Variety traits

Lodging — Yellow Lupin

Lupinus luteus L.

This trait characterizes the ability of yellow lupin stems to maintain a vertical position during the ripening period. Resistance is evaluated on a 5- or 9-point scale, where high scores correspond to the cultivar's suitability for mechanized harvesting and direct combining.

In the reference 13 varieties crop Yellow lupin, where this is mentioned in the description.

Lodging resistance in yellow lupin is assessed visually during the plant ripening period. Agronomists record the degree of stem inclination relative to the vertical, where the highest score is assigned to plants that remain upright, and the lowest to lodged crops.

The risk of lodging increases with high seeding density, excessive moisture, and improper sowing dates, which induce stem elongation. Cultivars with a score of 4.5–5 points on a five-point scale are considered highly resistant, whereas values below 3 points indicate low suitability for mechanized cultivation.

Lodging critically affects the efficiency of mechanical harvesting, increasing losses due to pod breakage and cutter bar misses. Furthermore, contact of lodged plants with the soil leads to seed molding and uneven ripening, which reduces the overall quality of the yield.
