Abstract

  An field experiment was carried out to assess the effect of salicylic acid and potassium silicate on fruit quality and shelf life in mango (Mangifera indica L.) cv. Alphonso. The experiment consisted of nine treatments viz. T₁ (control), T₂ (potassium nitrate @ 1%), T₃ (salicylic acid @ 100 ppm), T₄ (salicylic acid @ 200 ppm), T₅ (potassium silicate @ 0.1%), T₆ (potassium silicate @ 0.2%), T₇ (salicylic acid @ 100 ppm + potassium silicate @ 0.1%), T₈ (salicylic acid @ 0.2% + potassium silicate @ 200 ppm), T₉ (paclobutrazol @ 3 ml m^-1).Seven years old mango orchard was selected for experiment and planted with spacing 7.5 m in square system. Results revealed that foliar application of salicylic acid @ 200 ppm + potassium silicate @ 0.2% (T₈) found to improve fruit quality attributes like TSS (19.70^oBrix), Ascorbic acid content (57.35 mg/100 g), reducing sugars (4.20%). This treatment also enhance shelf life of fruits (15.10 days), marketable fruits percentage (88.94%), firmness (4.97 kg/cm²) and reduce physiological loss in weight during storage period.
