The “Normal” Pattern of Corn Forage and Grain Development

Dr. Joe Lauer, UW-Madison Agronomy and Extension State Corn Specialist

The Kernels

  • Corn exhibits a “double peak” for corn silage quality during its life cycle with the first NDFD peak at R1 and the second starch content peak at R5.5.
  • Corn as a forage crop reaches maximum yield and quality values at nearly the same time (R5.5).
  • At harvest (R5.5), the wettest plant part is the lower stalk, while the driest plant part is the grain. Adjusting the cutter bar can change forage moisture 3 to 4% points to better target the recommended moisture for the storage structure.
