Early vigor
The ability of seedlings to rapidly establish vegetative biomass and develop a robust root system during the initial stages of growth.
Также говорят: seedling vigor, early growth rate, emergence energy
Early vigor is a vital agronomic trait that enhances a crop's competitive edge against weeds. By achieving rapid canopy closure, the crop shades the soil surface, effectively suppressing weed emergence and reducing the need for chemical control.
This trait is particularly important when planting in cool or moist conditions. Crops with high seedling vigor demonstrate better establishment, allowing them to overcome environmental stressors that might otherwise lead to crop failure or uneven stands.
Common mistakes include incorrect sowing depth and failure to manage soil fertility levels during planting. Improper depth forces the plant to deplete its internal reserves before reaching sunlight, significantly weakening the seedling.
