The vigor of narrow-leafed lupin characterizes the crop's ability to rapidly accumulate vegetative mass during early development stages, which is critical for competing with weeds and forming green biomass.

crop Narrow-leaf lupin,
where this is mentioned in the description.
Vigor assessment in narrow-leafed lupin breeding is conducted using both laboratory and field methods. Laboratory diagnostics include determining germination rates by a specific deadline, the mass of green seedlings, and morphometric analysis of the root system, hypocotyl, and cotyledon development. Under field conditions, the indicator is assessed visually based on the speed of canopy closure and the rate at which plants transition to the stem elongation phase compared to a standard variety.
Intensive early growth allows plants to shade the soil surface faster, suppressing weed development and utilizing moisture and nutrients more efficiently during the spring period. For green manure varieties, high vigor is a defining trait, as it enables the accumulation of sufficient biomass within a short period, typically 50–60 days after seedling emergence.
