  • The trial was arranged using a randomized complete block design with four replications. The only treatment factor was the soybean product.

Yield, lodging rating, and green leaf/stem rating by Asgrow® brand soybean products planted into overwinter-mix cover-crop residue were taken. All soybean products in this trial contain XtendFlex® Technology (XF).

XtendiMax® herbicide with VaporGrip® Technology has been classified as a restricted use pesticide and must be used with VaporGrip® Xtra Agent (or an equivalent volatility reduction adjuvant).

  • The total rainfall accumulated during the 2023 soybean growing season was 12.6 inches. This trial was implemented under an overhead pivot irrigation system and the total irrigation water applied was 6.0 inches.

UNDERSTANDING THE RESULTS

  • The highest average yield was obtained with Asgrow® AG26XF3 brand at 64.1 bu/acre. The lowest yield was obtained with AG26XF4 brand at 41.1 bu/acre, 35.9% less than AG26XF3 brand (Table 2).
  • Plant lodging was significantly different between Asgrow® products. AG23XF2 brand had the lowest average rating (1.0) while AG27XF4 brand had the highest (2.5) (Table 2).
  • Green leaf/stem was also significantly different between Asgrow® products. The lowest scoring products were AG26XF3 and AG28XF3, with an average score of 1.0. AG27XF3 had the highest score with an average of 3.3 (Table 2 and Figure 1).

Yield, lodging rating, and green leaf/stem rating by Asgrow® brand soybean products planted into overwinter-mix cover-crop residue were taken. All soybean products in this trial contain XtendFlex® Technology (XF).
