TRIAL OBJECTIVE
Determining the optimal seeding rate corn products grown under 50% full irrigation (FI) can help a farmer maximize yield potential while reducing irrigation costs.
The objective of this trial was to compare the yields of four Channel® brand corn products planted at six seeding rates and grown under 50% FI.

- Four Channel® brand corn products were grown at six seeding rates under reduced irrigation conditions of 50% FI in Texas County, OK.
- The Channel® brand corn products were:
- 206-11STXRIB Brand Blend
- 208-38VT2PRIB Brand Blend
- 211-44STXRIB Brand Blend
- 212-90STXRIB Brand Blend
- The seeding rates used were: 18,000, 28,000, 32,000, 36,000, 40,000, and 48,000 seeds/acre.
- The trial was irrigated with 50% FI water using zone control sprinklers.
- The Channel® brand corn products were:
- Total shelled weight, test weight, and moisture content were collected to calculate yield.
- Weeds were controlled uniformly, and no additional insecticide or fungicide was applied.
- Each treatment was replicated twice and only averages are reported in this report as no statistical analysis was performed.
UNDERSTANDING THE RESULTS
Figure 1. Average yield of four Channel® brand corn products planted at six seeding rates with 50% FI, Texas County, OK. (2020) (2 replications).
For this trial, the 36,000 seeds/acre seeding rate produced the highest average yields for the Channel® Brand Blends 206-11STXRIB and 208-38VT2PRIB, and the 28,000 seeds/acre seeding rate produced the highest average yields for the Channel Brand Blends 211-44STXRIB and 212-90STXRIB.
The 208-38VT2PRIB and 211-44STXRIB Brand Blends tended to have the greatest yields across seeding rates compared to the other products under 50% FI.
KEY LEARNINGS
Selecting the right corn product for the right field when irrigation water is limited because of either pumping capacity or water allocation is challenging. However, a corn product like 211-44STXRIB Brand Blend demonstrated high end yield potential across a wide range of seeding rates in a challenging water stressed environment.
