Fruit yield percentage (%) produced by tomato plants during the harvesting time (30 days). After the appearance of the first ripe fruits, the fully red-colored fruits were harvested every 4 days. (A) The fruit weight percentage harvested from untreated plants. (B,C) Those harvested from plants treated with a triple or a quadruple dosage of biostimulant, respectively. Within the same panel, the different lowercase letters on the top of each boxplot indicate significant differences at p ≤ 0.05, as measured by Tukey’s multiple range test. The letter “a” denotes the highest value. For additional statistical analysis information, see Table S1.
