## 4 Discussion  
In recent decades, there has been an increasing global concern regarding environmental and soil health. Consequently, modern agricultural practices are being aimed to minimize soil depletion and preserve its fertility and structure, avoiding the excessive use of synthetic

Among the agronomic techniques under current development, prominence is being gained by the utilization of compost, which derives from numerous matrices and is produced by a wide range of techniques [10]. A comprehensive review conducted by [PERSON] et al. [33] elucidated the varying interactions between composts, obtained from different matrices or through distinct techniques, with field crops due to the diverse soil factors, e.g., the microbial community, pH, aeration, water content, nutrient availability, and carbon/nitrogen ratio. A study conducted by [PERSON] et al. [21] demonstrated that various types of compost exhibit distinct effects on soil, particularly in terms of its aggregates and microbial flora, enhancing its suitability for plant growth. In this study, significant interactions between soil texture and fertilization type were observed only for qualitative variables. The yield and fruit number were higher in the loamy soil, probably due to the plants' better utilization of both water and nutrients, particularly nitrogen [34]. This statement is supported by the higher mean fresh weight and dry weight of the plants grown in the loamy soil, resulting in increased water content in the fresh weight and a higher concentration of organic and inorganic molecules in the dry weight, respectively [35]. The number of (rotten) waste fruits could have been due to the lower water availability in loamy soil. Compared to other soil types, clayey soils often have higher potassium levels, thus increasing the availability of this element [36], which generally relates to a decreased amount of waste (green) fruits that are unfit for the tomato market. Some studies have demonstrated that specific compost types can exert significant impacts on crop performance after a long period [37, 38], contingent upon the composition of the compost matrix [39, 40]. In the present investigation, the compost did not exhibit any positive effects on the yield and growth parameters, except for an enhancement of the plant dry weight. In the study conducted by [PERSON] et al. [41], a positive correlation was observed between soil phosphorus (P) content, titratable acidity, and dry residue in the fruit.
