Corn Product Yield Response to Seeding Rate and Nitrogen Rate - Camden Point, MO

Trial Objective:

  • To evaluate the yield response of Channel® brand blend corn products to three seeding rates and two pre-plant nitrogen application rates.

Research Site Details

  • Six Channel® brand blend corn products were planted in two adjacent blocks. One block received 125 lb nitrogen/acre and one block received 200 lb nitrogen/acre. Anhydrous ammonia (NH3) was applied pre-plant on Mar. 14, 2018.
  • Each seed product was planted at 26,000, 32,000, and 38,000 seeds/acre in each nitrogen rate block.
  • Each treatment area was 6 rows wide (30-inch rows) and approximately 350 feet long.
  • The treatments were not replicated.

Understanding the Results

  • All products responded with incrementally higher yields at the 200 lb nitrogen/acre treatments as seeding rate was increased.
  • The highest individual yield for all products was exhibited at the 38,000 seeds/acre and 200 lb nitrogen/acre treatment.
  • At the 125 lb nitrogen/acre treatments, 215-75STXRIB and 218-44VT2PRIB brand blends had the highest yield at the lowest seeding rate of 26,000 seeds/acre.

What Does This Mean For Your Farm?

  • The response of corn products to seeding rates and nitrogen rates is influenced by climate, especially precipitation, and soil conditions.
  • Farmers should work closely with their local seedsman and sales team to determine the optimal seeding rates and nitrogen rates for corn products in order to maximize yield potential.
