Data of accumulated biomass and architecture indices (AIs) for the better architectures selection.

The Biom is accumulated biomass, Rel Bios is the type of relationship between accumulated biomass, LPC is a positive linear correlation, QC is a quadratic correlation, Lower B is the lower bound of AIs of good plant architecture, and Upper B is the lower bound of AIs of good plant architecture. The α-loose index (α-LI) is the radius of the cylinder where the proportion of the total leaf area reaches the critical proportion when is 50%, α-LI denoted by 50%-LI, while 90%, α-LI denoted by 90%-LI. The PD is the planting distance. The r-compact index (r-CI) is the proportion of the leaf area included in the cylinder with a radius of r (when r equals half of the planting distance, r-CI is denoted by H-CI, while r is a quarter of the planting distance, r-CI is denoted by Q-CI). WiNjVj denotes the treatment with Wi for water management practices varying from W1 to W3, Nj for nitrogen fertilizer application rate varying from N1 to N3, and Vk for variety as V1 and V2. HALP(r) was derived from overlapped digital plant architecture of three Neighbor hills.
