In the document below, find a presentation handout that was presented at the Chrome Regional Ag Expo on August 27th regarding soybean desiccation decisions. The handout included information from a study by Science for Success determining the best timing for soybean desiccation, desiccation products, and potential benefits. Some key findings included:
- Yield loss was rare from desiccation at R7 and common at R6.5
- Desiccation at R7 did not affect protein and oil yield while R6.5 desiccation reduced protein and oil yield
- Desiccation allowed for 15 day earlier harvest in comparison with untreated control
- Greater reduction in green stem incidence from desiccation in comparison with the untreated control
To determine R7 growth stage, one mature-colored pod anywhere on the main stem should be present. For specific images, see PDF link below.
