Global agricultural production faces environmental challenges such as soil salinity and water scarcity, which negatively impact crops and food security. This study proposes the use of organic amendments and Trichoderma harzianum to mitigate water and salt stress in spinach. Biometry, nutritional content, and physiological activity (Photosynthetic Rate "A" and Stomatal Conductance "Gs") were evaluated. A Split-Plot experimental design was used, with stress conditions at the plot level and amendments at the subplot level. Under salt stress, treatments with amendments and T. harzianum did not differ significantly from the Absolute Control in length (12.3 cm) and weight (34.4 g), but Vermicompost + T. harzianum showed the highest values (17.7 cm; 62.7 g). Under water stress, only Vermicompost + T. harzianum and T. molitor manure + Vermicompost + T. harzianum presented similar, but lower values. Physiological variables were affected by water stress. T. molitor manure + Vermicompost + T. harzianum mitigated stress, showing the highest Photosynthetic Rate (120.20 µmolCO2/m2s) and Stomatal Conductance (5.34 mmH2O/m2s). Under salt stress, there were no significant differences between treatments. Finally, the nutritional content was partly influenced by the initial composition of each amendment and the stress condition, with primary and secondary macronutrient content showing no significant differences at the plot and subplot levels. Sodium content was influenced by the same saline condition, regardless of the incorporated amendment, while iron content was higher in plants subjected to water stress.
