Leaf Area Index (LAI) Plateau at High Plant Density

The maximum Leaf Area Index (LAI) per unit area showed a significant increase with increasing density until it reached a plateau at approximately 6.0. This indicates that beyond this density, further increases in plant density do not result in a corresponding increase in LAI. This finding suggests that there is a maximum LAI that can be achieved within a given area, and that this maximum is determined by the ability of the plants to capture light and photosynthesize effectively.
