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.T 1 (control), T 2 (potassium nitrate @ 1%), T 3 (salicylic acid @ 100 ppm), T 4 (salicylic acid @ 200 ppm), T 5 (potassium silicate @ 0.1%), T 6 (potassium silicate @ 0.2%), T 7 (salicylic acid @ 100 ppm + potassium silicate @ 0.1%), T 8 (salicylic acid @ 0.2% + potassium silicate @ 200 ppm), T 9 (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% (T 8 ) found to improve fruit quality attributes like TSS (19.70oBrix),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/cm 2 ) and reduce physiological loss in weight during storage period.Mango (Mangifera indica L.) is one of the most important fruit crops of the tropics and subtropics that belong to family Anacardiaceae, native to Indo-Burma region.It has been grown since long and leading fruit crop of India and is known as "King of fruits" due to its sweetness, richness of taste, huge variability, large production volume and a variety of end usage.Besides, having delicious taste, captivating flavour with multifarious colours, it is an excellent source of dietary nutrients and Vitamin A. It is grown in almost all parts of the world and India is considered as the largest mango producing country of the world, cultivated in an area of 2.25 million hectares with a production of 21.82 million metric tonnes [1].The area and production of mango in Andhra Pradesh with 0.33 million hectares and 3.16 million metric tonnes [1].Mango is a climacteric fruit, generally harvested at mature green stage, and ripens up during the marketing process (transport, storage etc.).However, due to the application of conventional technology for the transfer of the produce and an irregular storage period more than 30% is wasted.Short production season, short storage period and development of post-harvest diseases leading to decay are the major constraints of the mango trade.It is a crop which always requires attention and care during its postharvest handling and marketing, especially for reduction of postharvest superficial blemishes.Maintenance of proper quality fruits (TSS, Sugars, Firmness etc.,) during storage period also an important aspect now a days along with enhace shelf life of mango fruits.
