Fig. 4: Tuber yield and shade avoidance response-related traits of conventional sweet potato in the agrivoltaics system (AVS) and control without panels.

a Tuber weight per plant, b Length of vines, c Total biomass weight, d Aboveground fresh weight/underground fresh weight (T/R) ratio. *, **, and *** indicate significance at p < 0.05, p < 0.01, and p < 0.001, respectively; ns: not significant. We did not perform statistical analysis on the 49% shading experiment of conventional sweet potato because this site lacked a control site that shared the same ridge. In addition, the planting date was different from that of both the 31% shading site and its control site.
