Information is needed on how seeding and irrigation rates influence corn product performance.
This study was designed to assess the performance of three Channel® brand 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.

|Soil Type||Loamy sand||Harvest Date||10/28/19
- Three Channel® corn brand blends ranging from relative maturities (RM) of 111 to 113 were evaluated.
- The trial was a split-plot design 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 three corn products were planted at 32, 36, and 40K (K=000s) seeds/acre.
- At 100% FI, the three products were also planted at 24, 44, and 50K seeds/acre.
- At 50% FI, the three products were 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 each corn product under the different seeding rates stresses the importance of knowing the optimum seeding rate for each product (Table 1).
- As a general trend, the three products exhibited better yield performance with 100% FI.
- 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.
