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