As shown in Figure 2, the lycopene content in tomato fruits was better influenced by the clayey soil x compost and sandy soil x compost interactions, compared to those of the clayey soil x compost + mineral (+76%), clayey soil x mineral (+25%), loamy soil x compost + mineral (+26%), loamy soil x mineral (+50%), and sandy soil x compost + mineral (+58%). In the loamy soil, compost fertilization led to a higher lycopene content compared with that of mineral fertilization.

Different letters mean that the values are significantly different according to [PERSON]’s test at \(p\leq 0.05\).

Different letters mean that the values are significantly different according to [PERSON]’s test at \(p\leq 0.05\). The antioxidant activity in tomato fruits was significantly higher in loamy soil with compost fertilization in comparison with both the clayey and sandy soils treated with compost + mineral fertilization; in addition, it was higher than that recorded for both the sandy and loamy soils minerals fertilized (Figure 3). In this study, the application of compost in different types of soil did not significantly affect the antioxidant activity in tomato fruits; instead, the application of compost + mineral led to higher antioxidant activity in loamy soil. Mineral fertilization led to a lower level of antioxidant activity in the loamy soil compared with that in the clayey one. Ascorbic acid content was positively affected by the sandy soil with compost fertilization, whereas the lowest accumulation was recorded under the sandy soil fertilized with compost + mineral, with no significant differences between the latter treatment and the clayey soil fertilized with compost + mineral and the loamy soil fertilized with mineral (Figure 3). The effect of compost application on ascorbic acid in tomato fruit was significantly higher when applied to sandy soil. The compost + mineral fertilization treatment best affected the ascorbic acid content in loamy soil compared with the other two textures. No differences arose between the soils with the application of mineral fertilization on the mentioned variables. As can be seen in Figure 4, the principal component analysis showed how the dependent variables responded to the interactions between the experimental treatments applied (Eigenvalues in Table 3). Specifically, for the first component, the cumulative variability indicated that the key factor was the fertilization type, with the compost, compost + mineral, and only mineral treatments progressing from negative to positive values. For the second component, the variability was primarily associated with soil type. On the upper left of the graph, variables such as pH, ascorbic acid, and lycopene were higher under compost supply in the sandy and clayey soils. On the lower left, the compost fertilization associated with the loamy soil enhanced fruit antioxidant activity, dry weight and dry residue, and plant dry matter. In the lower right-hand quadrant, the expressed variability shows that the mineral fertilizer in the loamy soil led to a higher accumulation of titratable acidity, plant dry weight, flavonoids, and phenols; higher number of rotten fruits and green fruits; and a higher average fruit weight and firmness.
