إنجليزي. [The research was carried out in mulched lysimeters filled with sand. Two NaCl concentrations in the irrigation water, 0% and 0.25% (w/v) (EC sub(w) 0.5 and 4.4 dS/m), were factorially combined with two watering levels, soil water potentials of -45 (HW) and -70 kPa (LW). Tomato plantlets (Lycopersicon esculentum Mill., hybrid HC01) were transplanted (4 plants/square m) on June 8. Results show that it is possible to improve fruit quality of tomato, with an acceptable yield reduction, by irrigating with saline water containing NaCl up to 4.4 dS/m. Increasing water salinity resulted either in reduced fruit size or fruit water content, whereas it caused an increase in soluble solids, Na and Cl concentration. Titratable acidity increased upon irrigation with saline water. In addition, salinity reduced P, K, Mg and NO3 concentration in fruits]

Sono stati confrontati 2 livelli di intervento irriguo (-45 e -70 kPa) e 2 di salinita' dell'acqua (0,5 e 4,4 dS/m). Entrambi gli stress hanno influito negativamente sull'accrescimento e sulla resa, ma hanno aumentato la percentuale di sostanza secca delle bacche. Lo stress salino ha ridotto il pH e aumentato il contenuto di Na e Cl; lo stress idrico ha ridotto la percentuale di N. Entrambi gli stress hanno ridotto il contenuto di K e P e di NO3 delle bacche
