Influence of Seeding and Irrigation Rates on a Fontanelle Hybrids® Brand Corn Product in Northeastern Nebraska

TRIAL OBJECTIVE

  • Information is needed on how seeding and irrigation rates influence corn product performance. 

  • This study was designed to assess corn products across multiple seeding rates and two irrigation environments to help growers select products and seeding rates for the irrigation environment on their farm.

     

RESEARCH SITE DETAILS

Location Battle Creek, NE Planting Date 5/2/19
Soil Type Loamy sand Harvest Date 10/28/19
Previous Crop Corn Potential Yield (bu/acre) 215
Tillage Type Conventional Seeding Rate (seeds/acre) Variable
  • One Fontanelle Hybrids® corn brand blend was planted in a split-plot design trial with irrigation as the whole plot and corn product by seeding rate as the subplot. Treatment combinations were replicated twice.

  • Two irrigation rates were used:
    • Full irrigation (100% FI) – 7.6 inches/acre
    • 50% of FI – 3.8 inches/acre 
  • In addition to irrigation, 23.7 inches of rainfall occurred during the growing season.

  • For both irrigation rates, the corn product was planted at 32, 36, and 40K (K=000s) seeds/acre.

  • At 100% FI, the corn product was also planted at 24, 44, and 50K seeds/acre.

  • At 50% FI, the corn product was also planted at 18, 28, and 48K seeds/acre.

  • Weeds were managed uniformly, and no fungicides or insecticides were applied.

 

UNDERSTANDING THE RESULTS

  • The performance of the corn product under the different seeding rates stresses the importance of knowing the optimum seeding rate for a product (Table 1).  

  • The highest yield for 100% FI and 50% FI for the corn product was recorded at a seeding rate of 32,000 seeds/acre.

KEY LEARNINGS

  • Corn products differ in their response to irrigation amount and seeding rate.

  • Producers should consider their irrigation and precipitation environment when making product and seeding rate decisions to achieve the best yield potential on that acre.

  • Growers should consult their local seed sales team for information on how their branded products performed in the study.
