  1. DAS: Days after sowing.
  2. Values are in Mean ± SD, n = 3.
  3. Levels of significance: ***p < 0.001; **p < 0.01; *p < 0.05; NS = not significant (Two-way Anova).
  4. Different letters in the same column denote significant differences (p < 0.05) in the concentrations of chlorophyll a, chlorophyll b, carotenoids, boron, shoot nitrogen and total phenol in Lycopersicon esculentum and Solanum melongena plants respectively (One-way ANOVA; Tukey’s test).
