Lodging in Italian ryegrass refers to the tendency of stems to lean or lie flat against the ground, which critically reduces seed yield and the quality of green biomass.

where this is mentioned in the description.
The degree of lodging resistance in Italian ryegrass is assessed visually as a percentage of the plot area, where 0% indicates fully upright plants and 100% indicates complete lodging of the entire above-ground mass. Evaluation is conducted during the period from flowering to harvest, when the risk of stand damage reaches its maximum.
Lodging hinders direct combining, causes seed losses due to shattering, and reduces the nutritional value of the forage by impairing aeration within the canopy. Resistance to this phenomenon is closely related to the crop's morphological characteristics, such as culm strength and plant height, while excessive nitrogen fertilization significantly increases the risk of lodging.
