where this is mentioned in the description.
The concept of vigor for tomatoes combines biometric observations of leaf mass, root system, and lateral shoot development. This indicator is closely linked to the genetically determined plant habit, whether indeterminate or determinate, which dictates the fruiting potential.
In agronomic practice, vigor is used as an indicator of plant status. Weak vegetation indicates a deficiency of resources or root problems, whereas excessive vigor ("lush growth") suggests an imbalance in nitrogen nutrition or environmental factors, requiring adjustments to plant training and fertilizer application intensity.
