Leaf fresh weight, fruit fresh weight, leaf content of chloride, nitrate, sodium ), and the potassium to sodium ratio. MicroTom plants were harvested at 90 days after sowing (DAS) after being fertigated since 35 DAS with a 100% or 70% basic nutrient solution (BNS), in combination with three salinity levels of 0 (white bars), 42.5 (grey bars), and 85 (black bars) mM NaCl and two different commercial two commercial Ascophyllum nodosum extracts, Rygex at 2.5 mL L⁻¹ and Superfifty (SF) at 2.0 mL L⁻¹. Control (Ctrl) was without biostimulant. The values are mean ± S.D. (n = 5 for morphological traits and n=3 for the ion measurements). Significance of the main factors (nutrient solution, biostimulant and salinity) and their interactions is shown in Table 1 and Table 2.
