Asgrow® XtendFlex® Soybean Evaluations on Two Southern Soils

TRIAL OBJECTIVE

• Each year trials are conducted at the Bayer Crop Science Learning Center in Scott, Mississippi to evaluate the adaptation of soybean products to two very different soil types. The Buckshot site has heavy clay soils, and the Highway site has deep, sandy soils.
• Soybean crops are grown in a wide variety of soil types and this trial was conducted to measure performance across and within two of those environments.

RESEARCH SITE DETAILS

• Experimental design and data collection:
  • Non-replicated strip plot: 8 rows per plot
  • 38-inch rows on beds, twin row planted at 7.5 inches apart
  • Plot Size: 0.25 to 0.30 acre/plot with rows between 400 and 500 feet long depending on the experiment
  • Commercial machinery was used to harvest the plots
  • All yield values were corrected to a 13.5% moisture content equivalent for data presentation.
• All Field work, tillage and herbicides were per local standards.

UNDERSTANDING THE RESULTS

• 2025 Seasonal Influences
  • Soybean yields at Scott in 2025 were heavily influenced by the early season growing environment. This trial was planted on April 15 into good growing conditions, but environmental conditions changed after emergence. For the first four to six weeks, the local environment was characterized by wet, cloudy, chronically slow growth conditions. The lighter soil type (Highway site) was more heavily impacted, which has also been observed in previous years. Sandier soils in this region typically have reduced yield potential under adverse growing conditions when compared to heavier clay soils like those at the Buckshot site. This was particularly true in 2025.
  • This observation may indicate that soybean crops planted on sandier soils in the Delta should be planted into warmer, more ideal conditions. This is derived from many years of historical data comparing soybean yield potential between these two soil types. Please see Evaluation of Asgrow Brand Soybean Products on Southern Soils for data from 2019, 2021, 2022, 2023, and 2024.
• Yield Performance
  • Highway Site (lighter sandy soil)
    • Yield values ranged from 35 to 69 bu/acre
    • Average yield across all products was 49 bu/acre
  • Buckshot Site (heavy clay soil)
    • Yield values ranged from 64 to 90 bu/acre
    • Average yield across all products was 80 bu/acre

KEY LEARNINGS

• Soybean yield potential varied across the two tested soil types. The Buckshot site (heavy clay soil) demonstrated higher yield potential than the Highway site (lighter sandy soil). This is consistent with results from previous years.
• Early season stresses particularly impacted soybean yield potential in the sandier soils.
• Asgrow® brand appears to have a selection of well-adapted soybean products for both tested production environments. Some soybean products appear to be better adapted to one environment compared to the other.
