Comparison of manually measured lateral growth (LG) using a meter scale (x-axis) and derived LG (y-axis) in 2017 using: Reg-3: LG = 254.26 × NPPR + 136.76 × NCPI-92.73 × NGRDI-82.78 × PPR-144.24; Reg 4: LG = 3372.55 × (PPR × NPPR × NGRDI × NCPI) + 19.96. ANN-3: PPR, NPPR, NGRDI, and NCPI as predictors of LG; ANN-4: product of PPR, NPPR, NGRDI, and NCPI as predictors of LG. Each point on the graph represents LG of every genotype at each of the days after planting (DAP) averaged over six replications. The bar chart represents four DAP (x-axis) and P-value (y-axis) derived from paired t-test of manually measured LG using the four models. The P-values lower than 0.05 means the manual LG was different from model derived LG. The box and whisker plots represent the error statistic of estimation models at different DAP. In each box, the central mark is median, and the lower and upper edges denote the 25th and 75th percentile of errors respectively. The whiskers extend to the most extreme data points not considered outliers. Outliers not shown on the chart for clarity.
