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