Effect of Foliar Spraying of Nano Boron on Qualitative Parameters of Tomato Grown in Polybags

An experiment was conducted during kharif, 2020 to know about the effect of foliar application nano boron on qualitative parameters tomato. The laid out in a Completely Randomized Design (CRD) with nine treatments comprising different concentrations (50, 100, 150, 200, 300, 400 and 500 ppm) (1g L-1) control (Without application). Each treatment replicated thrice. done at 30 45 DAT. Nano ppm (T7) recorded minimum values for TSS (4.10 oBrix), pH (4.45), total sugars (2.45%), reducing (2.22%), lycopene content (5.85 mg 100g-1) maximum ascorbic acid (24.02 100g-1), titrable acidity (0.52%) non-reducing (0.23%). Whereas (T8) significantly (5.30 (4.74), (3.27%), (3.18%), (7.03 (19.60 (0.32%) (0.09%).
