Don’t Panic Yet
Tyler Afrank (DSM, Region 4 – Eastern Nebraska)
25 degrees, windy, and snowing with accumulation. Sounds like something you’d see in January or February, right? Well, this was the setting in Norfolk, Nebraska today, APRIL 18th!
Nearly everyone I have talked to recently has expressed concern, disgust and even amazement with the cold, snowy weather we’ve had and how far behind things are this year. I have been getting several calls with questions regarding current soil temperatures, temperatures needed for germination, and possibilities of switching seed for shorter maturities. So, out of curiosity I looked some things up. According to University of Nebraska research, the ideal planting period for Nebraska is, on average, May 1st through May 15th. Optimal time for Northern Nebraska falls in the window from May 5th to May 20th, and from April 25th through May 10th in Southern Nebraska (Klein, B.). Most accounts in this area are confirming ground temperatures in the mid to upper 30s at the present time. While most sources agree a ground temperature of 50 degrees is necessary for germination (University of Nebraska recommends 55 degrees), we need some heat before seed is put into the ground. As far as switching varieties goes, give it some time. We have several weeks to go before we get to that point.
Although we are getting a later start this year than last, try to keep a few things in mind. Last year was unusually early in regards to planting dates, making it seem even later this year. Even though it is cold and wet, at least we are finally getting some much needed moisture. Try not to panic; we’re not to that point yet! Also, be sure to check out the Producers Hybrids website or Facebook page for a good article in regards to cold saturated soil effects on corn germination and emergence. Thank you for choosing Producers Hybrids, and be sure to contact your DSM, RSM, or Agronomist with any questions regarding your operation this spring.
