Climate change represents a significant challenge for agriculture and food security. This phenomenon contributes substantially to food insecurity by increasing the frequency and severity of abiotic stresses such as salinity. Salt stress can unfavorably influence plant development and efficiency of numerous crops, particularly in arid and semi-arid zones. Different strategies and procedures can be utilized to moderate the negative impact of intemperate salt concentration within the soil. Here, the saltiness resistance of 2 Solanum lycopersicum L. varieties (Karima and Jade) grown in an intercropping system with maize was assessed by measuring fruit production and quality. Our results show that chlorophyll a was higher in the intercropping tomato than in the monoculture plants in both control (T0 = 0 mM NaCl) and NaCl-treated varieties (T1 = 125 mM NaCl). Moreover, in intercropping systems, the variety of Karima was less affected by NaCl treatment. However, for Jade variety, its intercropping with maize increased its production under both normal and salinity stress conditions. Regarding fruit quality, pH value of Karima was higher in intercropped plants under NaCl treatment, while the Brix value was less affected by NaCl and intercropping conditions. Finally, intercropping practices significantly influenced Na+ and K+ accumulation and Karima variety showed the capacity to accumulate more K+ and less Na+.
