Summary: Salinity is a significant issue for food production, and biostimulants can help protect crops from yield losses. A greenhouse experiment was conducted on lettuce plants under control and high salinity conditions using Trainer (T) and Vegamin (V) PH biostimulants. The results showed an increased yield (8.9/4.6%, T/V) and higher photosynthetic performance (14% compared to control and salinity treatments). The increase in yield in salinity condition by T compared to V was significant due to the positive modulation in stress-protecting molecules like lutein, β-carotene, and flavonoids. The effects of PH biostimulants on lettuce plants’ physio-chemical and metabolic performance are formulation-dependent, but they increased plant growth under stress conditions, which can be profitable.
