Lodging of grain sorghum
Sorghum bicolor (L.) Moench subsp. bicolor
Sorghum lodging is a critical agronomic trait that determines yield losses and suitability for mechanized harvesting. Resistance to it is closely related to plant height and stem strength.
In the reference 48 varieties crop Sorghum, where this is mentioned in the description.
The evaluation of grain sorghum lodging is conducted by visually assessing stem deviation from the vertical by more than 30 degrees, as well as recording broken plants, especially at the panicle attachment point. Breeding programs utilize scoring scales to assess the severity of damage, along with a comparative method using standard cultivars to evaluate new hybrids and lines.
The negative impact of lodging manifests in direct grain loss during harvesting and a decline in grain quality due to soil contact and moisture uptake, particularly during the milk ripeness stage. The risk of lodging increases with excessive nitrogen fertilization or a deficiency of potassium and phosphorus, which are necessary for the lignification of stem tissues, as well as under the influence of autumn droughts, early frosts, and delayed harvesting.
