Fig. 4: Optimized density and yield in field experiments.
From: China can be self-sufficient in maize production by 2030 with optimal crop management
a Distribution of experimental stations for field trials across three regions. b, c Comparison of maize optimal plant density (OPD) and grain yield (YieldOPD) between field trials and OPD-RF simulation (RF). Data are presented as mean values ± standard error. Control density: density at the control, OPD (field trials): optimal plant density from optimum treat in field trials, OPD (RF): optimal plant density from OPD-RF simulation. Control yield: grain yield with density at the control, YieldOPD (field trails): grain yield with density at optimum treat, YieldOPD (RF): grain yield with OPD from RF simulation. NE Northeast China, NCP North China Plain, SW Southwest China. Source data are provided as a Source Data file.
