Details:
Around 25-50% of soybean plants at this site were found to be lodged at the R8 (full maturity) growth stage. This research field was planted in late-April and early june with maturity group 5 soybeans. Plants can be seen tangled up with each other and many plots are laid down to the ground. It is worth noting that this environment experienced damage fromHurricane Debby in early August, and more recently by Hurricane Helene.
Conclusion:
Soybean lodging can be caused by strong winds and by water flow across the field. There are two types of yield losses associated with lodging, including restriction of maximum physiological development (reduced photosynthesis in more productive leaves) and harvest loss. Harvest loss from lodging can range from 3-10%.
Growers should follow the recommended seeding rates for your location and planting date. Closely inspect scout fields after heavy flooding or storm damage to estimate potential losses and monitor for other potential issues that may arise.
