Bean lodging is a critical trait for cultivation efficiency, determining the feasibility of mechanized harvesting. Lodging resistance is assessed visually using a 5-point scale prior to harvest.

To assess the lodging resistance of common beans (Phaseolus vulgaris), a 5-point scale is used, where 5 points correspond to vertically standing plants and 1 point corresponds to severe lodging that precludes mechanized harvesting. Evaluation is carried out during the period from the initial appearance of the trait to full maturity, with a follow-up observation after 5–10 days to record any potential stem straightening.
High resistance scores are preferred for intensive farming systems that employ direct combining. Low resistance leads to yield losses due to reduced photosynthetic activity and increases the risk of pod diseases upon soil contact. The primary method for managing lodging is selecting determinate (bush) varieties with genetically determined stem strength and controlling agronomic factors, such as seeding density and nitrogen fertilizer rates.
