Early Ground Cover
Early growth cover (EGC%) was measured at 33 DAS. CoverageTool(Merchuk et al., 2019) was used to quantify ground coverage by canopy in
percent for each plot. A set of photos was taken vertically from above
the plots under the same settings (height of camera from the ground,
light, same camera, Fig S4). Then, the canopy colors were sampled to be
taken into account (foreground), whereas the bare soil brown shades were
not selected (background).
