The corn is getting close to black layer west of Hillsboro, North Dakota. Pioneer Field Agronomist Kevin Sinner says more growing degree days are needed for the corn to finish up. “On a good, warm day in the upper 80s and 90s, we should get about 25 heat units. As we dip into 70s, we’ll struggle to get a dozen (GDUs) each day at that rate.” The corn that still needs to dent will need 200 to 300 heat units to finish. There’s some firing on the lower parts of the corn. “If there are stalk issues, prioritize those fields first at harvest.” Hear more in the latest Pioneer Agronomy Update.
