SODIUM CHLORIDE AND SILICON AFFECT YIELD AND QUALITY OF TOMATO FRUITS

Tomato (Solanum lycopersicum L.) is a glycophyte species with medium sensitivity to salts, tolerating electrical conductivity values in the soil solution of up 2.5 dS m-1. Silicon (Si) beneficial element that can act as an inorganic biostimulant plants subjected salinity. In this research, main effects two study factors were evaluated: a) salinity by NaCl (0, 50, and 100 mM) nutrient b) biostimulation Si, applied leaves 75, 150 mg L-1), well interaction both on yield quality fruits second cluster tomato cv. Río Supremo grown hydroponically under greenhouse conditions. Yield was significantly reduced saline treatments, not affected application silicon. Compared control, concentrations evaluated fruit pH value 6.2 %, but increased titratable acidity (TA) 64.8 (EC) 72.9 total soluble solids (TSS) 80 %. Consequently, treatments TSS/TA ratio, compared control. The 75 Si L-1 through 0.6 while dose EC ratio fruits. treated 50 mM doses increase recorded, TA values. NaCl. It concluded combination silicon improve some attributes
