Site Notes:

13;10;
Two corn products ( a 105-day RM product and a 114-day RM product) were each planted in three row configurations (30-inch rows, 20-inch rows, and    30-inch twin rows) at populations of 35,000, 40,000, and 45,000 seeds/acre.Plots were planted conventionally on May 19, 2016 and harvested on October 3, 2016.

What Does This Mean for Your Farm

13;10;
  • Each corn product responds different to planting configurations and plant populations. 
  • 13;10;
  • Data shows that yield can be affected by plant population, row configuration, and corn product.
  • 13;10;
  • We need to continue to look at narrow row planting in corn determine the optimal plant population and row configuration for each corn product in a given area. 
  • 13;10;
  • Contact your local DSM or Technical Agronomist for local recommendations on plant population and row spacing for individual corn products.
  • 13;10;
  • We will continue to look at population and row spacing here at the Learning Center to determine the optimal plant population and row configuration for each hybrid for a given area.
