Data analysis
Data were analyzed using agricolae and tidyverse R packages for Analysis of Variance and plotting as described in (Wickham 2016). The resulting means were separated using Tukey’s honest significant difference (HSD) test at a 5% level of significance, and box plots were generated using ggplot2 (Wickham et al., 2019). Area Under Striga Progressive Curve (AUSNPC) was determined based on methods described in (Simko & Piepho 2012) and customized R scripts.
