a webinar that we created two years ago with Brent Minett regarding this very topic. The webinar covers both replanting and delayed planting, but the delayed planting information begins at the 14:19 mark and continues through the 30:00 mark before the Q & A session. It’s good information and I would recommend you check it out!
Webinar: Delayed Planting
In addition, I know that this is an emotional decision but the best plan for growers is to stick with their current plan. Some information from the agronomy resources page:
What Happens to Corn Planted Later?
Hybrids mature faster with fewer GDU’s when planted after the first of May.
What Are the Risks of Changing Hybrids?
In general, the benefits of planting adapted hybrids for the area more than offset the consequences if planting up to June 1. The hybrid you planned to plant was chosen for that field for a reason. If you switch to an earlier maturing hybrid that is unfit for the field, the lost yield potential could outweigh the savings on drying costs.
If planting after the end of May, drying costs could overshadow the yield benefit from adapted hybrids and it may be best to switch to earlier maturities.
You will give up some yield potential as later maturity hybrids will almost always have more yield potential than earlier maturity hybrids.
The hybrid you switch to may require different management than the one you had originally planned on planting. For example, some hybrids respond to higher populations, fungicide, or additional nitrogen. Make sure to account for these changes if you do decide to switch.
