2021 SureSpeed™ and SureForce™ Soybean Trial – IN

What We Were Testing For: 

To determine if yield goals can be maintained through enhanced planting practices, while using SureSpeed™ and SureForce™, at reduced soybean populations. The agronomy team will conduct in-season visits to evaluate emergence and seedling depth to capture insights during the 2021 growing season. Yield data will also be collected at harvest to determine how yield goals can be maintained through lower soybean populations.

Early Season Findings:

Consistent emergence and spacing across all populations. Plants appear to be spaced well with few missing plants and few “doubles” or “triples”. 

The population treatments of this trial are shown in this AgFiniti® map. 

Trial Location:
Central Indiana

Products Tested:
SureSpeed™ and SureForce™

Crop Type:
Soybeans

96k sds/ac

72k sds/ac

We observed some height differences on certain rows, but  they were unrelated to the trial. These difference were possibly due to compaction from previous fieldwork or other unidentified factors.

Outlying Factors:

On June 18th and 19th there was a significant rain event. The field received 3.5” of rain between 8 pm and 8 am, just a few days before these photos were taken.

Additional Trial Information and Maps:

The following weather information is provided by an on-site Arable weather station.

Harvest Observations and Insights: 

This trial was replicated on 3 fields in the region. All 3 fields showed that yield could be maintained at populations lower than the grower’s standard 120 ksds/ac, resulting in better economic outcomes due to the lower input cost.  It is worth noting that, in the Field B Trial a significant yield loss occurred at the lowest population. That field as a whole saw reduced emergence due to a hard crust forming after planting, and it’s plausible that the lowest population did not have enough plants remaining to reach the field’s full yield potential. 

 The purpose of these soybean population trials is to help inform growers about opportunities to increase their profitability on soybean acres by reducing input costs, like seed costs. The combined summary showcases how populations and environmental factors play into economic decisions that growers make every day when evaluating risk and reward factors on their operation. 

This is a summarization of data collected in one year and represents only what happened across the tested field in 2021.  It is not a rigorous evaluation of factors that may or may not influence yield.  Results may not predict future performance and may not be complete.
